ACTi I51 5MP Indoor Hemispheric Dome Camera

Overview

The ACTi I51 is a 5MP indoor hemispheric dome designed for ceiling-mounted surveillance in retail, office, lobby, and institutional spaces where compact aesthetics and reliable day/night coverage matter. The I51 delivers 5MP resolution—enough to capture forensic-grade detail across medium to large indoor spaces—without the visual footprint of bullet or turret housings. Day/Night capability with infrared ensures continuous operation through low-light and dark conditions; WDR (Wide Dynamic Range) balances exposure in mixed lighting (bright windows alongside darker corridors) to prevent washout and preserve shadow detail simultaneously.

Compatibility

The I51 integrates into standard IP surveillance networks via Ethernet connectivity. It supports integration with leading VMS platforms and third-party management software that consume ONVIF-compliant video streams. Deploy across distributed indoor locations for centralized configuration, remote monitoring, and forensic retrieval via your existing network infrastructure. Specific VMS compatibility depends on your platform's ONVIF Profile support; confirm with your VMS vendor before large-scale deployment.

Installation Notes

The hemispheric dome form factor is optimized for ceiling mounting, reducing installation complexity in retrofit and new-build scenarios. Discrete profile suits spaces where visible security equipment must blend with interior design. Confirm ceiling mounting hardware is rated for the I51's weight (0.25 lb) and your specific ceiling type before installation. Network drops and PoE power delivery should be provisioned to the camera location; no separate power supply is required if your infrastructure supports PoE.
