| Revew | DAHUA SD5A445GB-HNR 4MP 45x PTZ IP CameraThe DAHUA SD5A445GB-HNR is a WizSense network PTZ camera with a 1/2.8" 4MP CMOS sensor (2560x1440) and a 45x optical zoom lens (3.95-177.75 mm). It pans 360° endlessly and tilts from -15° to +90°, so a single camera covers a large open area such as a parking lot, yard, industrial site, construction site or street. Four IR illuminators reach up to 150 m in total darkness, and Starlight technology keeps the image in color in very low light. On-board AI includes perimeter protection with human and vehicle classification, SMD 4.0, face detection, people counting and auto tracking. The housing is IP67 dust and water resistant and IK10 vandal resistant, powered by PoE+ or a 24 VDC supply. 
Key features- 45x optical zoom - A 3.95-177.75 mm motorized lens with autofocus and an extra 16x digital zoom lets you watch the whole site and then zoom in on details such as faces or license plates from far away.
- Night vision up to 150 m - Four IR illuminators with zoom-linked smart control reach up to 150 m. Starlight keeps color down to 0.005 lux, and 120 dB true WDR balances bright and dark areas.
- Target tracking - Auto tracking keeps a person or vehicle in the frame while panning and zooming. Auto Patrol turns the camera toward a target that triggered a perimeter rule.
- AI analytics - Perimeter protection (tripwire, intrusion, fence climbing, loitering and more) with human and vehicle classification, SMD 4.0 that filters false alarms from animals and leaves, face detection, people counting and video metadata. With a Dahua recorder, AcuPick finds people and vehicles in recordings.
- Built for outdoor use - IP67 and IK10 housing, 6000 V lightning and surge protection and operation from -40°C to +70°C. 300 presets, 8 tours, 5 patterns and 5 scans.
- Installation and management - Powered by PoE+ (802.3at) or 24 VDC, 10 W basic and up to 22 W with illuminators, fan and heater. Micro SD up to 512 GB, ONVIF, and viewing in DSS and the DMSS app.
