How do these dash cams function? Do they turn on/off automatically with the ignition switch, or does one have to remember to start them? What happens when the memory gets full? Are they affordable or expensive? Easy to install or difficult?
You can set most decent cams to come on with ignition, come on with g-forces (parked car getting bumped) or always on. I'm looking to get a set for my car that can also be moved to my truck/trailer. I have zero issues with using a wired connection.
When the card gets full, it starts overwriting the older footage. Virtually =all= cams have a "bookmark" feature where you can bookmark a spot and it will automatically save, usually, the 5 mins before the button push and 5 minutes after. It is locked from being overwritten. I =think= if you push the button more times, it locks out more time on the card.
Like anything, dash cams can be had for pretty cheap or pretty expensive. All depends on the quality and features you want/need. Installation runs the same way. You can choose a "portable" install, where you've got wires running all over, or a "permanent" install, where wires are hidden. Also, a lot of people that choose to have the always on feature will install a dedicated battery for their cams. Another feature, especially for hotter climates, is to get a cam that has a "super capacitor" instead of a battery. They are =much= more reliable than batteries in hot conditions.
