70mai4G Hardwire Kit UP05, 4G Support, Type-C for Dash Cam A510, X800, A810, 12V-30V to 5V/2.4A, Remote Monitoring, Low Voltage Protection, 24H Parking Mode, Compatible with AT&T SIM Cards only

Installed this with my 70mai X800 dash cam and it's been running smoothly. The 4G connection is stable and gives me access to remote live view and alerts, which adds a lot of peace of mind when I’m parked. Despite what the listing says, it also works with a T-Mobile SIM card—I popped one in, and it connected without any issues.The parking mode works great, and the low voltage protection seems to be doing its job—no battery drain so far. Setup was simple, just make sure to tuck the wiring properly. If you're using a compatible dash cam, this kit really brings out all the features. Definitely worth it.

Worked perfectly with a Tello sim card in Houston, TX. Highly recommended for a 70mai Omni camera

I got this parking monitor with mobile data connection for my Omni 360 camera. It works great for me, it provides parking recording while the car is off. It is easy to install, you can use fuse block adapters and don't even have to get into the wiring. It allows mobile access to the dash cam which is really neat for remote monitoring. The video quality is great and the connection is fast.

I had this installed by someone with the 70MAI powerbank(from their site). The installer installed it slightly wrong and I had to troubleshoot it myself.I tried 3 SIM cards from USMobile / Tello / Boost and I saw it didn't connect. USMobile was never detected in the 4g kit. But Boost and Tello(Tmobile) were blinking green instead of red like the USM sim but it never connects. I found out later on the installer never installed the type C cable to the my A810.So the issue was the installer hardwired my powerbank. Hardwired my 4g kit straight to the car. But connected my A810 to my powerbank.The way it should be is. Hardwire the powerbank to DC. Then connect the 12V output cable with the 4G hardwire kit, then attach the 4g Kit and A810 with the included type C cable to make it work.I use a Tello Sim card with 5gb data only for $10 a month and it is working great.

I've had to edit my review because this company doesn't want to hear the truth that they ship separately the parts versus the camera it's poor quality and there's no customer service support
