Dahua DH-SDT4E425-8P-GB-APV1 Panoramic + PTZ AI Camera for Enterprise Security

The Dahua DH-SDT4E425-8P-GB-APV1 is a professional dual-channel PTZ Speed Dome camera designed for security systems that require simultaneous panoramic coverage and precision optical tracking at extended distances. Combining an 8MP overview channel with a 180° field of view and a 25× optical zoom detail channel at 4MP resolution, this PTZ surveillance camera provides complete coverage of large areas — parking facilities, industrial perimeters, critical infrastructure, and expansive public spaces — without requiring multiple independent cameras. The right choice for system integrators and end users who need active monitoring with long-range identification and advanced AI detection capabilities.

The detail channel with a 5–125mm varifocal lens and 25× optical zoom enables person recognition at 500m and identification at 250m according to the DORI EN-62676-4 standard, covering long-range perimeter surveillance scenarios. IR illumination of 100m and warm light at 50m on the detail channel ensure complete day/night visibility, complemented by 120dB WDR for extreme contrast conditions. The integrated AI suite includes SMD 4.0, IVS with tripwire, intrusion, loitering detection, and human alarm classification, plus WizTracking powered by Xinghan large-scale AI models for automatic tracking of people and vehicles across wide areas.

The camera supports local storage on Micro SD cards up to 512GB, NAS, and FTP/SFTP, and integrates into VMS platforms via ONVIF Profile S/G/T, SDK, and CGI. PoE 802.3at power delivery eliminates the need for a dedicated power supply, simplifying installation within existing network infrastructures. Active deterrence through red-blue warning lights and a siren with 11 preset and 10 customizable sound alarms transforms the camera from a passive recording device into an active incident prevention system. IP66 protection, an operating temperature range of –40°C to +65°C, and TVS 6000V lightning protection ensure reliable operation in extreme weather conditions and harsh industrial environments.

Recommended for security system integrators, industrial facilities, critical infrastructure operators, airports, large parking areas, and extended perimeters requiring a dual-channel AI PTZ camera with WizTracking automatic tracking, IVS perimeter detection, and integrated active deterrence. The right solution for professional surveillance projects where a single camera must functionally replace multiple fixed devices.
