Hi, I’m a security systems development manager, I’m researching the market and bringing new products to the market. I will always be happy to help you when choosing home protection. Come in https://wrsecurity.co.uk . As experience shows, the bars on the windows, armored doors and tricky locks are not able to protect against intruders. The police and security firms are advised to strengthen the protection with an alarm. This simple solution makes many thieves abandon robbery attempts. And if you connect the alarm to the security console, then many villains will not even want to look towards your door. PRO-level wireless solutions have evolved, becoming a serious competitor to wired systems. Today, wireless alarms provide more information, are easily installed and are not limited to security functions. They are more expensive than wired systems, which is offset by ease of use and the availability of great opportunities. Pay attention to the range of the system. Manufacturers often indicate numbers in open areas. Indoors, indicators depend on the materials of which the walls and floors are made. Therefore, the longer the range, the better. For example, in the Ajax system, the sensors can operate at a distance of up to 2000 meters from the control panel. This is an indicator in open space. Indoors, this is enough to cover the 3-4 floors. In addition to security functions, the system should be able to protect itself. For this, development companies equip their products with additional levels of protection. Encryption. The radio signal between the sensors and the control panel must be encrypted and protected from forgery. This will avoid intercepting the signal and replacing equipment. It is better if it is a complex AES-algorithm, to which there is no code grabber, and not a standard cipher, such as KeeLoq, hacked long ago. Reservation channel. For a wireless system to work, you need a clean radio channel.
