Overview
The Hikvision DS-2DE4A425IWG1-E 4MP 25x Zoom DarkFighter AcuSenseHikvision AcuSense NVR Range 2026: Sizing Guide 4-inch PTZ Dome Camera 50m IR is a 4MP 4-inch PTZ Dome IP camera with DarkFighter / AcuSenseHikvision AcuSense NVR Range 2026: Sizing Guide, 25x optical zoom and 50 m IR night vision. Its 25x optical zoom (4.8 to 120 mm) brings distant subjects in for identification while the pan-tilt mechanism (0° to 360° pan, -5° to 90° tilt) covers the whole scene from a single mounting point. It sees in colour down to 0.005 lux and in black-and-white to 0.001 lux (0 lux with the built-in illuminator). 120 dB wide dynamic range handles scenes with strong backlight. AcuSenseHikvision AcuSense NVR Range 2026: Sizing Guide deep-learning analytics classify people and vehicles so alarms are not triggered by animals, foliage or weather. Smart tracking (manual tracking, auto-tracking) follows a moving target automatically. Managed with Hik-Connect, iVMS-4200 and HikCentral and compatible with Hikvision NVRs and ONVIF systems.
