A big part of what’ll dictate which analytics platform you should use will depend on your budget. If your company is super data rich and every department is highly dependent on accurate reporting, you might already invest in a robust paid platform that can meet your video needs. If not, there are tons of free tools you can use that are just as good as some of the bigger, paid-for options.
Professional cameras, like DSLRs, give you fine control over the manual settings of shooting video and allow you to achieve the shallow depth of field (background out of focus) that people rave about. While they're primarily used for photography, DSLRs are incredibly small, work great in low light situations, and pair with a wide range of lenses — making them perfect for video. However, DSLRs do require some training (and additional purchases) of lenses.
