Introducing "the new shape of security". With it's modern design and accurate detection system the VX Shield series is built on the foundations of Reliability, Convenience and Security.The VXS-RAM is a battery operated model featuring an active Infrared anti-masking, that detects covering, obstructing or spraying the lens surface and will notify the alarm panel or security system. Easy to install and set up The VX Shield series has been designed to make the installation phase as easy as possible for the installer. With every piece of the installation phase throughout with great precision from the easy 90 degrees rotation lock to open/close the cover to the easy to adjust detection area, we've made what was previously considered the most painful of tasks totally hassle free. The VX Shileld Series also includes an "Automatic Walk Test Mode" , when closing the cover the walk test mode expires automatically after 3 minutes. Intelligent analytics ALL VXS models are equipped with a digitally enhanced signal recognition logic called SMDA. By analyzing detection patterns and environmental information SMDA improves immunity against various noise factors such as climate changes and vegetation sways, and can distinguish between the cause of nuisance false alarms and genuine intrusions.
