from dialing out. The proper wiring connection for an RJ-31x connector is<br />
described later in this chapter in the section “Installation Plans.”<br />
Coaxial Cabling<br />
Coaxial cable is used to transport video signals between video cameras <strong>and</strong><br />
monitors in home video surveillance systems. The quality of the video signal<br />
is affected if poor-quality cable or the wrong type of cable is used. Structured<br />
wiring st<strong>and</strong>ards recommend the use of RG-6 coaxial cable <strong>and</strong> F-type connectors<br />
for connecting cameras <strong>and</strong> monitors.<br />
Termination Points<br />
The main termination points for a home security system are contained in the<br />
control panel. All the sensors installed throughout the home are connected<br />
with low-voltage wiring <strong>and</strong> routed through walls to the central controller<br />
termination strip.<br />
The telephone line also has a termination point where it enters the control<br />
panel enclosure. An RJ-11 telephone jack is retrofitted with a RJ-31x jack.<br />
The four telephone wires are then terminated on the controller main connection<br />
bus with the other external cabling harness.<br />
In-house Services<br />
Several types of security <strong>and</strong> surveillance services are available to residential<br />
users that have been previously used only in larger commercial business systems.<br />
Smaller, scaled-down types of home video surveillance <strong>and</strong> monitoring<br />
systems provide an economical option for homeowners. Two types of systems<br />
that provide internal services to residential users are discussed in the<br />
following paragraphs.<br />
Video <strong>Surveillance</strong> <strong>and</strong> Monitoring Services<br />
Video surveillance <strong>and</strong> monitoring is a type of service that allows viewing of<br />
selected areas on the exterior <strong>and</strong> interior of the home to be made available<br />
to the residents. Identification of visitors can be verified using video cameras<br />
<strong>and</strong> monitors before opening a gate or front door.<br />
Interior video surveillance <strong>and</strong> monitoring cameras can be used to observe<br />
infants in a nursery or small children in a playroom area. Hidden cameras can<br />
be linked to a VHS recorder to record the identity of any intruder who might<br />
have eluded the security system sensors.
