Male-Female Connectors and Power Supplies

When installs cannot be completed because of an overlooked connector, the install can’t be completed. So when ordering equipment, for each camera run, you have to think about power and video.

There are many different BNC connectors and baluns.  The type and brand are not important.  For now just remember to get two (2) per camera run.

POWER LEADS

Power can be a little more complicated.  If the camera has a female power lead on it (which ALL 12v and some dual voltage cameras do) then a male power lead is required for EACH camera.  24 volt and some dual voltage cameras have terminal blocks on them and do not require power leads.

If you are using a plug in power supply at the DVR for the cameras then you will need a female power lead for EACH camera.  If you are using a power supply box with terminals, female power leads will not be necessary.

BALUNS FOR CAT5

For Cat 5 power cable, each side of the run needs a balun for video transmission.  One balun will go into the camera and a second will go into the DVR.  For one camera you need 2, for 4 cameras you need eight, etc.  To supply power, you may need male and or female power leads depending on the power supply and camera.

BNC FOR SIAMESE

For Siamese cable, each side of the run needs a BNC connector for video transmission.  One BNC will go into the camera and a second will go into the DVR. For one camera you need 2, for 4 cameras you need eight, etc.  To supply power, you may need male and or female power leads depending on the power supply and camera.

A word of advice to close, when in doubt buy extra. You need 8 BNC connectors, buy 10.   For power leads, you may ask one of our technicians. If you are unsure whether a camera needs it or not it is better to just get them and if you need 8 get 10.
