We are the Western Washington SmokeCloak dealer and installer. This product is a must-have for businesses that can suffer large value losses in a fast grab during unauthorized entry. The device comes in 3 sizes for handling a small storefront to a large warehouse. SmokeCloak will release a fog that will fill a protected area in 15-30 seconds. Upon activation, the uninvited visitors will have no choice but to retreat immediately. The fog will dissipate in about one hour without ventilation, and about a half-hour if ventilated. The patented fog is harmless to humans or pets and leaves no residue to clean up. We have found this product to be a premier security option in conjunction with a security alarm and it will likely pay for itself after the first attempted burglary. Call Absolute Security Alarms at 206-257-1951 for more information or a demonstration of this game-changing security device.
