First attempt - questions

[mogolman 0]

Hello, I am planning on installing a cctv analog system with 8 cameras. The distance from the DVR to the cameras will be from 25 meters to around 100 meters (maybe more). I am thinking of using cat5 cable, along with these:

 

My question is, how do I power the cameras? I believe i have to hook a power supple to the utp cable, and power will be transferred via the balun, is this correct? Also, what is the maximum distance for my 12v cameras, for enough power to be transferred to them via the above method?

 

Thanks!

You would plug the power supply's male barrel plug into the female barrel on one balun... then plug the other balun's male barrel plug into the female barrel on the camera. Power will then be sent down the UTP.

 

The maximum distance will depend on the cameras' current draw (especially with IR LEDs) and the actual output voltage of the power supply (12V regulated, which will actually be 12V, or unregulated, which will run closer to 16V), but I'd say you're probably fine at 100m.

First attempt eh, here's hoping you find it an enjoyable experience. I would recommend that while you have reasonable weather, get the outdoor cameras up and ready so that if the weather changes for the worst it won't stop you working.

I always put up outdoor cameras first if the weather is good. On the other hand if the weather is bad, start inside and be prepared to fit the outside cameras when the weather improves, then when and if the weather is bad you can be comfortable working inside the property and not risking life and limb up some wobbly ladder in the rain.

 

By the way, Cat5, good choice " title="Applause" /> " title="Applause" /> " title="Applause" /> Enjoy your project.

Hi. if this is your first system i would say change the type of baluns you will be using .... you will need network tools to wire those type of baluns plus you are going to be over 100m so a power change from 12 to 24v may be neeeded

 

 

 

these are much cheaper and easier to use. and you can use the existing pairs of your cat5 to run bigger power. if your going 100m

I'm not so new to the game, but new to long hauls.

 

As for the 12v loss at 100', I know they carry up to 165' BNC w 12v coaxial cable, consider that?

You could always run 18/2 along for the power?

Do a test run before install?

Good Luck?

Well I'm back, everything went fine, power audio & video run through the same cat5 cable at a measured cable distance of 87 meters, no problem with the IR LEDs. The camera is supposed to draw . Thanks everyone for your help Now off to put up those remaining 7 cameras .

Okay You'll be knackered after those so take a little rest between cameras so you can focus on the job.

I always do and a little rest between tasks can improve your concentration immensely. For health and safety reasons, never spend more than 30 minutes straight, on a ladder, take a break and continue refreshed. I always figure out what tools I think I'll need and put them in a bucket which O can hang under the ladder on a hook. A tool-vest can be useful but personally I prefer the old bucket. I don't like looking like some mechanical "transformer" and I find tool vests a little heavy as I am quite small in stature. You'll figure out your own way of coping with repeat installs and by the time you've done all the cameras you'll be slinging them up in 10 minutes.
