Thanks for posting this
@Jon Chalk.
I'd pretty much decided I was going to get a dash cam when I next got a car since the time my ex-wife's car was written off by a truck reversing in to her (whilst doing a u turn where there wasn't space) and then claiming it was her fault. He admitted fault in the end but a dash cam would have made the whole process much simpler and easier. Plus I'll be driving on some busy roads and I've seen enough idiotic driving nearby to want some evidence should anything happen.
In case it's of use to
@loggamatt anyone else, this is what my research has lead me to.
I'm planning to get the Blackvue DR750X (two channel version) because it seems to be well regarded and amongst the most slimline around. I'll also likely get a battery pack to extend the 'parking mode' on the camera and protect the 12v battery. The X series has a couple of advantages - it has low voltage protection built in (you set a voltage where the camera will shut down to protect the 12v battery), rather than requiring an external device. It also uses a three wire connection to the fuse box (or battery pack) to detect when the car has been parked and it should switch into 'parking mode', rather than relying on the G sensor.
There is the DR-750 LTE which has the LTE connectivity built in, but this is effectively the previous model so doesn't have those two benefits. So I might get the external LTE module, there is a very good bundle deal from one retailer. That at least gives the advantage that if someone breaks in the camera might have the chance to upload some footage to the cloud before it disappears. Or, far more likely, you'll get an alert if someone bumps in to your car. It sort of works as a tracker too, although a pretty easily defeated one! Blackvue have a deal with Vodafone for 40GB of data for £4 per month, so cheaper than running a separate dongle- although the Blackvue battery pack has a USB socket so you could run one from that for multiple devices.
The only complication with using the X series with a battery pack is that they only come with a two cable for connecting to the dash cam. However if the X series is connected this way it won't know that you've parked and left the vehicle, so you're wiping out one of its advantages. There is a three wire cable that can be bought to run from the battery pack and join on to the the dash cam's own power cabe that will make this work. The battery pack will be either the Cellink Neo 6 or Blackvue B124X (if you buy from the right place there isn't much difference in price), effectively the same battery but slight external differences and their own apps.
It won't be a cheap setup, but given how much I've factoring it in to the overall money I'm putting down on the car. Given my own cack handedness I'm planning to have it installed by a professional. There are some good bundle deals around and they include a CPF for the front camera at least, so given
@Jon Chalk's experience today that's a useful thing to have included.
One thing I have read about - Blackvue sell their own Micro SD cards at incredibly expensive prices, which I'm not going to buy, although I am going to get a larger capacity one. For the best chance of avoiding issues the advice seems to be to look for the Samsung High Endurance or Sandisc High or Max Endurance cards, which are engineered for use in security systems / dash cams.
