Hard-wired systems are a good option if you are in the process of building your home. This is usually referred to as pre-wiring. Pre-wiring also includes installing additional outlets at strategic points for later use.
Hard-wired offer a wide range of sensors which are attached to a central console by wires and the entire home is secured through this central console.
Hard wired alarms are usually thought of as a more reliable alarm system. These are the traditional alarm system whereby the sensors that trigger the alarm are connected to the alarm control panel by cables. There is no chance for inference, unlike a wireless system, however there will be considerable disruption during the installation as walls will need to be channeled and shirting and floorboards lifted.
Advantages of Wired System Disadvantages of wired System
Installing a wired alarm system is that it generally requires less maintenance over time than a wireless system does. Because all the components are hard-wired into your home, there are no batteries to replace, which means the system is likely to be more reliable.
In addition, wired alarm systems are less prone to false alarms because they do not rely on radio waves. Therefore, hard-wired systems are less prone to the interference that often accompanies household wireless devices.
Wired systems also have fewer components, because each component in a wireless system requires both a transmitter and a receiver. Because of this, wired systems are less likely to fail.
The main disadvantages to installing a wired alarm system is the sheer amount of time and effort involved in installation. Because hard-wired systems require an electrician to run wires through all the walls in your home to connect protection points, installation is often much more costly and labor-intensive.
In addition, wired alarm systems are much less adaptable to home expansion, making it more difficult to add or modify components in the future.
Wired alarm systems are also non-portable for homeowners who wish to take their system with them if they decide to move to a different home.
Wireless Alarm System
A wireless alarm system is a home security package that again consists of a control panel and sensors, but are connected wirelessly thus virtually eliminating the need for wiring.
A wireless burglar alarm system can be self installed by the keen “Do-it-yourself” so will reduce the overall cost of your Security System significantly. It can also be easily de-installed and took with you if you move house so this is ideal if you are in rented accommodation.
A wireless burglar alarm is an excellent solution for homeowners who want the best of all worlds—easy installation, cost-effectiveness, and reliability.
All the sensors are connected wirelessly
Advantages of Wireless Disadvantages of Wireless
Battery Dependence :: Sophisticated burglars can disable a wired system by cutting the right wires. With wireless systems, there are no wires, so a burglar needs to disable each individual component.
Alerts :: Wired alarm systems have the capacity to alert the police or a security served. While some wireless alarms can dial 911 and play a recorded message, they mostly just make a loud noise.
Range::Wireless systems operate via radio signals, which means each component must be within range of the central station. For large houses, that may leave certain areas unsecured
Portability:: Wireless alarm systems don't need an elaborate set up. When you move, you can disconnect all the components very easily and take them with you.
Independence:: Wireless alarms are not connected to the power grid in your house. Batteries allow them to function even in the event of a blackout.
Anti- sabotage:: Sophisticated burglars can disable a wired system by cutting the right wires. With wireless systems, there are no wires, so a burglar needs to disable each individual component.
The basic form of a security system starts with a control panel that is operated by a keypad / remote key fob, usually located in a closet or basement.
The control panel can be called as the “brain" of the security system, and essentially operates as the central computer.
Various sensors connect to the control panel from locations throughout the home.
If the security system is armed and the sensors detect a problem, the desired result of an alarm system control panel is to cause an appropriate alarm output.
Door/Window Magnetic Sensor
This is usually accomplished with a non-contact switching system using a sintered alnico magnet and a reed switch.
The presence of the magnetic field passing through the conductors of the switch causes them to pull together, closing the circuit.
When the magnet is moved away from the switch, the circuit opens. Closed circuit indicates the closed door/window and releases the reed switch when the door/window is opened and triggers an alarm at the same time.
Installation method for Door/window sensor
Clean the surface of the mounting location.
Tear apart the double-side adhesive tape on the front of the magnet and adhere it to the appropriate position.
For steadier mounting, you may remove the plastic cover of the magnet and then drive two
If it is mounted on a metal door or window, and signal transmitting is not ideal, it is
Recommended that you underlay the magnet with something non-metal to improve the result.

PIR Motion Detectors
The Passive Infrared Detector works through detecting the human bodies‘ infrared spectrum.
The sensor receives infrared rays given off by the human body and outputs signals after computing to the central unit for further action to be taken.
This Technology detector combined with microwave and passive infrared intelligence, adopting advanced signal analysis technology, can avoid various kinds of false alarms under worse environment and proper installation can avoid dead zones.
Installation Method for PIR Motion Detector
Survey your home and determine where you intend to put a motion sensor.
Mount the sensor to a wall using the drill and screws. Remember to aim a passive infrared motion sensor away from a heat source.
Route the wire of the sensor (if it is a hard-wired sensor) along the baseboard and/or through walls to the control panel. PIR motion detector should be fixed min 6 – 8 Feet height.
Route the wire of the sensor (if it is a hard-wired sensor) along the baseboard and/or through walls to the control panel.
Connect the wire to the proper input. If you are using a wireless motion sensor, you may only have to route a wire infrared.
Vibration Detectors Vibration detectors fall into two main categories; 1.Detectors that mount on glass 2..Detectors that are frame / wall or ceiling mounted.
The glass mount type may be specifically tuned to the vibration of breaking glass or a basic vibration detector.
The units that are tuned to sense only breaking glass will not trip if someone simply knocks on the glass. The optimal mounting location for these detectors is in a corner approximately two inches from the frame. The reason for this is that the shock waves tend to concentrate in the corners. Basic vibration detectors will sense any vibration within their range.
The typical range of vibration detectors is a radius of 10 feet, although you should have one detector for each window unit being protected regardless of size .
Installation method for Vibration detectors
Vertically fix the vibration detector by screw on target. If somebody touch it, it will send the signal to the control unit for alarm.
Attach the mounting bracket to the surface with the screws. See "Tips" for seeking professional assistance.
Mount the rest of the detector into the bracket.
Glass Break Detector
The creative method used to protect glass required the use of a conductive metallic tape (also called as foil), directly to the glass.
The foil was varnished onto the glass 2-3 inches from the edge and glued around the perimeter of the glass.
If the glass was broken, the cracks would cause the foil to break. While this was a reliable method of detecting glass breakage, it was very labor-demanding to install and prone to extensive service from scratches and breaks in the foil.
Installation Method for Glass break sensor
Mount the sensor to the ceiling or wall in a location that allows it to cover all the windows.
Be certain that it is not mounted near insulation.
Use the drill and screws to secure it to its mount.
Route the wire from the sensor across the ceiling and down a corner to the base board.
Continue routing the wire along the base board and/or through walls to the control panel if you are using a hard wired version of the sensor. If you are using a wireless sensor, of course, there will be no wires to route.
Connect the wire to the proper input on the control panel.
