Very brilliant with tamper alarm button on the back and easy to operate with product instruction,especially the LCD screen indication,I can read and confirm my order clearly.Very good.
It comes as described.Easy to remote control/manage by mobile APP. Wired&wireless connaction allowed,very humanized design.
The defense name can be editable as you wish such as SOS/fire/gas/door/hall/window/balcony,etc. Once any one of them is trigerred,you can get the exact places alarm message then.
Great design with backlight keypad,easy to operate at night.
I can see the intensity of signal directly from the LCD screen to adjust the installation place.That helps me a lot to assure it's working better.
