Hazardous environments and harsh treatment can often defeat security measures of property and business owners, but the new MD20 Varifocal Dome Camera by Supercircuits Inc. is already earning a reputation for weathering torrential storms as easily as it defies malicious vandals.With high-resolution options providing up to a 600 line resolution, the MD20 features a rugged cast housing and a super-hard polycarbonate dome that makes it impervious to driving rain, snow, foul weather as well as the most malevolent prisoners, vandals and thieves. In addition, the MD20 gets an exact field of view in seconds with a 4mm to 9mm varifocal zoom DC-driven auto iris lens that ranges from a wide 79-degree to 35-degree field of view capturing just the camera view wanted.
