IMPORTANT:
1. The camera can be driven by an Ethernet connection to a PoE Plus switch (30W output). You
can connect both the PoE Plus and the 24V power for fail-safe redundancy.
2. If the installation requires heating in the winter (<-5ºC), you require approximately 60 Watts of
power to drive the embedded heater. You can either connect the 24V power lines or a High
Power PoE power injector (separately purchased).
