Try it with separate PSU that is a good idea. I just need very long extension lead and be there late evening. If I will get a chance I will do it. We are using LILIN PIH-8028P cams LILIN Infrared Illuminator Housing 80m PRH-5480 Lens Tamron-308ASIR 3mm - 8mm IR Corrective Vari Focal Auto Iris Lens Thanks Tom

It is long that true and now I have a look at the spec of balun and max power distance: Requires EZ-CAT-5 Dimension 47(L) x 25(D) + 20mm Video 25mm Power Output RJ45 Input Video: BNC Male 8 Max Distance Video 1000-1500 ft = 304-457m Max Distance Power POWER-THRU: 24VAC 5vA 517ft (157m) 10vA 259ft (78m) / 20vA 130ft (40m) 30vA 86ft Product Category Video Transmission It looks like to give it the most power I need to have PSU less than 40m from cam. And all those not working cams got the longest cables. The only one problem is that is a building site and there is no power around the holding. Looks like electrician need to draw 230V line. I think you guys got the right point of this just confirm please what I see from the spec of this balun. Thanks mates. Tom

That is my first post so hello to everyone. I am quite new in CCTV and I done quite big installation on building site. There are nine cams with infrared housing. Housing according to spec taking 2A Body cam according to spec taking 0.16A Lens 3mm - 8mm IR Corrective Vari Focal Auto Iris Lens We are using Muxlab Power Thru Balun to run power and signal to cams and housings over CAT5 cable. All that is powered by two PSU MCS6020B 20A We are using Vista SmartDisk10 as recording equipment. The problem is every thing is working well till dusk come right after that, I assumed camera want to switch to night mode. Some of the cams just losing signal and others getting horizontal straps for a while then losing signal completely. All I was thinking they don’t have enough power and we where using 10A PSU but now when we switch to 20A there is still the same problem. Now I am not sure that is electric problem or problem is with cameras setups. All installation is running on 24V AC. Each camera has separate CAT5 cable to run power and signal directly to it. The longest cable has 320m from PSU to housing. If anyone known how to solve this I will be the most grateful. If there is any other information what I can provide please just ask. Thanks Tom P.S. As a new user I can’t paste any links to specifications. I will do it ASAP.
