Reliable without false alarms! The downside I would mention is that it does not include the GSM card, which costs as much as the entire basic kit. Since the GSM is a necessary evil to know which contact triggered the alarm! Other than that, it seems like a serious system that will last for many years. For those who say the support is nonexistent, I believe they didn't even bother to send at least one email, as when I needed something, the technician even sent me his personal phone number to contact him for any questions!

Quite a good system with settings for beginner users. Easy installation. Without complicated settings unlike others where you get lost. Minus the expensive accessories.

It is easy to install, configure, and allows for expansion and addition of other devices (fire alarm, indoor siren, indoor alarm light). From the power supply line, I power cameras (without the need for UPS) and its own fire detection system. The service, when support was needed from the company (Olympia Electronics), was immediate via email and beyond expectations. I have no false alarms. Both the materials and the construction are very high quality and well-made. It is slightly behind technologically, for example, it does not have WiFi, mobile control, but in such cases, reliability and value for money are the most important factors.

Zero support, programming at the limits of "linear B" and only from the panel or from a computer with XP (we are in 2020!), unacceptable user manual. I regret buying it! Definitely worth someone to pay double the money for something more decent!

For obvious extra capabilities only with expensive paid accessories and hard-to-find support! Stay away!!!
