5. Power over Ethernet (PoE)
The
PoE
feature employed in DN1125 is available in models DN1125A4 and
DN1125B4. The standard units for power via 12VDC are models DN1125A1
and DN1125B1. For the detailed information, please see Data Sheet on Series
DN1125 IP Box Cameras.
5.1. PoE compatibility
With non Power Sourcing Equipment (PSE)
When it is connected with non PSE, the power adaptor should be connected.
With power adaptor
Connecting both PSE and power adaptor does not do any harm to the products.
Disconnecting power adaptor while it is operating does not stop operation. The
product continues to work without rebooting.
5.2. Power classification
The PoE Power Class supported by DN1125 is Class 0.
