The WT-9003 is a simple system to allow remote control and also monitoring of isolated or unmanned sites and saves on any of attendance costs incurred for false alarms on systems.

Let your Mobile Phone be your Universal Remote Control. Forget the conventional remote control, you can now open your auto gate, garages, switch on the heater, thermostat, machines, air conditioner, computer servers with your Mobile Phone. Just 'speed-dial' a secure telephone number which identifies you as an Authorized User and the electric devices will turn on/ off. There are no call costs to use the as all incoming calls are rejected once authorized.

Save money on providing everybody with a remote control, let them use their mobile phone. Everybody has a mobile phone, let it be a universal remote control!

The system has a memory where the designated numbers are stored with a maximum of up to 250 numbers. When the WT-9003 receives a call, it will check the calling number and validate it with the listed numbers. If the number is in the list then it will reject the call and open the gate, switch on the boiler, turn on the heater, power up the motor and etc. The system does not answer the call, it simply checks the caller ID. Your network must send the caller ID otherwise the WT-9003 remote control will not work.

Usually operators don't charge until you answer the call, so it won't cost you anything to open the gate with the WT-9003. Of course, an active SIM is needed for this to be possible. To store a number, you simply send an SMS, that starts with a password to the WT-9003 GSM controller, indicating the phone number to enable its position in the list. Numbers are stored in the system's memory and not on the SIM. This prevents someone from removing the SIM to copy all the numbers into a mobile phone. Only the one who knows the password can insert or delete enabled phone numbers.

The WT-9003 GSM Switch doesn't have limitations like a normal remote control. Using a mobile phone you can open from very far away, even from another city! (International Roaming Required).It is really convenient to control your electric devices.
