EX Series - Common Questions » Hardware Issues

I'm experiencing random camera feeds that "freeze" and/or stop recording without reason... sometimes the entire system locks! Why?

There are a number of possibilities for this extremely rare occurence, but the most likely cause is camera input signal failure. This is where the signal coming into a DVR from a camera is somehow distorted or otherwise compromised.

First, check to ensure that the camera cable and connectors are solid and properly made. Second, check the camera itself - and the camera power supply - to ensure that there is no fault with the unit or the local wiring. Temporarily swap out the suspect camera and wiring with a known good unit and cable and re-test.

Next, if the camera is not the problem, then check to make sure the DVR board is properly seated (plugged) into the PCI slot. Check the board itself to ensure there are no loose connectors or unsoldered wiring.

After that, check the "pigtail" connector cable. This can be a source of issues if the connector has suffered damage due to too much cable weight stressing the small individual camera wires. Swap it out with a known good connector and re-test.

Finally, check the computer hardware and operating system. This means test the RAM, the Hard Drive(s) and even the video card, the mainboard and the computer power supply. And, if absolutely necessary wipe Windows and re-install the whole system and drivers from scratch.
