Lower lifetime costs (no more piles of VCR tapes). More recording time (up to 2-4-8-24 weeks or more at a time with an 80GB - 300GB  hard drive model). What’s not to love about DVRs? Digital Video Recorders save digital images to a hard drive through one or more CCTV cameras (4-8-16-32 options). Thanks to recent technology advances, DVRs are becoming inexpensive enough for even the home user. It handily replaces the time-lapse VCR. No more tapes to worry about or accidentally erase. If you’re familiar with TIVO, basically, it’s the difference between using your old VCR (to tape shows) and a TIVO (to digitally record shows). Over the long term, removing the cost of buying videotapes significantly reduces the cost of a video security system. A DVR is the ideal add-on to any CCTV Camera when you need extended periods of monitoring. Perfect for businesses that have to rely on their security camera system to monitor continuously, or just great for when you go on vacation. There are many cases, where you just need extended recording capabilities if you work late hours. Maybe you just plain don’t want to keep running to the VCR every day, and to constantly replace tapes, or maybe you’ve already accidentally recorded over your favorite TV show one too many times. Avoid all these hassles with a DVR. (Motion activated) We’ve expertly selected some of the best for you to choose from. Need to take it with you? No problem. We’ve even got Portable Surveillance DVRs, these pocket-size versions come in smaller than a Walkman — but with big 20-40-80Gb hard drives. Some even do double duty as entertainment systems, so you can listen to MP3s or watch pre-recorded TV shows. Maybe not the primary reason you’re buying a DVR, but why not have a little fun in between stakeouts? And if you were planning on buying an IPOD or other MP3 Player anyway, a DVR entertainment system (that can also record surveillance footage) will practically pay for itself.
