Best Action Cameras Under $400

When looking for the best action camera, who would not want the complete package? Great specs, great features, and a friendly price! One of the first things that come to people’s minds when it comes to this is GoPro. Well, it’s true, and this list would be incomplete without a GoPro camera. However, there are also some notable amazing action cameras that you can find in the market. With that, here are the top 3 best action cameras under $400!

1. GoPro Hero 9 Black

Although not the latest GoPro Hero model, the Hero 9 Black was released in 2020 by GoPro. Despite having the same shape and size, it is still indeed a big upgrade over its predecessor GoPro Hero 8 in terms of specifications. It has better image stabilization than the Hero 8, and it has a front-facing colored LCD screen to make it easier for you to create selfie-like videos!


Here are some of the best specifications of GoPro Hero 9:

  • 5K Video Resolution with a maximum 30 FPS
  • 23.6 Megapixels Camera Sensor
  • 20MP Photo Quality + 14.7MP Video Stills
  • Improved image stabilization
  • Larger rear display than Hero 8
  • Front LCD Display
  • 30% Larger Battery Capacity than Hero 8
  • Great Low Temperature Performance

Of course, one of the things that grabs the attention of people is the staggering 5K video resolution, but it gets even better because if you need more than 30 FPS, you can lower the resolution a bit to 4K at 60 FPS, or even 1080P with a very smooth 240 FPS! It is perfect for people who are also planning to create slow-motion shots without making the video resolution suffer too much.

For the battery, this is the new feature that GoPro highlighted the most. The GoPro Hero 9 has 30% more battery life than the GoPro Hero 8. However, the only disadvantage to this great feature is that the battery size has also increased. This means that you cannot use your batteries from your old GoPro Hero models to the Hero 9 model.

New Features

  • Scheduled Capture – This is pretty much self-explanatory. As the name suggest, this feature lets the user to schedule a recording for up to A WHOLE DAY (24 hours) in advance.
