I was a bit confused by this also. The sensitivity is for the monitoring impact. When the dash cam is plugged in via microUSB cable, the sensitivity sensor “locks” the clip from being erased/re-written on the microSD card…when there is a sudden braking or impact. Then, there is also “parking monitor” sensitivity. With that, the sensitivity sensor triggers the cam to start recording the 30 second clip and automatically locks/saves the clip. Hope that helps. Just remember, if the dash cam is plugged in, the dash cam automatically takes either a 1, 3, 5, or 10 minute clip (depending on the setting you select, with the new firmware update). Otherwise, when it isn’t plugged in or powered by external power source (but using only the dash cam’s internal battery), the recording is only triggered when the sensor senses a bump or hit to your car (ex. someone bumping your car)… and again, only takes and automatically locks/saves a 30 second clip.

Thanks for that. Don’t know why it isn’t in the documentation…or maybe I just missed it.
I found the reason that I couldn’t change the password. I was trying to use an underscore ("_") in my password to make it more secure. If you use an underscore in your password it will say “Wrong password!” and will not let you change the current password to any containing an underscore. Not sure how many other characters are not allowed, but this is silly and it undermines having a more secure password. Anker should allow all printable characters as passwords and (although I haven’t checked for the number of characters limit yet) the password should be allowed to be up to 256 characters.
Thanks @Nhi, you are a life saver! Hi @bill_rae, to better reply your question, I suggest you contact us via support@anker.com, my colleague will glad to help you.
Awww I see. It would be nice if we could rename our Wifi network too. But I am very happy to see that they had an update for the dash cam recently. I hope more updates will continue coming out in the future.
I would like to suggest a Sync button or download all button to be able to grab all videos and review on phone later. It would be nice to just hit one button and let it rip
Hi @bill_rae, the sensitivity for gravity helps to detect vibration and shock while driving and makes DashCam to respond appropriately. And the parking monitor enables to keep DashCam in standby mode. Hope I make myself clear. If you still have any doubt, we recommend you contact us via support@anker.com or support@goroav.com.
yes thanks, i forgot about the sensitivity while driving, i believe its for recording accidents and locks the clip correct?
Correcto! I love that feature, otherwise, you’d have to manually push the EMER button to lock that footage so it doesn’t get overwritten when your memory card fills up. Besides that, how many people would remember to do so when in an accident? Good thinking Anker 
But let’s hope that we’d never have to actually go thru getting into an accident.
A few UI improvement suggestions based on my couple weeks of ownership. These are in order of my perceived value add.
The emergency button is very difficult to get too, especially if it is tucked under the rear-view mirror like mine is. The on/off button however, would be a great, easy to hit, emergency button. A short press could trigger emergency/lock, a long press could turn off. Assuming this button is simply tied to a GPIO, that should be trivial to implement.
I agree with the poster above about the the parking monitor falsing on the door open/close. Perhaps a dead-zone setting option in the parking monitor would be sufficient. A default of +/- 30 seconds from power on/off. This should prevent most door open/close false triggers.
It would be nice to have an indication upon entering/power on if there were any issues during the parking segment. Turning on the screen, and displaying a large number (or beeping) or some other indicator to inform the user that the parking monitor was activated while away. Bonus points if the time/date/sensitivity of the impact(s) could be displayed.
Although, the way mine is tucked behind the mirror, a series of beeps on power on might be a better option b/c it is difficult to see the screen w/o moving my mirror completely out of the way.
And finally, it would be fantastic to be able to use the device as a wifi client on my network. This of course would take a fair amount of effort, but it would be much easier to pull/view videos. Not much ROI on this feature – it’s only neat. Perhaps a compromise would be to auto-enable wifi for X seconds after power so a phone could easily connect and see if there were any issues during the parking segment.
The nerd in me hopes the f/w is still in active development. This is a nice little camera. These updates would be worth a couple of dollars donation.
I wonder if anyone has built a custom f/w for this device? 
Anker needs to offer an rear view mirror mounting option for the Roav… For some vehicles (and purchasers), mounting to the windshield is simply not a desirable or practical method.
I’ve only had mine for a short period of time, but it became apparent pretty quickly that it would be quite handy if Anker included a storage case of some type, or at least made one available as an accessory. In many areas around Chicago, leaving a Cam in the window is just asking for trouble so I frequently need to take it down. Without any type of protection for the lens, I’m thinking this lens is going to get destroyed in short order. Suggestion box stuffer! Thanks.
Thanks for your suggestion! We’ll consider your advice and keep improving. Thanks.
i get a lot of people who ask me if it is a stock camera. I have a ford f250 lariat. I say no it’s an Anker
I did lie and say it was recording all the time so they wouldn’t mess with my truck
One other item I forgot to mention, an additional suction cup mount like Aukey is providing in addition to the hard mount.
just getting to grips with this new piece of kit… and have some questions that i can’t see answered anywhere.
We are using the ROAV in our camper van and the power socket stays live at all times. So the camera would not necessarily switch off when switching of the engine or on when starting up…. Is that correct? Is there anyway to ensure it powers down after the vehicle has been stationary for a given period anyhow? Does it actually do this anyway? Equally for starting up, given the power might always be on, then does it draw some tiny amount of power all the time, or does it need to be powered up to start etc.
Thanks for your help etc
If the power socket stays on all the time, then I would think that when the dash cam is connected to it, it would continuously record (loop) for the time frame that you set it at… for instance 3 minute clips. With my car, a Toyota RAV4, the dash cam is only powered on IF I have my engine on or I have it hooked up to a power bank. Meaning, I can have my dash cam plugged into the charger but if my engine isn’t on, the dash cam will switch to the “Parking Monitor,” and utilize the internal battery…in which, it takes 30 second clips and saves/locks onto your microSD card every time it comes on.
On a side note, regarding the Parking Monitor… I’ve found that even when I have it turned off. It still somehow comes on. Which is annoying. Hope this helps. If nothing else, call Roav. They have excellent customer service.
Help! Help! My dashcam screen stays on while I am driving.
You have the option in the dash cam menu to turn the backlight off after either 30 or 60 seconds of use. It sounds like you have currently got it set on off.
WHENEVER I cut on the car (even if parked and not moving) the dash cam makes a noise and goes into emergency recording mode. When I’m driving or not driving at all. HOW DO I SHUT THIS OFF?!?
I have the parking sensor off and the other one. (I forget the other setting) it’s so annoying!! Even if I turn the cam off while I drive, the battery backup kicks in and it turns itself back on.
It will make the noise and stat emergancy recording, I’ll hit stop, then 4 seconds later it goes back to emergancy recording
