The material looks promising on paper, but is not suitable for use in a remote gate. Pressing the door release button on the indoor console opens the spoil that hang 3 seconds, if more than 10m must be run. The use of the fingerprint as a means of opening requires pressing the doorbell, it wakes the whole house if you come back at night, or it must take a key with you, in this case the fingerprint reader does not really interest. My equipment had a glitch problem at the origin (system hang, requiring a reboot every 1 to 2 days) .After contacted the service, warranty return at my expense. After 7 weeks, still no news. I strongly regret my purchase I got a new equipment, more random problem, I am still unhappy with the use. I also noticed that the audio works only in one direction, from the outside to the inside, there is no way to communicate with the person who wants to enter. audio in this case is not used much. I'll try to find another intercom (a real, this time)
