ACTi B934 2MP Indoor Speed Dome PTZ Camera

ACTi B934 2MP Indoor Speed Dome PTZ Camera

Overview

The ACTi B934 is a 2MP indoor speed dome PTZ engineered for institutional surveillance across retail, education, and corporate facilities where motorized pan-tilt-zoom coverage simplifies multi-zone monitoring from a single mount point. The B934 delivers 30x optical zoom (4.5–135 mm focal length), enabling operators to transition from wide-area overview to evidence-grade detail on demand without swapping cameras or losing sight of surrounding activity.

Key Capabilities

• 30x Optical Zoom: Wide-to-tele transition in 2.4 seconds reduces blind spots in large open spaces; 256 preset points and 10 preset tours automate recurring surveillance patterns without manual intervention.
• WDR (145 dB): Balances exposure across mixed-light scenes (sunlit entryways, dimly lit corridors) — eliminates the blown-out or crushed-shadow problem that forces you to choose between floor and window detail.
• IR Night Vision: 0.002 lux color sensitivity; switches to B/W mode with IR LEDs for near-total-darkness monitoring without visible illumination — critical for 24/7 retail or after-hours facility monitoring.
• PoE+ (802.3at) Power: Draws full power from a single Ethernet run; eliminates separate power conduit and simplifies retrofit installations in existing ceiling grids or wall cavities.
• IK09 Impact Rating: Withstands 20 joules of direct vandal contact — relevant in high-traffic public spaces or detention environments where dome domes face exposure.
• Video Motion Detection + People Counting: Built-in analytics trigger alerts on motion or count occupancy without external edge processing — reduces false alarms and supports occupancy-driven building automation.
• ONVIF Compliance: Profiles S, G, T, Q, M (via future firmware) ensure interoperability with third-party VMS platforms; no vendor lock-in on system upgrades.
• H.264 + MJPEG Compression: H.264 main profile cuts bandwidth 30–40% versus baseline — material when recording 24/7 across multiple PTZ units on constrained corporate networks.

Audio & Integration

Two-way audio (mic-in, line-in, line-out) enables remote communication and environmental sound logging. Manual pan-tilt positioning speed reaches 54.4° per second; scan mode delivers 720° per second for rapid area sweeps. Preset accuracy of ±0.265° ensures repeatable framing on fixed zones.

Environmental & Physical

Operating range −20°C to +50°C (−4°F to +122°F) covers most climate-controlled interiors; 3.47 lb weight permits ceiling, wall, pole, pendant, corner, and rack mounting without reinforcement in standard drywall or suspended grids. Horizontal resolution of 1450 TVL translates to clean 1080p-equivalent sharpness on 2MP output.

When to Evaluate Alternatives

If you need 4K or higher for evidence-grade facial recognition at distance, step to a higher-megapixel PTZ in the same family. If the scene is purely outdoor and exposed to rain, confirm IP rating requirements — the B934 is rated for indoor use only.
