There are many organizations that use Security officers as a part of their overall security program. It is essential to have a good communication system in place to work effectively. These systems need to allow security officers to be notified when their help is needed, as well as this system should allow communications between security officers as they carry out their daily activities.

In big firms, there is generally some form that serves as the hub of the security operation. In these cases, calls for security service are generally made to the command center, which in return dispatches a security officer to the location where needed.

Smaller firms may not have a security command center and may only have one security officer on site at any one time. In such cases, employees generally communicate directly with the security officer who is on duty.

 Communications Options

Most general and easy methods of security, communications used now days are the cell Phone and the two-way radio.

In the past, pagers were commonly used but have now pagers have been mostly restated by cell phones.

There are security services company who provide good professional and well mannered security guards services. These security guards are being provided with all the new technology systems.

Two-way Radios

Businesses use these two-way radio systems. It’s used for public safety, and security communications for more than 50 years. Proceeding with the introduction of cell phones, two-way radios were the only option left when you want to make a two-way communication with someone.

Two-way radios consist of two parts, i.e. a radio transmitter, and a radio receiver. These two parts are joined into a single unit which is known as a radio “transceiver”. There are three types of radio transceivers: mobile Transceivers, portable transceivers, and base station transceivers.

Portable Transceivers

Portable transceivers are often called “walkie-talkies”, and these walkie-talkies are hand-held units. These walkie-talkies can be easily carried by the security officer. They are battery powered and have a self-contained speaker, antenna and microphone. External microphones and earphones are also supportive.

Portable transceivers generally have a range of between one and three miles depending on frequency, power and the type of obstructions between units.

Mobile Transceivers

Larger units that are designed to be mounted in vehicles are mobile transceivers. These systems have an external microphone that makes using the radio more convenient while driving. Mobile transceivers also have an external antenna that is usually mounted on the roof of the vehicle.

Cell Phones

 Cell phones were first introduced about 25 years ago. The time cell phones were invented they were expensive, bulky and would work only in selective limited areas. Now in this modernized age of technology, there are several cell phones in bulk variances, which are small, inexpensive comparatively and convenient to use. They are almost used by everybody in this growing and developing world. Small kids, youngsters, adults or old people everyone finds using a cell phone more convenient.

To provide good cell phone coverage within all areas of big buildings and complexes it is sometimes necessary to install distributed antenna systems similar to those used with two-way radio systems. The cost of installing these systems is sometimes subsidized by the cell phone carrier if the organization is a significant customer.
