There is at least a waterproofing kit included so you're not leaving 12V DC exposed to the elements. And the app, while neat enough, could do with a little touch-up to make it clearer and rephrase a couple of the more poorly-translated options. The resolution indicates the size of image that is captured by the camera, the larger the image the clearer the image will appear. Higher resolution cameras are ideal when viewing footage on a large TV screen. Lower resolution cameras are perfect for viewing high definition video on your smartphone or tablet. EZVIZ The EZVIZ C3TN Wi-Fi Smart Home Camera, With Colour Night Vision is easy to set up and use, with automatic recordings and real-time viewing via your smartphone, tablet or PC. With high definition video recording, the C3TN Wi-Fi Camera has expandable storage via an SD card slot (Max 256GB), and also includes cloud storage facility. The camera includes two bright spotlights, when motion is detected, to deter intruders. With colour night vision, the C3TN Outdoor Wi-Fi Camera lets you monitor your property at day and night. With easy set-up and functionality, you can be set up and recording within minutes. It's good, then. But the Ezviz C3N is not a camera for everybody. Renters, for example, maybe won't be able to install it at all, given that doing so involves boring a hole through your wall for at least the power cable and perhaps (if the 2.4GHz-only Wi-Fi won't stretch) an Ethernet cable too, something you'll need to work out on your own given the rudimentary supplied instructions.
