![]() ![]() It’s handy for those managing fleets of vehicles, too, as incident videos are safely stashed online. Uploading to the cloud in real time is a nice hedge against damage and theft-assuming the thief isn’t smart enough to kill the dash cam immediately. Cloud storage is available with a few dash cams.Most dash cams will overwrite older recordings when they run out of space. Video is saved (protected from overwriting) automatically when an incident is detected. Video is recorded, then immediately overwritten at a specified interval unless saved. Continuous loop recording to minimize storage requirements.Don’t avoid 4K UHD-which is a feature in our best overall picks-but read the reviews first so you know whether the cost is justified. For most purposes,1080p is the more frugal everyday choice. In our tests, the gain in detail from 4K video (2160p) can vary, but the storage investment is consistently heavy: four times the storage of 1080p, or around 1GB for every three minutes of video. Do you need 4K UHD? It’s easy to fall victim to the specsmanship of a higher-res image.WDR (wide dynamic range) is much like above, except it usually refers to only color and not contrast.It also generally indicates richer color. HDR (high dynamic range) isn’t necessary, but it does make for more detailed video because of better contrast.Infrared lighting is important if you want to assure good captures of nocturnal events inside the cabin of your vehicle.Day and night video recording (night quality is a big variant).Note that the wider the field of view, the more fish-eye distortion there is, and more processing is involved to compensate. Some cameras offer 160- to 180-degree lenses. ![]() A decently wide field of view: You’ll see cameras with as little as 90-degrees field of view, but you’ll catch more of what’s around you if you go for 120 to 140 degrees.Interior cameras are generally situated on the dash cam, but rear cameras are separate and require additional cabling. Dual-channel support: This is what you’ll need if you want to run both front and rear, or interior (cabin-view) cameras.You can use Portable VirtualBox, but that requires installing VM software and an OS to run from.We’ll step you through what to think about when you’re shopping for a dash cam, from video capabilities, recording options, power connections, and more. We've detailed a method around this, but it's complicated and involves command line work. Unfortunately, the official "Windows To Go" feature from Microsoft is only for Windows Enterprise and requires a certified USB flash drive (which are expensive). By creating a portable copy of Windows and then booting to that USB drive, you will have your personal computer with your applications, preferences, and passwords all in a device less than a pound and small enough to fit in your pocket. ![]() You can solve all of this by putting Windows on a USB flash drive. Even if you don't commute long distances regularly if you consistently work with different computers as part of your career, you may find yourself often without the tools you need and sometimes the inability to change preferences that help your workflow. The more you take, the more you'll regret traveling at all, especially if you then need to walk far distances. You have limited carry-ons, and your suitcases can add to the cost of flying. Traveling is a pain, especially when flying. ![]()
