For $43 (delivered) I recently purchased a small, outdoor 720P ONVIF camera from China via eBay. It took a little over a month to arrive, but it did arrive. See attached screen capture of its eBay listing page. It is quite small - the camera body measures 3.75x2.75x2.75 inches. The image quality is quite nice - see the attachment.
It, like most Chinese IP-Cameras is MicroSoft Internet Explorer (IE) centric, meaning that full utility is achieved only by using IE with the camera's downloaded ActiveX installed. While I did test the camera in a Windows XP VirtualBox, I use Linux, not Microsoft products. Consequentially, this camera is sub-par for non-Microsoft use. Nonetheless, it is useful. I mostly monitor my cameras on either my Android phone or tablet and I can configure it for good operation on Android. On the Android, my preferred app is "IP Cam Viewer" by Robert Chou. It is excellent for my MJPEG and pretty good for ONVIF cameras. The other Android app that I use is just for ONVIF cameras - "Onvifer" by IPCentcom. Its image quality for ONVIF is excellent. On my desktop, I use VLC for image viewing.
The camera that I received has a wide-angle 3.6mm lens. I think that I would prefer the 6mm or 8mm as there is some edge distortion with the 3.6mm lens.
The camera's factory is Shenzhen Hong Jing Tian Electronics. The manufacturer is listed as "IPCAM" and the model as "C6F0SeZ3N0P0L0". The WiFI card identifies itself as Shenzen Oqemray Technology. The Shenzen Oqemray Technology website only lists peripherals like WiFi cards on their website.
The IP address arrives fixed at "192.168.1.88", although DHCP can be activated, if desired.
The eBay seller that I used is affiliated with the factory. The seller's eBay name is "szhongjingtian". In an email, szhongjingtian signed her name as an employee of Shenzhen HONGJINGTIAN Electronics Co., Ltd.
FYI - this is how I access via RTSP:
rtsp://myURL/11 (Note 11 is HD & 12 is SD)
If you use Windows OS you can utilize the software that comes with the camera.
NOTE: The PDF file at the link below is for a camera with the same camera PCB. All CGI commands from it that I have tried also work with this camera:
Just a thought, and maybe I'm off track but in looking at the library source for the Open Source project "ONVIF Device Manager" I see that the authors are using uses ffmpeg for media decoding.
Please post your progress.
... I got no idea what Foscam firmware/web UI versions are compatible with it !...
Answer, none. The WebUI would probably work but possibly not all functions - ditti for the kernel although it is more dubious and romfs is VERY unlikely to work. Subtle hardware differences, especially around the sensor makes cross-brand compatibility virtually nil.
You can even turn the tl-wr703n into a camera using firmware packages found at the Madox.net blog.
The comm_write.cgi command sends a string out the serial console. You must open up the camera and connect to the serial console within. Once connected correctly you can bring the 3 wires out of the camera and connect to your Arduino. Be aware that the Arduino is a 5V device and the camera is a 3.3V device so the Arduino's TX line will need diode isolation and a pullup resistor to 3.3V to avoid damaging the camera.
Read the wiki on this site HERE and HERE for some help on connecting. There are also many posts on the topic of serial connection such as HERE. There also good instructions HERE. There is info on diode isolation of the 5V Arduino from the 3.3V camera HERE.
Good luck and be sure to share your results.
P.S.: When I experimented with the comm_write.cgi command, the serial sent out some error message but, IMPORTANTLY, it also sent out the text sent in the comm_write.cgi command, enabling your Arduino to monitor and react to the cammand.
Pins 1 and 2 are controlled by a DC 5V relay. If you click on the chain icon in the operator device control, the normally open contacts of pins 1 and 2 will close until you click on the break-chain icon. If “I/O Linkage on Alarm” is set, Pins 1&2 will close upon a short of pins 3&4, and remain closed until reset by click on the break-chain icon.
The current limits for this relay connected between I/O Alarm pins 1 & 2 are a Maximum current of 2A/24VDC, 2A/125VAC.
When you consider reliability recall the Mean Time Between Failure formula [MTBF = 1/(sum of all the part failure rates)]. The more parts/complexity, the more often there is a failure.
Consider a mature proven product with a good track record that meets your needs. I personally don't value the IR-CUT feature as it adds a lot of complexity just so that daytime colors will be more true. I don't care if trees are not true green so long as I can see the objects or movement that are of interest to me.
