We are getting prices for a Security system & CCTV system one quote says we need 8 Channel DVR with 250 GB &?
USB Back Up is 250GB big enough for 8 channels??? and what is the best system to use ?
There are too many unanswered issues here that you have not mentioned for anyone to give you a reasonable answer.
For instance, you have not told us the resolution that each of the cameras connected to these 8 channels will have. You have also not told us if any video compression will be used or not on these video streams. Other questions to ask.. do these cameras record all the time or do they only record when triggered? How much video do you want to be able to record?
My out of the box Directv high def DVR had something like 320 GB and would store something like 40 or 50 hours of high def compressed video. Obviously if these 8 channels are each high def, you are down to just a few hours worth of all the camera recording and, as an example, there doesn't appear to be enough capacity there to record an 8 hour shift of all cameras.
I don't know how this system is going to be used and I don't know how much video you feel you might need to record. These are requirements such as the ability to record x hours of video at y resolution are requirements I suspect you should be defining to your vendors. At the very least, you should be asking these specific questions to your vendors.

When one monitors their home or office with closed circuit television (CCTV) surveillance, it’s equivalent to having an entire television network dedicated to the safety of one’s entire house. CCTV broadcasts security surveillance on a private in-home network. Unlike broadcast television, CCTV components are hooked directly to each other via cables or direct wireless means. Already popular in large public places where security is heightened, such as at airports or casinos, CCTV surveillance systems are rapidly becoming more used in private homes. In addition, CCTV is an inexpensive and simple way to increase one’s peace of mind.
A number of independent studies in the United States have suggested that CCTV surveillance stops numerous crimes before they happen. Other studies also show strong evidence that CCTV can be a great benefit in detection and prosecution. A large amount of cases have been solved simply by the use of CCTV cameras in public places. Not only can it stop crime, CCTV can solve crime as well.
The same CCTV video surveillance technology used in public sites is readily available for anybody’s home. Now CCTV systems can monitor every room in your home with clear, high visibility images. CCTV surveillance is available for up to 16 rooms in your house. By monitoring your family's security on a CCTV network, one is able to record suspicious activity as it occurs. One can also monitor their yard, front door, garage, and even their mailbox. CCTV also offers multiple features that allow one to monitor separate areas of their house simultaneously and in real-time. Such features as: multiple channel video input, multiple channel audio input, real time display, pan/tilt/zoom, and USB backup.
CCTV security surveillance is a powerful addition to anyone’s home security system. Everyone has the right to feel comfortable in their own house. Your home is your sanctuary; therefore you have the right to protect it.
