Was a bit suspicious about the Plus system at first. Then, after reading, trying, and learning how it functions - it became clear that the system just works. But, anyone has to read the manuals. When all configurations are done - you can rest assured. The system will catch any little fucker who trespasses into your property. Day and night. Also, the data transport happens in the 2 to 68 MHz spectrum using your 230 V electric system. Thus not interfering either your other and perhaps older 433 MHz - or maybe your newer 868 MHz systems. A good system. I choose to trust it.
