Before Buying CCTV DVR System – 4 Checklists


Today’s CCTV DVR technology offers more sophisticated surveilling capability. The cameras have adequate capabilities of recording, monitoring, and reviewing activities outside and inside your property.

However, the task of selecting the right DVR can be quite intimidating. With so many CCTV DVR products available, understanding exactly what you need might be confusing. Some DVRs may seem almost similar by physical appearance, but they are absolutely different.

Your decision should specifically focus on the level of investment you need to make. For that matter, an entry level unit or a high end unit can help you achieve your targets. Regardless of whether you are new to CCTV or you want to improve an existing system, considering the following four (4) major specifications to help you get the right CCTV DVR.

1. Resolution

Resolution is the image size being displayed by a CCTV DVR. Currently, the highest resolution display in an impartial DVR is D1 (720 x 480). However, CIF (360 x 240) is the most common resolution in DVR industry.

There are other resolutions such 4CIF image, which has 4 times resolution of a CIF image. Therefore, a good DVR should have a high resolution to give more detailed image. A high end unit is the best since it can record both 4CIF and D1 resolution in 30 frames per second on every channel.

2. Storage Capacity

Storage capacity of a DVR is an essential feature to put into consideration. Lower end units can only allow 1 to 2 hard drives, while high end units allow 6 to 8 hard drives.

Most advanced units allow redundant storage (RAID) configuration, as well as, FTP uploads. FTP uploads allow the DVR to back up video to an off FTP server. This is a vital tool since property owner can retrieve a video in a case where even the DVR was stolen.

3. Frame rate

DVR Frame Rate is the number of frames recorded per second at a given resolution. Real time is well thought-out to be 30 frames in every second. Recording a real time video on 16 channels you need a DVR that can record 480 frames in a single second. Therefore, a high end unit is most preferably since it can record 30 frames per second on each channel.

4. Compression

The purpose of compression is to conserve storage space after a video has been transmitted to the DVR. In addition, compressed video enhances straightforward viewing through the internet.cctv dvr price

Compression varies from one method to the other, with the highest compression being H.264. MJPEG method involves almost no compression, but MPEG4 has a high compression almost next to H.264. Therefore, H.264 is highly efficient for both internet streaming and storage conservation.

The above discussed specifications are useful to any business owner or home owner when buying CCTV DVR. Since you have some light about major specifications to consider before buying a DVR, let’s look at three models best suitable for both homes and business premises;
