CCTV Video Q and A's
How to set up home cctv system?

hi I would like to know how to set up a home cctv system. I have a micromark multi camera controller system. Modem number MM23190
Now, I have 2 cameras plugged in and I have a small tv, where I can watch the video coverage of what my cameras retrieve, however, what I would like to do, is to be able to record, nd playback anything that my cameras retrieve, for evidence purposes.

You have chosen the wrong equipment for this, it is very poor quality and does not provide common interfaces. The only option is to connect it to a standard Video recorder. It is not going to give enough quality for evidence in court.

CCTV Video Articles and News

DVR stands for Digitals Video Recorder. Advantage of using a DVR technology over analog recording is that the Digital Data recorded by DVR can be compressed and saved in special hard disk and can be reviewed later. Video compression plays an important role in overall operation, properly compressed video can also save disk space.
All DVRs use some kind of compression algorithm called a codec to keep the digital video files at a manageable size. The average size of an uncompressed still image frame at 320x240 resolution in 24-bit true color is about 230400 Byte or 2.3 Mega Byte. Same image frame in 32 bit color is about 307200 Byte or 3.07 Mega Byte.

An hour’s worth of one channel of uncompressed video at 25 frames per second would take up 21,600 megabytes (21.6 GB)

Uncompressed video of one hour will take hard disk space

Frame size 320*240 Pixel at 25 frames per second would take up
25*3600* 230400 Byte = 20736 Mega bytes
= 20.736 GB (24 bit color)
25*3600* 307200 Byte = 27648 Mega bytes
= 27.648 GB (32 bit color)
