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
Basic
The TR-D2281WDIR4 2.8 is based on a high sensitivity (0.005 lux) 1/2.8 inch Sony Starvis CMOS sensor. Comes with a fixed lens. Parameters: focal length - 2.8 mm, aperture - F / 1.8, horizontal viewing angle - 106 °, vertical - 58 °. Interfaces: RJ-45, audio output, audio input, alarm output, alarm input, microSD card slot up to 128 GB. Power supply - DC 12 V, PoE. Power - 6.8W max. Size - 176.2 × 68 × 68 mm, weight - 364 g.
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.
