    Key specifications
    Camera and field of viewThe 4 MP low-illumination CMOS camera covers 104° horizontally, 57° vertically and 113° diagonally. A Starlight image sensor holds detail in the dark and auto IR illumination (ICR) steps in.
    VideoUses H.264 and H.265 compression; the main stream runs at 1080p and climbs to 2512 × 1408. Video recording, snapshot capture and pre-record time all stay configurable.
    AudioA built-in dual microphone and speaker carry the conversation, with a 3.5 mm external input and output. Echo suppression and digital noise reduction cut the noise, and the unit sends audio and group broadcasts.
    Ports and alarmsCarries 2 × alarm inputs, 2 × alarm outputs, 2 × RJ-45 (10/100M) and 1 × RS-485 port. A tamper alarm reports any attack on the casing.
    Power inputRuns on standard PoE, takes a 12 VDC 3 A input and delivers a 12 V/1 A output.
    Housing and mountingThe silver aluminum alloy body carries IP65 and IK10 protection and sits on the wall with a surface mount.
