The prints do not work!

Unable to record fingerprints, and when it works after 2 hours of testing, it does not work to open the gate because it does not recognize the registered fingerprint. Besides, contrary to what I was told there is no exit to open a gate automation but only one not supplied electric lock. So I had to buy a relay that turns it into dry contact 12V. Aillant bought 2 devices the concern really comes from the quality of the fingerprint scanner which is just a stew! The only interest to buy it (most expensive) is precisely the scanner. And suddenly having already paid for their facilities it cost more to make me uninstall and change. I'll also have to install a digital code (less secure) and it will still cost me money. I really regret this purchase, I recommend you then !!
