Outdoor dome camera for surveillance installers

The Computar Ganz ZCOH5-DW55NXA is a new analog dome camera built for outdoor security systems. It delivers 700 TVL resolution through a 5-50mm computar varifocal lens with auto iris. The housing meets IP66 standards for impact and weather resistance. Installers can choose ceiling or wall mounting with a built-in conduit hole for cable routing.

Analog resolution and coaxial cabling limits

The camera outputs a standard analog signal capped at 700 TVL over coaxial cable. True WDR reaches 12600x to balance high-contrast scenes without digital artifacts. Minimum illumination sits at .3 lux color and .03 lux monochrome, while Sens-up 512x mode pushes sensitivity to .0006 lux. Smart Day/Night syncs with external IR LEDs, and 2D/3D noise reduction cleans low-light footage.

Dual-voltage auto-sensing eases power wiring

The unit accepts 12VDC or 24VAC and auto-senses the supply, removing the need for separate SKUs. Four pre-programmed profiles switch automatically to optimize image settings for changing conditions. A test pattern with color bars helps verify focus and wiring on site. The conduit entry simplifies cable management, but installers must still plan coaxial runs within analog distance limits.
