Customer Ratings & Reviews

I’ve been using the Dual Intelligent Hardwire Kit with my Rexing dash cam for a few weeks, and it’s been excellent. The motion detection is quick and reliable—it starts recording right away, even when the car is parked. The built-in low-voltage protection gives me peace of mind knowing my car battery won’t drain. Installation was straightforward, and the long 13-foot cable made it easy to hide the wiring neatly. A great choice for anyone who wants hassle-free parking mode monitoring.

This is a cool addition to dash cams smart parking sensor (where if the car is bumped the camera will turn on). Now you also get motion detection in case someone is doing something weird around your car it will kick your camera on. It works really well. The only downfall I have is that these clips usually go into the "locked" folder, so eventually you need to format the card to get rid of these locked clips. But with a big card, this gets pushed way out to the future and probably good to do once a year anyway.

Excellent product - simple installation and works right out of the box! Had my dashcam installed right under my headliner, next to my mirror, and I put this under my mirror a bit in the center of the windshield since it needs to hang down. Run some simple cords and 10min later it's done. Works great and you can hear it turn on! Would recommend to anyone.

What an upgrade to the original Intelligent Hardwire Kit. Much easier to install and more robust. I like the fact that it even feels better made and is more compatible with any of the Rexing cameras we have in our vehicles. I was able to do a temporary mount and try it out on 3 different systems and all worked flawlessly. I'll be purchasing two more to install on the other two vehicles.

This is a very nice addition to the dash cam I installed. Works well when in parking lots and at hotels. Very easy to install. Would recommend this to anyone with a Rexing dash cam.

I recently picked up the Dual Intelligent Hardwire Kit for my Rexing dash cam, and I couldn’t be happier with the purchase. This kit is absolutely fantastic and has taken my dash cam experience to the next level! First off, the installation is straightforward. The included wiring and connectors are high-quality and feel solid, and the kit is very easy to set up with easy-to-follow instructions. I was able to hardwire my dash cam in no time, and the results are impressive. What really stands out is the intelligent power management. This hardwiring kit is equipped with a built-in voltage protector, ensuring that my car’s battery doesn’t get drained, which gives me peace of mind knowing the dash cam won’t affect my car’s starting ability. The kit also offers both Type-C and Mini-USB compatibility, which is super convenient since it covers multiple Rexing devices. Overall, if you want to keep your Rexing dash cam running 24/7 without worrying about your car’s battery or charging cables, I highly recommend this product. It’s a must-have accessory that works seamlessly and enhances the overall functionality of your dash cam. For anyone looking to install their dash cam permanently with an easy, safe, and reliable setup, this is the kit you need!

I've paid to have two dashcams installed, but was able to install this myself. Works as expected - no issues.

I own 2 Rexing dashcams and i couldn't be happier with them. This wiring kit is genius. Super simple to install and the sensor function is outstanding. Highly recommend.

I have a rexing dashcam and wanted to ensure that it would be able to capture an incident when the car is off. This smart intelligence hardwire kit fit the bill perfectly. It connects to your OBD2 and the installation is very simple. I have tested it for over a week now and can say that it does its job well!

I recently installed this accessory to connect with my Rexing Dashcam and I couldn't be more impressed. The setup was super easy and this kit comes with everything needed to start using right away. This is like adding additional peace of mind because you feel more protected even when you car is parked for long periods of time. Great addition, highly recommend it.

I have been enjoying this addition to my Rexing dash cam. I had the cam plugged into the cigarette lighter but that would stay on for over an hour after the truck was locked which I didn't like. I was always wary to wired in a kit to power the cam so I just left good enough alone but with this kit all I had to do was plug this adapter into the OBDii port and rout the cable up to the cam. Could not have been easier and only took about 5 minutes. So far this has been working very well, the camera turns off but when motion is detected the camera turns back on to capture whatever triggered it. I appreciate the feature to have the camera stay off once the battery voltage falled below either 12.4, 12, or 11.8 volts so no worries about a dead battery. I love the Rexing eco system and have always been happy with there products!

I'm a long time repeat Rexing customer. I've used several of their dash cams and all worked well. The quality is very good and customer service is extremely responsive. This particular product was installed by a shop since I'm not comfortable installing this type of hard wired electronics. So far it is working great and up to typical Rexing quality. I'm happy with the purchase !!!!!

So basically this device is an add-on to an existing dash-cam that can turn it into an external security camera when parked. I haven't tested it completely - but the install process is a bit wonky which could easily be avoided had someone re-thought the install process from a non-professional. 1. The instruction manual was great with pictures, but the QR codes and website that's listed in the manual take you to a much older product that requires you to hardwire the power to a fuse box in the engine - which is not this device at all. Note: There is a selector switch on the sensor which I'm assuming is for how much power it can draw from the battery? No clue. There's no information about it. I left it in the middle. 2. To provide this constant power - there is an included ODBC connector and a lengthy cable that powers this unit. I don't recall seeing that on the product description - so if you have something else plugged in there (like one of those insurance dongles that monitors your driving) - this device won't work. 3. While the power connector cable is long enough to attach this sensor hub anywhere - the USB-C cable that goes to the existing dash-cam is not. So if your dash cam is on the driver side and this hub is mounted on the passenger side - you'll have cables drooping above the rear view mirror since there isn't enough slack to tuck it in. 4. There no included car wedge device tool that you can use to pry back the seals and tuck the cables in. On a real positive note though - you now no longer need the cigarette power adapter because the hub feeds power to your dash-cam. The one thing that I didn't consider - but others may - is that if you only have an outward facing dash-cam. It's only going to record the front. This unit would be far better for one of those front-rear and internal dash-cams - to have a better chance at recording something should something bad happen to your car. Of course, unless your dash-cam uploads automatically to the cloud - all someone has to do is take your dashcam/sd card - and it defeats the whole purpose of this unit. That said - this is an interesting unit - and shouldn't deter anyone from getting it - just know what it can/can't do to manage your expectations.

Installation was easy as advertised, and now I have more peace of mind when leaving my car parked in an unfamiliar area. My Rexing dashcam from 2020 still working just as well 5 years later and now I'm glad to get this extra upgrade!

The Rexing Intelligent Hardwire Kit works exactly as advertised. Installation was straightforward, and I appreciate that it comes with everything needed to get up and running quickly. My dashcam now powers on automatically and continues recording with parking mode after I turn off the car — no more worrying about a drained battery thanks to the built-in voltage protection. It’s a clean, set-it-and-forget-it solution that keeps wires out of sight and the camera running reliably.

The kit works as described with proper installation. I found that the sensor performs best when mounted in the center of the windshield, where it has the optimal angle to detect motion. Keeping the windshield clean is also essential, as dirt or debris can interfere with the sensor's accuracy.

Just added to my car for additional safety. It did what it intended to do. The setup was easy and very well hidden behind the mirror. Good so far.

The idea is interesting, instead of the camera activating when the car is hit, this will turn the camera on for a few seconds if it detects movement. It also has a voltage level setting to prevent draining the battery. It includes power cables for both charging types of Rexing cameras. The unit gets its power from a ODB2 connector. My only issue is it does not come with a hardwire option. I can see this being included in future Rexing cameras.

I have been using it for few days and it works good. I wish there was a more detailed specification on how it works, at least I did not find it. But I got that answered by Rexing customer support.

Tested it in a parking lot. It detected each time moving object approaching, and started a recording about 1.5 minute or long depending on how long the object was moving around. A great ad-on gadget to your dash cams. Haven't tested its compatibility with other brand, but it works very well with all my Rexing cams, even with the dual cams supporting front and rear cams. It has to be powered by the OBD port, so if you already have a device connected to OBD (like some GPS tracker devices), you need to either stop using that device or buy an OBD adapter to support both. Very easy to wire and install.
