Some of the wireless home security systems come with a feature of fire alarms. The sensors perceive any smoke in the premises and signal the control box to trigger the alarm. If programmed, it also calls the fire department for necessary measures. These are small as well as light in weight and therefore can be carried and installed onto to the walls of any part of the house. Some of these security systems may also be attached to video surveillance for live remote monitoring. On detecting any motion on the sensors attached to the camera the alarms immediately burst out.
