I've had electric gates for many years with an outdated intercom that would call me, but if I missed the call it would invariably lead to me missing the delivery or visitor. The new system calls all my family members simultaneously, with a video call where both sides can clearly see and hear each other...it's quite revolutionary really, I'm delighted. Then there's the car number plate recognition - something I now couldn't live without. Also the QR code feature is incredible. Very flexible. The whole experience working with the Securipad team so far has been second to none, highly recommend.
