Great stuff, keep 'em coming!
However, this length of data collection is important to us, since we are going to be running a 24 hour race, and I was wondering if the SD card was "hot swappable" with the unit running? or does the VVB need to be turned off so data is not lost when switching SD cards? thanks!
Also, is there a visual indication to the driver when the storage capacity is getting full? Thanks in advance!
MOST definitely not, if it is recording - you will corrupt the data, possibly for good. However you can swap media with the unit turned on as long as it isn't recording.However, this length of data collection is important to us, since we are going to be running a 24 hour race, and I was wondering if the SD card was "hot swappable" with the unit running? or does the VVB need to be turned off so data is not lost when switching SD cards? thanks!
Are you using a Pro or a Lite? On a Pro the memory indicator LEDs light up as the card becomes full. On a Lite there's no memory indication.Also, is there a visual indication to the driver when the storage capacity is getting full? Thanks in advance!
Remember that a 32gb card will give you about 15 hours of video
Thanks for the quick reply. It sounds like 2 32GB cards, and we would be good to go for the duration. The team is evaluating our options for in-car video now, so we don't own a product yet (we used a driftbox during our last race). The Pro package offer you are running is a contender!
With semi-frequent data/video collection, you can see if a camera has been knocked loose or review earlier footage of racing incidents while the car is back out on track recording more, so I would say it's a good way to go.

Hi everyone I'm new to the forum ...
I also have planned a 25 hours (Fun Cup at Spa), I believe that the solution in the race to replace the SD is always risky, better to have auronomia registration for the entire race. I would be focused on a hard disc anti-shock external usb type:
the cost is acceptable 60/70 € (320 GB), while a USB stick costs about 150 to 128 although it is smaller.
My only question is how to behave on the hard disk while recording and the machine vibrates and take branches from all sides, or even worse in case of accidents .... has anyone been able to test a HD?
Two things come to mind: I personally wouldn't use an external HD in a race situation - anything with moving parts in that kind of environment is asking for trouble, and solid state would be a better idea.
Also, if you're using a Video VBOX Lite with an external hard drive, the tank circuit doesn't work - the hard drive draws too much current.
Solid state media is advisable, and there really isn't any problem with swapping it over during driver changes, so I think that Jim's suggestion is the best bet
A 64GB or 128GB USB memory stick would be a nice option if you can afford it. Low power, no moving parts, no swapping media for many hours.
A SATA SSD in a USB-SATA adapter caddy might work well too - but even more expensive, at the moment.
Thanks for the useful advise about how to position the camera to get the right exposure.
My issue is that I was trying to get one camera behind the driver to take both the steering works and the outside view and another camera pointing down taking the foot work.
So by your explaination, I will try to position the camera so the interior view is minimum.
So it means there is no way to lock the camera exposure?
We used 2 VBOXs in 2 cars at the recent 24h race at the Nurburgring.
We had 16 GB and 32 GB SDHC cards, which we swapped from time to time. Although the recording time could be more than half of such a race, I would never take the risk to let the VBOX record unattended for such a long time. From time to time recording stops for unknown reasons, which is what you can cure by restarting after a card exchange.
Swapping cards sounds easy, however, in practice it isn't always that way. If the car stops, recording will stop after 2 or 3 seconds, which usually works fine. That would be the perfect time for the swap. However, before anybody can get to the VBOX, about 10 people are tearing at the car for a tire change, fuelling and other unnecessary tasks, which typically causes the VBOX to start recording again.
So you can't wait for it to stop because there is too much movement around the car. If you stop recording manually, you leave automatic mode, which means the VBOX won't start again after the pit stop unless manually started.
We have solved the problem by disconnecting power supply to the VBOX when the car comes to a halt, wait for the recording to shut down, and the do the swap. After power-up the VBOX will be in auto mode again.
Perhaps somebody has a better idea.
Potentially you could use an on/off logging switch with a USB drive. If placed close to the driver, he can then manually turn off the recording, remove the drive and then the incoming driver inserts his USB media and starts recording again.
Alternatively you could start and stop recording via a wheel speed or RPM instead, from CAN or a Micro Input Module.
