The most important thing to a person committing a crime is not being caught. CCTV is a major deterrent as it means that not only does the criminal have to contend with the crime but they must now also disguise themselves. This often makes them stand out before the crime has been attempted.
With the latest forms of detection we can detect and record criminals before they have attempted a break-in or theft. When these systems are remotely monitored we can then either call the police or guarding service, or use a public address system to warn them off.
In recent years the quality of recordings has increased dramatically. This is mainly due to the use of digital technology within the CCTV industry, providing better pictures at a dramatically reduced cost which has made the systems so affordable that they are fitted not just to high risk businesses but to homes as well.
A small domestic system will allow you to view around your house from your television as well as to review recordings of previous day's activity from your computer. You can if you wish even access the system from any internet point in the world or from your smart phone!
