I'll add +more over time. See them +`here `__ + +Asking for refunds +------------------ + +If you have bought the iOS version of the app, it doesn't look like I +can process a refund anymore. If any developer knows how, please let me +know. Apple wants you to contact them directly using +`this `__ link. + +For Android: If you're not happy with zmNinja and have bought the app, +please `send me an email `__ **with your +order id**. + +Note that depending on how long ago you made the order, I may not be +able to refund. Its not my policy - The app/play stores disable the +refund option. For example, I could not refund an app a user purchased 2 +years ago. + +Also, please read `Things you should own up +to <#things-you-should-own-up-to>`__ + +Things you should own up to +--------------------------- + +Read the app description +~~~~~~~~~~~~~~~~~~~~~~~~ + +Both the Apple and Android stores have a clearly visible note on the app +description that it requires a working API for ZoneMinder. If you are +not willing to ensure the API works, please save yourself and me time. +I'm sorry this is the first post, but I get emails from too many +entitled/rude folks about APIs not working. Not my problem. Read below. +Breathe. + +Try before buy +~~~~~~~~~~~~~~ + +Some users legitimately look around for an option to try before they buy +and they are not savvy enough to `download the +code `__ and compile (:doc:`source`) for +themselves. Fair enough. In that case, `download the Desktop +version `__ of +zmNinja. It's free and is the same code as mobile. Make sure the desktop +version works before you buy the mobile version. + +The reason I don't have a "trial mobile version" is that I find the +process too complex using in-app-purchases and chose not to do it to +make life simpler for me. As a substitute, I do make the full code +available for free and offer a desktop binary version free too. + +zmNinja doesn't work. Actually, even ZoneMinder web console doesn't work. You should fix this! +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Yeah, look - I understand zmNinja won't work if ZoneMinder web console +doesn't work. That being said, I really don't have time to help you +debug ZoneMinder issues. I only develop the app (zmNinja). If you can't +set up ZoneMinder properly, please post your questions in the `ZM +forum `__. You'll find more qualified +people to help you. I don't develop nor control ZoneMinder. It's a +different set of folks. Now, I'll help you, but only after you have +spent sufficient time trying your best and provide sufficient logs of +what you have done. Also remember, if you buy zmNinja, **I'm happy to +refund it anytime - just send me an email.** + +In short, I don't have the time to support ZoneMinder install issues - +sorry about that + +zmNinja doesn't work. Zoneminder works, but I have no idea why APIs don't work. You should fix this! +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +*Sigh*. I don't maintain ZoneMinder. I only develop the app. *You* need +to make sure ZoneMinder APIs work. ZoneMinder web console doesn't use +APIs. Neither does zmView. zmNinja does. It says so in the description +of the app in the store. So feel free to fix your APIs, or ask me for a +refund. Just don't whine to me, please, if your APIs are broken. I'm +*not* going to fix them for you, especially if you act like its not your +problem. `I'm perfectly fine if you choose not to use my +app `__, which +is why I refund, anytime. + +I can't compile zmNinja, help me! +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +I put out the source code, so people who know how to compile are able to +do it themselves. I also hope this will encourage folks to PR changes +(though this has rarely happened). The problem however, is that +dependencies/libraries keep changing. I just don't have the time to help +debug. If it happens to me, I'll fix it. If it doesn't I have very +limited time to remotely debug your setup issues. I'd much appreciate if +you figured it out on your own. Feel free to create an issue after +you've tried enough, but I can't guarantee I'll spend a lot of time on +source code compile issues. + +How to report errors +~~~~~~~~~~~~~~~~~~~~ + +- I don't know why something is not working if you don't provide + sufficient inputs. Start by creating a `GitHub + issue `__ and please + fill in the template correctly. If you don't want to post debug logs + in the issue, `email `__ them + to me and mention in the issue you've emailed them (you can email by + going to logs screen and tapping on the envelope button (mobile) or + you can download logs (cloud icon, desktop version) + +- If zmNinja was working, but it stopped after you upgraded ZoneMinder + be sure to mention which version was working and which was not. In + this case, please make sure you have validated the APIs work + +- Before you create an issue, please make sure you have read the + sections on `connection + issues <#connectionauthentication-issues>`__ + and `streaming <#live-streaming-issues>`__ + issues and Step 6 of :doc:`validating-api` + +- Its often hard to infer a problem especially when its due to some + unique apache/nginx mungling you might have done but haven't told me + about it. In such cases, try and give me remote access to your ZM for + a day. Configure a limited user with just one monitor. It will save + hours of frustration (mostly on my side). Thanks + +- I have released the desktop version free - download it + `here `__. Its + always easier to debug on the desktop version - give it a try. If you + hit Shift+Cmd/Ctrl+D it brings up a debug window - it helps debugging + +- Always tell me what your ZoneMinder & zmNinja versions are + +- If your app suddenly stopped working: + + - Send me DEBUG logs of the app + - tell me what changed (got to be something. You updated the app, + you upgraded ZM) + - What exactly is not working? + +Profile information storage related +----------------------------------- + +zmNinja is not saving my information. It keeps asking me to re-enter all my data +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +I've seen this happen in two cases: \* You are running out of space. +Clean up some space and try again \* On specific Android devices, +typically running Android OS less than 6.0, some (2-3) users have +reported this issue. I still don't have a good answer. Please update to +the latest app version and send me debug logs, please + +I updated my zmNinja app and all my server settings were cleared. Why? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Sorry. I've made several releases where due to programming errors, +settings got wiped out. However, starting v1.3.021 for Android and +v1.3.025 for Android, I've introduced the facility to sync with the +cloud (Google Drive/iCloud). This is the settings option. It is enabled +by default. This means if you uninstall the app and install again, the +settings should get restored. Note that both in iOS and Android, backup +schedule is managed by the OS. You can force a backup going to settings +and forcing a backup, or wait till the OS backups (typically a few +hours/phone plugged in/not being used) + +Do also note that 1.3.027 and beyond use a new WebView called WKWebView +(because iOS deprecated the old webview). If you disabled iCloud you +will have to re-enter your settings again (only once). This may not +affect Android, but I don't know for sure. + +Connection/Authentication issues +-------------------------------- + +General tips +~~~~~~~~~~~~ + +- Disable server redirects like 302 and then try if using the mobile + app +- To make sure there are no connection issues, launch your **phone + browser** and try to reach ZoneMinder. If that doesn't work, neither + with zmNinja. Many users try to access ZoneMinder from a desktop + browser and/or on the same server it is running and forget the phone + is a different device! +- Some phones need the SSL certificate installed in the device +- Specific SSL settings can cause issues with Android or iOS +- Don't use funky/special characters in passwords - try changing it to + a complex password without funky characters and try +- Use the wizard - I've seen many examples of typos when the user + thinks they don't have a typo +- If you are using basic authentication, make sure your credentials are + correct. A good way to test is to first disable basic auth and enable + it after you are sure things work without basic auth. +- Please note zmNinja does NOT support Digest authentication. So please + don't put in digest auth info when zmNinja asks for basic + authentication +- Look at your ZM logs and zmNinja logs - they help isolate the problem + +Server Redirects +~~~~~~~~~~~~~~~~ + +If the Wizard fails to connect in the mobile app but works in the +desktop app, it may be that your server is sending redirects. +Unfortunately, the current mobile HTTP stack doesn't handle cookies with +redirects well. Till this bug is fixed by the plugin author Wizard won't +work. Note that if you are running ZM 1.32 or above, you can directly +enter your settings without using the wizard and it will work because it +will try and use the new ZM 1.32 ``login.json`` API first. + +Self signed certs +~~~~~~~~~~~~~~~~~ + +A lot of people use self-signed certs. I'd strongly recommend you use +`LetsEncrypt `__ if you can. It's free. That +being said zmNinja does support self signed certs. Make sure "Enable +Strict SSL" is off in Developer settings. You will need to restart the +app. + +SSL settings +~~~~~~~~~~~~ + +If you are getting ``SSL protocol/handshake errors`` in your logs, you +very likely have specific ssl settings enabled server side that your +device network stack does not support. Note that just because it works +with the device browser does not mean it will work with zmNinja as +zmNinja does not use the browser HTTP implementation in mobile devices. + +One use reported that a setting of ``ssl_ecdh_curve secp384r1`` in his +nginx config was resulting in zmNinja Android not being able to connect +to the server. Changing it to +``ssl_ecdh_curve secp521r1:secp384r1:prime256v1;`` worked for him. + +I'd strongly recommend you remove all special ssl settings except the +certificate and key file locations, make it work and then add the +settings back one by one and see what works/does not work. + +Everything works when I use LAN IP, but I get "not authenticated" when I use WAN IP +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +This is likely happening if you use self signed SSL certs. If you are +using self signed certificated, you should make sure the "common name" +matches the hostname (or public IP) of the server you are installing ZM +in. If not, zmNinja's SSL handshake will fail. + +If you have used 'make-ssl-cert' or a similar tool that automatically +generates the cert for you, its very likely you have certificate that +uses the 'unix hostname' of your server. That will not work. + +Assuming you are usin apache and have SSL enabled, here is how to +regenerate the certs (ubuntu specific, may need to tweak it for your +distro) + +This will create a self-signed certificate/key pair and store it in +/etc/apache2/ssl (you may have to create that directory, or store it +elsewhere) + +:: + + sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/apache2/ssl/zoneminder.key -out /etc/apache2/ssl/zoneminder.crt + +Next up, edit your apache ssl config (example +/etc/apache2/sites-available/default-ssl.conf) And add/modify the +following lines: + +:: + + SSLCertificateFile /etc/apache2/ssl/zoneminder.crt + SSLCertificateKeyFile /etc/apache2/ssl/zoneminder.key + +restart apache + +:: + + sudo service apache2 restart + +Live streaming issues +--------------------- + +Summary of Everything works, but I can't see live feed +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +*Please* be diligent in reviewing this list. You'd be surprised how many +times I've had users tell me 'they have checked this list' only to find +out later they skimmed details. + +- Please enable ``AUTH_HASH_LOGINS`` as well as set ``AUTH_RELAY`` to + "hashed" + +- You think your APIs are working, but they are really not. If you open + a browser and type in ``https://yourserver/zm/api/monitors.json`` and + you see some text on top followed by monitor data, your APIs are + *not* working. You need to search the forums and figure out how to + get rid of that text. + +- Your ZoneMinder live view from the web console doesn't work either. + If this is the case, fix ZoneMinder first. Before you say "web + console works fine", make sure you are running it from a different + computer from where ZM is running. +- The phone/computer running zmNinja does not have access to your ZM + server. For example, many people test the web console on their LAN + but test zmninja on a WAN connection +- Always try with the `free desktop + version `__ first. + Enable debug view by hitting Ctrl/Cmd+Alt+D and you can see debug + logs in the console view. I can't emphasize enough how useful this + is. +- Your ``cgi-bin`` setting in zmNinja is incorrect. Please run the + wizard. There are times when the wizard can fail. In those cases, + open up ZM web console, go to view the monitor and do an "Inspect + Source" in the browser. That will show you the cgi-bin link that you + can use in zmNinja. + +For example: + +In the above case my zmNinja cgi-bin setting is +``https://myserver:myport/zm/cgi-bin`` + +- You are using Basic Authentication. See + `here <#i-can-t-see-streams-i-use-basic-auth>`__ +- You have 'multi-server' configuration enabled and you have done it + wrong. Go to ZM Web Console->Options->Servers - if you see any + entries there and you don't know what multi-server is, or you don't + use it, please disable multi-server +- When trying to view live images, look at your *webserver* error logs + - example Apache's ``error.log`` - see any image/jpg errors? That + means you are missing libraries +- You have set up a multi-server install of ZM without knowing you did + See `here <#i-can-t-see-streams-multi-server-is-enabled>`__ +- Look at zmNinja, ZoneMinder and web server error logs at the time of + error - one of them should give more clues. Please send me *all* the + logs if you ask for help +- Read the set of notes below + +General note +~~~~~~~~~~~~ + +To debug streaming notes, always try with the free desktop version +first. When trying to stream simultaneously look at the debug logs of +zmNinja (``Ctrl/Cmd+Alt+D`` in desktop build, console and/or network +tab) and your webserver error logs. + +I can't see stream: And I can't see streams in ZoneMinder webconsole either +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Check if streaming works in the web interface. If it does not work, +zmNinja won't work either. Fix ZM first + +I can't see streams: I use basic auth +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Starting Chrome v59, the browser changed basic credential behavior. The +issue report is +`here `__. +Here is the core issue: zmNinja constructs URLs as +``http://user:password@server`` when you have basic auth (and starting +v1.3 uses the ``Authorization`` header). However, since images are +rendered using ```` there is no option but to put in a +``user:password`` in the URL. Chrome allows this format for direct +requests (such as API calls) but will strip out the ``user:password`` +part for *embedded* requests (like ```` tags inside a page). +So what happens is your APIs work, but you won't see images. There is a +reason why Chrome does this - its bad to pass on a user :password in a +URL as its clear text (even if you are on HTTPS, as its in the URL). As +I said earlier, The *right* way to do this is to replace the +``user:pass`` with an ``Authorization`` header but there is no way to do +that with images that are rendered with ```` (There are several +plugins that attempt to do this, but don't work with streaming MJPEG +images). Bottom line, this is a problem for apps like zmNinja and it +affects you. + +How this affects you: \* If you are using HTTP Basic Authentication + +Then your images won't show. + +Possible Workarounds: \* Configure your web server to skip basic +authentication for ``nph-zms`` URLs \* If you are using a ReverseProxy, +you can insert the authorization header inside the apache proxy \* +Disable HTTP Basic auth for now \* Downgrade Chrome + +Skipping auth for ``nph-zms`` URLs +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Here is what I've used that works with basic-auth. This requires a basic +auth portal login and once logged in allows skipping of image URLs (the +idea comes from `Adam Outler `__ - he +uses a different approach using reverse proxies, which I link to later) + +.. code:: apache + + # this configuration assumes your server portal is server:port/zm + # and cgi-path is /zm/cgi-bin. Please change it to your specific environment + # Also requires Apache 2.4 or above + + + SetEnvIf Request_URI ^/zm/cgi-bin/ noauth=1 + SetEnvIf Request_URI ^/zm/index.php noauth=1 + AuthType Basic + AuthName "Auth Required" + AuthUserFile "/etc/apache2/.htpasswd" + + Require valid-user + Require env noauth + + + +Authorization with a ReverseProxy +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Simple starter +'''''''''''''' + +**STEP 1**: Enable "Append basic auth tokens in images" option in +zmNinja->Developer Settings and save. What this does is that image URLs +will append a "basicauth" token parameter with your basic authentication +credentials. This token can then be parsed by Apache and inserted as a +valid Authorization header. Don't enable this option if you are not +using HTTPS because the request-URI will be transmitted without +encryption and it will contain your basic auth credentials, encoded in +base64, which is trivial to decode. + +**STEP 2 (Apache)**: Use mod\_rewrite and mod\_header to convert the +token into an authorization in your Apache config. Add this to the +relevant section (``VirtualHost`` or others) + +.. code:: apache + + RewriteEngine on + RewriteCond %{QUERY_STRING} (?:^|&)basicauth=([^&]+) + RewriteRule (.*) - [E=QS_TOKEN:%1] + RequestHeader set Authorization "Basic %{QS_TOKEN}e" env=QS_TOKEN + +**STEP 2 (Nginx)**: Thanks to user [@ysammy](https://github.com/ysammy) + +.. code:: nginx + + location /zm/cgi-bin/nph-zms { + proxy_pass http://:/zm/cgi-bin/nph-zms; + proxy_set_header Authorization "Basic $arg_basicauth"; + } + +A more complete and more secure option +'''''''''''''''''''''''''''''''''''''' + +User `Adam Outler `__ has contributed the +following process: see +`HERE `__. +Adam also has this to say about why proxies should be recommended for +HTTPS enabled ZoneMinder instances: + + A proxy server should be on the list of recommendations for + Zoneminder. HTTPS requires processing to encrypt and decrypt. This + takes processor cycles away from Zoneminder's recording. Since HTTPS + is now basically a requirement, there should be a page dedicated to + proxy, https, auth, and their nuances. I just picked up 2-4K cameras + and processing suddenly became an issue :). + +I can't see streams: Multi-server is enabled +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The chances are very high that you have enabled ZoneMinder's +`Multi-Server `__ +option and you entered something like ``localhost`` in server settings. +**DON'T. You can't enter localhost**. If you are not using multi-server, +remove any server settings. If you are using multi-server, you need to +put in a valid server IP or hostname, not ``localhost``. BTW, if you did +put in ``localhost`` you will note that your ZM web console also won't +work if you try to launch your browser on a different machine from where +ZM is running. + +I can't see streams: you have cgi-bin issues +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +- Try to use the wizard. If it fails, +- Go to zmNinja settings and fix your cgi-bin path. the automatic path + that is filled in won't work. Here is a hint, go to + zoneminder->options->paths and check the value of the cgi-bin path - + your zmNinja path will be "base path of your server" + cgi-bin path. + +zmNinja montage does not seem smooth - feeds seem a little delayed compared to ZM console +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +zmNinja does not use ``nph-zms`` to display live feeds in montage. This +is because Chrome only allows a maximum of 6 connections per (sub)domain +which means you can't have more than 6 active TCP connections to a +single domain at the same time. This also means that you can't display +more than 6 monitors together. To avoid this, I use the zoneminder +"snapshot" feature that displays a still from the monitor and then +refresh it every X seconds (by default X=2 unless you switch to low +bandwidth mode. You can change X in developer settings) + +That being said, starting v1.3.0 of zmNinja onwards, I now support +multi-port (available in ZM 1.32 onwards) that lets you stream as many +monitors as you need. Read +`this `__ +post for more details. + +Event images/streaming related +------------------------------ + +General note +~~~~~~~~~~~~ + +To debug streaming notes, always try with the free desktop version +first. When trying to stream simultaneously look at the debug logs of +zmNinja (``Ctrl/Cmd+Alt+D`` in desktop build, console and/or network +tab) and your webserver error logs. + +Also, Starting ZM 1.32 and beyond, please enable ``AUTH_HASH_LOGINS`` as +well as set ``AUTH_RELAY`` to "hashed" + +Event stream viewing does not work +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +- Look at apache error logs - it often gives you hints + +Video Not Playable +~~~~~~~~~~~~~~~~~~ + +- Mobile devices have more restrictions to video playback than + destkops. Make sure you first check if the video is playable in + Chrome using the same phone you are using zmNinja on +- There could be other reasons due to which the video is not playable: +- There is an encoding issue in the video generated +- The video resolution is too big (see `this + thread `__) +- In general, to get to the root of what is going on, you'll need + device logs using ADB (see + `this `__) + +Event thumbnails/images don't show +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Starting zmNinja 1.3.26 and beyond, if you are using OPT\_AUTH you need +to enable AUTH\_HASH\_LOGINS or you won't be able to see image snapshots +and thumbnails. Only applicable for mobiles. + +When viewing individual frames, some event frames show, but some don't +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +This can happen if you are using Video Storage (Passthru or X264 Encode) +and have disabled frame (JPEG) storage completely. What happens is +ZoneMinder uses ``ffmpeg`` to extract frames from timestamps and +sometimes it is unable to extract a frame for a specific timestamp, +resulting in this issue. If you see HTTP 404 messages for some frames, +but the video plays fine, then this is why. + +zmNinja montage screen shows all my monitors, but in Event Montage, I only see 5? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +You are likely using Chrome (Android or desktop version). Chrome allows +a total of 6 simultaneous connections to a domain/sub-domain. ZoneMinder +uses a long running TCP stream for each monitor display (keeps sending +jpeg images). This means you can only display 6 streams at a time in +Chrome. I work around this problem by *not* asking for live streams in +montages - I ask for 'snapshots' and keep refreshing snapshots every 2 +seconds. This makes montage display non-realtime, but scales to as many +monitors you have. In Event Montage however, I am using zms to display +long running streams - trying to do snapshots in event montage is a lot +of work and I need to keep track of when the event ends, move to next +image etc. I limit this to 5 because I need 1 for control messages. + +Other misc. issues +------------------ + +I suddently see an error message saying I need to enable ZM\_AUTH\_HASH\_LOGINS. This wasn't there before +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Yes. Starting 1.3.027 onwards, due to a new UI web rendering engine that +enforces CORS, I've had to change my strategy on how network calls are +made. Briefly, on mobile devices, I now use a native HTTP stack and not +the browser HTTP stack. However, images are rendered using the browser +HTTP stack which causes this message. In short, you need to enable it, +and restart ZM. + +zmNinja 1.2.515 and beyond says "Need API Upgrade" for the 24hr review feature. What does that mean? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +You need to update an API file in Zoneminder server. ZoneMinder folks +haven't yet (as of Apr 2018) made a release with that API change. To do +it manually,simply replace your ``EventsController.php`` (typically in +``/usr/share/zoneminder/www/api/app/Controller``) with `this +one `__. + +I upgraded ZoneMinder to 1.30.2 or above and zmNinja stopped working! +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +ZoneMinder changed API packaging with ZM 1.30.2 and above. You will have +to read your distro notes on how to **properly** update. Read +`this `__ +thread. Before you think zmNinja is the problem, make sure your APIs +are working (see :doc:`validating-api`) + +Summary of reasons why zmNinja might have stopped working: - You did not +check if your APIs are working after the upgrade - You did not upgrade +properly (just updating the ZM package without following distro +instructions with ZM is not sufficient) - You are missing some key +CakePHP modules, likely ``php5-apc`` which would have been installed if +you read all the package instructions. You can install it manually - You +might need to restart your system after upgrading (properly) + +I am running ZM on a custom port. zmNinja is unable to reach my ZoneMinder server but I tried on a regular browser (Firefox/Opera/IE) and it I can reach it +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +zmNinja on Android and Desktops uses an embedded chrome browser. Chrome +marks certain ports as "unsafe" and won't allow connections to go out. +The list of ports to avoid are +`here `__ + +The Montage screen is causing issues with my ZM server - I get connection timeout issues or MySQL connection problems +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +- zmNinja uses a different approach to display montage than ZoneMinder. + In zmNinja montage screen, I display a snapshot of each monitor and + refresh it every few seconds. This results in many short TCP + connections constantly being opened and closed. The reason I have to + do this is Chrome only allows 6 connections to a domain, which means + if I don't keep terminating TCP connections, I won't be able to show + more than 6 monitors. Each time I open a new TCP connection for a + snapshot, the ZM backend invokes mySQL to authenticate the request. + You will need to increase mySQL ``max_connections`` in ``my.cnf`` if + you are facing time\_wait/timeout issues. + +The app works great - except it doesn't work on ONE Android phone - works in others! +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +zmNinja uses an embedded chrome browser in its app. If you have safe +browsing enabled, it may affect zmNinja. However, if you are facing this +problem, its likely you can't access ZM from a mobile web browser +either. The problem that might be occurring is that zmNinja is trying to +reach your ZM server and your settings prohibit it from reaching ZM, so +it fails. See +`this `__ +discussion + +APIs are not working ! ZM console works fine. +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +:doc:`validating-api` + +I'm using mocord/record and I don't see events without alarms +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Tap on the "..." menu option and toggle "Show all events". By default, +it shows events with at least one alarm frame + +Taking snapshots or downloading videos don't work in Android +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +If you are unable to download/save, look at your logs. If you see +something like +``"exception":"java.security.cert.CertPathValidatorException: Trust anchor for certification path not found."`` +, chances are you are using self-signed certs. You need to install the +certificate on your phone. Installing is as easy as emailing yourself +the ".crt" file and tapping on it from your device to install it. In +general, both Apple and Google have been incrementally tightening rules +for self signed certificates - they generally discourage usage of such +certs and over time both Chrome (Android) and WkWebView (iOS) have added +new restrictions/checks which affects usage. + +Pan/Tilt/Zoom doesn't work +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Tilt/Zoom/Presets support has not been added. But for this to work, PTZ +needs to work in ZM first. Once it works in ZM, try it in ZMNinja. Also +note that you may need to disable CSRF in your Options in ZoneMinder - +it seems to cause all sorts of issues. + +What is this Event Server? +-------------------------- + +The Event Server is a contribution I made to ZoneMinder that adds a +daemon to the existing list. It listens for new events using shared +memory (aka very efficient) and then sends notifications of events to +listeners (you can write your own app that listen as well as use +zmNinja). This is a chapter on its own, and I have a dedicated +page/project for this +`here `__. I'd encourage +you to install and use it - its very nice. + +It looks like you allow me to modify the frequency of push notifications. Very cool - will it send me all events that I missed if I make the frequency of a monitor event push to say, 600 seconds? +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Nope. It only sends the latest events. What it does is before sending +push notifications, it checks if the last time a push was sent for this +monitor is < the time you specified. If it is, it does not send. That's +all. + +Is zmNinja free? +---------------- + +The source code is free, grab it, compile it, use it. The desktop ports +are free as of today.

+**DON'T** contact me first, as its not a zmNinja bug)
+
+.. code:: jsonld
+
+    {"events":[{"Event":{ /* many more details */ }}]}
+
+*Top reasons why monitors and events API returns blank while getVersion
+works:* \* You don't have monitor/event view permissions allocated to
+the user \* You have an invalid camera definition (happens sometimes
+when you remove and re-add cameras) \* If you are using non UTF8
+characters in your monitor names/zone names this can cause issues. Edit
+``/usr/share/zoneminder/www/api/app/Config/database.php`` (assuming ZM
+is in /usr/share) and make sure ``'encoding' => 'utf8'`` is
+*uncommented* (remove ``//``) around line 74. I've submitted a
+`patch `__
+but till its merged, you might have to do it manually.
+
+zmNinja API notes:
+^^^^^^^^^^^^^^^^^^
+
+-  Please make sure the user credentials you use has:
+-  view or edit access to monitors
+-  view or edit access to streams
+-  view or edit access to system
+
+-  If you are accessing zmNinja remotely, make sure you first access ZM
+   remotely from your desktop browser, ensure it works and then use the
+   same DNS/IP for zmNinja
