WatchLock™ has been developed to provide you with a product that both guards and reports. The ultimate gatekeeper: strong, elegant and hi-tech.

WatchLock™ combines Mul-T-Lock®’s high security padlock with an electronic alarm system. This is an intelligent integration of security with real-time alert tracking from anywhere in the world.

WatchLock™ is a standalone product that requires no external power source, making it the optimal solution for securing remote locations such as infrastructures, power and relay stations and anywhere a padlock would be used to secure valued items. Ideal for farms, warehouses and commercial properties. WatchLock™ secures your assets by reporting all open and closing events, enabling you to react immediately, wherever you are in the world.

WatchLock™ compliments an exisiting Mul-T-Lock® suited system reducing the need for multiple keys. WatchLock™ can also be suited in it’s own right, providing multiple access levels.
