Due to its IR lights and onboard heater for operation in low temperature environments,
care should be taken when selecting the power source for the camera. Listed below are
the requirements for powering the camera:
Use conditions
Camera + IR on + Heater on
Camera + Heater in day mode (w/o IR)
In warmer areas that do not need a heater, a PoE+ switch can drive the camera. In areas
where temperature can drop below -20ºC, an AC 24V power adaptor is required.
IMPORTANT:
Many copper coated aluminum (CCA) and other non-standard conductors cabling products
are masqueraded as CAT5E or CAT6 cables. Please avoid using these CCA products
especially when cascading PoE cameras. It is a must to use Ethernet cables compliant
with the 3P/ETL standard.
