This study aimed to develop a system that can provide security on home through the integration of different security devices. The study sought to determine the following: (a) the features of the security system, (b) efficiency of the security devices used in the system in terms of its inputs, namely, biometrics fingerprint scanner, human motion sensor and keypad, as well as to determine the response of its output, namely, GSM, intrusion alarm, and LCD. A two-phase method was employed in this study to assess the reliability of the developed system, namely, the experimental development and descriptive method. There are thirteen purposively chosen evaluators of this study which are composed of three home security experts, five engineers, five selected students and residents. The implemented system was evaluated and the system features enumerated was found to be effective. Biometric fingerprint scanner read the fingerprint accurately. Human motion sensor was able to detect human presence. Keypad could activate and deactivate the security system and worked accurately in terms of password recognition. GSM was able to send a text message to the homeowner. Intrusion alarm gave a warning when the sensor detects human presence. LCD displayed the status of the system. Through the integration of various security devices better security assurance can be achieved.
