Unit connectors
Network connector - RJ-45 Ethernet connector. Supports Power over Ethernet (PoE). Using
shielded cables is recommended.
PoE classification switch - Power over Ethernet (IEEE 802.3af), selectable power classification:
• Class 2 - max 6.49W
• Class 3 - max 12.95W (default)
Note: Power classification is performed at power up. If the video encoder does not power the connected
analog camera, select PoE Class 2 to inform the PoE switch that the video encoder only needs max
6.49W. PoE Class 3 is the default setting.
Power connector - 2-pin terminal block used for power input or power output.
• Power input - To supply power to the video encoder with the supplied
power adapter or an external power supply 8-20V DC, max. 7.2W.
• Power output - the video encoder can supply power to an analog camera
or auxiliary equipment if powered by PoE, 12V DC max 5W (420mA).
Notes:
• The video encoder can deliver a maximum of 5W (420mA) with PoE. This includes the output on the power
connector and the I/O terminal connector.
• Do not connect a power supply if the video encoder is connected to PoE.
Audio in - 3.5mm input for a mono microphone, or a line-in mono signal (left channel is used from
a stereo signal).
Audio out - Audio output (line level) that can be connected to a public address (PA) system or an
active speaker with a built-in amplifier. A pair of headphones can also be attached. A stereo
connector must be used for the audio out.
