ACTi B923 3MP Video Analytics Indoor Speed Dome

ACTi B923 3MP Indoor PTZ Speed Dome

Overview

The ACTi B923 is a 3MP compact PTZ dome engineered for indoor surveillance in retail, education, transportation hubs, and corporate facilities where you need flexible optical zoom and real-time analytics without external processing. The B923 delivers 30x optical zoom (4.5–135 mm focal length), enabling capture of fine detail across large monitoring areas. At 0.003 lux minimum illumination in color mode and supported by IR sensitivity (700–1100 nm), the B923 performs reliably in dimly lit spaces. WDR processing handles mixed-lighting scenes—windows alongside overhead fixtures—without halo artifacts. IK09 impact rating protects the dome from intentional or accidental damage in high-traffic environments. Compact and lightweight (3.48 kg), the B923 mounts to wall, ceiling, pole, pendant, corner, or rack configurations, simplifying retrofit deployments.

Compatibility

The B923 integrates with ONVIF-compliant video management systems supporting Profile S, Profile G, Profile T, and Profile M. PTZ control is available via VISCA, Pelco-D, Pelco-P, and ACTi URL protocols. Onboard video analytics—motion detection (VMD), people counting, and smoke detection—operate natively on the camera without downstream VMS license overhead. Two-way audio (microphone input, line input, line output) enables synchronized sound recording or intercom workflows. The single RJ-45 Gigabit Ethernet port connects to any standard PoE+ (IEEE 802.3at) switch or standalone DC 12V power supply.

Installation Notes

The B923 operates from −20°C to 50°C, suitable for temperature-controlled indoor spaces and entry vestibules with seasonal exposure. PoE+ (802.3at) delivers sufficient power without a separate PSU in most deployments; confirm your switch's per-port budget against a peak draw of approximately 13W. The board-mount lens requires careful alignment during installation to avoid zoom-focus binding. Preset pan/tilt speeds reach 720°/second (pan) and 360°/second (tilt), enabling rapid repositioning on event triggers or operator commands. Manual panning ranges from 0.16° to 54.4°/second for smooth tracking. Absolute position feedback ensures pan (360° endless) and tilt (0°–180°) accuracy across power cycles.
