Outfitting your home with a security system often entails sticking a large camera on a bookshelf or the wall. Having a clearly visible camera on the outside can serve as an effective deterrent, but a large inside camera could potentially lead any intruder to break or steal the device. Plus, it can be a little unsettling to have a camera peering down at you, even if it’s the camera that you installed. That’s why a button-sized camera can be a good idea for home security. They can be hidden in a variety of places, allowing you to keep an eye on your home when you need to and forget it the rest of the time.
Mini cameras have other applications outside of the home. You can use them while you’re mountain climbing, for example, to capture a record of your adventure. Even the most compact adventure cameras, like the GoPro, are kind of large and can be cumbersome if you don’t have a convenient way to mount one. Mini cameras can be clipped to a shirt or backpack loop. If you ride a bike, you probably understand the risks of bike theft. A mini camera can be attached to your bike to monitor, so if someone tries to steal your ride, you’ve got the video feed. You can even attach one to a pet’s collar, just to see what they’re up to. There are a ton of applications, it just comes down to what features you want. These cameras are wireless, and they all record to MicroSD cards for easy on-the-go use.
