Camera Locations<br />
<strong>Surveillance</strong> cameras can be mounted outside the home to provide recognition<br />
of someone wishing to enter the security perimeter area, such as a front<br />
door or driveway gate. They should be located where no blind spots exist or<br />
where it is not practical to use other types of sensors. Cameras can be mounted<br />
on any surface area of the home or garage where coverage is required as<br />
long as the area is illuminated sufficiently at all times after dark. They are<br />
often used in the interior of the home to monitor a child’s playroom or nursery.<br />
Although not usually a problem in a residential application, certain legal<br />
implications are involved in using video surveillance cameras. They are not<br />
to be used where there is a reasonable expectation of privacy by individuals<br />
who are not aware that they are in a location where a camera is installed. This<br />
obviously does not apply to a person breaking into a business or home.<br />
<strong>Surveillance</strong> cameras can be used in most exterior residential locations; however,<br />
you should remember that a surveillance camera cannot be located where there is a<br />
reasonable expectation of privacy.<br />
Exterior <strong>Security</strong> Lighting <strong>Systems</strong><br />
Exterior lighting is often used to illuminate dark areas or areas to be protected<br />
using motion detection sensors that activate security lighting to deter<br />
an intruder. Dark areas surrounding the home where there are trees or<br />
shrubs are specific areas that need to be illuminated with security lighting<br />
systems. Motion detector-activated lights are also popular for exterior lighting.<br />
The most common <strong>and</strong> reasonably priced style is the two-floodlight<br />
design with the motion sensor mounted beneath them. The dual-lamp type<br />
exterior security lighting system is shown in Figure 3.9.<br />

Exterior security lighting should be used near l<strong>and</strong>scaped areas around the home,<br />
such as shrubs, bushes, foliage, <strong>and</strong> trees. <strong>Security</strong> lighting systems used during<br />
dark hours avoid the problem of allowing an intruder to enter the area surrounding<br />
a home <strong>and</strong> attempt entry while unobserved in a dark area.
