If you are going to be away from your home for some time one of the best things that you can do is to make your property appear to be occupied. Don't leave any clue that you are away.
Just before you leave for a vacation mow your lawn, and if possible arrange for a trusted neighbor to keep your grass trimmed while you are away.
Contact the post office and have them hold your mail while you are away. Cancel newspaper deliveries and have a neighbor regularly check your mailbox for flyers.
Tell trusted neighbors how long you will be away and to call the police if they notice anything suspicious. If possible arrange for someone to act as a house sitter if you're away from your home for a long time. (Ask them to take care of TRASH CANS)
The fencing around your home should be designed to prevent a thief from easily climbing over. An experienced determined thief would probably get over most fencing or walls but a good boundary can deter a casual thief. Walls, hedges or fencing however, should not be so high as to shield the burglar from view and allow him to work unseen.
Keep trees, plants and shrubs near doors and windows trimmed so burglars can't make use of the shadows. You might consider removing trees close to your home.
Fit motion-sensitive lights round your home, the movement sensors will ensure that an intruder is bathed in light if they approach your building. Remember that darkness is the thief's friend. Leave some lights turned on when you are out. An occupied home will usually have more than one light on, so to give the impression that someone is at home. Timer switches are an easy method of triggering one or more lights.
As daylight hours grow shorter in winter months, reset the timer to come on that much earlier. Timer systems can be set up to light different rooms at slightly different times each day. It is also a good idea to leave a radio on when you are out or connect a radio to a timer.
A security survey of your home can be performed by calling the Community Policing Unit @ 215 885-1600 ext 482 to make an appointment.
