Key Specifications
8 MP (3840×2160) IP-camera TRASSIR TR-D2281WDIR4 2.8 is designed taking into account the conditions of year-round outdoor operation under the influence of precipitation: the case is protected from dust and moisture according to the IP67 standard, operating temperatures from -40 °C ... +60 °C, lightning protection — 6000V.
Functionality
Detection of movement, faces, virtual line crossing (with counting), left objects.
Detection of intrusion into the zone, exit from the area (with filtering of people and vehicles).
Built-in microphone.
IR illumination with a range of 40 m.
Additional LED-backlight operating in strobe mode.
Day/Night mode with ICR: When there is enough light, the filter blocks IR rays, and in the dark it moves away from the sensor to increase its sensitivity and illumination efficiency.
WDR 120 dB - minimizing the effect of different contrast lighting on picture quality.
3D DNR - noise reduction.
BLC - software correction of the overexposed background.
Defog - Contrast enhancement to reduce the effect caused by fog or smoke.
Compression H.264, H.265, H.264+, H.265+.
