How many hours worth of surveillance will a Mpeg4 Digital Video Recorder with a 250GB hard drive hold? - digital surveillance recorder
I will be a system of closed circuit television buy for the job. Pending an answer to my inquireies directly to various representatives of the selling company. If I want to see what can those of you with the experience of CCTV to tell me. I have systems with hard drives smaller than those times I am in the possession of 3 weeks worth of 24 / 7 video on demand. I do not know what kind of resolution, the a. Generally, when I will be a 250 GB hard drive from the right resolution I wonder (for the identification of areas of less than 10 feet) and at the same time, a few weeks, the value the stock before I have to write to disk or rewind the video on CD-ROM. Let Holsbrook .. what you already have for me? :)

Digital Surveillance Recorder How Many Hours Worth Of Surveillance Will A Mpeg4 Digital Video Recorder With A 250GB Hard Drive Hold?

All other posters are correct before me. My experience:
Security DVR in my system is still configured so that every 4 seconds. There are four cameras to show at various locations. The DVR has an output unit 200 (and up to 250 GB, I think not) understand at the time. The DVR has a feature that the motion in the visual field of the video camera can see - and you can specify the range of motion detection. When motion is detected in the above area can, the DVR will start recording the camera video stream in real time. The four cameras can record in real time simultaneously.
While the areas not covered so busy that lasts 200 Concert generally take a little more than 30 days to complete. Then it's first-in/first writing. The camera picture resolution will be as important as the compression used by the storage of firmware images on the DVR ... but at least 10 meters, you should have difficulty identifying faces ... This is a good camera angle (closer to the horizontal is best).

Other considerations:
1) You may need night vision.
2) CAT5 twisted pair cable works great - coaxial cable for runs under 100 feet, or near fluorescent lighting or power adapter is not required.
3) Make a good backup battery size. To do in case of power failure, not from your system without power. You can use a large UPS that normally power a computer for backup. The supply of electricity to the camera and DVR - and at least a flat screen.
4) Of course - like the BIG screws and heavy belt - the DVR to do something, or in an enclosed area (strong), well ventilated area (shelf, rack, whatever). Better to hide. It would be a burden to go through it, just because poor people take only the DVR (and thus) their evidence.
5) Consider a flat-screen TVs showing visible, which have a video surveillance system - aDS of "Alert" is sharp, too. * Could be * This is a different system - so that the poor only if can not see the video camera and do bad things are ... The "others" might be in these areas.
It is a bit difficult to answer because there are many factors, such as frame rate, the number of bedrooms, compression codec, resolution, motion capture vs. continuous recording, etc.
I worked only with professional systems and had several terabytes of storage for 10-14 days retroactively, but with 16 cameras.

Another question is: What kind of evidence you need - need to have up in court or simply to convince someone that you know what they are doing? Many closed-circuit television in the United Kingdom are not good enough to be used in court. If you are in the UK, make sure you understand the Data Protection Act - applies to video surveillance systems.
This site is a good guide to the information you want. From what I can see, would be able to absorb about 3 or 4 frames per second at 640x480, with all speed for 4 weeks.
