As for the small equipment, they are mainly used for temporary security inspection, and they are characterized by their ease of moving and use.

On the other hand, the commonly used devices include several types including X-ray security inspection machine, metal detectors, hand-held metal detector, liquid detector and other systems and equipment.

For many organizations, security inspection devices are the firewall and first line of defense against external attacks. Security inspection devices help to report any potential danger, which reduces the chances of security problems that lead to catastrophic results.

There are a variety of security inspection devices, which differ in the way they operate according to their location and their primary purpose. However, the most prominent of these types are the following:

1. Equipment based on X-ray screening technology

This equipment is intended for the detection of containers, bags, or vehicles with X-rays. The XRAY works with the object imaging feature and its ability to penetrate solid objects, even iron, and it conforms to the latest international standards.

These devices also comply with all international and local safety standards and requirements to ensure that no trace of radiation is left on human bodies according to the authorized uses.

2. Narcotic drug testing equipment

Drug detection equipment is based on advanced technologies, enabling the worker to detect drugs quickly and accurately by wiping the surface of the substance to be tested.

This equipment helps to detect more than 10 types of narcotic drugs such as caffeine, ephedrine, and barbital. In the event that narcotic substances are detected, the alarm methods include a wireless alarm, in addition to a light alarm and an audible alarm.

3. Liquid inspection equipment

This equipment detects flammable, explosive, and corrosive hazardous liquids without opening the liquid package, effectively preventing items containing hazardous liquids from entering the safe area from the source. This equipment adopts a green design, as the detection method is environmentally safe and harmless to the human body and the detected object.

The liquid detection device can detect more than 30 different types of hazardous liquids, including flammable and corrosive liquids such as gasoline and hydrochloric acid.

There is a wide variety of security inspection devices, each of which is used in a specific place and for a specific purpose, the most prominent of which are the following:

• The American handheld detectors, which is widely used in all sectors.
• The Chinese handheld detectors that rotate 360 degrees.
• Handheld metal detectors.
• Walk through metal detectors.
• Walk through for the detection of contraband and metal objects.
• American walk through that is widely used in large places that need strict security.
