Perimeter Alarm System

If a intruder breaks into a house while the residents are at home, the worst fear is of the safety of the family members. Perimeter alarm system would prevent any intruder from entering your home as it triggers the alarm while the intruder is still outside and trying to break in. These systems detect high frequency vibrations which are caused due to forced entry.

Home Alarm System

Unlike perimeter alarm systems, Home alarm system detects the internal movements inside your home when you are away. It functions using infrared sensors to detect motion which lets you know about any security risk when you are not at home.

Other security devices that can be installed along with motion detectors are CCTV cameras, door contacts and window break sensors. We provide pet friendly detectors which are able to differentiate the difference between a pet and an intruder and reduces the risk of false alarms.

The home alarm system can be set to standby mode when you are at home, without switching off the alarm system. When going out, remember to switch the alarm system to standard mode which would arm the system.

Not only at businesses places, but these system are being installed at homes because of their multiple benefits.

If you have pets at home, it may so happen quite frequently that your pet tripped the alarm system. Therefore, install a pet friendly system which can easily identify the difference between your pet and an intruder and can reduce the risk of false alarms. Passive Infrared detectors or PIR detectors are able to distinguish between humans and animals due to the difference in shape and size of the and it in turn allows your pets to move freely inside the house or in the property.

Depending on the size of your pet, we can suggest you the type of pet friendly sensor that would serve your purpose. If you a have a small dog or a cat, a normal motion detector can also be installed upside down, about four feet above the ground. The range of a normal motion detector goes straight and then down which can detect humans, but if installed upside down, it goes straight and then up which cannot detect small pets.

A working of a pet friendly detector depends on a few factors like the difference in height of a pet and humans. As humans are taller, they have a higher coverage area as compared to pets which are generally smaller in height. The sensitivity of the sensor can be calibrated to ignore particular sizes and shapes and can be adjusted as per height so that your dog can pass underneath the motion sensors without triggering the alarm.

Dual alarms are also available which has two separate sensors and they trigger the alarm only when both the sensors detect the motion


The wireless door / window sensor triggers the alarm by wirelessly sending the signal to the alarm system, when a door or window is opened. The wireless sensor can also show the current status of the door/window. When at home, the alarm will remain deactivated, but make sure to activate the alarm before leaving home so that you are alerted if a window or door is open or in case of an intrusion.

The wireless door / window sensor can be placed on all exterior doors and windows and specially the ones which are at the ground level. These sensors also prove helpful if you have small children.


A glass break sensor activates the alarm system when a glass pane is shattered or broken. These sensors use a microphone which monitors any sound or vibration coming from the glass and if the vibrations exceed the set threshold, the alarm system gets activated.

These sensors are best to be used on glass doors and windows or commercial stores which have a glass front. It is an extra layer of protection for your home and can scare off an intruder easily. Depending on the size of the room, one glass break sensor can also cover all the glass doors and windows.


Wireless alarm systems are easier to install at homes and properties and are cost effective as there are no wirings that has to be done. The devices are installed and connected to an existing power point and a back-up battery.

If the distance between the detector and the control panel is more, no worries because wireless repeaters are also used along with the system which ensures that the signal is received the control panel. To know more about wireless alarm systems, Click Here
