The indoor 4 MP (2560×1440) IP Camera TRASSIR TR-D4S1 v3 3.6 is suitable for night surveillance, equipped with IR illumination with a range of 20 meters. It supports detection of people, motion, virtual line crossing, and intrusion into the area, as well as protocols TCP/IP, HTTP, FTP, DHCP, DNS, DDNS, RTP, RTSP, RTCP, PPPoE, UpnP, SMTP, and ONVIF.

Functionality:

· WDR 105 dB: Minimizes the impact of lighting variations on image quality.

· 3D DNR: Suppresses spatial noise.

· Defog: Enhances contrast to neutralize blurring caused by fog.

· BLC: Compensates for backlighting.

· Day/Night Mode with ICR: In sufficient light, the filter refracts IR rays to normalize color reproduction, while in darkness, it mechanically shifts away from the sensor to increase its sensitivity.

· Compression: H.265+, H.265, and H.264.

· Transmission speed: 25 fps. Bitrate: 8 Mbps.
