subject: Dvr Cameras: The Latest In Surveillance Technology [print this page] DVR cameras are, put simply, Digital Video Recorder Cameras: high-tech devices that can record video and audio in a digital format. DVR technology doesn't have to be used alongside a camera - as long as it has some sort of video source, it can record from that source. Combined with a camera, it records whatever that camera is filming. Combined with a television, it records what's currently showing.
Recording to digital format has a number of specific advantages, including the fact that the footage can be recorded directly to a hard drive. This can then be transferred to external multimedia, such as DVD or CD, if needed. Because of this convenience, DVR is becoming more and more popular in the latest television sets to help people record their favorite shows from cable or satellite.
The New Trend in Video Surveillance
As well as including DVR recorders with cable subscriptions, DVR cameras are now being used as part of home video surveillance systems. Because they don't need any film to record, they're far easier to store than traditional tapes which would have to be held physically for long periods of time.
On top of this, there are also more options for playback with DVR cameras, which traditional film can't offer. This means that you can fast forward footage, rewind it, or reverse it all at the same time as the camera continues to record. This kind of option is known as triplex functionality due to the number of functions you can perform at the same time.
Many businesses and homeowners are now choosing to incorporate DVR recorders into Closed Circuit Television systems to allow them to keep a closer eye on what's going on around a number of locations in the building.
Spy Cameras
Many parents are even using this technology to keep an eye on their children or the nannies when they aren't there. This is because DVR can be incorporated into such small devices that people will never know they're being filmed! One of the options is to use a key fob camera which looks just like a car opener but has the ability to record what's going on.
DVR cameras really are revolutionizing the world of home surveillance. Whether you want to keep an eye on your home while you're away, or help deter criminals from your business, a DVR camera is the most convenient way to go about it.
