Computar Ganz ZN-DT1A H.264 Dome Camera

The Computar Ganz ZN-DT1A is a H.264 HD optimised dome camera designed for indoor surveillance installations. It captures 720p video using a 1/2.5” progressive scan CMOS sensor and supports true day/night performance for reliable operation in varying light conditions. Triple power options of 12VDC, 24VAC, or PoE simplify integration into existing infrastructure. The camera is ONVIF compliant and made in Japan.

Installation and Common Issues

The built-in 3.3-12mm MFZ varifocal lens allows remote zoom and focus adjustment, reducing the need for physical ladder work during setup. Plug-and-play compatibility with PixelMaster embedded NVRs eliminates manual network configuration for those recorders. Dual streaming video and bi-directional audio support add flexibility but require sufficient bandwidth planning. External alarm I/O terminals demand correct wiring polarity to avoid triggering false events.

720p Resolution Determines Suitability

This model delivers a maximum resolution of 720p, which defines the level of detail available for identification tasks. Buyers who need facial recognition at distance or licence-plate capture should consider higher-resolution alternatives. The 1/2.5” sensor size and H.264 compression balance storage efficiency with image quality for general monitoring. A micro SDHC card slot provides local recording redundancy when network storage is unavailable.

Questions about this item

How can I confirm the ZN-DT1A is recording at 720p after setup?

Check the live view on the PixelMaster NVR or web interface; the stream resolution should read 720p and the H.264 bitrate will be active.

What comes in the box with the ZN-DT1A and what must I buy separately?

The camera includes the 3.3-12mm varifocal lens and Micro SDHC slot; you must supply a Micro SDHC card, 12VDC/24VAC power supply or PoE switch, and cabling.

Which model should I choose among the VGA, 720p and 1080p versions?

Choose the 720p ZN-DT1A for HD resolution with H.264 dual streaming; select 1080p if you need full HD detail or VGA only for basic monitoring.
