DESCRIPTION
The EX49 “No-Grip” High Impact Dome
Camera for a Vari Focal “Auto-Iris” lens has
been engineered for surveillance in hostile
environments. Compact and good looking, the
camera features a smooth “no-grip” housing for
protection against theft and vandalism.
An aluminum housing, CNC-machined from a
billet, with an impact resistant polycarbonate
dome and locking retaining ring, make it
extremely rugged and weather-tight.
For viewing adjustment, the CCD Camera/Lens
Assembly can be fully rotated using a unique
“Pan-Tilt-Twist” (PTT) mounting bracket.
A voltage regulator circuit allows for 12V dc or
24V ac operation, and a range in between, also
providing protection from voltage surge,
transient spikes, and reverse voltage.
The EX49 is available in several models
designed to meet specific needs.
