I have the same (?) camera, at least by the outside looks, bought here:
http://www.ebay.com/itm/CCTV-IR-1080X720P-1-0MP-HD-P2P-outdoor-3-6mm-Onvif-network-Security-IP-Camera-/111245655784?pt=US_Security_Cameras&hash=item19e6c1fee8My camera is labelled as: Vanxse Model V-B811, but I've seen many variants, as far a Vendor and Model numbers go, on different reseller sites.
I lost access to web interface on port 80, nmap scan shows only ports: 21 (ftp), 23 (telnet) and 5050 (multimedia conference control tool) open on the camera. Can't access with Telnet, wrong username and/or password, but I was able to pull some files with FTP. There were the two directories listed, "/conf" and "/custom" (can send via PM), which do not mean a whole lot to me. Poked around some of the ".html" files, but did not find anything of use. Seems like most of the configuration is saved in ".json" files.
The reseller did not provide any files or directions upon request (get what you pay for...)
Camera goes apart fairly easily, just carefully unscrew the body (threads are under the ring), paying attention not to mess up the wiring inside.
This is what is printed on the board: Hi3518_OV9712_v2.2.3_SQ38, which tells me it has a Hi3518 chip with OV9712 CMOS, version 2.2.3 (?) and whatever SQ38 is...
Will post some pictures of the board later on today...
Hope to get some more good info sharing going on here.
