Inmate/Crowd Control

The YardGuard is a second-generation water restraint system with self-contained and modular dynamic chemical injection control. The system, which is designed to be simple to maintain and install, provides fast target acquisition and crowd control. The unit is manufactured, preassembled, and tested at the Hydro Force Factory.

YardGuard can be installed on an institution’s concrete mounting pad. As an option, the unit’s water cannon can be remotely mounted and connected with a prefabricated piping assembly. Multiple nozzles with multiple control points are also an option.

The YardGuard system uses a direct injection system rather than a high-pressure air system. All chemicals are stored at atmospheric pressure and the control system uses pressure information to adjust the chemical injection. Real-time chemical test data is presented on the video monitor and VCR following each chemical injection operation.
