With modern improvements in mobile technology almost anything is possible. Most cell phones take photos these days, but not many shoot mobile video. Those that do, don't do it well. For the true spy in training needing streaming evidence the only true solution is to get a keychain video camera.

The key-chain video camera can be used covertly. It is very common for people to take their keys out of their pockets while sitting. Keys get uncomfortable. They can easily get dislodged and inadvertently stab you in the leg while sitting. It is distinctly for this reason that your "mark" will never suspect a thing as you nonchalantly twirl your keys onto the table. Little does he know your keys come complete with a hidden keychain camera. Private detectives, hobbyists, artists, criminals, parents, and spouses have all successfully used this technology to learn waht is really going on in their lives and relationships. Get the facts. Get the video.
Picture Quality has improved over time as technological advances have made it increasingly easy to produce the necessary performance devices smaller and smaller. Imagine the people of two hundred years ago if we were to drop off an iphone into their lap.
Mobile video technology has allowed global citizens of earth to film, upload, and display their day to day feats. Never before has every single person across the world had the ability or access to this sort of a stage for their vision. Beyond spying on your neighbors and peers with a camera, you can upload videos of you skateboarding and show them to your friends. Make a video of your band or a friends band. Anything you are passionate about can be put on film and shared easily worldwide though youtube, or perhaps your own website.
If you are out on the down and you see a random guy bust into the robot dance it would probably make you laugh. Twenty years ago you would be without the mobile technology to be able to share that with a friend. How frustrating it was to not be able to share that story with your friend effectively. Without seeing the dance the story lacked the true effect. Looking through video cameras like this allows everyone to review historical events, silly moments in time, and catalog pure life.
