If there is a drop in voltage in this circuit, the brain knows that someone has interfered with the electrical system. When this current flows, it causes the brain to sound the alarm.Īs an overall protective measure, modern alarm systems typically monitor the voltage in the car's entire electrical circuit. With the new wires in place, opening the door (closing the switch) sends an electrical current to the brain in addition to the inside lights.
In the following sections, we'll look at a variety of sensors to see how they work and how they are connected to the alarm system's brain.Īll you have to do to set up door sensors is add a new element to this pre-wired circuit. Since cutting the power is a possible indication of an intruder, it triggers the brain to sound the alarm. This hidden battery kicks in when somebody cuts off the main power source (by clipping the battery cables, for example). The brain and alarm features may be wired to the car's main battery, but they usually have a backup power source as well. Security systems differ mainly in which sensors are used and how the various devices are wired into the brain. The brain's job is to close the switches that activate alarm devices - your horn, headlights or an installed siren - when certain switches that power sensing devices are opened or closed. The brain in most advanced systems is actually a small computer. A computer control unit that monitors everything and sounds the alarm - the "brain" of the system.An auxiliary battery so that the alarm can operate even if the main battery gets disconnected.A radio receiver to allow wireless control from a key fob.A siren, often able to create a variety of sounds so that you can pick a distinct sound for your car.An array of sensors that can include switches, pressure sensors and motion detectors.It also places control of your home or business security firmly in your hands through your mobile phone, as it will receive instant notifications of activity on your alarm system whether you may be at home, work or out playing. We can then activate a range of emergency responses, from our own armed response officers in our operational areas, to ambulance services, the SAPS and roadside assistance services.īut our app is more than just a panic alert button. Our state-of-the-art control centre receives the signal and makes contact with you to determine the type of emergency. Our Blue Security Mobile App, when installed on your smartphone, pinpoints your precise location – whether you are at the beach, out jogging, or hiking in a park – the moment you activate it in an emergency. We at Blue Security have a vision to create a safer city, and have developed an innovative solution – the Blue Security Mobile App – which will give you peace of mind knowing that help is always just It’s a reality that can lead us to live in fear and seek solutions that make us feel safe again. Durban’s parks, playgrounds and promenades make it a pleasant place to live, work and play but whether we’re commuting to work or enjoying the great outdoors, our peaceful lifestyle is threatenedīy criminals who cruise our suburbs seeking to pounce on their next vulnerable victim.
