6. Walkie talkie should be equipped for the following reasons:

1. In order to make contact convenient and fast, all security guards in a community or a building can use walkie talkie to contact in real time and report the situation
Second, you may ask, why don't you use mobile phones? Now that mobile phones are so popular, even farmers have them. Security guards are no exception. It's not as convenient and fast to use mobile phones? Ha, the landlord may only know one thing, but not the other. The walkie talkie doesn't need to pay the mobile phone fee, so the property company doesn't have to pay the security guards for the mobile phone fee (of course, it costs a fee when buying the walkie talkie, but compared with the service life of the property company for several years, the fee is very small); In addition, walkie talkies are faster to connect. Unlike mobile phones, they need to dial first, and then have to go through a network response time. If there is a major event in the community, it may lead to disaster. I once worked in a property company for a short time and used a talkie. The walkie talkie doesn't have this problem. Just press and hold the signal sending button on it, You can call the person you want to call directly at that time, which will not be as tedious as the mobile phone; Another problem is that the signal may not work when using the mobile phone, which is also very dangerous. The walkie talkie does not have this problem< Third, the walkie talkie has a disadvantage. The effective range of the walkie talkie signal is only about tens of meters (I can't remember the details, but it's usually not a problem to cover a community), so this is also the reason why the walkie talkie can't replace the common people's mobile phones

so you know, it is necessary for security guards to use walkie talkie, which is good for the interests of owners. It's not because they're police or not.

7. Police walkie talkie is designed for the public security, procuratorial, court, judicial, security, customs, military, armed police eight departments of wireless communication business contact walkie talkie
the working environment, use requirements, and the nature of its communication business of micro network communication are still different from other ordinary walkie talkies. In addition to good reliability and rability, the police walkie talkie of microgrid communication has powerful functions, superior performance, strong strength, shock resistance, anti-collision, lightweight, easy to use, large battery capacity and long standby time
police walkie talkie is convenient for coordination, and the full use of walkie talkie can avoid emergencies.

8. The use of walkie talkie is mainly one to many calls. It's very convenient to select groups. If there is a situation in one place, other people will know it, so it's very convenient to work. Just adjust the machine used by a group to a frequency
it's not only for public security, such as oil exploration, construction, factory scheling, etc
you can only listen when you don't hold down the call key. If you want to speak, you can hold down the call key so that people in a group can hear you
you can also talk alone, but you must agree to switch the same frequency The content of the intercom is not safe enough. In a certain range, as long as there is another intercom with the same frequency as you, you can hear your content)
the handset is the intercom! It's also called walkie talkie, ha ha
What's the use of mobile phone walkie talkie? My mobile phone is always in good condition
I bought my mobile phone from Longyun mobile network. It's brand new and original. It's of good quality and excellent quality!, The price is low, even! It's very enjoyable to use! I got the inspection from the exclusive shop. It's really 100% original and brand new. I suggest you go to Longyun mobile phone wholesale network to buy a mobile phone.

9. Traditional applications
walkie talkie is mainly used in the public security, civil aviation, transportation, water conservancy, railway, manufacturing, construction, service and other instries, which is used for the communication and command dispatching among group members, so as to improve the communication efficiency and the rapid response ability to deal with emergencies.

access control intercom
with the progress of science and technology, the intercom is more and more widely used in the security instry, and the access control intercom system is proced in this way. Access control intercom is the application of intercom in the access control system. Users can communicate through intercom or video. The access control intercom system is mainly composed of intercom host, intercom extension, UPS power supply, electric lock and door closer. According to the type, it can be divided into direct press, digital, digital door to door, direct press visual intercom, digital visual intercom, digital door to door visual intercom, etc.
intercom host
intercom host is the core control part of building intercom system, the transmission signal and electric lock control signal of each extension are controlled by the host, and its circuit board adopts vibration damping installation, And moisture-proof treatment, anti vibration moisture-proof ability is very strong, and with night lighting device, beautiful appearance, generous
intercom extension
intercom extension is a kind of intercom, which generally talks with the host computer. The intercom system for every household in the building forms an internal telephone system with the host computer, which can complete the telephone contact of each user in the system and is more convenient to use. It is divided into visual extension and non visual extension. With electric lock control function and monitoring function, it is generally installed at the door of the user's home, which is mainly convenient for residents to talk with visitors< The main function of UPS is to keep the building intercom system from power down. Normally, it is in the state of charging. When the power is cut off, UPS is in the state of supplying power to the system. Building intercom system, manufacturers generally do not use UPS battery, mainly because the power consumption of the visual system is too large, the general small capacity UPS battery can not guarantee the use time< Its internal structure is mainly composed of electromagnetic mechanism. As long as the user presses the electric lock key on the extension, the electromagnetic coil can be energized, so that the electromagnetic mechanism drives the connecting rod to act, and the door can be controlled to open. It is a special linkage mechanism of automatic door closing. It has a regulator, which can adjust the acceleration and the force of action. It is convenient and flexible to use
working principle
visitors can call residents and talk with them conveniently through the host in front of the unit door downstairs. The residents control the opening and closing of the unit door indoors, and the host of the community can receive the alarm signal from the residents at any time and send it to the host on ty to inform the security personnel of the community. The system not only enhances the security work of high-rise residential buildings, but also greatly facilitates the residents, Rece a lot of unnecessary upstairs and downstairs trouble
working mode
the door of the building is always in a locked state at ordinary times to prevent non building personnel from entering the building without permission, and the residents in the building can freely enter and leave the building with the key. When a guest comes to visit, the guest should press the room number of the resident to be visited on the intercom host keyboard outside the building and call the intercom extension of the resident to be visited. The host of the household to be interviewed can make two-way or visual communication with the visitor through the intercom equipment, and confirm the identity of the visitor through the voice or image of the visitor. After confirming that visitors can be allowed to enter, the owner of the resident controls the electronic door lock on the entrance door of the building to open by using the unlock button on the intercom extension, so that visitors can enter the building. When visitors enter the building, the door will be locked automatically
the Security Department of residential property management can monitor the working condition of the security intercom system of each residential building through the security intercom management host. If the entrance door of a residential building is opened illegally and the security intercom host or line fails, the security intercom management host of the community will send an alarm signal and display the content and location of the alarm. The system can be used to communicate with each other between estate management department and residents or between residents and residents. For example, the property department informs the residents to pay various fees, the residents inform the property management department to repair the residential facilities, and the residents report to the management personnel or the neighborhood for help in case of emergency.
