ACTi B928 5MP Outdoor Speed Dome PTZ Camera

The ACTi B928 is a 5MP outdoor speed dome PTZ engineered for wide-area surveillance in harsh environments. It delivers 36x optical zoom (4.6–165.6mm focal length), enabling clear identification from distance without sacrificing coverage breadth. Built-in IR LED array (850nm, 200m working distance) ensures 24/7 operation down to 0.003 lux minimum illumination in color mode — real utility for perimeter security, traffic enforcement, and industrial monitoring where darkness or backlighting is constant.

Imaging and Durability: The 5MP progressive-scan CMOS sensor (3096 × 2202 effective pixels) pairs with extreme WDR (120dB) to extract usable detail in mixed lighting without the halo artifacts that plague simpler algorithms. Mechanical IR-cut filter switches automatically between day color and night monochrome. IP66 weather sealing blocks high-pressure jets and dust; IK10 vandal rating (metal casing) survives deliberate impact. Operating temperature span of −40°C to 55°C qualifies the camera for arctic installations and sun-baked desert sites without thermal shutdown risk.

Pan-Tilt-Zoom Performance: Scan mode pans/tilts at 1.6°–64°/second; preset mode accelerates to 300°/second (0.16°–150°/second vertical). Preset accuracy holds ±0.265° across all axes. 256 preset points and 10 preset tours support repetitive coverage patterns (perimeter sweeps, parking lot quadrants). Manual pan/tilt via remote control offers real-time adjustment when scanning fails.

Video Codec and Streaming: H.265, H.264, and MJPEG compression let you right-size bandwidth per site—H.265 halves storage compared to H.264 on 24/7 recording. H.265 is the default choice for NVR systems handling multiple PTZs. ONVIF compliance (Profiles S, G, T, M) ensures integration with standard VMS platforms without vendor lock-in.

Analytics and Audio: Built-in video motion detection (VMD), people counting, and smoke detection offload basic threat filtering to the edge, reducing false-positive noise in central management. Two-way audio (line-in, line-out) supports intercom or alarm broadcast. Manual position setting via GPS enables asset tracking across multi-site deployments.

Power and Installation: PoE+ (802.3at, 75W maximum) or AC 24V input eliminates separate power runs on properly provisioned infrastructure. Single RJ-45 pigtail connector and modular design support wall, pole, pendant, corner, and rack mounting. Weight of 3.1 kg requires appropriate structural load planning.
