The difference between a professional security system and a cheap alarm system
When you decide to protect your apartment, house or office, you will have to make a decision, use a professional security system or rely on an uncertified and slightly cheaper alarm system. Without going into details, it seems that the differences are insignificant and that any security team will be able to cope with the task successfully.
A slight initial saving can lead to false alarms or, even worse, not responding to a real threat. It could stop working without warning or notification. The communication range of the radio signal is barely enough to protect the room, and the connection is constantly interrupted. The app does not work correctly. Your room (eg your home or even people's lives) is left completely unprotected from attack by intruders. Also, the security companies refuse to connect the security system to the Alarm Receiving Center, and the answers to the alarms fall on their shoulders.
To help you make the right decision, we have put together 6 essential requirements for a reliable security system.
1. The security system must use multiple channels to communicate with the outside, GSM, GPRS, Ethernet, WiFi...
2. The security system must use a cloud server, it represents a link between the control panel and the security system management application. It allows the owner to control all aspects of operation through the internet. A professional system takes advantage of this connection to monitor the connection and its correct operation.
3. Security devices must use reliable communication technology to communicate with the control panel. The communication between the control panel and the detector must be extremely reliable if it is through radio frequency. A professional system also usually uses various radio frequencies within a range up to 868 MHz.
4. Avoid WiFi communication with the control panel, the bands used by a WiFi network (2.4 and 5 GHz) are usually very crowded, so they do not guarantee good communication and stability, an ethernet connection is recommended.
5. Communication between security system devices must be bidirectional (duplex). Detectors and control panel transmit and exchange information, thus avoiding connection failures or loss of information in the event of, for example, a short jump.
6. The security system must encrypt the information and have anti-sabotage protection. In this way, the neutralization of the control panel is avoided, since the assailants could take absolute control of the security system. In turn, the level of encryption must be complex, since the more primitive the encryption, the easier it will be to hack the system.
