A:AnswerHello!
Yes! However, due to the nature of OBD ports, they are designed to always emit power, even when the vehicle is off. Due to this, if you are not careful, it is possible it could drain your vehicle's battery as it is always receiving power. This is vastly different than a normal hardwire kit as it connects to your vehicle's fuse box and it will not have this potential risk.
A:AnswerHi, If you wish to not use the cigarette lighter charger, you can hardwire your device using the Smart or Intelligent hardwire kits. With that hardwire kit, you can use parking mode, which will turn your camera on if it detects motion or vibrations (depending on which hardwire kit you own).
