The DH-SD5A825GA-HNR is an 8MP (3840 x 2160) PTZ camera with 25x optical zoom, for covering a car park, a yard or a building perimeter from one point. The 5.4-135 mm lens spans a 61.6 degree wide view down to 3.6 degrees, and the 4K sensor keeps detail when you zoom into a recording after the event.
Auto Tracking 3.0 lets the camera follow a moving person or vehicle on its own once a rule is triggered. Perimeter protection (tripwire, intrusion, climbing fences, loitering) and SMD 4.0 are aimed at people and vehicles. Four IR illuminators reach up to 150 m, and Starlight+ imaging holds colour down to 0.005 lux.
It runs from a single PoE+ (802.3at) cable or 24 VDC, drawing up to 21 W with IR and PTZ running. The housing is IP67 and IK10 with TVS 6000 V lightning and surge protection, and rated -40 C to +70 C, so it suits exposed outdoor mounts.

Compare other Dahua PTZ cameras: Dahua DH-SD5A425GB-HNR (4MP, 25x zoom), Dahua DH-SD5A445GB-HNR (4MP, 45x zoom).
Dahua lists this camera in its WizSense series, a range of AI products that use an independent AI chip and deep-learning algorithms and focus on humans and vehicles. Our WizSense guide explains the range.
Yes. Dahua lists a 1/1.8" 8MP sensor with a maximum resolution of 3840 × 2160 (4K). The main stream can also run at 4M, 3M, 1080p, 1.3M or 720p at up to 25/30 fps.
An 8MP stream uses more bandwidth than the 2MP and 4MP models: Dahua lists H.265 bit rates of 51 kbps to 12,288 kbps and H.264 bit rates of 128 kbps to 16,384 kbps. Smart H.265+ is designed to reduce bit rate and storage, by up to 70% according to Dahua.
Dahua lists IR illumination up to 150 m, with 0.005 lux minimum illumination in colour, 0.0005 lux in black and white and 0 lux with the IR on. Our Starlight guide explains Starlight low light imaging.
Auto Tracking 3.0 controls the pan, tilt and zoom actions of the camera to follow an object in motion and keep it in view. It can be triggered manually or by defined rules, after which the camera can zoom in and track the target automatically.
Dahua's DORI figures are in the table above: detect up to 2,700 m and identify up to 270 m. DORI follows the EN 62676-4 standard and does not reflect the distances of intelligent functions.
Yes. It has IP67 and IK10 ratings with TVS 6000 V lightning, surge and voltage transient protection, and Dahua lists an operating range of -40°C to +70°C.
It needs a PoE+ (802.3at) port or a 24 VDC 2.5 A supply, and draws up to 21 W with IR and PTZ active. A standard 802.3af port does not supply enough power.
It has a 1-channel audio input and output on bare wires, so it needs an external microphone to record sound. Check local privacy rules before recording audio.
It conforms to ONVIF Profile S, G and T, so it can generally be added to an ONVIF-compatible recorder for video and PTZ control. Dahua-specific features such as Quick Pick need a Dahua AI NVR.
