Power over Ethernet (PoE)
The BC820/BC820MP5 and the BC820H1 can also use Power over Ethernet (PoE), which
requires that IEEE 802.3AF Power Sourcing Equipment (PSE) is available on the network. The
use of Cat 5 Ethernet cable is recommended for network connection. For the best transmission
quality, limit the cable length to no more than 100 metres.
Connect one end of the Ethernet cable to the camera's RJ-45 connector and the other end of
the cable to the IEEE 802.3AF network switch or PC. The BC820 consumes 3.8 W of power.
Note: In some cases, you may need to use an Ethernet crossover cable when directly
connecting the BC820 cameras to a PC.

Alarm application
The camera equips one relay input and one relay output for alarm application. Refer to the
alarm pin definitions below to connect alarm devices to the IP camera as necessary.
The RS-485 connector is the interface for connecting with the camera's PTZ positioning
system.

Audio
The BC820 cameras support two-way audio transmission in full duplex, half duplex, and
simplex modes in a variety of audio qualities.

Micro SD storage
The BC820 cameras support a Micro SD card for storing motion detect and scheduled
recordings. Users can also format the SD card and implement automatic recording cleanup
through the setting page on the browser interface of the camera.
