What would you recommend installing to protect vulnerable glass perimeters – not only electronic solutions but physical solutions as well?

A: What you need to do is create doubt, and incorporate delays into any breach attempts, while a expediting rapid response. Look at some of the physical grille solutions – these will need to be custom-fitted. Framed aluminium or light steel grilles that either slide or unroll into a locking position could be installed if there’s budget.

If price and aesthetics are an issue, polymer glass films from companies like 3M are way less expensive. These are installed over glass surfaces and make them significantly harder to break. You should take these products seriously bearing in mind some are able to resist the impact of low calibre firearms. A serious attempt may lead to a breach, but it will take longer than 90 seconds, and there will be plenty of noise and vibration.

Add vibration sensors to glass windor frames so as soon as real force is applied to your glass or window frames an alarm will be activated. Your next line of defense, glass break sensors, will confirm to the monitoring station that this is a breach and requires the attendance of police, as well as security patrols. Installing a strobe directly above vulnerable glass that activates when a vibration alarm is activated is a clever strategy. If the glass is not close to the main strobe, add a second strobe on the same loop.

Layer your internal spaces with detection and medium security barriers. Smashing the windows might get thieves into the first layer but they’ll need to keep breaching defences to get further. All internal doors should be access controlled or locked with quality keyways – that means 5-pins or more – and these doors should be hardcore with 3 hinges, not 2. Choose hinges with locking tongues so doors can’t be levered upwards, pay attention to door frames and add wireless reeds to each door and PIRs to monitor internal thoroughfares and spaces.

Along with these measures, your electronic detection needs to occur as close to the perimeter as possible. External dual technology sensors can protect non-trafficked areas adjacent to glass. Your surveillance system should capture images from every vulnerable external point of the site. Think about lighting. You want anyone who attacks your premises to be visible to passing traffic and your cameras. Aggressive lighting will also make it harder for would-be intruders to ascertain whether there are staff still on the premises.

You should also ensure any site vulnerable to a breach includes video verification of alarm events, which guarantees a police response. While police don’t like wasting their time with false alarms, they will definitely attend if there’s a real chance of apprehension.
