None are ultra-high definition (UHD), which requires 8 MP. The majority of inspection cameras use 1080p resolution, also known as 2 MP (though to be picky, it’s actually 2.1 MP). The resolution is actually 1280 x 720p, which is a total of 921,600 pixels, just shy of 1 megapixel (MP). Inspection cameras start at 720 pixels (p), which represents the number of pixels on the shortest side of the image. However, the maximum resolution is usually what we look for. Lower resolution means smaller file sizes, so you can store more images, and many people don’t need a highly detailed image. Some inspection cameras have switchable resolution. We’ll start by clarifying how these things apply to inspection cameras.
Things like megapixels (MP), high definition (HD), and whatever ingress protection (IP) rating devices have can all get a bit confusing. You can not only see into tight spaces with an inspection camera, most can be fitted with a hook or magnet so you can fetch things, too! Key considerations We’ve also compiled the following comprehensive guide to provide the in-depth information you need to understand the features of each model before you buy. The BestReviews team has been assessing a huge range of different instruments, and we’ve put together a shortlist of recommendations that offers a variety of price and performance solutions. Picking the right one can be challenging even for experts! Given the wide range of tasks, it’s no surprise that there are plenty of different models from which to choose: different diameters, lengths, camera resolutions, USB and WiFi models that work with your smartphone, tablet, or laptop, and cameras with dedicated monitors. Inspection cameras are popular with DIY enthusiasts, plumbers, electricians, mechanics, building inspectors, engineers, and a whole host of other trades. There are the obvious uses, such as finding blockages in drains (or items dropped down them), then there are the not so obvious, such as locating pest infestations or checking rifle bores. A good inspection camera is a remarkably versatile device.
