Question: Do you have to buy a memory card to get it to record ,or does it have memory if so how much???
Document: Buy a card memory when you buy the camera. You can estimate the size of the card with this tip: 30 minutes = 1.2 Gb
language always goes to ... who knows what. Manual is hard to understand. I wish that this DVR will record until I reach my destination or the memory is full.
No external charger came with it but found that a Motorola phone charger worked fine and quickly.5. Turns on and off easily with car ignition as indicated.6. Instructions shld. be written better by someone who has English as a 1st language but essentially they are saying: a. there is no USB port so you need to buy a card reader. b.
this black box do not have TF card.I do not know where I can get the TF card for black box.
You never know when this is going to happen because you can only see it when playing back on the PC. I would recommend just turning the unit on, waiting 10minutes for it to 'heat up' and get a strong satalite signal, then use the gps feature.As far as quality, it is certainly not HD. It's VGA. Cant make out any  license plates or details of any kind. Its pretty much just to capture a general event, and not worry about detail
For what it is, this is a great little DVR. I got mine, put in a MicroSD card, plugged in two wires, and it just worked. Build quality is much better than I expected, it feels like it's put together solidly. For the price that I paid, I was expecting loose fitting, thin plastic shell that creaked and flexed when holding it, this does not do that.Video quality isn't bad, although it is low resolution.
No real product support or website. After months of use I still have no idea what company makes this thing. There is no firmware updates. Disabling one of the cameras does give you hd. the camera mounts permanent as the connections are hard to get to and you have to disconnect the power to access the sd card. The cam does come with an external gps sensor that once connected often breaks when disconnecting.
Poor image quality battery life inexistent  won't buy it again and I would not recommend to anyone
Requires one to reconfigure memory chip with little or no instructions on how to do it. I had to return mine as it did not even work out of the box.
