This camera would not work with my $1,200 Security Camera King DVR. I tried tech support, and they were great, and tried many things, but alas. They were not able to get this unit to work with my DVR. Tech support also recommended against using it as a standalone, which it claims it can do on an SD card.
I ended up getting one of the mini recorders, just to be able to use this camera. After setting it up on the new DVR, it does work, however, if you try to zoom in, the range of focus does not support it. The focus knob gets tight before it will focus, so I ended up using it at a mid zoom range when I had bought it for the long distance zoom capability..
Lastly, my experience with it at night is dismal. The IR from this camera shows up well on other cameras, but unless the camera has some form of daylight, I get a completely black image It goes monochrome at dusk, them just black (no picture)..
It does have a crazy number of wires on the pigtail and reportedly can do many things. However for me, it does not work for long range zoom pictures as hoped, or at night, which makes it mildly useless.
I have fixed focal length cameras that cost much less than what this one did, that perform MUCH better.
Some people seem to have had better luck with this camera, however, I would recommend against purchasing this one.
