Rewiring My Security Alarm Power Source


Wiring and cable might not be the flashiest part of a security system but it is a critical part of the overall solution. There are plenty of things to consider when selecting and installing wire and cable to ensure your security system works optimally. At a minimum, wire will be used to provide power to your camera installation and most of the time, wire is also used to transmit the video camera signal back to the DVR.

To determine the appropriate cable for your security camera installation you must first know whether your system is analog or digital. Next, you need to know if your camera is going to be powered locally (connecting to it's power source within a few feet) or remotely. If you are connecting the camera to a remote power source, you should consider running your video and power cables together. Video security cables are available with the power and video cables run side-by-side (known as Siamese Cables) or all under one jacket. These will make installation much...

Components of a Doorbell System

Doorbell Wiring is relatively simplistic compared to the rest of your home wiring, and works on a much lower "safer" voltage. Lower voltage also means that smaller wires can be used, 18 awg wire at either 2 or 3 wire cables (depending on your wiring choice). Like most things electrical, making it work means completing the circuit, without creating a dead short.

Doorbell power source: small transformer, power by 110 v , with an output of much smaller voltage usually at 16 volts.

Doorbell buttons: A convenient means of completing the circuit, located and mounted on the outside of an entrance to the home, may be used at one door or at 2 entrances. 2 wires are hooked to connectors of the button assembly, when the button is pushed, the contact is closed and thereby making an electrical connection between the 2 wires, and the connection is broken when the button is released.
