Not all security DVRs are created equal. That’s why it is important to know the key features of a DVR before you make a decision on which one to purchase. Here are some key factors.
A DVR hard drive is what your video and images are stored on. The size of the hard drive determines how much footage you will be able to record. According to Home Security Store technician Matt Apperson, it is recommended that a security DVR have at least a 250GB hard drive. This will get you about 84 hours (3 ½ days) of high quality video if recording continuously with four cameras in quad mode.
Number of Channels –
Before you buy a DVR you should decide how many cameras you would like to use. That’s because the number of channels your DVR has will determine the number of cameras you will be able to use. Apperson recommends, depending on the size or your home or business, that you have at the very least 4 channels. A typical security DVR has 4, 8, or 16 recording channels.
Pentaplex Operation –
You will want your DVR to have pentaplex operation. A pentaplex DVR allows you to view, record, playback, back-up, and remotely control your DVR all at the same time.
H.264 compression is used for efficient file transfer and storage. Apperson says your security DVR should have this video format compression to allow you to save more video on less hard drive. Basically, it’s like defragging your computer.
Web Capable and/or Web Ready–
Many DVRs are web capable and/or web ready. Web capable means your DVR is internet compatible and can be set-up as such. Web ready means the DVR has its own embedded server and it basically a plug-and-play device right out of the box. DVRs can also be Blackberry, iPhone, and/or 3Gphone compatible.
In addition, your security DVR should allow you to record on a continuous mode, a motion detection mode, when a sensor is triggered, and by a timed schedule. The unit should also allow for control over recording quality and frame rate. Plus, allow you to search by event, time, date, and camera.
Remember, a security DVR used in a home or business can cost anywhere from $350 to $10000 depending on your needs and expectations. Therefore, you should arm yourself with knowledge before you pull out that checkbook.
