Shortlists
Each one is a filter over the same catalog, so nothing here can name a camera we have not recorded specifications for. Every list says which specification it is ordered by, and a list that would qualify fewer than 3 cameras is not published at all rather than shipped short.
Dual-channel dash cams under $250
Two hundred and fifty dollars is where a front-and-rear kit stops being a compromise. Below it you are usually pairing a decent front camera with a 1080p afterthought; at it, the rear channel starts being evidence rather than context. These are the two-channel cameras that fit, ordered by front pixel density.

Dash cams for hot climates
A parked car in summer sun gets hotter than a lithium pouch cell is designed for, and a swollen battery is the classic way a dash cam dies. Every camera here uses a supercapacitor instead, which cannot swell, and every one publishes a temperature range — because a supercapacitor camera whose maker will not state a ceiling is asking you to take it on trust.

Dash cams that record the approach, not just the impact
Most parking modes start recording when the G-sensor fires, which means the car that hit you is already leaving by the time the file opens. A buffered mode keeps a rolling few seconds in memory so the approach is saved too, and a radar mode wakes the camera before contact. These are the cameras that do one or the other.

Dash cams with an infrared cabin camera
An ordinary sensor sees nothing inside a car at night. Infrared LEDs light the cabin invisibly and turn it into usable monochrome, which is why every camera sold to rideshare drivers has them and why a cabin camera without them is close to useless after dark. These are the models that carry one.

The highest pixel density in the catalog
A 4K camera behind a 170-degree lens resolves less detail per degree than a 1440p camera behind a 125-degree one. These are the cameras at the top of that calculation — the ones where resolution and field of view are working together rather than against each other. The figure is computed from published specifications; see the specs guide for what it does and does not tell you.

The rear cameras that can actually read a plate
Most rear cameras are a 1080p sensor behind a 160-degree lens, which puts about thirteen pixels on each degree of view — enough to show that something hit you, not enough to say what. These are the exceptions: rear channels with either more pixels, a narrower lens, or both.

Screenless dash cams
A screen is useful for aiming a camera once and a liability every night afterwards. Screenless cameras are shorter, tuck closer to the glass, do not glow in your peripheral vision, and give a passerby nothing to notice. Setup and playback happen on a phone instead.

The cheapest cameras that are not battery-powered
At the bottom of the market a lithium cell is normal, and it is the wrong part for a device that spends August on a windshield. These are the cameras under a hundred and eighty dollars that use a supercapacitor instead — the single specification most worth protecting when the budget is tight.
