One gets the feeling of being watched upon entering Sharp Vision USA — and that's the way it's meant to be. Sharp Vision specializes in security systems, and the right-hand wall of its showroom displays numerous cameras and monitoring systems. In addition to cameras, Sharp Vision stocks DVRs, power supplies, cables, wires and connectors — all of the elements necessary to create a comprehensive security setup. Sharp Vision also installs security systems and offers troubleshooting and repair as well. Beyond technology-based systems, Sharp Vision can arrange for so-called "standing security," that is, human security guards. An appointment is not necessary; Sharp Vision will know you're coming.
