Wiring Considerations
Power Cables
The TCAM2000 PT series only accepts 24VAC. In most cases Systems with
Intelligence will supply a junction box which converts the voltage level from
120VAC/240VAC to 24VAC. The gauge of the power cables should be chosen carefully
as long cable lengths could induce significant voltage drops due to the wire
resistance. Table 5-1 shows the resistance of some popular wire gauges for the CCTV
power cable.

20.95 Ohms

13.17 Ohms

5.21 Ohms
When a junction box, as shown in section 4, is used other voltages may be supplied to
the junction box and they are then converted to 24VAC. The voltage levels supported
by the junction box will vary based on model.

Maintenance – General Recommendations
The TCAM2000 does not require a special maintenance, however regularly scheduled
maintenance prolongs the operational life and appearance of the camera. Part of this
maintenance should also include verifying that all mounting hardware is secure. When
needed clean the viewing window with a mild, nonabrasive detergent in water and a
soft cloth
