Leakage Seconds refers to the process of vehicle video recorder to record every 2 videos while there will be 1 second later can't be recorded.
The reason is for that the car dvr likes a DV camera. Now a lot of vehicle traveling data recorders adopt the circular mode. Generally, a 4GB card can record 720P video for about 30 minutes. You will need to use the video technology to record and delete data which recorded half an hour before. So it needs to frequently read/write memory card data, but different memory cards have different highest reading speed. When the memory card reading and writing speed is too slow, it needs to stop recording to read and write data, so there will be a leakage seconds occur. Of course, not all of the car DVR will appear leakage seconds, you can avoid it by choosing famous brands and high-speed memory card to realize full recording.

It is very simple to test whether it has a leakage seconds or not. To record videos with the car DVR facing to a mechanical watch. The moving range of a mechanical watch’s second hand is less than a second, and then set the video time for 2 minutes, namely 2 minutes to video play a package. We can set the recording time at 2 minutes, which means to store every 2 minutes. Then we use the video software to connect two 2-minute files an play it, we will find between two files the time when the time jumps from 23.12.39 to 23.12.40 in the recorded video, the watch’s hand crosses 5 seconds distance during a second. What happened? Is this time from two different world?

In fact, this is the leakage seconds. Some manufacturers will use some methods to deal with the time problem, to make it look like no time missing but in fact there will miss 4-5 seconds during recording. This is the reason why recording time is one second and the watch time is 5 seconds.
And why is 5 seconds leakage, why want to cheat, it is very simple.
It dues to the chipset performance, for it can’t compress the videos to save while recording. The leakage seconds is the time that it stops recording and spends 4-5 seconds to save the recorded video, an then record again. So this cause the video lost.

So we suggest you to buy a high quality car dvr for your car.
