Araxis: Further info

Android devices can be used as network cameras. There are various apps for Android that can provide a video stream, and some that record videos which can be imported into a surveillance system. It should also be possible, by rooting your device, to use existing linux programs to stream camera video.

== Apps ==
It is recommended to use apps from a trusted source. Some apps will serve ads, others will pull your personal information. Choose wisely.

'''F-Droid'''

Provides a repository of free and open source software for android.
[https://f-droid.org/]

'''Wifi Camera'''

Supports Mjpeg and audio streaming. Built-in web service to see the video via browser on a PC.

Version 1.61
JPEG images are available at http://<ipaddress>:8080/stream/live.jpg
ZM does not seem to work at pulling the images directly.
Pull the files via a script populate them in a local directory and you can get 1FPS in ZM.

Command:

*$ watch --interval .2 "wget -q http://<ipaddress>:8080/stream/live.jpg -o /dir/you/want/to/put/image/download.jpg && mv /dir/you/want/to/put/image/download.jpg /dir/you/want/to/put/image/live.jpg"

*ZM Settings:
*Type: File
*Maximum FPS: 5
*Address: /dir/you/want/to/put/image/live.jpg

Not sure why ZM doesn't display frames faster than 1 FPS when the files are clearly updating faster.
You move the file so that there are not incomplete files due to wget overwriting the previous file.

'''Spydroid'''

Provides HTTP webpage and RTSP stream. RTSP stream is accessible from rtsp://<ipaddressofphone>:8086
Stream is viewable in VLC and recordable through VLC, but as of yet is not viewable in ZM.

Settings

*RTSP Server: enabled

Then stream from VLC.

'''Mobile WebCam'''

This application provides an MJPEG stream, from its web server. Does not work on all devices. This applications is designed to be used for occasional snapshots (hence the name 'webcam') and is not designed by the author as an IP Camera application. However it should be possible to get very low FPS with this application such as .2 FPS) into Zoneminder.

''Settings''

*Upload: SD Card (no sdcard needed)
*Refresh Time: 5
*Operation Mode: Background
*Remote Control - Web Browser Access - http://<ipaddress>:8080 : click line. Choose enable for bluetooth (can disable later)
*Shutter Sound: Disabled

Web page is viewable at: http://<ipaddress>:8080
There is an MJPEG stream link near the bottom half of the screen.
This stream should be accessible by ZM.

'''CosyDVR'''

This application records Video to a SD card. Intended to be used as a alternative to Dashcams. You can grab the videos off of the android through ADB or a rooted device. Old videos can be automatically deleted. It is unknown whether videos can be imported into ZM.

== Rooting ==
By rooting your device you can gain access to full linux arm repositories. It should be possible to stream the camera with popular and well known programs.

'''Lil' Debi'''

Gives access to debian repositories.

'''MJPEG-Streamer'''

Used on Single Board Computers (such as Beaglebone) for webcam Mjpeg streaming.

MJPEG vs H264

2016-02-21T00:53:32Z

Araxis: Page creation

For small systems, cameras that provide H264 stream, or an MJPEG stream will work well. If you are scaling to a large system with many cameras, you will notice that ZM uses more resources to decode H264 video (through FFMPEG or VLC) than a comparable MJPEG camera which provides a JPEG stream or image.

Hardware Compatibility List

2016-02-21T00:39:09Z

Araxis: /* Network Cameras */ Android

Zoneminder will work with almost any capture card that is supported by the linux kernel. You may find additional details about supported hardware in the part of the forums. Also if you find something in the forums that is missing from the wiki ADD IT.

== Capture Cards ==

[[Anykeeper]]

[[Avermedia]]

[[Camsecure PCI Express video capture]]

[[WinFast TV2000 XP]]

[[Rapid OS]]

[[KesCom PG104]]

[[IEI Technology Corp. IVC-268G-R20]]

== bt8x8 Cards ==
A note on the bt8x8-based TV-tuner cards: these usually have beside the tuner input, also a Composite and an S-Video input. You can hook up 2 analog cameras to these, and access from ZoneMinder both of them as individual cameras, at max 15Fps. You don't need two separate TV cards for two cameras!

[[Pico2000]] - 4 port card, one chip bt878, around 2 fps when using all channels

[[Bt878_4chip_8inputs]] -4 chips bt878, 8 inputs, around 5 fps when using 2 inputs per chip

[[:Image:Karta.jpg| bt878 8 chip 8 input]] - This card is supplied with D-sub to 8 BNC connector and uses the bt878 chip for each input allowing full frame rates and quality. See [[Kodicom 8800]] for more information.

Geovision GV250 bt878a single chip 4 inputs - This capture Card is supplied with 4 video inputs but with NO audio channel

'''Most other BTTV (bt878, bt848) cards, see /usr/src/linux/Documentation/video4linux/bttv/CARDLIST on your system for a list of some of them.'''

== Analog Cameras ==

Any regular composite or S-video camera connected via a supported capture card. Some analog cameras feature camera control - ZM supports several of these camera's Pan/Tilt/Zoom functions via serial port control, as well as camera Presets, Focus, Iris, etc.
*[[PicturetelControlScript | PictureTel PTZ2N]].

== Network Cameras ==
For Network Cams to work they need to be able to stream MJPEG without the requirement of activex controls. If you see the requirement for the camera calls for IE then there is a good chance it may not work. The other option is to grab JPEG images if the camera supports that option which will work but at a lower frame rate.

Any network camera that allows access to single JPEG image grabs or '''some but not all''' multi-part JPEG feeds.

== Network Digitizers ==

Like Network Cameras, these devices produce a video stream - but they accept an analog video input from a camera or other video source.

* [[Synectics E100]] encoder
*The [[IP9100 | Aviosys IP9100, Models A, B and Plus]] has four analog video inputs. It produces a ZM compatible video stream from one of the inputs, which is selectable via an HTTP GET command. There might even be a control script for ZM that lets you select the active video input using ''ZM's Camera Control Presets!''

With the yoics Aviosys 9100 firmware at http://www.yoics.com/?p=28, ZoneMinder can directly access all four ports via /usr/yoicsX.jpg as the remote host path, where X is 0 - 3.

* [[Bosch VIP X1 Single-channel]] video encoder [http://products.boschsecuritysystems.eu/en/EMEA/products/bxp/SKU15449253232961378955-CATMda7ec5dc0edf5b1a0b8cb619e2e11308]

* Video cameras & safes for antitheft purpose on the website http://www.infosafe.fr

== USB Cameras ==

*Just Zoom USB cam

*Creative Webcam Pro, Webcam 3, LIVE! Cam OPTIA PRO (V4L2, Chan 0, PAL, YUYV)

*''Most'' UVCvideo cameras, including: Advent AWC213, Creative Labs VF0420, [[Logitech QuickCam Express]], Logitech HD C270, QuickCam Pro 3000, [[QuickCam Pro 4000]], QuickCam Communicate STX/Deluxe, [[Logitech Webcam Pro 9000]], and [[Webcam C250]]

*Logitech Quickcam Orbit/Sphere (experimental basic pan/tilt control has also published for testing and hacking [http://www.zoneminder.com/forums/viewtopic.php?t=9788])

*[[Philips]]

*Any OV511 based USB camera [http://alpha.dyndns.org/ov511/cameras.html]

*Any CPIA based USB camera [http://webcam.sourceforge.net]

*[[LabTec WebCam Pro]]

*Confirmed basic functionality with Microsoft Lifecam VX 5000 using UVC Streaming method

Note that most USB cameras that can use Video4Linux/V4L2, and so can be used by ZoneMinder. Some have older chipsets and can be hard to find new.

Note that PWC drivers are not included in the kernel. Some distribution's add them in and other may not. Here are some relevant links:
* [http://www.smcc.demon.nl/webcam/ Old Maintainer]
* [http://www.saillard.org/linux/pwc/ Current PWC Maintainer]

== X10 Devices ==
The only device that really needs to be compatable with ZM is the Transceiver, all other x10 devices comunicate through that device.

== All other hardware as supported by Linux ==
To find out if your hardware is supported, check the [http://www.zoneminder.com/forums/viewforum.php?f=10 HCL]

== Plug Computers ==
Guruplug Server Plus -> How to install Zoneminder

== Raspberry Pi - Raspbian ==

ZM 1.25 is already in Raspbian. Newer development packages are available.

You will want libjpeg-turbo from the following repository by adding to your /etc/apt/sources.list

deb http://zarrenspry.info/repos/apt/raspbian testing main
deb-src http://zarrenspry.info/repos/apt/raspbian testing main

Add gpg by

wget -O - http://zarrenspry.info/zarrenspry.gpg.key|apt-key add -

apt-get install libturbojpeg8 libturbojpeg8-dev

If using the Pi camera, you will need to enable it in raspi-config as well as loading the v4l2 kernel module by adding the following to your /etc/modules

bcm2835-v4l2

Although the camera will can capture high res, you don't have enough RAM currently to do so. Especially if you have the early 256MB model. So ust stick to 640x480.

You should be able to get around 20fps, but if you do anything involving the CPU you will get underruns.

== Raspberry Pi 2 - Fedora ==

The latest version of ZoneMinder is available for the Raspberry Pi 2 when running Fedora.

Araxis: MJPEG Stream issues

Check also informations made for [[Foscam_FI9805W]]

Support only Windows while configuring - camera software need plugin which is provided as exe installer.

:System Firmware Version 1.5.1.11
:Application Firmware Version 2.22.1.143

Currently i am using this camera settings:
<pre>
Off Enhanced Vision (it always slow down when IR ON to 5fps)
User-defined
Resolution 720P
Bit Rate 4M
Frame rate 15
Key Frame Interval 10
Variable bitrate Yes
</pre>

And Zoneminder settings:
<pre>
Source type: FFmpeg
Source: rtsp://[LOGIN]:[PASSWORD]@10.0.0.11:88/videoMain
Remote method: RTP/RTSP
Capture width: 800
Capture height: 450
</pre>

I think 720P resolution for this camera is interpolated, so i decided to decrease capture width & height to 800x450.

If you dont care about image size (and quality...) use capture width/height 1280 / 720.

'''Differences between FI9805W'''

Issues with RTSP stream also is here.
There is no option 920P for this camera, use 720P while configuring via camera menu.

'''MJPEG Stream issues'''

There seems to be issues with camera and MJPEG stream. It is not able to handle much motion before dropping out. VLC is able to keep a steady stream regardless of motion. Some video settings can be changed to improve but not fix stream dropping out (9803P).

'''Commands'''

# Rebooting VIA Command line
<pre>
http://[CAMERA_IP]:[CAMERA_PORT]/cgi-bin/CGIProxy.fcgi?cmd=rebootSystem&usr=[USERNAME]&pwd=[PASSWORD]
</pre>
RTSP stream can hang, but API will still work fine.
You can reboot camera by using URL provided above.

2. Modify first five params to fit Your needs, and save file

3. Make it executable
<pre>
# chmod +x /bin/foscam_restarter.php
</pre>

4. OPTIONAL You can check if its working properly with (it will restart your camera!!)
<pre>
# foscam_restarter.php force
</pre>

5. Make log file for restarter
<pre>
# touch /var/log/foscam_restarter.log
</pre>

6. Add script to crontab
<pre>
# echo "*/1 * * * * root /bin/foscam_restarter.php >> /var/log/foscam_restarter.log" > /etc/cron.d/foscam_restarter
# echo "" >> /etc/cron.d/foscam_restarter
</pre>

7. Restart cron
<pre>
# service cron restart
</pre>

8. If You have logrotate on zoneminder logs, modify logrotate script - add cleanup of /tmp/foscam_restarter/info_file (defined as INFO_FILE)
For example, script for logrotate with restarter support:
<pre>
/var/log/zm/*.log {
daily
missingok
rotate 31
compress
delaycompress
sharedscripts
postrotate
/usr/bin/zmpkg.pl logrot 2> /dev/null > /dev/null || true
/bin/rm -f /tmp/foscam_restarter/info_file
endscript
}
</pre>

9. Probably its done, unless You have other custom modifications.

or

rtsp://IPADDRESS//user=admin_password=UO8XjMJE_channel=1_stream=0.sdp

Although the password may be different. Onvif will give you the path of the above.
Works in VLC and FFMPEG. Requires only one device to be accessing the stream at a time.
If you try to access the above stream in ZM while VLC is streaming it, it won't work.
