How Many Connectors & Male/Female Power Considerations 5

Connectors for CCTV installs; what a boring topic, I am almost falling asleep writing this.  What is boring now turns crazy when installs cannot be completed because of an overlooked connector on an order.  For each camera run, we have to think about power and video.

There are many different BNC connectors and baluns.  The type and brand are not the focus here and will probably spark a debate between installers if mentioned.  For now just remember to get 2 per camera run.

Female Power LeadPOWER 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.

BalonBALUNS 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.  (Read our article on Cat5 vs Cat6)

BNC ConnectorBNC 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.  You will be glad you spent the extra $1.22 if one gets dropped from a ladder.  For power leads, ask one of our pros but err on the side of caution.  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.

  1. Thank you for all your helpful post….. It enabled me to correct erors made on installl… Kindly advice is it possible to use a 9 channel 12v 5A power distributon box using rj45 cable on 18 and 22 meter run.

  2. in analog for distance of 250 mtrs on cat 6 cable whether I can get video output which needs to be clear clarity. please suggest what needs to be done to achieve this.

  3. Hi guys,

    Got some questions regarding CCTV, BNC and CAT6.. Got a client that wants a CCTV solution for their small private housing village. Measured distance between camera and the central location of DVR is between 500 to 800 meters. I don’t want to go wireless as it cost too much hence the wired solution. Your suggestion will greatly appreciated.

    1.) What is the effective distance of BNC cable when used in CCTVs?
    2.) If i use CAT6 (lots of it lying around) is it OK to just connect/prolong it by soldering the wires together?
    3.) What is the effective distance of CAT6 when used in CCTVs and were just soldered together?
    4.) Is there a balun/device that can act as a repeater or strengthen/repeat the signals for CCTVs?

    Humbly,
