What is a visual sensor?

Generally, sensors are simple devices designed to accomplish a single purpose. Contacts, vibration, and temperature sensors all monitor status conditions, and output alarms if that status changes.
A visual sensor is a simple device as well. It utilizes low-cost, fixed use components (lens, processor board) to accomplish a single task: reliable intrusion detection and visual notification (up to 200 feet). In order to be effective as a physical security device, the sensor also needs to filter out the illumination and weather changes which typically cause numerous false alerts. Advanced, proprietary algorithms perform this function on-board. These complex yet extremely efficient algorithms are the heart of the Emza advantage.
Once an intrusion is detected, live event images (JPEGs) are transmitted by the sensor’s built-in RJ45 or WiFi network interface, through the local ECU unit, to either local security or a remote Monitoring Station via an IP network – even if it is a low-bandwidth or a cellular network.
Combining this advanced functionality into a small outdoor (IP66) package requiring zero configuration allows visual sensors to be deployed and operated by electricians or other general technicians for low cost.
Emza’s WiseEye represents the world’s first visual sensor for security applications.
