Burglar Alarms Guide - An Introduction
Burglar alarms are electronic alarms that alert you to intruders. They have sensors connected to the control unit by either an RF signal or low-voltage wiring which interacts with the response device. The most common types will indicate if a door or window is opened or if there is motion. There are also combination systems that will give you both fire and intruder protection.
Burglar alarms range from small noisemakers that are self-contained to complicated, multiple zone systems with computer monitors. There are two main types of burglar alarms: home alarm systems and industrial intrusion systems. They may be designed to detect, delay, or alarm, depending on the system. Delaying an intruder slows them down or detains them until help arrives, while alarms are meant to scare away the burglar as well as alert you to danger.
There are also home security systems that have a Security Camera. This lets you view what happens in your home when you are away, such as recording vandals or monitoring your child’s baby sitter. They can also be used as evidence if you are victim of a crime. You can also install a Dummy Camera to deter potential intruders who think you have a Home Security Camera installed.

Types of Indoor Alarms
Most home burglar alarms are meant for indoor use. Using them outdoors gives you more risk of false alarms and weather interference.
- Passive Infrared Detectors PIR: This is the most common burglar alarm for homes and small businesses. An Alarm Pir system is affordable and reliable. They are called passive alarms because they don’t need to generate their own energy. Infrared Motion Sensors determine when an infrared-emitting object is near by detecting changes in temperature. It then verifies whether the Intruder is actually there.
- Ultrasonic detectors: These Motion Activated Alarm systems transmit sound waves that are inaudible to the human ear. It detects intruders by locating a change in the sound wave frequency when an object is moved. This will trigger an alarm signal. This type of technology is generally considered obsolete and is no longer frequently used.
- Microwave detectors: These burglar alarms emit microwaves and detect reflected waves. They are usually combined with a PIR detector to prevent false alarms. The Motion Detector is activated when the microwaves change how they reflect back to the sensor.
- Photo-electric Beams: These systems are designed to detect intruders by transmitting red light beams. When the beams are obstructed, such as by an intruder, the alarm signal is activated. They are usually used in layers of two or more beams. If the intruder is aware of the system, however, they may be able to avoid the beams. You can find these systems in either indoor or outdoor models.
- Glass Break Detectors: These work using acoustic detection of the sound of glass breaking. They are mounted close to the glass panes so it can detect the sound frequency of breaking glass. There are also seismic glass break detectors that are installed directly on the pane, monitoring for shock wave frequencies.
- Magnetic Contact Door Alarm: These alarms are magnets installed on the door and the door frame. When the magnetic connection is broken because the door is opened, the alarm will sound.
- Some systems also have smoke, heat, or carbon monoxide detectors. These monitors are on 24 hours a day to protect you from these dangers, while the burglar alarm portion of the device can be turned on and off when you like.
Many homes and businesses are using a Camera Detector system for increased security. A Cctv Camera can record images for surveillance purposes, and they can be ether video or still cameras.
- The Micromark Cctv comes with a water resistant camera so it can be used indoors or out. Simply plug it into your TV, and when the PIR sensor detects movement, it automatically switches your TV to the camera’s channel. It features infrared LED lights to improve the night vision, and it has a moisture preventing system so the camera won’t mist over. The camera provides a high-quality black and white picture resolution. It has an anti-tamper system to alert you if the camera is disconnected, and a microphone lets you listen as well as view the images.
- A Pan Tilt Ip camera system lets you monitor any room using your PC. Up to 20 users can monitor the system remotely at the same time. The systems include a microphone to allow two-way communication. The cameras can pan 120 degrees and tilt 60 degrees to allow monitoring of a wide area.
- The Helix Portable Cctv Wireless camera system gives you instant connection of up to four camera. There is no wiring necessary, and the cameras can be moved at any time to give you more flexibility. The system can transmit sound and vision up to 100 metres, and the colour display screen is high resolution. It includes infrared LED lights for night vision. The system can be powered by battery or mains connections.
- A Spy Camera or Mini Security Camera lets you see what happens when you’re not home. This can be useful for intruders or monitoring pets or children. Some people use them as a ‘nanny cam’ to see how their nannies or babysitters behave with their children.
