The Dotworkz D3 environmental housing sets the industry standard for design excellence in camera protection from the rigors of outdoor use, vandalism and physical damage. To offer this superior performance in a cost-effective, all-weather package, Dotworkz has incorporated its proven Heater/Blower system into the D3 architecture. It is ideal in weather conditions ranging from 30degrees F (-1degrees C) to 95degrees F (35degrees C), where it will maintain PTZ cameras at optimal operating temperature. Excessive cold and heat could potentially damage sensitive IP and analog cameras. To combat the cold, the unit's heater automatically activates at 40degrees F (4degrees C) and deactivates at 60degrees F (15degrees C) with a thermal cut-off assuring safe heating operation. The blower remains on at all time, keeping cameras cool and fog free. T:
