5 OPERATING THE SR-SERIES THERMAL CAMERA
5.1 Advantages of Thermal Imaging
Originally developed for the military, thermal imaging cameras are now deployed in numerous
commercial applications where it is impractical or too expensive to use active illumination
(lights). They are perfect for wide-area surveillance in critical infrastructure or high-value
residence installations where lighting is unwelcome or impractical. The cameras also provide
improved daytime surveillance in environments where traditional CCTV security camera
performance suffers, such as in shadows, backlit scenes or through foliage.
Figure 5-1: Backlit daylight camera on left; thermal image on right
Observe that the setting sun in the backlit image on the left makes it difficult to discern any
objects of interest; the thermal image on the right is not affected by the bright sun and therefore
provides detail and contrast.
The SR-Series
is designed to be a drop-in replacement for current systems employing daylight
cameras. Initial setup of the system includes connecting power supply leads for the input power
and a BNC cable for monitoring output video. Optionally, a serial cable can be connected to
allow control of the camera settings.
5.2 Thermal Imaging
The SR-Series camera is a state-of-the-art thermal imaging
system that will provide you with excellent night visibility and
situational awareness, without any form of natural or artificial
illumination. The SR-Series camera is easy to use, but you
should take a moment to carefully read this section so you
fully understand how to interpret what you are seeing on your
display and how to use the controls.
