The Baluns I have is almost identical to the picture Rory posted. Only dirrerence is the BNC connector is silver. There is an item number VB-05 but no brand name. I ordered them through a local security company. I have to give them credit - at least they new what I was talkin about when I aske for a balun.

I was thinking that but I could find no other explanation. I wonder what else it could have been, I do know that I tied the lines together on the camera side (burned balun was on the dvr side) to check continuity but I am 99.9% sure that power was off at that time. I should also mention that sleep deprivation could have played a part this occured the morning after an all nighter.

I think I burned a balun as I relocated a camera without turning the power off it will probably take a week to get another one (unless I can buy/borrow one locally). Should I take the other balun off the line?

No it doesn't. The net effect is still to lower the DC resistance of the wires. Survtech, would you mind posting the link here, I still have a few more days of probation I came across the calculator trying to find out if triple cat5 would get me to 200ft - it does. Thanks for all of your help! Rory - If you're out there thanks a mil. I'll be looking for your input on Diginet DVR soon

I do not know if the fact that the wires are in contact only at the beginig and end affect this calculation. I can't post links yet but just google "Bidirectional Single-Gauge AWG Calculator"

Looking for picture or diagram showing wiring with balun, Cat5 & coax. I'm trying to come up with a tidy layout for 16 cams - 8 on cat5 w/baluns, 1 on coax and 7 on cat5 w/o baluns. Do you connect video feeds to a barrier strip or do they go straight to the baluns? I'm not sure if power is going to be local of central so I'm planning both ways.

Before we conclude let me ask, would it be better to join wire from 2 different cables. This should generate less heat which would result in less voltage loss. I saw this somewhere in all of my reading today. I'm sure I haven't done the argument justice.

I was lucky enough to get an empty electrical panel to house everything in the office. As far as why Cat5, the company that installed the system used Cat5 I don't recall being a choice.

I wasn't worried about burglary. When we first got cameras the power was in the store and every so often the plug would some how work it's way out. There is no lock but there are two screws. I could put a lock on there, do you think it's a good Idea/neacssary?

In both locations, there is room near the breaker panels. They won't be seen. It's just cramped - you're killing me here man. If you're not careful it could turn out to be work.

Don't have the specs on the power supplies right now but they look pretty solid. They are 12v, nine Cameras which is good because although I have 16 cameras 9 are in one store and 7 in the other. So if/when I do put them in the stores there won't be an issue. I honestly don't know why I am reluctant to put the power in the stores. The boxes have just been mounted to the wall & I've cut & labled the wires going from the supply to the camera junction box. To make the move now won't take much effort. It's just something unsetteling about the power being out there. Is there a security issue with the supplies being in the stores

Gotcha Rory I'll test first. How about this. I still have the individual 12V adapters that I took out. Can I just put power on the camera, do a rough connect on the camera, and test the line. Or do I have to install everything in it's final configuration?

Took out name of supplier - Can't vouch for the prouduct - It's their entry level infared, 12V, 1.4 watts & 300mA.

Wouldn't a load have to be on the line when I test? I'm replacing a couple of those cheap bullets. I'll put one of them on the line to test.

I was resigned to putting the power supplys in the store but I would really prefer to put them in the office. Please tell me that I can triple up! If I get 10.8 volts it would be ok? What is the effect of low voltage? As I said these cameras have been running on low voltage for some time now.
