Packed with features, the SW316 is the most intelligent camera to date. Face detection allows the camera to adjust product focus to capture a person in shot and also use the XML data to trigger an alarm upon detection if using a compatible recorder. Auto back focus (ABF) allows easy installation, reducing installation time and ensuring perfect image. VIQS (variable image quality on specified area) is the latest innovation to the Smart HD range, allowing the camera to have higher resolution only on specified areas of the image, meaning lower bandwidth.
