* Don't advertise new projector installations and don't display packaging after installation

* Make sure your premises are alarmed

* If the school is small and is surrounded by houses try a Neighbourhood Watch scheme

* Marking your projector with labels might be cheap, but it's not effective

* Alarms, when linked to a main alarm system, are good deterrents.But response times are crucial

* Battery-operated individual alarms rely on response and are only effective when the building is manned

* Cable systems are a good visible deterrent, but they can be removed with minimum damage by thieves

* Heavy duty cable systems (10mm plus) are a very good visible deterrent, they're hard to cut and work best with an alarm, But padlocks can be overcome

* Security enclosures acting as a support (no ceiling mounting cradle required), are highly visible, very resistant and difficult to overcome Source: Dalen
