Question: How long will it record on a 32 gig SD card without overlapping?
Document: This recorder is just simply awesome!After making research all over the web I decided this is the best,and for $89 its a bargain..I received it last week and it did not disappoint me! !Took it out of the box, plugged in, popped in the SD card, and it was ready to record. I love it!
Maybe if they throw in an SD card and glue the rubber feet on, it would solve the main issues. I'll keep an eye out for this happening, and will update if I do end up trying them again.
It takes a little patience learning the features and you are locked into having a smoked review mirror. Solution is simple. Hang onto the booklet and the smoked mirror works just fine for me.Pros:Shoots really crisp/clear video from both camerasInstalls easyNice long power cordDoesn't hinder my view (despite some others claiming)Uses cheap SD cardsHAS INSTRUCTIONS!
It takes a little getting used to and having a mini-van, which plenty of blind spots, made me worry a little about having a diminished view behind me. However, it was not enough of a problem for me to take it off.There are plenty of options, resolution, how quickly does it cycle through and record over older video, how long should it stay powered after the engine is shut off, etc.
Really impressive video performance for the price, especially in low light. It has two cameras that can be swivelled independently so they both face the same direction or in different directions. The cameras are really easy to grasp and rotate, and they have a ratchet-type system so they click and stay where they are positioned.It records video on an SD card.
You&#8217;ll see Date/Time, Auto Power Off, Deep Sound, Language, Frequency (SD card, 50 HZ or 60HZ) Format, Default Setting, Lights Up (Day mode or Night mode), Date Stamp, Screen Saver (1 to 3 minutes) , and Version (1.00).
Hold it down for a couple of seconds in order to enter the menu. You&#8217;ll see Resolution, White Balance, Loop Recording, Audio, and Video modes. It&#8217;s recommended, although it takes up more storage on the SD card, to turn the resolution all the way up.The loop recording has three options:  Off, 5 minutes, and ten minutes.
The image itself will only stay up just over 1 minute unless you manually hit a button to remove it. You can set it up to be in dual camera mode or single camera. Besides videos, you can even take pictures. Everything is stored into an SD card (not included). The recorded videos are continuously looped. However, if there is a video that you wish to save, you just hit the Menu/Rec button and it is stored on the SD card and will not be recorded over.
Terrible. Since camera is attached to rear mirror you can not adjust  vertical aim of camera without adjusting aim of the mirror. I need the use of my rear mirror, so this is a very bad design.
The 3.5&#8221; screen is a definite plus, and I will tell you why; DVRs without this feature, make it very difficult to see what exactly the camera is recording, or in this case, &#8220;camera&#8217;s&#8221; plural.
Answer: About 8 hours @720p with both cameras on (A+B)
