Development of a Remote Controlled Alert System for Automobile Access into Premises

There have been various developments of security system such as computer security systems which prevent unauthorized access to personal files, but there is more to this. Security ensures that there is no damage to your data and that only authorized users can read your files. This work focuses on the dimension of remote controlled alert system for automobile access using password credential. This remote control alert was done by research on how remote controlled systems and automatic gates work and the transfer of frequency signals through transmitters to receiver module to be used at homes, schools, industries and companies. The remote alert system was developed by combining major systems: the power generation system or power source, transmission system, reception system (the alert system, the actuation system and the display system. Results showed that at smaller distance of 15 cm, the response time was 0.12s while at a longer distance of 100 cm; the response time was 15.91s. A valid signal was received on the receiver output display for automobile access into a premise; therefore TLP 315MHz RF transmitter and the RLP 315 MHz RF receiver can be used for a shorter distance.
