The Holowits E4A-4R(2.8) is a 4-megapixel infrared fixed dome IP camera built on a 1/3-inch CMOS sensor with a fixed 2.8 mm wide-angle lens (98 degrees horizontal). It combines 120 dB wide dynamic range, H.265/H.264 dual-stream encoding and infrared night vision with a built-in microphone and on-camera AI such as human-figure detection. An IP67-rated dome housing with 4 kV surge protection and PoE support makes it suitable for indoor and outdoor video surveillance.

Key features

• 4 MP (2560 x 1440) 1/3-inch CMOS sensor with fixed 2.8 mm F1.6 lens and 98 degree horizontal view
• 120 dB super wide dynamic range plus backlight and overcast scene adaptation for high-contrast scenes
• H.265/H.264 dual-stream encoding at 25/20 fps to reduce bandwidth and storage
• Infrared night vision (850 nm) with 0 lux capability and a built-in microphone for audio
• On-camera AI: motion, human-figure and lens-blocking detection
• IP67-rated, Class-C anti-corrosion housing with 4 kV surge protection; DC12V or 802.3af PoE
