Walkie talkies are extremely useful pieces of equipment. Long distance communication is very effective at managing the security of a premises.

A group of security guards armed with walkie talkies are much more effective than a group without. Efficient communication between several guards for example increases their ability to maintain a secure perimeter. This is because the guards can co-ordinate themselves more effectively, improving the area over which security is maintained.

In the event a guard is attacked or runs into some other kind of trouble, his ability to communicate with his teammates may mean the difference between catching a criminal, or suffering the loss of assets and even injury to the guard.

This is especially important during the night. The premises will be shut-down, typically with nobody else present except the criminal and guards. So no help will be immediately available to them, they will need to look after themselves for at least the time it takes for the police to arrive.
