Welcome to the forum ticomque.
All dashcams need power all the time when in operation , generally coming on when you turn on the car and so the power source ( often the in dash 12 V socket ) turn on.
What you have is a action camera, granted these often have dashcam functionality ( coming on when power is applied by wire ) but the battery in it will probably die soon, CUZ low temperatures,,,, and high too are not good for LIPO batteries.
Also it appear that the camera is just a 720 P resolution, which all serious brands abandoned over a decade ago, these days 1080p are barely recommended.
If your in dash 12 V power source are on all the time, and it seem some cars have it this way, well then your camera would also be on all the time and that would be bad for camera life, not least in high summer and its heat though it should shut down on too high temperature.
Your product seem to be a very old one, so probably abandoned by vivitar long ago, it is not a brand that see much action in here, in dashcams or our action camera section.
Some dashcams do have batteries for emergency power, but we do recommend people look at cameras with capacitors for that purpose ( and that is just finishing last / current file in case of a big event ) the in camera power source are not really meant for recording in general, this is always provided by wire from the car.
