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
Basics
The TR-D8281WDIR4 2.8 is based on a high-sensitivity (0.005 lux) 1/2.8-inch Sony Starvis CMOS sensor. Equipped with a lens with a fixed focal length of 2.8 mm, aperture F / 1.8, horizontal viewing angle of 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 - 7.3W max. Size - Ø103.5×82.4 mm, weight - 330 g.
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.
