Installing an intruder alarm will act as a major deterrent to thieves, prevent break-ins and give you peace of mind. CCTV is a popular choice of security system, especially with businesses and can provide video evidence of a crime. Intercom systems also help you monitor who has access to your home. Putting in security and fire doors will make your property safer too. At the very least everyone should have a smoke alarm in their home. Businesses and offices will often install fire sprinkler systems and fit extinguishers in case a fire breaks out.
