Specifications vary significantly between manufacturers and models. For example, one Chennai-listed system specifies a 6-zone configuration, 700 mm passage width, 2000 mm detection height and 230V AC supply, while another Chennai supplier lists 6- and 9-zone systems with 90–240V input and adjustable sensitivity.
A single-zone DFMD is a cost-effective option for basic security screening applications.
Multi-zone systems provide more precise detection-area information and are useful where enhanced security screening is required.
Portable or detachable models can be useful for temporary events and locations where the security checkpoint needs to be relocated.
High-sensitivity models are designed for applications requiring more detailed detection of smaller metallic objects.
When selecting a supplier, consider the number of detection zones, sensitivity adjustment, passage dimensions, alarm system, display, construction quality, power requirements, installation support and warranty.
For high-traffic facilities, multi-zone systems may be preferable because they provide more detailed detection information. For smaller offices or basic entry screening, a single-zone model may be sufficient.
Installation and calibration are also important. The detector should be positioned to minimize interference from nearby electrical equipment and large metallic structures. Supplier support for installation, sensitivity calibration, troubleshooting and annual maintenance can help maintain reliable performance.
