HDCVI – The Low-Cost HD Security Camera

Surveillance cameras usually do not come cheap—especially the highly-sophisticated ones that can provide higher-quality and clearer videos. However, there are low cost alternatives to pricey security cameras and you can consider them for your home or business. The HDCVI is a good option in low cost HD security cameras. The name stands for high definition composite video interface, and it uses technology that transmits video signals in a different method over coaxial cables.

Before HDCVI, analog CCTV was the norm. The problem was its resolution, which was limited only to 960h—meaning, there is a 30 percent increase in the horizontal resolution, resulting in a 960 x 480-pixel maximum resolution. To improve transmission, you would usually have to upgrade to digital video via HDSDI or network IP formats. With HDCVI, you can have a cost-effective network IP solution that relies on a video transmitter and a receiver that can transmit videos in a resolution of up to 1080p or 1920 x 1080 pixels. The videos are uncompressed and can be sent over standard coaxial cables used in conventional CCTV camera systems.

The uncompressed video of HDCVI can be transmitted over longer distances without bandwidth and latency issues, which were common with conventional network IP and HDSDI cameras. HDCVI can transmit control (PTZ or OSD), audio, and video over a coaxial cable, too, so you do not have to worry about having separate cables for every kind of transmission. HDCVI systems cost almost the same as older CCTV analog technology, but they are far more affordable than IP network or HDSDI cameras. Hence, if you have to choose between analog CCTV and HDCVI, consider going for the latter to get higher resolution for your money. Some providers of security surveillance cameras solutions give free software to enable remote moving, and surveillance apps for your tablets and smartphones to go with the HDCVI system.

Higher-end door access control systems offer multiple authentication methods, which may include voice recognition and fingerprinting.
