245 Million Security cameras.
According to their recent report:
IHS has been tracking annual shipment volumes of video surveillance cameras for over ten years. This report builds on this decade of research to provide, for the first time, a dedicated analysis of the installed base of network, analog and HD CCTV security cameras.
Here's the methodology paper.
Breakdown by type:
- HD CCTV: ~2%
- IP Cameras: ~20%
- Analog/Other: ~78
Asia was listed as having 65% of all installed cameras. For vendors, Hikvision ranked first, and Samsung Techwin ranked second, which seems a bit unlikely.
For network cameras, Axis is ranked #1 and Hikvision #2. Look for Axis to update their website shortly.
I believe that the HD CCTV number includes CVI and SDI but I could be wrong. Anybody who has a subscription to IHS is welcome to clarify.
245 Million Cameras at D1 resolution works out to be about 10K pixels per person. So the whole world could take a group snapshot at the same time. Find your camera...
