The WT-9002 is a clever application of mobile phone technology which forms part of a gate automation system that allows you to open your gate with your mobile phone regardless of whether you are home of not.It has a wireless intercom in front of your that includes a speaker,a microphone and a 'Call' push button.When the 'Call' push button is pressed by a visitor,the system will call the owner's phone number automatically via the GSM/UMTS network allowing him to speak to the visitor in site of the location of the telephone being called.Communicate and allow entry from anywhere in the world as there is no limitation on the distance as to how far the system works.No longer let visitors realize you are out or away as every time the intercom button is pressed a call is made to your mobile.Should the visitor require access to your property when you are not there,opening the door or gates is a simple matter of adding a number into your phone.
