    Are there any 2 channel dash cam with both lenses remote

    I was looking around and found something from Axis that is basically my dream setup as far as this sort of remote lens system goes: https://www.axis.com/en-us/products/axis-f-series I have no idea how many megabuck$ they want for their system, but I am still holding out hope for a good system...

    Are there any 2 channel dash cam with both lenses remote

    I got my other cam working again, but I'm still interested in this.

    Are there any capacitor-based power banks that don't use batteries?

    I ordered a Noco 5w solar panel and I'm going to see about mounting it on my trunk lid with VHB and see how much it helps. It was only $40 on ebay, no harm in trying. Supposedly its waterproof, I guess we'll see how well it holds up to highway speed driving.

    Are there any capacitor-based power banks that don't use batteries?

    It's a Qvia AR790 2CH and it has a direct 12v connection, no separate power supply.

    Are there any capacitor-based power banks that don't use batteries?

    Unfortunately my parking spot is far away from power, but since my battery is in the trunk of my car I am going to look into a solar panel on the trunk lid. I wonder if suction cups would be strong enough?

    Are there any capacitor-based power banks that don't use batteries?

    I contacted my local Maxwell distributor to get a quote on their new 3v 3400f caps, and even in quantities of 150 their price is just under $70 each. So this would be super expensive, to boot. My car already has an AGM battery from the factory, but have to go on an occasional 30m drive to keep...

    Are there any capacitor-based power banks that don't use batteries?

    Sure, but that doesn't really solve the specific problem that I was targeting - it would charge a little bit, and then discharge a lot, and then charge a little bit, and eventually discharge completely. Current battery tech requires long idle or drive sessions in order to get them charged all...

    Are there any capacitor-based power banks that don't use batteries?

    Good idea - will look into solar panel options.

    Are there any capacitor-based power banks that don't use batteries?

    Ok thanks for doing that calculation. I didn't think the density was quite that bad. I guess that would take up the entire trunk of my car, so that wouldn't be an option. Oh well.

    Are there any capacitor-based power banks that don't use batteries?

    No I'm serious, I do know that it would probably be the size of a group 24 lead acid battery, I just wanted to know if anyone had made one already.

    Are there any capacitor-based power banks that don't use batteries?

    I'm interested in knowing whether anyone has developed a power bank that has only capacitors inside, instead of being based on batteries like usual. I know it would take up a lot more space for the same capacity, but the reason I want this is because it could charge completely during a short...

    AR790 2CH bricked after failed fimware update - fixes?

    @redler Your suggestion worked perfectly! Thanks so much! I'm still looking forward to the SG9663DR to replace this thing, I think it should be more reliable and have better support.

    AR790 2CH bricked after failed fimware update - fixes?

    Thanks for the tips. I will try it out for sure - I had been trying to use an SD with both the firmware and a modified config file, but I will try a freshly formatted SD with only the firmware on it.

    Are there any 2 channel dash cam with both lenses remote

    Well, it's been about a month since the 14th, just curious if you have any update available? Since my Qvia dashcam died and I have gotten zero response from their support, I really want a high quality 2ch replacement device - and both lenses remote would be the cherry on top.

    AR790 2CH bricked after failed fimware update - fixes?

    I tried updating the Qvia viewer to see if it was because of a bad config file, but the new config file did not fix the problem. Does anyone know how to contact Qrontech/Qvia?

    AR790 2CH bricked after failed fimware update - fixes?

    I tried installing the latest firmware on my AR790 2CH, but now it does nothing. I think the firmware must not have installed correctly. If I put the firmware on the card again and put the card in the camera, it says "Firmware update starting" and then goes silent and back to being a brick. Are...

    Any update on this? I'm interested.

    New “Instantly Rechargeable” Battery Deals a Fatal Blow to Fossil Fuels

    Flow batteries are real and work well, but they are impractical for cars at this time because they are 10 times less energy dense than normal batteries. If you have space at home for them, they do a pretty good job for stationary energy storage, and won't wear out like lead-acid batteries.

    Cam doesn't seem to loop record once the card fills up

    Well, one good reason to use MicroSD would be to plug it into my phone and read the files, but now manufacturers don't seem to be building in MicroSD support in phones either. So that leaves bluetooth or wifi connectivity, and neither of these ever work well on dashcams in my experience. My...

    Cam doesn't seem to loop record once the card fills up

    After taking the card out and saving a new config to it (did not format), I then put it back in and it started recording as normal and looping as expected. I took it out later to verify and did have some new files, but I ran chkdsk just in case and found no issues. So hopefully it keeps working...
