interruption of camera operation or video recording. This is mainly useful if you want redundant power
sources so that backup power will be available if one power source goes down.
Note: Seamless failover is only guaranteed when PoE Class 4 (25.5W) "full power" is available on the
PoE port. Auxiliary (Aux) power is always assumed to be “full power,” meaning that there is enough
power available for all possible camera functions. PoE, on the other hand, has many different power
classes and the product’s functionality depends on the PoE power class that is available.
If the PSE demotes the camera to PoE Class 3 (13W), the camera will boot and display an “insufficient
power” message. Therefore, if the camera is connected to a Class 3 PoE source while running on
Aux power and using full IR power and the Aux power source is disconnected, the camera will most
likely overload the PSE and reboot. However, if the camerais not using IR LEDs and Aux power is
removed, the Class 3 PoE power source would be adequate to guarantee seamless failover.
Important: There is a downside to having seamless failover if you aren’t using this functionality and
are connecting your cameras to PoE-enabled switches while running the camera on Aux power.
Since the PoE connection remains active when running on Aux power, if the camera is connected to
a PoE-enabled port on a switch, the switch by default will allocate some of its overall power budget
to that port.
Connecting to External Devices
External devices are connected to the camera through pluggable terminal blocks. For the locations of the
terminals, see Camera Module on page1.
The pinout for the I/O terminal block is shown in the following diagram:
