AZDOME M550 3 Channel Dash Cam, 4K+2.5K Dual Dash Camera for Cars Built-in WiFi GPS, 1440P+1080P+1440P Front and Rear Inside, 64GB Card Included, 3.19" IPS Screen, WDR, IR Night Vision, Parking Mode

I've been using this cam for a while now. It's pretty easy to use, and the picture quality is good. When videos are played back in the accompanying app, a map also comes up showing your route during the video, along with the speed limits of the roads you traveled, your vehicle speed, time, date, and GPS coordinates. It's REALLY THOROUGH, and would be a REAL HELP in COURT! The app also lets you pick which of the three cameras you want showing. About the only disappointment is that it doesn't automatically update the time, especially when going from Daylight Savings to Standard Time. This could trip you up if you're using a video for evidence, as if the time is wrong, the other side's lawyer could use it against you.The unit is really small, so it doesn't block your view. It's menu is pretty easy to use; basically UP. DOWN, and OK buttons to access everything, with no "hidden" menu items you need to "long press" to find.I haven't had any serious issues with the camera. It does have a couple of idiosyncrasies though:1. It will randomly not turn on when the engine is started. It's not a huge deal, as pressing the ON/OFF button will turn it on. It's a minor annoyance. The camera makes emits an easily heard tone when it turns on, so it's pretty easy to tell if it hasn't.2. I get random pop-ups saying "Please format SD card," with an OK and CANCEL choice. I'm not sure why it does this. I just do the CANCEL and go on with my life. If OK is selected, the SD card is reformatted and all recorded data is lost. I've yet to try downloading recordings from the SD card when I get that alert to see if the existing data is corrupted. I will update this review once I've tried this.3. If you're a ham operator, as I am, the camera interferes with VHF frequency 146.520 Mhz as well as its harmonics with a pronounced "motorboating" sound. This usually happens when the camera first turns on, and continues for up to a half hour. The QRM is strong enough that you can't squelch it out. After that half hour, the QRM drops the point where it's still there, but at a much lower level, rendering the frequencies useful again. I believe it has something to do with the camera's charging system. The camera uses what the manufacturer calls a "super capacitor" as a battery, so it discharges quite a bit between uses. I'm currently looking at running the camera through a USB battery bank to the power source to keep it under power 24/7. True, this will defeat the auto-on/off of the camera, but it may get rid of the QRM. It will also let the camera run in "Sentry Mode" to keep an eye on my car while I'm away from it. This normally requires a "3-wire adapter" for he camera, which is not included. I will update this review once I've tried this.

This was the most bang for the buck. This is the third camera that I bought from a different manufacturer I like the interior view of the car, the rear, and the front extremely clear I had the option to where I could take advantage of the security feature I did valet parking at the hotel and I was able to go back and see that nobody Violated my privacy or my car. I was able to see anything that moved around the car like a Tesla it was the best choice. The installation was perfect. It looks almost factory. I’m very happy with this purchase. It was easy to install as long as you follow the instructions.

Video quality is good. There is plenty of cable to work with. I was able to install it in my car very easily.I no longer have my car so I put it in my brother’s truck.Main issue is the system would crash when I put in the cabin camera. I’m not sure if it’s because my car was not strong enough for it or what. But it could not handle all three cameras, so I just kept the front and rear ones in.I had no issues with its memory and it suited my needs. It is very easy to use.

I bought this dash cam because it has all 3 cameras so I can record in front and behind myself and also in the cabin. Too many people are out here driving crazy to not protect yourself with video recording in case of an accident. I liked having it so much I bought one for my dad too!It works really well, video and sound are clear and you can disable the sound if you don't want to record that. It even auto locks recordings of the camera experiences too much force, like if you got in an accident (or in my experience, accidentally hitting a pot hole) and I believe the sensitivity on that can also be adjusted.It is easy to set up, the adhesive pad holds really well, the hardest part is picking a spot where you have good video coverage without blocking your view while driving (I suggest turning it on to help decide placement). They even give you a tool to help run all the wires under the edge of the trim/headliner in your vehicle.I only have 2 complaints:1st, every now and then it tells me to reformat my SD card. I thought it was supposed to record over the old footage when the card got full? Luckily I haven't needed to keep any of my footage yet (there have been a few close calls) so reformatting isn't a big deal but that will delete all of the recordings on your SD card so make sure you back it up first if you want to keep anything.2nd, the adhesive pad is maybe too good at its job. When I bought this camera I owned my car but a year later I sold my car and now do 1 year leases so every year I have to move the camera into a new car and this year the mounting bracket got damaged and doesn't hold the camera very well anymore.Now, when I reordered this dash cam for my dad, his came with a cling film you put on your window and then you stick the adhesive to that (mine did not but I order his quite a while after getting mine so I think they just updated the package), I'm not sure if that will make it easier to move between cars but I hope so.I would absolutely buy this again, it is well worth the money and would pay for itself several times over if you got in an accident and needed to prove it wasn't your fault.
