Schools are often targeted by intruders during out of hours periods, such as weekends, nights, term holiday periods or other events that result in closures.  Many premises have hi-tech or high value equipment on site which they need to protect as well as deter anti-social behaviour that can result in criminal activity, theft, vandalism and in some cases even arson.
There are several security measures to consider to both deter and prevent incidents happening on school premises during out of hours periods.
