Overview
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+.
  • Main stream resolution - 3840x2160, 3200x1800, 3072x1728, 2560x1440, 1920x1080; additional - 1280x720, 704x576, 352x288.
  • 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.
