OPERATION
Concealed Camera Ports
There are three concealed camera ports on the Utility Box. Each port
is disguised with an ELECTRICAL PANEL IN USE label. Keep the label
surface clean and free from scuff marks. Make sure nothing blocks this
area.
A combination of two labels and an interior screen are installed per
window. Three additional labels (one per window) are also included in the
accessory kit. The installed label set and interior screen will provide the
best camera performance while balancing covert appearance issues, such
as reflection and light penetration from the other windows. The additional
(accessory bag) labels can be customer-applied if desired. You must be
willing to accept some honeycomb effect in the video at lower camera zoom
settings in order to cover up the tinted glass area of the windows.
Ventilation and Thermal Considerations
The Utility Box has a louvered exhaust vent on the back and a wire mesh
intake vent on the bottom of the enclosure. A cooling fan is mounted inside
of one of these ports. The cooling fan and heater run automatically to keep
the MiniBox-4 operating temperature between –20C (-4F) and +50C (122F).
Foam mesh
filtration protects against water/dirt invasion.
Optional Analog and Digital transmitters feature a thermal shut-down
circuit to protect the transmitter if the inside of the MiniBox-4 gets too
hot. Always remove obstructions from the vents to ensure good air flow.
Vacuum the bottom vent to remove excess dust, Remove the rear louvers,
clean and replace the foam filter if needed.
Do NOT block airow to vents at
back and bottom of MiniBox-4
