I'm very new to video security and I'm having an issue with the first installation I did. I'm a Video-Insight reseller and we installed an analog server with 18 color cameras a while back. The system has been running fine minus a few minor issues up until about 2 weeks ago. One camera started having reset errors and signal droppage, so I was called out to investigate. Over the course of the last 2 weeks I've been in contact with V-I and replaced both the Dongel and the physical VJ120 capture card on RMA. I've reinstalled the software/drivers/WMVDLL's and the like to no avail. The problem just keeps getting worse now. The camera that was causing problems initially is still a problem, but now it's not uncommon for 5 and 6 other cameras to drop off at the same time. Sometimes with a blank screen, other times with freeze frames, and pixelation. V-I is telling me it's environmental interference but the system functioned just fine for the past 4 months with no problems. What would cause the system to start having errors on 1 camera and rapidly escalate to ALL cameras having issues? The client is obviously unhappy, and I've been in hyper damage controll mode for the past 2 weeks trying to get this problem taken care of, and it's only getting worse. Here's some more details about the system. 18 cam analog RJ56 / 18 gauge siamese cable longest run is around 250' one 16 port 24VAC powersupply completely filled up one 8 port 24VAC powersupply with 2 ports in use I'm in dire need of some experienced assistance here, and info would be helpful at this point. Thanks in advance.

I wish I had a handheld But this is the only analog system I've installed, everything else has been IP, so once I got past this install, the need went away, and thus the desire to get one. All the connectors are 2 piece crimp ons. I've re-terminated almost every connection. I've gotten the problem to clear up somewhat by electrical taping the connectors at the head end for shielding. However, it still randomly drops 1 camera or has a uniform dimming across all cameras in a "wave" like motion. Since doing some basic shielding has helped but not eliminated the problem, I'm leaning towards the conclusion of environmental interference. Are there any advanced methods of shielding that may help further reduce or eliminate the issue? Also, what would have caused to it have these problems all of the sudden, and escalate in the fashion they have? Thanks for the insight.

I'm brand new t CCTV installation and am beginning my first install in a couple of days. I'm using 12VDC/24VAC external housings with heater and blower and cameras with a power consumption of 5.3 watts. Is it necessary to run separate power to each one or can I simply bridge off the camera to power the housing? Thank you very much.

Thank you kindly sir, thats what I was thinking.
