The system has two primary functions depending on how it is designed, protect the life within the building, giving the occupants sufficient warning of an outbreak of fire, so they can evacuate safely and protect the building & its contents by summoning the fire brigade at the earliest opportunity.
Identifiers fire/smoke Alerts building occupants Sends signal to concerned authorities Automatically turn offs A.C.s/lifts
Automatic Sensors Smoke Detectors
Ionization Type Photoelectric Type
Heat Detectors Rate of Rise Fixed Temperature Detectors
CO Detectors Optical Beam Detectors Multi-criteria(smoke+heat)
Audible: Siren, Bells, Buzzer, Sounder Visible: Strobe lights, LED Auto dialers: Automatically dials stored

This is the component, thehub of the system monitorsinputs and system integrity, control outputs and relay information’s. The switches on control panel shown below consist of switches which are used to program the panel according to the needs
Secure life, property within any user defined premises. In today‘s world security is the primitive priority for your home. To stop unwanted intruders we just need an intrusion detection system.
Input Devices-Consists of different types sensors for input.
Control Panel-Consists of a controller which accepts feedback from a number of inputs and processes the accepted feedbacks.
Output Devices-Give the required output
Magnetic Contacts Glass Break Detector Multifunction Detector Motion Detector LPG Gas Detector Input from Tamper switches Smoke/Heat Detector Emergency Switches
Advantages of CCD Cameras:-•Very low minimum illumination performance (down to 0.1 lx at the object);• No geometrical distortions due to a precise two-dimensional construction;• Low power consumption;• No need for high voltage for beam acceleration;• Small size;• No influence of external EMFs; and, most importantly,• Unlimited lifetime of electrons generated by photo-effect.
In CCTV, as in broadcast TV, the majority of monitor display units are CRTs, which means they usecathode ray tube technology, designed to convert the electrical information contained in the videosignal into visual information
The liquid crystal display consists of a liquid suspension between two glass or plastic panels. Crystals in this suspension are naturally aligned parallel with one another, allowing light to pass through the panel. When electric current is applied, the crystals change orientation and block light instead of allowing it to pass through, turning the crystal region dark.
