Total Pixels concerns the operation of a camera's CCD image sensor. This number measures the complete count of pixel elements on a camera's CCD image sensor. This number should not be confused with effective pixels, which can provide a more telling description of a camera's resolution.
Time lapse is a feature of most CCTV-industry VCR and DVR video recorders. Time lapse refers to recording one still video image (frame) at fewer than 30 frames per second. The speed of this recording can usually be adjusted. Time lapse video is therefore slower than real time recording and has a drag when the video is played back. One advantage of time lapse recording is the ability to increase maximum recording time so longer periods of time can be captured on a video tape or digital hard disk drive media. However, a major disadvantage of time lapse recording is missing many frames of video and missing much of what happens during a given period of time. There is no way to recover these missed frames on playback. For the ultimate in surveillance, real time video recorders deliver the most complete and accurate video information of what occurred.
