This is the fourth generation of one of the most popular security cameras on the market. Blink's reputation is, we should acknowledge, partly garnered by being an Amazon-owned company, so it gets brilliant positioning and discounts at certain times of the year.
To say that Amazon's ownership is the only reason Blink is well-known is to do it a disservice. The cameras, especially the outdoor versions, are well known because they solve an issue: battery depletion. Blink came up with the idea of using long-life (Lithium AA) batteries in an outdoor camera, and the compromise made is that it cannot record indefinitely, but distinct video clips, limited to 60 seconds or less.
