Uniview 4MP Compact Dome with Smart IR 30m, Two-Way Audio, and Smart Intrusion Prevention
The Uniview 4MP compact dome camera captures 2688 x 1520 video at 30 fps through a 1/2.7-inch CMOS sensor and fixed 2.8mm F1.6 lens, delivering a 101-degree horizontal field of view with smart infrared illumination to 30 meters and 120dB wide dynamic range. At just 4.3 inches across and 0.49 pounds, the low-profile dome mounts flush against ceilings and soffits for discreet surveillance in retail, office, and residential environments. A built-in microphone and dedicated audio I/O terminals support two-way communication for live interaction with visitors or intruders, and alarm I/O terminals connect door contacts and sensors for event-triggered recording. This security camera runs on Power over Ethernet (802.3af, max 4.5W) for single-cable installation and carries IP67 weatherproofing for outdoor deployment.
Smart intrusion prevention classifies human, vehicle, and non-motor vehicle targets for line crossing, intrusion zones, and area entry/exit detection, while people counting tracks flow and density for capacity management in retail and commercial spaces. Ultra 265 compression reduces storage requirements beyond standard H.265, and onboard microSD supports cards up to 512GB with ANR failover for continuous recording during network interruptions. NAS support via NFS enables centralized storage, and ONVIF Profile S, G, T, and M compatibility ensures integration with third-party NVR and VMS platforms. The 4KV surge protection safeguards the camera against electrical spikes on exposed outdoor cable runs.
Where the Compact Dome Fits
- Retail ceilings, office lobbies, and reception areas where the 4.3-inch low-profile dome blends into ceiling tiles without drawing attention, the 101-degree field of view covers wide service counters and entry points from a single overhead position, and people counting tracks customer flow and occupancy for business intelligence
- Apartment hallways, stairwells, and common areas where the 0.49-pound housing mounts easily on drywall and drop ceilings without structural reinforcement, smart IR adjusts intensity to prevent overexposure in narrow corridors, and two-way audio through the built-in mic and external speaker lets property managers communicate with visitors remotely
- Warehouse entries, stockrooms, and restricted access points where smart intrusion prevention classifies human and vehicle targets to reduce false alarms from forklifts and carts, the alarm I/O terminals integrate with door contacts for access-triggered recording, and 512GB onboard storage with ANR provides backup recording independent of the network

Is 4MP Good for a Security Camera?
4MP resolution (2688 x 1520) delivers 50% more pixels than 1080p Full HD and provides enough detail to identify faces and read license plates at typical surveillance distances. For most commercial and residential applications, 4MP strikes the optimal balance between image clarity and storage efficiency, capturing more detail than 2MP without the bandwidth and storage demands of 4K. Paired with the 120dB WDR and F1.6 lens on this Uniview dome, the 4MP sensor produces sharp footage across challenging lighting conditions from daylight through complete darkness.
