Q-How do DVR's work with motion sensing and cameras?

A: DVR's detect motion by looking at the video picture pixels. If the pixels change the DVR sees motion. DVR's have a "Mask" or over lay for each camera. you can define any part of the picture /video to trigger or not the recording. This allows a camera not to view normally moving objects Like tress or fans. Each camera also has motion sensitivity level setting this controls the amount of pixel change before the systems triggers the recording of the DVR. All motion sensing is done in the DVR software. the camera has nothing to do with motion sensing it just provides the video to the DVR because of this.

Q: How can I tell how long my DVR will record before the hard drive is full?

A: There are several factors that determine how many days of digital video a DVR will store. The Hardware configuration is engineered to continue recording after the hard drive is full. Once full, the DVR simply begins recording over the oldest video stored on the hard drive. The Frames per second setting controls the rate of recording, and quality of the image. At 30 fps, thirty digital "snapshots" are recorded per second. Cameras attached to the DVR will "share" the available frames per second. If you attach only one camera to a 30fps system, that camera will record at 30fps. Add a second camera to the DVR, and the two cameras share the 30fps and take 15fps apiece. Furthermore, a 30fps DVR with six cameras attached would allocate 5fps to each camera. The 30fps system will record 30 frames per second no matter how many cameras are attached. The amount of "snapshots" being stored per second directly determines how many days of video the DVR will store.

Motion Detection any camera into a motion detector. Since the DVR can record the cameras only when there is activity, the DVR saves storage space on the hard drive simply because there is less data to store.

Compression techniques save Hard Drive storage space. Video data takes up an enormous amount of hard drive space, so it must be compressed in order to reduce the size of the files and make it feasible to record and store large amounts of video data. JPEG compression best preserves the integrity of the video while reducing the file size slightly. H.263 compression decreases the file size exponentially, but it decreases video quality. Setting the record quality to 70% H.263 compression produces a fine video image and, at the same time, creates an acceptable file size. Setting primary cameras on JPEG compression and secondary cameras on H.263 will allow favorable video quality and help to save hard drive space.

Frame Resolution refers to the number of pixels in one frame of video. A standard frame resolution is 320x240, which produces roughly 76,800 parts of each snapshot. At 640x480 resolution, there are actually four times as many pixels being captured for each video frame. It means that the cameras set at 640x480 will write four times as much data to the hard drive as a camera that is set to 320x240

This forces the  computer to operate at higher speeds and eventually run out of resources. The net result is instability and system crashes. Most of our system is upgradable by changing the DVR Card only.
