BESTEK Dash Cam Hardwire Kit with Motion Detection Sensor, 12V 24V to 5V/2A OBD-II Dash Cam Hardwire Kit with 9.4ft/2.85m Wire, Low Voltage Protection Compatible with Mini USB Dash Cams, GPS Navigator

I needed a hardwire for a mirror dashcam I bought, since the original charger was a cigarette lighter plug (like most) and that was not adequate for me since it tends to drain car batteries within a short period of use. With this hardwire kit I found that despite having the car untouched for 3 days, it worked very well without draining the battery.In fact, I find it works too well since it records even the slightest movements such as trees blowing in mild wind. I find that very useful the most since I leave it parked in some areas where incidents are bound to occur.Upon having this item for about 3 weeks, I found that:-The adhesive works well and doesn't budge-It does not drain the car battery despite not turning on the car in a while-Motion detection is very sensitive-Fits most dashcams so long as they use the mini usb port.-Easy installation, due to only having to plug into the OBDII port and hiding the wireI would definetly recommend this to anyone who needs a simple hardwire for their dashcam, and will update if any abrupt changes occur with this product.*Update as of 7/30/20*- The product still seems to be working fine- Adhesive has not diminished and is still strong- Is still as sensitive as previously mentionedOne distinct difference I have noticed, is that it MIGHT not prevent battery drainage. Due to the recent issues, I have left my car unattended for some periods of days/a week. Doing so seems to leave my car battery drained and unable to start. Will update if can confirm it is indeed the motion sensor.FINAL UPDATE (1/8/21)After finding out I had a bad battery, it turns out this device simply either lost it's functionality or lost it's range in detection because it barely captures any movement now unless it's me opening my car door or closing it. Worked very well the first months or so but now it's just an alternative power unit for my dashcam whenever I'm driving

I made a good decision to buy this obdii dashcam power cable. I replaced the original in car 12v power socket cable and it provides constant power to my dashcam. The motion detection is very sensitive. Even I knocked my side window and rear window, it will wake up on my dashcam and start recording. The installation is super easy. Just plugged into the obdii socket and it will work right the way. As long as your dashcam is powered by mini USB and dashcam park mode is set. It will automatically work when your car is turned off. I had my car parked on the street when I was in my 2 weeks vacation. It was triggered by multiple reasons and it didn't drain the battery. Highly recommend this productThe cable provides the same functions as the other high price product.

Bought two to test them out on two of our 4 cars. Hated having to use up a cig lighter plug or USB port to operate and hated having the wires dangling down. The only thing I would say is it would be great if it came with a micro usb to mini USB adapter as one of the cameras I have uses a micro usb. (I may be saying that backwards). But I just ordered some small adapters and plugged into the camera and it worked. Motion detection works good. Camera takes about a minute to turn off after you turn the car off. Easy to run the wires and plug into the ODB port in the car.

I liked the idea of having a physical switch in case I wanted to shut the dashcam off, but this unit is randomly turning my dashcam off for a few seconds, then back on...repeat repeat.Hate to give up the motion detection part, but I'm afraid it will shut the dashcam off at a critical time. So I plan on replacing it with a hardwire kit that goes to the fusebox instead.

I like the fact it has a on and off switch, but one thing I have a problem when you plug it into the OBD2 and the cable is in the way, over it is the best thing I ever got.

Works for what i need it. Make sure you know the OBD port has constant power so whatever you plug in will always be powered. There is a switch to turn it on and off

This sensor is pretty good, though things like sudden light changes from distant cars or even the sun and clouds have set it off while it's missed some people and animals. Overall decent for the price.

The motion detection doesn't seem to work properly or is too sensitive, the camera is always on and i so for a 32gb card i have stored only 2 hrs worth of video. I'll probably end up having to turn off the device because I don't drive the car everyday and it was slow to start this morning after not driving it for a week. I had intended for this to turn on the camera in an event bump or accident when the car was parked, it doesn't as intended. The camera didn't save anything as read only, so even if there was a hit and run and the cable had worked as expected, the video could be recorded over after about 2 hours stored as HD video on a 32GB card. For now I end up turning off the device so I don't drain my new car battery

Worked well for the Dashcam in my husbands truck.
