Advantages of your own DVR

DVRs have become a popular tool for drivers to record incidents on the road.

There, on the road, the jungle. Behind the wheel are wild animals using their cars as weapons and countless dills who don't know what day it is.

Road rage, insurance claims and back cover of the digital age, the latter supported by cutting-edge visual technology.

Now that the average person can capture an almost unlimited number of images on their phone every day, it's no surprise that cameras can record your every moment behind the wheel, as well as the antics of other drivers.

Miniaturization of smartphone cameras reduces the cost of so-called "crash cameras". These in-car devices are gaining popularity, especially in the UK and Europe among "professional" drivers or fleet companies.

An in-cabin device constantly records your driving, capturing small wing bends and full-blown crashes. After an accident or other incident, footage may be forensic evidence.

For the same reason, police officers now wear video cameras attached to their clothes.

"Fakes" of low price and unknown origin can promise a lot and not deliver

You can't argue with the video - no pigs, no denials, no bulls - and the file is easily transferred to a PC for viewing and storage. There is no shortage of such vision on social media.

You should be careful when buying a crash camera, because "fakes" at a low price and of unknown origin can promise a lot and not deliver.

This unbeatable online deal might not be the best way to go. The more discerning will go through a reputable retailer selling well-known brands.

The best crash cameras provide high quality images when installed in a 'set it and forget it' manner.

CarsGuide tested the Street Guardian's flagship model, the SGZC12SG V2, a model so packed with features that we barely touched on its capabilities.

Its G-force sensor saves footage when it detects sudden vehicle movement, such as hard braking.

It has a 2.7-inch viewing screen, Full HD resolution, wide-angle lens, and advanced low-light/night mode.

The image quality is one of the best we've seen on a dash cam, distinguishing license plates from a distance and sharp enough to be cropped.

Other handy features include a built-in GPS sensor for speed and location information. Its G-force sensor saves footage when it detects sudden vehicle movement, such as hard braking.

The driver can also activate this function, while the footage is stored on the internal 64 GB micro SD memory card. The included power supply (12V and 24V) has a large number of cables that can be hidden out of sight of the driver.

A great bonus is the rear-facing lens - the $429 V2 also doubles as a rear-facing camera.
