There is no need to attach an electrostatic film. Under normal circumstances, the electrostatic sticker used for driving recorder is not firm, because the driving recorder is installed on the front windshield and exposed to the sun for a long time, and the driving recorder has a certain weight. The main function of the electrostatic sticker is to facilitate tearing, so its viscosity is not high, and it is generally used to paste small and light things such as traffic insurance. For the driving recorder, you can directly tear off the 3M glue on the back and stick it on the front windshield.

Moreover, even if the driving recorder uses electrostatic stickers, it must ensure that there is no dust, no other stains and it is dry, just like the mobile phone film, so that the electrostatic stickers can play a very good role. However, it is inevitable that the vehicle will bump during driving, and the electrostatic sticker will not stick firmly because of bumping, and it will also be unable to bear the weight of the driving recorder because of the adsorption capacity of positive and negative electrostatic charges. So it is better to use 3M glue directly.

Ways to make the driving recorder stick more firmly;

1. When installing the driving recorder, wipe the place where the front windshield needs to be installed with a soft towel. There should be no water in the place where the taped driving recorder is installed. You can blow the tape with the air duct first, so the effect will be better.

2. The suction driving recorder can wipe some water on the suction cup and then stick it on the glass, so that the adsorption is more firm. Glass glue can also be used between the suction cup and the front gear, which will be stronger, but it is also more difficult to disassemble.

3. You can choose to buy and use a bracket-type or rearview mirror-type driving recorder, which can be installed on the rearview mirror and fixed with buckles or elastic bands. Compared with sucker and sticker, the installation is simpler and firmer.
