Ensure the HDMI cable is connected from the recorder to your TV/Monitor. Ensure you are tuned to the right HDMI input if your TV/Monitor has more than one. Try replacing the HDMI cable, to see if you have a faulty cable. Try connecting the recorder to another HDMI input or a 2nd TV/Monitor.

My cameras were cut on my night owl so on the camera side there is 3 small wires which are green red and white and there is also a grey which is thicker strip back the grey and you'll find a yellow wire those under the grey cover will go spliced into the big white wire on the connector side that goes to your dvr and the wire between the grey and yellow needs to splice onto the outside wire that's between the black cover and white wire on the dvr side also on the dvr wire there will be a red and black wire connect the red wire to the three small wires on the camera and it should work I did not use the black wire because I couldn't find where it connects I have a night owl series vdp2

Same here. Updated firmware system rebooted and locked on the Night Owl screen. Mine is the FS-8500.( DVR model FS-500 ). Anybody find a fix to the issue? I believe the firmware is in the motherboard. Anyway to hook to PC and "push / force" the firmware into the DVR. Or some tyoe of master reset. Or is this thing bricked for good.

If it cant be fixed, do you know where I can get a new motherboard with firmware installed. Tried talking to tech support but am fighting with them over the issue. Pretty freaking useless over there.

Call their help desk they say is the only way..

Your problem is not a problem. DVR is programmed to record if he sees movement. Cancel this job and it will not be delayed or freezing. This is from software.

If your DVR is networked you can use this utility to recover the passwords
