The SECO-LARM Vandal-Resistant Varifocal Color Dome Camera is protected against attack by a tough all-metal enclosure (weight 4 1/2 lbs.) and a high-impact smoked plastic dome. The camera itself features a Sony 1/3" Super HAD CCD chip and a digital signal processor (DSP) for superior picture quality under a variety of lighting conditions. The camera also includes a built-in 4~9MM Varifocal-type DC-drive auto iris lens, Auto Electronic Shutter (AES), Auto Gain Control (AGC), Backlight Compensation, Auto White Balance, and flickerless mode, and works with either 24VAC or 12VDC.
