Most people accept the fact that criminals hate anything that makes them traceable, as it increases their risk of being called to account by the police and Courts.   The SmartWater Sprayer does just that, it makes criminals traceable, possibly for years, with over 95% of our customers saying that they have not suffered a burglary or robbery following the installation of a system*.

And that’s why we believe it to be the most powerful deterrent to crimes such as burglary, robbery or home invasion.

Each SmartWater Sprayer contains a unique forensic signature that is either activated automatically by the burglar alarm or, remotely, by the customer’s monitoring station. Although invisible to the naked eye, it glows bright yellow under a UV black light. SmartWater is tough and very difficult for the criminals to remove and the police only need a speck, the size of a grain of sand, to be able to prove the guilt of a suspect.  Frequently, it is the vital piece of evidence the police need to be able to arrest, prosecute and convict burglars, robbers or any other type of unauthorized intruder.

It simple terms, the criminal is literally carrying evidence on themselves that will prove their guilt, potentially for years – and that’s why they hate SmartWater Sprayer so much.

The following video, courtesy of ABC News, explains how both US and UK police have used the SmartWater Sprayer to arrest and convict criminals:

This system can be used in both commercial and residential premises to deter intruders.  Distinctive warning decals are placed around the premises to warn criminals that the systems are in use, acting as a powerful deterrent.

At this stage, the SmartWater Sprayer needs to be installed by an authorized alarm installer but they can be added to an existing alarm system relatively easily. The is an initial installation charge and then a annual maintenance fee or, if your system is being monitored, a small subscription charge to cover the cost of their staff activating the system on your behalf, if an intruder is detected.
More and more police/sheriff custody/booking offices are being equipped with SmartWater scanners, with suspects being routinely scanned.  The very act creates a powerful deterrent in the mind of the criminal as they know that there is little chance of escaping justice, wherever they go in the country.
