Key features

4PoE

Powers cameras directly

Four ports carry 36 W to the cameras in total, and a single port delivers up to 25.5 W.

8channels

1080p decoding

It decodes up to eight 1080p streams at 30 fps.

6attributes

Face attributes

It writes gender, age, glasses, expression, mouth mask and beard into the record.

10TB

Storage on a single disk

The SATA III port takes a disk of up to 10 TB.

HDMI output

The HDMI output reaches 4K resolution and works at the same time as VGA.

IN DAILY USE

Single-cable installEach camera draws video and power over the same network cable, with no outlet nearby.

AI searchIt scans stored images by channel, time and event type.

Event alertsIt triggers an alarm and sends e-mail on perimeter breach, face detection and disk error.

The total PoE budget is 36 W, so the connected cameras must draw less than that in total.
