A self contained intruder alarm can be fitted to an external door and is set off when the door is opened.
The system is battery operated so you will need to change these every so often.
A self contained intruder alarm is turned off with a push code that can be determined by yourself or by a key. The system incorporates a delay switch which allows several seconds to enter or leave without triggering the alarm system.
A wireless home alarm system has the main advantage of doing away with the need to run cables around your house.
Passive infra red sensors and magnetic door contacts are independently battery powered and transmit a radio signal to a control unit when movement is sensed. This in turn triggers the alarm.
A wireless home alarm system can be set using a remote key fob switch which can also work as a mobile panic alarm.
As there are no cables to install, the whole set up process is easier and quicker to install.
Higher grade systems tend to offer a repeater unit which increases the transmission range so that outbuildings may also be protected.
The only disadvantage of the wireless home alarm system is that you must replace the batteries in the sensors. Not ideal…

Your typical French doors are of a timber framed construction. You can install rack bolts inside the doors which rise up into the frame at the top and down into the sill or floor at the bottom. It is important that bolts are fitted on the overlapping door.
If you want added piece of mind, also install some hinge bolts.
For metal doors you should fit surface mounted self locking bolts.

Sashlock’s combine both a latch and bolt with handles on either side of the door. This type of lock is usually seen on back doors.
A sashlock usually incorporates three levers - which is not ideal for security. However, this can be replaced with an upgrader unit which includes five levers and a deadlocking action.
Having the deadlocking facility is pretty important on back doors as they are often glazed and in isolated locations. This makes them the target of choice for burglars.

Usual security measures for patio doors comprise a small lock mounted on the inside door - the bolt then fits into a hole with the other door.
These kind of locks can be fitted to metal framed doors or timber doors. You will of course need appropriate screws for each door material type.
For increased security fit locks to both the top and bottom of the door.
