PTZ security cameras have a very unique setup in from the very start. They have power, video and data connection to deal with. But how does provide power to their PTZ security cameras? There are two ways to really do this. You can power independently or you can use an AC power distribution box. There are also some other hybrid solutions, but they require an AC to DC power converter and then splice your cable to connect a power supply box. We do not recommend this fabrication unless you have some serious experience as an electrician. However, there is one other way to power your PTZ camera and that is buy using CAT5 video baluns that have plug and play setup features and allow you to use a regular 12VDC power transformer and the camera's balun changes the voltage back to AC and from AC to DC for your local power supply. If you decided not to use video baluns for video, power or data, then you are left with RG59 cable. It would be wise to use cable that has video and power in the same jacket so you are not having to deal with running lines for video and power. However the end pieces on PTZ camera are in a block terminal form. There are screws that must help secure any 2.1mm pigtail adapter to connect the power to the surveillance cameras. The block terminals are best peace-of-mind solutions, because you never have to worry about your ends coming un-done over a few months to some years. Here is a example of what we are illustrating::

Here you can clear see the terminal for both power and data. This is where if you had RG59 with video, power and data wire in the same jacket, that you just match up the correct connections and fittings. When running power back to the security DVR, all you need to do is once again match up the right terminal on your power supply distribution box. Or if you are using video baluns, there is an adapter plug-in where you can use a regular 12VDC power supply transformer and let the balun regulate the AC to DC and DC to AC power conversion for your PTZ camera. Both ways are very good options, all you have to decide is on total plug and play or manipulating your own BNC and power lead ends for your CCTV applications. Video baluns offer that plug and play mentality because they have a port that takes Ethernet RJ45 connectors. However, this is overall a new and upcoming standard for video and powering of a PTZ security camera.
