Clean Image

1)The DVR unit is capable of recording video using one of three different resolutions. When using the 720 x 480 resolution, two fields are mixed. Because of the timing gap between the two fields, according to the standardized image rules, a little afterimage might occur to high speed moving images. The Surveillix™ DVR unit allows you to remove this by pressing the CLEAN IMAGE button.

5.5Search Options Overview

The Search Options allow you to find what you want quickly, enhance the image quality, and export the video or images in a number of ways.

Index Search – This option allows you to perform a search based on Motion detection, Sensor activation, and Instant Recordings. This search allows you to quickly narrow down large amounts of recorded video based on that criterion.

Preview Search – The Preview search is a Search option that allows you to narrow down recorded video in a 24 Hour period. It breaks down a single day into 24 images, one image for each hour of the day (The images are taken from the first second of each hour). When an image is selected, the ‘hour’ chosen is then broken down into 6 images, one image for every 10 minute increment. Finally when another image is selected, 10 images are displayed, one for every minute within the 10 minute period. From this point, the selected image can be applied to the Main Search.

Object Search – The Object Search allows you to specify a region on an image and perform a search based on any motion that has occurred within that region.

Graphic Search – The Graphic Search displays recorded video in a color coded format that allows you to easily select the portion of video you wish to play.
