What I check is the camera is getting video to the BNC ends by plugging each one into a monitor. Some folk don't have the monitor and can't test their setup. If so you have to decide if you need to call in a tech to sort it out.
Also, most of those cards have settings for NTSC, PAL and more. I am not offering to detail all the settings. You as the CCTV system builder have to know this area.
Hello. The other day I installed a Lorex QLR460 card on computer, and ran my existing cameras to it. (Toshiba CCD IK-645A. With Honeywell HLD5v50F13L auto Iris lens) The software opens fine and it sees there are cameras attached to it, but it does not give me a live feed of the cameras like it is supposed to.I have successfully connected the 4 Cameras I have to a tv with only an adapter so I know that they work and they have power. any advice on how to fix or test this setup? I have tried to contact Lorex several times over the last 2-3 weeks with no help at all. Any help would be GREATLY appreciated.
