High-definition (HD) technology is changing closed-circuit television (CCTV) systems everywhere. HD megapixel cameras offer many advantages over traditional security cameras but are still overcoming a few technology roadblocks. This page offers a very detailed explanation of these advantages and roadblocks, which we’d like to summarize here.
Advantages
An HD megapixel camera can do the work of multiple 4SIF cameras by providing clearer images or a wider field of vision. The HD images are good enough to identify faces and license plate numbers for forensic evidence. Also, HD megapixel cameras can zoom in faster than traditional cameras and still record the entire area for later viewing.
Roadblocks
To get the best images, HD megapixel cameras require higher resolution lenses that are more expensive than traditional lenses. HD megapixel cameras also need better sensors. Finally, HD megapixel cameras use a lot of bandwidth when transmitting their images.
The good news is that the industry is overcoming these roadblocks. As more HD megapixel cameras are installed, the price of the lenses are coming down. New sensors that are suitable for these cameras are in the works as are low-bandwidth camera designs. If you’d like to learn more about HD megapixel cameras and your CCTV options, contact us.
