1 Installing a Recessed Mount
1.1 Description
This chapter details how to recess mount the AutoDome Junior.
1.1.1 Additional Requirements
– Appropriate straight slot screwdrivers
– No. 2 Phillips screwdriver
– Appropriate tool for cutting a hole in drywall or ceiling tile
(if applicable)
– 4 in. x 4 in. junction box (optional)
– T-10 Torx wrench
– VJR-A3-SP, support kit for VJR-A3-IC mounting kit
NOTICE!
The image sensors in modern CCD cameras are highly sensitive
and require special care for proper performance and extended
lifetime. Follow the guidelines for optimum results with your
camera:
– Do not expose to direct sunlight or bright spotlights in
operating and nonoperating conditions.
– Avoid bright lights in the field of view of the camera. Bright
lights cause a “smearing” effect, which is visible as white
lines above and below the highlight. Prolonged exposure to
bright lights may cause bleaching of the sensor's color
filters. This will be visible as colored spots in the picture
and is irreversible.
