It would seem that with the abundance of such compact and convenient gadgets such as cell phones, smartphones and other tablets, walkie-talkies should not be used so often. But in fact, security companies, regardless of its size and the area of the protected object prefer to use compact PMR or LPD radios.
And this is correct, because in the real business of the security company there is no phone call. Imagine the situation when the security manager has to urgently report important information to several posts. How will he do it? Send out a text message to everyone or call each post. By the time everyone is called, the information that needs to be transferred will no longer be relevant. What if, God forbid, the cellular network goes down temporarily? Collapse?
With walkie-talkies there will be no such problems. And the whole transmission of information takes minimum time – press on the tangent and send over the air all that is required. And depending on the task the information is transmitted to all subscribers or only those for whom the information is intended.
Walkie-talkies for security companies primarily need to have the necessary level of durability, to withstand shocks, falls, exposure to moisture.
Walkie-talkies for security: what are they?
This type of professional equipment includes dozens of varieties, not to mention the existence of complex solutions and individual configurations. According to the type of performance, all radios for security can be divided into three groups:
portable (portable) – compact models with high-capacity batteries;
Stationary and vehicular (more powerful radios with a preferential range);
basic equipment (repeaters, warning systems and dispatching).
The classification also affects the technological component, based on analog or digital format. The type of signal largely determines the functionality and specifics of the application. If in one case, the introduction of advanced digital radios will be preferred, in the other – no. Analog models with powerful repeaters are excellent for working in terrain with a large difference in altitude, as well as in urban areas and various buildings and structures where security measures are necessary. To create a stable network in such conditions, it is sufficient to install one or more specialized antennas.
Separate attention should be paid to such a device as repeater, which can increase the range of radio stations by several times and increase the functionality of the communication system. They are successfully used both with digital and analog models, depending on the specifics of the security company and the configuration of the object. In this case, the use of security radios without repeaters can significantly reduce the cost of the project. What radio communication system to choose? Reliable answer can be given only by professionals. This question should be considered comprehensively, including taking into account the financial capabilities of the security agency.
