Do CCTV cameras work during power cuts?

CCTV systems require electricity to operate. A UPS, inverter, or backup power system can help keep cameras and recording equipment running during power interruptions.

How long does a CCTV camera record?

Recording duration depends on the hard-drive capacity, number of cameras, resolution, frame rate, compression technology, and recording mode. Motion-based recording can increase available storage time.

Can CCTV cameras detect people and vehicles?

Many modern AI-enabled CCTV cameras can distinguish between people and vehicles, helping reduce unnecessary alerts caused by animals, moving trees, or other objects.

Can CCTV cameras detect a person entering a restricted area?

Yes. Compatible cameras and recorders can use intrusion detection, line-crossing, or area-based analytics to generate alerts when predefined rules are triggered.

Can CCTV cameras recognize faces?

Certain advanced CCTV systems support facial recognition or face detection. The availability and accuracy of the feature depend on the camera, recorder, software, installation, and environmental conditions.

Can CCTV cameras identify vehicle number plates?

Specialized ANPR/LPR cameras are designed to capture and recognize vehicle registration plates. Standard CCTV cameras may not provide reliable number-plate recognition.

What is a Wi-Fi CCTV camera?

A Wi-Fi CCTV camera transmits video over a wireless network instead of requiring a dedicated network cable for video transmission. It still requires power unless it is specifically designed as a battery-powered camera.

Are wired CCTV cameras better than Wi-Fi cameras?

Wired CCTV systems are generally preferred for permanent installations because they provide a stable connection and are suitable for larger surveillance systems. Wi-Fi cameras can be convenient for smaller or difficult-to-cable installations.

Description

What is a DFMD?

A Door Frame Metal Detector (DFMD), also known as a Walk-Through Metal Detector, is an electronic security system designed to detect metallic objects carried by a person as they pass through the door frame. From knives and firearms to other concealed metal items, DFMDs instantly alert security personnel, enabling quick and effective threat detection.

These systems provide fast, non-intrusive screening and are widely used to enhance security in high-footfall and sensitive locations.

Common Applications

Airports
Metro & Railway Stations
Government Buildings
Shopping Malls & Commercial Complexes
Events & Exhibition Centers
Educational Institutions

How It Works

A DFMD uses electromagnetic fields to detect metals:

Electromagnetic Pulse

When a person walks through the frame, low-frequency electromagnetic waves are emitted across multiple vertical detection zones.

Metal Detection

If a metallic object is present, it disturbs the field and triggers a signal within the internal circuits.

Alarm Activation

A visual and/or audible alarm is triggered, alerting security personnel for further inspection.

Types of Door Frame Metal Detectors

Single-Zone DFMD

Detects presence of metal in a single vertical zone
Basic security screening
Ideal for small venues or entry points with light footfall

Multi-Zone DFMD

Divides the detection area into multiple zones (6, 9, or more)
Pinpoints exact location of the metal on the body (left/right, upper/lower)
Suitable for high-security locations and busy entrances
