2 MP (1920×1080) IP camera TRASSIR TR-D8321WDIR4 2.8 / 3.6 is designed for year-round outdoor use in direct access areas: the housing is protected against moisture and dust according to IP67 standard, and against mechanical impacts - IK10 standard. It operates within the temperature range of -40°C to +60°C and features surge protection up to TVS 4000 V.


Motion detection, face detection, human detection, line crossing detection, area entry and exit detection, loitering detection, vehicle detection, people counting.

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

3D DNR — reduces spatial noise in the image.

Defog — software-based reduction of blur caused by fog or smoke.

BLC — compensates for backlighting.

HLC — masks sources of local brightness.

Day/Night mode with ICR: in sufficient light, the filter blocks infrared rays, optimizing color reproduction; in darkness, it mechanically shifts away from the sensor to increase its sensitivity.

Cold start.


TR-D8351WDIR4 2.8 / 3.6 mm is based on a 1/2.7" CMOS sensor with a sensitivity of 0.003 lux. It is equipped with a fixed focal length lens: 2.8 mm providing a horizontal viewing angle of 99° and vertical angle of 72°, and 3.6 mm providing a horizontal viewing angle of 79° and vertical angle of 60°. It has an aperture of F/1.3, RJ-45 network port, audio input, audio output, alarm input, alarm output, and supports microSD cards up to 256 GB for storage. It supports compression codecs H.265+, H.265, H.264, and for night surveillance, it features IR illumination with a range of up to 40 meters. It includes built-in microphone for audio monitoring. The camera operates at a transmission speed of 25 fps with and without WDR enabled, with a bitrate of 8 Mbps. Power options include DC 12 V and PoE, with a maximum power consumption of 6.0 W. The dimensions are Ø93.0×92.2 mm and it weighs 400 grams.
