ACTi B911 3MP PTZ Camera with 10x Zoom Lens

ACTi B911 Concise Descriptor

The B911 is a 3MP outdoor PTZ camera engineered for fixed-position surveillance where zoom flexibility and robust environmental protection are non-negotiable. The 10x optical zoom lens (4.7–47mm focal length) gives operators the ability to capture wide context at 58° horizontal field of view, then narrow to tight 5.8° detail framing without sensor interpolation — critical when you need evidence-grade close-ups from a single vantage point. The B911 integrates into standard enterprise VMS deployments via full ONVIF compliance (Profile S, G, T, M) and ships with support for H.265 (bandwidth-cutting codec ideal for 24/7 streaming), H.264, and MJPEG.

Overview

Deploy this camera at entry/exit gates, parking structure approaches, loading docks, or building perimeters where you need motorized pan/tilt control without breaking the fixed-camera budget. The IP67 weatherproof rating and IK10 vandal resistance handle direct rain, dust, and impact from mounting-height bumps — genuine armor for outdoor unattended deployment. WDR (145dB spec) extracts usable detail in mixed-sun/shadow scenes common to outdoor industrial sites. The 940nm infrared (invisible light) delivers night vision without alerting intruders or triggering light-sensitive wildlife. Operating temperature range of -40°C to 60°C covers extreme cold warehouses and baking rooftops without re-rating. Power draw of PoE+ (802.3at Class 3) means standard enterprise PoE switches handle it without power-budget strain — no aux power supply needed.

Compatibility

The B911 works with any ONVIF-compliant VMS platform — Milestone XProtect, Axis Camera Station, third-party NVRs, and cloud recording gateways all recognize it. Supports Visca, Pelco-D, and Pelco-P PTZ protocols for integration with legacy control systems. Manual GPS position tagging integrates with asset-tracking workflows. Embedded analytics (video motion detection, people counting, smoke detection) execute locally — no external GPU required — and trigger native ONVIF events for alarm routing.

Installation Notes

Board-mount lens design — verify your mounting bracket accommodates this form factor. Preset pan/tilt positioning achieves 1.5° accuracy; confirm your application tolerates this precision floor. Manual pan/tilt speed reaches 54.72°/second (horizontal) and 27.36°/second (vertical); automated scan presets top out at 180°/second pan and 90°/second tilt — substantial but not fastest-in-class. Ten preset tours and auto-scan modes ease repetitive coverage patterns. Absolute position feedback ensures repeatable framing across power cycles.
