Theres something I notice about these dash cams and their reviews.
The night time videos they post are always in street lamp lit areas. Been looking for a long time for one that has substantial low light performance because of the unlit nature of the majority of the roads here as well as being rural that limits light pollution to a non factor.

Perhaps I am asking too much, but expect ISO 12000 or higher to get any quality detail from the headlamps (tested with the SLR at 25600, f2.8, 30th/S and it just extended beyond what my own eyes could see in DX mode, in FX it does a lot better using more of the sensor for 1080p).

Then there is the lack of rear cams which I think is becoming increasingly important with smash for crash or just those that get up your Jacksie showing pre-meditation.
Sure we have all had one that gets up the back end swerving all over or appears in the mirrors overtaking 6 or more motors on a narrow winding road.

You make some good points...I think it's hard to get an increase in low-light cameras without increasing the price substantially to get that bump in tech. Also, I didn't even think about having a rear camera for situations like that; with luck if you get bumped the person will have a license place on the front of their car to catch that fool!

Well I live in the Dark Sky Park,,,,, Where half the roads are gravel tracks,,,, I know cruddy driving conditions :mrgreen:

Speaking of low light, the person who invented the CMOS censor pretty much all cameras use nowadays (being cheaper than the former CCD, though frankly the colour reproduction has never matched in my honest opinion), has supposedly just discovered a way to make a chip, that would be directly swappable with the same electronics, that can create a signal with a single photon.

Now thinking to me taking photos of the starry night sky, a wide shot looking at about 20 seconds to get a decent exposure to see the specs of light, and taking thousands of photons to come close. If I were to say this could do it on 1/1000th we are talking a camera that can see more than your own eye in about 100th of a second. The standard exposure on a video is either 1/30th or 1/60th in bright light.

Just think about that and the possibilities :geek:
Could be talking HD clarity in near pitch black!

But, talking several years before we even start seeing it in full production.

Now that is pretty damn impressive! I'll have to take a look into that, what's their name?

Something like that would surely take years before it reaches mass production and another year or two before it hits the consumer level...can't imagine what that would cost, couple of pretty pennies I'm sure.

Thanks for all the input!!

Both my DSLR's are CCD, but they both suffer with noise over iso 800 too.

Looking at getting a new one this year...maybe...

Have had a Nextbase for a couple of years.
Battery now doesn't work unless it's plugged in and it doesn't like keep cutting off.
Sometimes has card read problems.
Was this one:
http://www.halfords.com/technology/dash ... 02g-deluxe

Now, these GoPro copies any good?

http://www.ebay.co.uk/sch/i.html?_from= ... 000&_sop=7

If not then would spend a bit more money.

If you buy a copy you risk it. Might be good, might not be. I've got a genuine SJCAM which is a copy of a gopro but a good one at that. They are decent. There are copies of the SJ which are and ones which aren't.

Any cams with Aux feed from rear camera? My current one does but the camera is not always reliable in recording so would like to swap it out but also keep the rear camera.

This current one

Don't think I'd get another Nextbase.
The battery doesn't work at all now.
It shuts off when you turn ignition off....then comes up with error message.
It just trips it out, need to remember to turn it off before turning ignition off.

You don't until you open the box and use it. That's why it's a risk.

Disgruntled_Knome, I've uploaded a night video of me driving through some unlit country lanes. There was intermittent rain.

The Cam is an SJCAM M10 recording in 1080P @ 30FPS. I've trimmed the file to 1:20 and it works out at 124mb.

https://www.dropbox.com/s/fv9m893ppjkgy ... t.mp4?dl=0

This camera cost me £45

I'm currently testing a Thinkware F750. It does motionsense (the Aston that was keyed in the news had this unit fitted) continuous recording, lane departure warning, forward collision warning etc. Very nice piece of kit.

Just had a look at this myself, looks very good, looks similar to the ones we have in our lorries at work, will take a closer look on Monday, most of them are held on by tape at the moment, Halfords seem to do a good deal including installation, would definitely give it a go had I not already got one that does the job nicely.

I know these are at the higher cost end of these cams, but I have the Garmin which does speed camera alerts which is good. The quality is HD and very clear.

I e got a next base camera in my taxi, paid about £45 from halfords and it's very discreet.
No doubt the more expensive ones give better quality but this one has provided some entertainment to the family when playing back some of the antics on the road these days

http://www.racshop.co.uk/sat-navs-tech/dash-cam/product/thinkware-f750-dash-cam-with-rear-camera.html

Just bought one of these - Seems to do most things. Arrived yesterday so not had a chance to install it yet.
I got fed up with cheap chinese which whilst quality of video was good on HD they did not record reliably enough.
I am unsure how it records 10secs before impact collision when you are parked unless it uses motion detection? hmmm.
Can also be used with smart phone wirelessly and i beleeive the front and rear cameras can be connected wirelessly.

I got my Rexing V1 set up today, pretty chuffed with it for £40.

Here's some very boring test footage - change it to 1080p for the best quality version: https://www.youtube.com/watch?v=9LxNO4wg-go

Because of the shape of it it's seriously discreet, I can barely see it from my driving position and even from outside you probably wouldn't even notice it. I've mounted it ever so slightly too high, which is why you can see a few of the dots on the windscreen. I'll get that sorted when I can be bothered.

I haven't tried it at night yet so not sure how it'll be when it's dark.
