The Dahua H3B is a 3MP indoor fixed-focal Wi-Fi pan & tilt camera built for households that want dependable room coverage with a strong focus on communication and awareness features. With pan rotation up to 350° and tilt from -5° to 80°, a single camera can scan an entire room without leaving blind spots.
Coverage and clarity go hand in hand with the Dahua H3B. The camera uses a 1/3.2″ CMOS sensor with a maximum resolution of 2304 x 1296, encoded through H.265 compression for efficient bandwidth use. A wide field of view, up to 117° diagonal with the 2.8mm lens option, makes it easy to capture an entire living room, nursery, or entryway from a single mounting point. Auto ICR day/night switching and DWDR help maintain image clarity across changing light conditions, while built-in IR illumination extends visibility up to 10 meters after dark.
Automatic target tracking is a standout feature here, keeping the camera locked onto moving subjects as they cross the room, whether that’s a family member, a pet, or an unexpected visitor. Combined with AI-based human detection, the camera reduces irrelevant alerts and focuses attention on activity that actually matters.
Communication and awareness features round out the Dahua H3B’s practical value. The camera detects abnormal sounds and sends prompt alerts, giving users an extra layer of awareness beyond simple motion detection. A one-click proactive call feature lets users start a conversation instantly through the built-in mic and speaker, useful for checking in with family or greeting visitors remotely. The Dahua H3B is also designed to regularly guard the places that matter most, making it a steady presence for ongoing home monitoring rather than just occasional checks.
Privacy is also built in, with a one-click privacy mode that lets users physically block the camera’s view whenever full monitoring isn’t needed — reassuring for shared or sensitive spaces.
Setup and remote access are handled through the DMSS app, compatible with both iOS and Android, giving users live views and playback from anywhere. The camera connects over 2.4GHz Wi-Fi (802.11b/g/n/ax) and stores footage locally via a microSD card up to 256GB, with no mandatory cloud subscription required. Power consumption stays efficient, ranging from 1.6W at idle to a maximum of 3.8W during active live view, IR, and pan-tilt rotation.
Compact and lightweight at just 206.5g, with dimensions of φ84mm x 123.8mm, the Dahua H3B fits easily into any indoor space. It operates reliably between -10°C and +45°C, backed by CE certification for dependable everyday home security.
