The ACTi B21 is a 5MP day/night box camera designed for versatile indoor and outdoor surveillance applications. It combines high-resolution imaging, a 12x optical zoom lens, H.264 video compression, PoE support, and audio capability for flexible security monitoring.
5MP day/night box camera; indoor and outdoor surveillance use; 12x optical zoom lens; f5.2-62.4mm focal length with F1.8-F3.0 aperture; DC iris and auto focus; H.264 video compression; PoE and audio support.
• 5MP resolution delivers clear and detailed video monitoring
• Day/night functionality supports continuous surveillance in varied lighting
• 12x optical zoom lens captures distant details with flexible framing
• f5.2-62.4mm lens with F1.8-F3.0 aperture, DC iris, and auto focus
• Basic WDR improves visibility in mixed bright and dark scenes
• H.264 compression supports efficient video transmission and storage
• Event triggering enables customizable security responses
The B21 combines megapixel imaging with a motorized zoom lens configuration for applications that require both wide coverage and closer subject detail. Basic WDR helps balance high-contrast scenes, while H.264 compression reduces bandwidth and storage demands compared with less efficient video formats.
PoE support can simplify installation by carrying power and network connectivity over a single Ethernet cable. For outdoor deployments, the camera should be installed with an appropriate protective housing, mount, and weather-rated cabling accessories.
