C5x Power Supply

C-series devices can be supplied with power via power-over-ethernet (depending on model) or via a 24V supply on the GPIO port. If a DC supply is connected it will be preferred over PoE.

Power over Ethernet

On PoE switches the camera registers as 802.3bt (“PoE++”) device with PD class 5 (40W). Depending on the switch/injector model, cable length and number of connected devices on the switch the camera projection power may need to be limited in software for stable operation for long flash times.

Note

We strongly recommend to only use PoE++ equipment supporting PD class 8 (90W) to support the peak power required during flashing, which will also minimize the need for reducing LED flash brighness.

Note

If 802.3bt (“PoE++”) is not available the devices will register as 802.3at (“PoE+”) PD class 4 (25W). Although certain PoE+ equipment will be able to power the device we do not support operation on 802.3at.

Note

C-series cameras will not be able to power on when the switch/injector provides only 802.3af (“PoE”) PD class 3 (15W) or lower supply.

Note

Not all devices support PoE operation. Devices without PoE supply carry ‘-NP’ as suffix in the model name.

DC Supply

The camera can be powered via a 24V 10A DC supply on the GPIO port. For reduced power requirement the projection power can be reduced in software.

Note

Peak power is only drawn for short time periods during the projector flash time! The average power requirement will be significantly lower. See Illumination topic for flash time and duty cycle limits.
