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.
There are many advantages to recording in digital format. Recording can be done directly to a hard drive, which can be transferred to other multimedia when you need it (such as CDs or DVD). Because it's such a convenient option, DVR is becoming more popular as a part of the latest television sets to allow people to record their favorite shows.
A New Trend for Video Surveillance
You won't only find DVR recorders as part of a cable subscription: this technology is now popularly being included in home surveillance systems. The benefit is that they don't need to be stored physically over many years, like traditional video tapes do. They don't require any film to record what's going on.
Some other benefits of using DVR cameras for home surveillance include the fact that there are many more playback options than with traditional video film recording. The footage can be fast forwarded, reversed and looked at in detail - all at the same time as new footage is being recorded! This is known as triplex functionality, allowing you to perform a number of functions at once.
Homeowners and companies are now making use of DVR technology through Closed Circuit Television, helping them to keep an eye on what's going on in many different locations throughout the property.
DVR 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.
Thanks to DVR cameras, the world of home surveillance is changing for the better. If you want a good way to deter criminals, or simply to keep an eye on your home, then a DVR camera could be the best choice for you.
