Living with two 'budget' dashcams, the Mobius, and A118C, in an OTR Tractor Trailer

The image quality is comparable.   The A118C has a wider angle lens than the standard Mobius, lens.
In the following video, a segment from Mobius 'A' model is first, followed by video of the same event from an A118C.  Both are around $80 through online retailers.

Both cameras are pretty easy to use, the Mobius does require a laptop or android phone to configure.
I've not had luck with the android program, but I have not messed with it much.   You will need the appropriate cable or adapter to use an Android phone to program a Mobius.   I use my laptop, much easier, never even pull the card out, or remove the cam from the windshield.   I'm powering both cams from a 2 way Cig Lighter outlet, with 2 USB ports, attached to the normal 'CB' wiring in the overhead console.  (I don't run a CB, anyway)     On my truck it's easy to use USB cables to power the cams, and tuck the wires  away in the cracks of the wonderful plastic interior material of my 'South of the Border' made Cornbinder.   Easy, looks neat.    Not much in the way of dangling wires.  Moves or removes in seconds.


A118 HD 1080p Car Dash Camera - $79.95

I have not messed with the GPS on the A118C.   Other than keeping the time updated on the Cam, not sure how useful it will be for me?    I want video.   If I am in a major accident, the black box features on this annoying truck will provide more info than any aftermarket electronic device will.
(Oh, you didn't know these new trucks spy on you?)

Both cams are good for the price, but make sure you understand what you are dealing with.  No dashcam seems to do well at night.       The 'motion detection' features of some mostly seem useless, and cause more problems than they are worth.
The screen on the A118C is ok.   You  aren't going to see much when it's mounted, and in the normal mounting position in a tractor trailer.  It's mostly an indication you have it pointed the right way, and it's working.    
The mobius has no screen, and only a few small LEDS that will indicate functions.    I have configured mine to operate automatically.  On, when the power is on, off when the power (Key) is off.   I have yet to touch the three buttons on the Mobius, although you'd need to use them if you  use a Mobius as an action cam, and they are very popular in the RC World.



Please avoid the dashcams you may see for sale at the chain truckstops. They're usually overpriced, and of modest quality. Do you think you are really buying a 'name brand' cam when you buy a Garmin or Cobra at the truckstops?



Those dashcams are made in the same chinese factories, under contract, as many 'no name' cameras, and often the 'no name' has better video, online support and information, at half the price.



 Here is a sample of night video from both dashcams.
