WHAT’S IN STORE FOR THE VIDEO SURVEILLANCE MARKET?

FROM ANALOG TO IP, BETTER IMAGE QUALITY & MORE

Over the last several years, a hot topic in video surveillance has been the migration from analog to IP, and what’s required in order to make a smooth and successful change-over. While that’s certainly an important discussion, there are several other emerging trends and technologies that are not only reshaping the infrastructure behind video surveillance, but also transforming how organizations of all shapes and sizes are fundamentally using this technology.

By the end of 2015, more than 70 percent of all network camera shipments will have megapixel resolution∗. This shift is happening due to:

• Improved compression codecs (H.264)
• Networks (networking hardware, server and storage) supporting IP surveillance are higher performing and purpose built
• Better image quality, higher resolutions give more useable image detail
• Improved performance of high resolution cameras in difficult lighting conditions (e.g., lowlight and WDR)
• Reduced storage costs
• Better coverage, potentially reducing camera counts

High-definition resolution provides up to five times higher resolution than standard analog. The two most widely used high-definition standards come from the Society of Motion Picture and Television Engineers (SMPTE): 296M (720p) and 274M (1080).

In essence, 296M defines a resolution of 1280×720 pixels with high color fidelity in a 16:9 format using progressive scanning at 25/30 Hz and 50/60 Hz. 274M defines a resolution of 1920×1080 pixels with high color fidelity in a 16:9 format using either interlaced or progressive scanning at 25/30 Hz and 50/60 Hz. A camera that adheres to one of these standards indicates HDTV quality and provides the benefits in resolution, color fidelity and frame rates.
