A very, very long time ago (two months - April 2009), I made a prediction that mobile telephones would eventually be able to stream live video to the Internet. [LINK] So far as I know, we're not quite there yet (out-bound live video streaming).
But a similar, not quite real-time, function is available now.
Modern "3G" mobile phones can capture a good quality still image or an SD-quality video, and then post it to a blog (or anywhere else on the Internet) with the press of a button or two. One simple approach is the 'mail-to-blog' feature.
Still images can appear on the Internet within seconds. Maybe a grand total of 30 seconds from pressing the shutter button, to the image being available worldwide on the Internet. Seriously. Literally about thirty seconds. From Click to on the 'net. 30 seconds. Wow.
Videos take a bit longer. It seems that many websites need to 'process' the video before it appears on the website and is actually available for viewing. This delay ranges from maybe two minutes to perhaps ten. But the video file will have left the phone within seconds (depending on the size of the file).
And these can all be linked to social networking sites for instant notification. I've a friend that monitors Twitter Trends so that he knows the worldwide news virtually as soon as it happens.
Sarcasm: Police agencies should save their money. No need to purchase expensive video devices and vastly overpriced storage 'service' recurring fees. For any disturbance in a public location, members of the public will provide more-than-adequate video coverage. Free.
