Is the external battery of recorder useful?
Some recorder built a small battery, can continue recording hours at a time out of the rear of the vehicle, many businesses will also be described as the function of parking guard mode etc.. But because the shooting angle is fixed, so the recorder has helped to determine the traffic accident occurred after running in responsibility, and there is no direct help for anti-theft simple parking later, so we think this some words are icing on the cake, there are of course better, even if not to also do not deliberately pursue.

Emergency saving function is a function of many recorder have after the accident, when a button is pressed, it will automatically save the video one minute before and after the keys, and the video will be stored in a folder, even if the storage card full record will not be the top off. But in our experience, this function is close, but once the accident, because few people seem to be the first time press this button, often three five minutes or even longer time, just the reaction come over, but it was too late. Some friends even press time will also worried that if not the situation.

Of course, part of a recorder will built a gravity sensing module, when the collision occurs through the induction to automatically save the video, than the relatively preserved function to ease some of the manual.So we think this may not be as important conditions of purchase recorder, this function is best, does not have this function also need not too care about. Also suggest that you travel more prepared stored on a card, in case of accidents can replace a new card to store, don't worry about the video of the accident may wash.

In order to win market recognition, many high-end vehicle traveling data recorder in meet the video recording function, a lot of new functions, such as navigation, electronic dog, lane departure suggest, even the gravity sensing and other advanced features, these high-end features can help product considerably, but for consumers, the purchase should first consider the basic video recording function meet, then according to choose another configuration requirements.

Typically, installation tachograph into paste and suction cup two, two ways are also very obvious advantages. Through our experience, the gluing mode more firmly, but the adhesive to way has drawbacks, unable to move, if needed in different vehicles for the use, I'm afraid not quite convenient.

Chuck is relatively flexible, convenient installation and disassembly, but chuck at high temperature in summer and low temperature in winter may have the risk of shedding, firmness and chuck is adhesive or slightly worse some.The installation method of recorder, general specification for a product will have detailed introduction, the installation requirements are basically the same. Space permitting, priority selection rear-view mirror rear position, here is located between vehicles, record the angle will be more accurate. Position not too close, otherwise easy to block the driver's line of sight.If the space is limited, to the right and left sides trimmer is also possible, but not the location too far, otherwise will not accurate shooting angle. Not even the convenience, the recorder installed in the windshield on the left or upper right corner, that is not of any significance.
