The 5 MP (2592x1920) IP camera TR-D3351WDIR4 2.8 / 3.6 is adapted for year-round outdoor use in areas with direct access. The housing is protected against moisture and dust according to the IP67 standard, and against mechanical impacts according to the IK10 standard. It operates in temperatures ranging from -40°C to +60°C and features surge protection rated at TVS 4000V.


· Detection of motion, faces, people, line crossing, area entrance and exit, loitering, vehicles, and people counting.

· IR illumination range of 40 meters.

· WDR 120 dB — eliminates the impact of varying light levels on image quality.

· 3D DNR — suppression of spatial noise.

· Defog — software removal of blur caused by fog or smoke.

· BLC — backlight compensation.

· HLC — masking of local light sources.

· Day/Night mode with ICR: in sufficient light, the filter blocks IR rays to optimize color rendering, and in darkness, it mechanically moves away from the sensor to increase sensitivity.

· Compression: H.265+, H.265, H.264.

· Streaming speed: 25 fps with WDR off, 25 fps with WDR on. Bitrate: 8 Mbps.

· Built-in microphone.

· Cold start.
