Overview
8 MP (3840×2160) IP-camera TRASSIR TR-D8281WDIR4 2.8 is adapted for outdoor use under the direct influence of precipitation — regardless of the time of year and day: the body is protected from dust and moisture according to the IP67 standard, operating temperatures from -40 °C… +60 °C, lightning protection - TVS 6000 V, range of the integrated IR illumination - 40 m.


Functionality

  • Detection of movement, persons, crossing a virtual line, abandoned objects; counting those who crossed the line.
  • Detection of intrusion into the zone, exit from the area (with filtering of people and vehicles).
  • Built-in microphone.
  • Additional LED-backlight operating in strobe mode.
  • Day/Night with ICR: in sufficient light, the filter refracts IR rays, normalizing color reproduction, and in the dark it shifts away from the sensor to increase its sensitivity and backlight efficiency.
  • WDR 120 dB - Reduces the impact of changes in light levels on image quality.
  • 3D DNR - spatial noise reduction.
  • BLC - backlight compensation.
  • Defog - Enhances contrast to reduce the effect caused by fog or smoke.
  • Compression H.264, H.265, H.264+, H.265+.
  • Main stream resolution - 3840x2160, 3200x1800, 3072x1728, 2560x1440, 1920x1080; additional - 1280×720, 704×576, 352×288.
  • The frame rate of the main stream is 15 fps (WDR on 8 MP), 20 fps (WDR off 8 MP, 6 MP), 25 fps (5 MP and below), additional - 20 fps. Bitrate - 13 Mbps.
