Do you set your house alarm at night?

Should you set your house alarm at night?
If you set your house alarm at night, it means you’d be alerted as soon as anyone gained entry through a door or a window. Your neighbours would also be alerted to your plight. A monitored alarm would automatically notify the alarm receiving centre who in turn contact key holders or police. A ringing alarm is often enough to send an intruder scarpering. The police agree that you should be setting your house alarm at night.“If you have a burglar alarm always remember to switch it on when you leave the house or when you go to bed”(West Yorkshire Police)
