Description
Dahua DH-SDT4E425-4F-GB-A-PV1-S2 – a Smart Dual Light PTZ camera with two channels: a panoramic one for general control and a detailed one for zooming in on the desired area. It shoots 4 MP at 25 fps and is suitable when it is important to see the entire scene simultaneously and quickly examine details. Video transmission goes with modern H.265+/H.265 compression and Smart codec options to save space in the archive without unnecessary loss of quality.
Two channels and precise zoom
The panoramic camera provides a wide view of up to 101° horizontally, making it easier to monitor passages, parking lots or the area around an object. The detailed channel with 25x optical zoom and a 5–125 mm focus helps to zoom in on the desired area and read the situation at a distance. The PTZ mechanics rotates 360° without restrictions and tilts up to 90° with auto-flip, making it more convenient for the operator to follow the target. The default speed of up to 240°/s accelerates the translation to the desired point in case of an alarm.
Night surveillance and operation in difficult lighting
Smart Dual Light combines IR illumination and white light: the panorama works up to 30 m, and the detailed channel – up to 100 m with IR and up to 50 m with white light. High light sensitivity and 0 lux mode with illumination enabled help maintain the picture at night. WDR 120 dB, BLC/HLC and 2D/3D NR noise reduction support reading the frame in backlight, headlight glare and sharp brightness changes.
Analytics, sound and archive storage
The camera supports events such as line crossing, intrusion, fence violation, crowding, as well as abandoned or missing objects and fast movements; alarms can be divided into "human/transport". There is SMD 4.0, person detection and audio exception control, plus reactions to interference, network disconnection and IP conflict. Recording can be done on MicroSD up to 512 GB, as well as NAS or via FTP/SFTP; 3 streams, ROI and ONVIF compatibility (Profile S/G/T) are provided. Power supply - 12 VDC or PoE 802.3at, the case with IP66 protection is designed to operate at -40 °C - +65 °C, and the built-in microphone and speaker together with audio/alarm interfaces help to link the video to events at the facility.
