Useful Tips To Purchase The Right DVR Security System

1


A DVR security system, as the name suggests, makes use of one or more hard drives to store security videos. These devices are very different from regular DVRs, as they can record many video signals simultaneously, from multiple security cameras. This information is stored onto its hard drive, which can be played later for security review purposes. In this post, we offer you some useful tips on making the most of your DVR security system.

  • Number of channels

You will first have to decide how many cameras you need for surveillance. This means, you will have to consider the number of channels you want your device to possess. Usually, DVR security cameras come in configurations of 4,8,9 and 16 channels. Commercial devices can record over 32 channels. Since you cannot add on extra channels, it is best to purchase a security system with future use in mind. Connecting all your cameras to one device will also help with networking all the units.

  • Frames per second (FPS)

The second thing you need to consider is the number of frames per second that the DVR system is able to record. Anything between 24-30 FPS is the standard rate, so a device with this range will be able to deliver full motion video. There is one thing here though. If you were to connect two cameras to a four-channel 60 FPS DVR system, each camera will record at 30 FPS. But connecting four cameras to the same device will give you only a 15 FPS video recording, which would not be good enough for full motion recording.

  • Storage space

The storage space, that is, hard drive space for the device is also another important point to consider. Purchasing hard drive space will not be expensive, so it is better to spend on more space than you think you will need.

  • Type of encoding

The type of encoding used in order to compress the video is vital to save hard drive space. DVR security systems use three types of encoding, namely, MJPEG, MPEG4 and H.264. Of these, the last is the best, as it uses hardware to decode and encode the signal. This makes the file size smaller, yet, the picture quality better.

  • Triplex function

The triplex functionality allows the user to record, playback and view all videos simultaneously. Without this feature, the DVR will stop recording while you review the archive. In case you are looking to work remotely with your DVR security system, you will need a network-enabled system.

  • Turn your PC into a DVR security system

You can even turn your computer into a DVR system by using an interface card. Today, many security camera interface cards come with H.264 encoding, motion recording, Internet connectivity and more. This PC-based system also offers the great advantage of accommodating more cameras, DVD burning, USB connectivity, expansion of hard drive space and so on.

Conclusion

In conclusion, there are innumerable DVR security systems and vendors available today, both online and otherwise. Do some research beforehand and look through all the above points before finalizing a purchase.
