The S1100w provides basic surge protection on all electrical lines. If you are installing the
equipment in a lightning prone or heavy lightning environment, or in a site where large AC
mains power fluctuations are a common occurrence, Verint strongly recommends that you
add additional external surge protection to all vulnerable connections. Vulnerable
connections are those that run for a long distance between the S1100w device and the
connected equipment.
The video camera is usually within a short distance of the S1100w transmitter; the S1100w
interface cable can be routed directly into the camera housing. Therefore, the video line
(and the serial port if using a PTZ camera) will seldom need additional protection. The
power feed usually runs down the mounting mast or wall for more than 20 feet
(7.6 meters); it is a good candidate for additional protection in a surge prone environment.
This protection will benefit both the camera and the device.

For the curious mind, a surge protector helps to clamp the surge to safe levels and divert its
energy to the earthing point, preventing device damage. Experienced installers know that
an effective surge protection must be installed with proper earthing and grounding.
