Purpose-built dome camera

The Computar Ganz DCB-39 is a 600 TVL analog colour dome camera designed for indoor surveillance. It suits installers and property owners who need a compact, fixed-position unit with manual adjustment.

Build and daily handling

A 3-axis manual pan/tilt rotation bracket lets the installer aim the lens precisely after mounting. The unit fits a standard 4S gang box for clean indoor installation. Integrated 3-9mm varifocal lens allows focal-length selection on site without swapping optics. Low power consumption reduces load on the supply.

Upgrade path and fit

This camera replaces lower-resolution analog domes that lack wide dynamic range, backlight compensation or on-screen menu control. The jump is worth it when scenes contain strong contrast or when installers need motion detection, privacy masking and digital noise reduction in a single indoor housing.

Questions about this item

Does the 600 TVL resolution limit the detail I can record on an analog DVR?

The camera outputs 600 TVL, so the DVR will capture at that horizontal resolution; higher TVL cameras would show more detail on the same recorder.

What mounting hardware is required for the DCB-39 dome camera?

It fits a standard 4S gang box indoors and includes a 3-axis manual pan/tilt bracket for ceiling or wall positioning.

How do I adjust the 3-9mm varifocal lens and OSD settings on this camera?

Turn the lens rings by hand for zoom and focus, then use the tact switch on the camera body to navigate the on-screen menu for D-WDR, motion zones and privacy masks.
