The new security alarm system provides an improved security alarm system through operation in disarmed, away armed, stay armed and alarm occurrence modes. The HLT (Homelive Technology Ltd) security system (HLT-SS) intelligently combines with CCTV(Closed-circuit television (CCTV) is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors) and appliances by the PLC (programmable logic controller) bus and communication bus. By adding a RJ45(RJ-45 connector are used to carry Ethernet signals )interface to the main console of a conventional alarm system, HLT-SS can increase the user's ability to monitor and detect intrusions remotely, and increase reliability by connecting the system to the internet. Internet and mobile phone alarm backup are provided in case of sabotage or failure in the telephone line. Connection to local and/or remote personal computer is also available. By using MICROCHIP PIC 18F97J60 as the main core MCU(Microcontroller Unit) of the security alarm system panel, the authorized user receives the alarm notifications by phone, mobile phone and/or computer in real time or substantially real time. The new security alarm system can protect authorized occupants' privacy even when using interior security monitoring devices. Additionally, the new security alarm system can activate communication devices (microphone/speaker) to allow authorized occupants to remotely communicate with an intruder. In order to prevent intrusion, the new security alarm system can be pre-programmed to turn on/off lights, TV, radio, Hi-Fi and other appliances, at random by simulating the occupants' daily habit through the PLC control bus as if there were people in the premises when the authorized occupants are away. More interfaces are reserved allowing expendability in the new alarm system.
