Your camera might have Wi-Fi control. It might not. It doesn't really matter, because there's no chance it can match the features of the Pulse Camera Remote. This Bluetooth-based remote sits atop your camera's hot shoe and connects to it via USB, giving you an unprecedented level of control. It can do all the normal things, like set the aperture, shutter speed, and ISO, take photos, and record video, and give you a preview of the image. But it also enables super-precise control over long exposures without the need to sit next to the camera, and has advanced timelapse features that let you ramp the ISO and shutter speed over time to match the changing natural light. Compatible with nearly every modern Canon or Nikon DSLR, as well as the Panasonic GH4.
As rugged as they come and packed with tech, the Olympus Tough TG-Tracker Camera is the action cam for the data hungry. It uses a bevy of sensors — including GPS, a barometric pressure sensor, an accelerometer, an electronic compass, and a temperature sensor — to record data about your location and the conditions, all while the 204º f/2.0 lens and UHD sensor capture 4K footage of your exploits at 30 fps. And since most adventures get a little messy, it's also waterproof down to 100 feet, dustproof, shockproof, freezeproof, and crushproof, so it can handle whatever you throw its way.
