Digital Video Recorders (DVRS) in Surveillance

Security cameras have come a long way since the early days. Advanced technology, like DVRs,Digital Video Recorders, or NVRs, Network Video Recorders, have replaced most videotape-based systems.

Instead of using time-lapse VCRs and multiplexers, a DVR records video on a hard drive. This eliminates the need for tapes and makes the system easy and safe to access online or through a local network.

How to choose the best system for you

Your ultimate choice will depend on several factors: How many cameras do you want to connect to the system? Is your security situation commercial or residential?

Taking a look at the video recording rate versus your hard drive’s storage should play a major role in your decision. This will allow you to make sure you have enough space to record video at the rate and resolution you have planned.

In most cases, a low recording rate is usually sufficient, but for increased security needs, such as recording each camera at its highest resolution and the maximum frames per second, opt for a DVR that has a high recording rate and the necessary hard drive storage.

Your choice in DVR matters

Two types of Security DVRs exist: Standalone and PC-based.


PC-Based DVR

PC-based DVRs come with 4, 8, 12, 16 or 32 camera inputs and convert analog signals to digital signals so they can be easily compressed and shared. You can then store the images on a computer, and easily search and retrieve your security history.

One major benefit of PC-based DVRs is that you can expand the number of supported cameras by adding additional DVR cards to your computer. These cards are available from all the main manufacturers.


Standalone 4 Ch DVR

The second type of system is called a Standalone DVR. These are great for home security as they allow you to monitor your footage while you watch TV, and control the image with a remote.

Do your kids play outside in the pool or in the street a lot? Do you have to park your new car on the curb? Watch it all in real-time from the comfort of your couch with a Standalone DVR. The high-resolution image and sharp video playback will keep you happy and secure at home.
