Hand-held metal body search detectors are used to detect metals in the body of people at security checkpoints. Hand-held metal search detectors are often used by security guards along with walk-through metal detectors.

A walkie-talkie is a two-way radio, which means that unlike a normal radio, it can both send and receive information. As the same channel is used for both functions, this means only one person can talk at a time.

Archway Metal Detector Gate represents the pinnacle of security technology. It employs state-of-the-art electromagnetic fields to detect even the smallest traces of metal on an individual. This advanced technology ensures that no potential threats go unnoticed.

The Under-Vehicle Search Mirror is a wide-angle illuminated convex mirror mounted on castor wheels which is used for searching the underside of vehicles. The unit has a long handle, with a non-slip grip, which swings down to the horizontal for maximum reach under vehicles.

The Traffic Signal lights work on simple timers. Depending upon traffic levels at a particular intersection.

A digital video recorder (DVR) is a device that converts the signals from an analog camera into a viewable digital format that can be stored on a hard drive. It's one of two local storage options for closed-circuit television (CCTV) security systems—the second being network video recorders (NVRs).

Access control devices are security systems that restrict access to a building, room, office or area by requiring a valid credential such as a card, PIN code, or biometric data. They provide a higher level of security than traditional locks and keys, as they can't be easily duplicated or bypassed.

Alarm systems are designed in such a way that they can detect any problems such as fire, gas, invasion, or any change in the environment. They'll figure out the changes and determine if the event is threatening, then they'll send you a notification about the situation.

Fire-fighting equipment should be considered as a means of both prevention and protection. For example, portable fire-fighting equipment can prevent a small fire growing out of control and spreading beyond the area of origin, affecting the means of escape and posing a risk to relevant persons.
