The capacitor draws its power directly from the car, but only while the car is running.
As a less pricey alternative that should work when it’s too hot (and also, in some cases when it’s too cold) for a battery-operated dash cam to do its best, we find it meets the bar.
It comes with a 32 GB micro SD card—a capacity that’s big enough for many people’s needs—but it will accept cards up to 64 GB.
I bought one so far, but will definitely be buying more for friends and family. After just minutes of plugging in the camera, downloading the free Tend App for my i Phone, and connecting to my Wi Fi, I was up and running. Being able to check in on our cat while at work or review recorded video clips of our cat from the day is so much fun. But, the best part of this camera that sets it apart from others is the Pet Highlight Reel.
It takes the motion-triggered recordings from the day and turns them into an excellent highlight reel, embedded with fun music options that you can choose from.
Instead, it focuses on great image quality and reliable, automatic operation each time you get in your car.
Other cameras tick these boxes as well, but none hit them all quite as perfectly as the Z3 while also selling at a great price. The camera features exceptional 2560×1080 resolution at 30 frames per second.
Its images are just a hair too dark compared with the Z3, but they still blow most other dash cams out of the water, leading us to recommend this as an alternative choice if it’s competitively priced with the Z3 or the Z3 isn’t available.
If you live where temperatures regularly cook your car, we recommend the Spy Tec G1W-CB.
It has a number of drawbacks relative to our top pick—a lower-resolution, 1080p camera for one—but it uses a capacitor instead of a battery.
Batteries perform poorly in extreme heat, delaying or preventing a camera’s boot-up or normal function.
But there are more entertaining and socially useful purposes, as well.
You’ve almost certainly seen the You Tube footage of meteor strikes (again in Russia) and from police cars.
Additionally, I’m a photographer who frequently experiments with new camera technology, both still and video.
