Near radio channel (up to 500 m)

Radio channel systems for close-range communication are used for security and alarm setups within 500 meters. Devices like BN-L-33, Leader, and ACS-102 provide reliable wireless links for remote control and monitoring. These systems are suitable for various applications, including security gates, alarm panels, and access points.

Many models such as Sputnik-2, TR-500F, and TxRC12 are designed to operate in environments where wired connections are impractical. They feature simple installation and stable signal transmission. Whether for industrial or commercial use, these radio channels help maintain effective control over security systems without the need for extensive cabling.
