ACTi - B77A - 6MP f1.65mm Outdoor Hemispheric Dome with IR LED 20m, WDR 130dB
Product Overview
The ACTi B77A is a 6MP outdoor hemispheric dome camera designed for wide-area surveillance applications. It features a progressive scan CMOS image sensor, f1.65mm lens, Extreme WDR at 130 dB, adaptive IR illumination up to 20m, and rugged IP68, IK10, and NEMA 4X protection ratings.
Key Configuration
Discontinued outdoor hemispheric dome camera; 6MP maximum resolution; progressive scan CMOS image sensor; 1/1.8 in. sensor size; 3096(H) x 2080(V) effective pixels; f1.65mm lens; adaptive IR LED x 18 at 850nm; 20m IR working distance.
Key Features
• 6MP hemispheric dome camera for outdoor wide-area surveillance
• Progressive scan CMOS sensor with 3096(H) x 2080(V) effective pixels
• Extreme WDR at 130 dB improves visibility in high-contrast scenes
• Adaptive IR LED illumination supports up to 20m night coverage
• IP68 weatherproof, IK10 vandal-proof, and NEMA 4X rated housing
• Superior low light sensitivity with 0.1 lux color and 0 lux IR illumination
• 1800 TVL horizontal resolution with 56 dB S/N ratio
Technical Context
The camera uses a 1/1.8 in. progressive scan CMOS sensor with 6.44MP effective pixel output. Minimum illumination is specified as color 0.1 lux at F2.8 and B/W 0 lux at F2.8 with IR LED on. Electronic shutter ranges include 1/5-1/16000 second in both manual and automatic modes.
Installation Notes
Because the ACTi B77A is discontinued, availability and replacement planning should be confirmed before use in new projects. Its IP68, IK10, and NEMA 4X ratings support outdoor installation when mounted and sealed according to site requirements.
