Lighting
Burglars do not want to be disturbed. You can convince them that someone is at home by having plug-in timer controls for lamps. Technology has now made it even easier with the invention of cotton bobbin sized gadgets that fit between the bulb and the light socket. These automatically switch on the light as programmed.
Don’t just have the hall light switched on when you’re not in; have the lights switching themselves on in the bedroom, bathroom (not many people get out of the bath to answer the door), kitchen and lounge.
Internal Sounds
A plug-in timer for the radio would provide sounds from the living room. It is better to tune the radio to a station which has more talking than music.
Curtains
Curtains can now be opened and closed electronically, although it is quite expensive.
As an alternative, you can arrange for your curtains to be closed in your absence by giving a trusted neighbour a key. Most neighbours don't mind the little trouble, as you may be doing the same for them soon.
If curtains are not going to be drawn while you are out, use timer switches on low table lamps around the room, instead of the main ceiling light.
Set the lighting timers to come on when it goes dark, especially if you tend to be late home in Winter.
