DO NOT BUY WITH EYEZON Purchased their UNO Panel, several accessories and the RF receiver. It simply doesnβt work with my DSC sensors even though itβs advertised to work. The 433Mhz DSC sensors work flawlessly with other systems including a Qolsys panel. After several months of trying to resolve this - Eyezon now want to charge me additional amounts to return the faulty items. Iβve asked so many times what other RF sensors I could try as I would buy them - that is simply ignored. AVOID this company and their panel, I feel ripped off and would choose another company and not be SCAMMED if I had the choice again.
