Hello everyone, I just ordered a ZOSI 8 channel BNC Analog DVR (Model name: ZR08VM) for my 8 analog cameras, and managed to find the RTSP streams! The RTSP stream is located at rtsp://192.168.x.x/video9 of course replacing the IP address with your DVR's IP. (May appear as Ansjer Electronics on your router's device list or an nmap scan) For some reason the channel numbers start at 9, so for me channel 1 was found at URL ending with video9, channel 2 at URL ending with video10 and so on. It also seems there's no security, so even if you setup a password on the box, the rtsp stream can be accessed without it. For that reason, I would recommend using a server to act as a firewall between the box and the internet, so that the streams are never directly exposed to the network without authentication. On this model only port 554 (RTSP) was open, and after many hours of toying with nmap I started just trying common RTSP URLs suggested online. I noticed that most of the time the connection would close immediately, but when I tried rtsp://192.168.x.x/video1 it simply got stuck trying to connect, but didn't close instantly. I figured this was a good sign, and tried different changing that last number until I found the correct range (9-16) which may be different for you depending on the model. Since BNC PCIe cards are expensive (and for security reasons), I wanted to just use this DVR solely for its BNC ports to feed the streams to my home server where I'll actually manage the cameras. Thankfully, I can now do that easily with RTSP while bypassing the crappy firmware on the box!
