will soon be video survallance systems... For too long home security cameras, business and even many traffic cams have suffered with images that lack detail but with the rise in 4k cameras (and beyond) the time for a massive upgrade cycle is nearly at hand. Ambarella's technology will be in many of these upgraded system... It doesn't take a crystal ball to see the changes coming; in fact, the nightly news often contains grainy images of perps caught in the act.
A better question is, "who is using Ambarella's 4k products for security cameras". If you want the best you need to buy the best but don't necessarily need to pay the most. BTW, pretty soon you'll be able to use drones to monitor your property :)
