VIOFO A329S 4K 60FPS Dash Cam Front and Rear, 4K+2K Dual Dash Camera for Cars, Power Saving Parking Mode, Wi-Fi 6 App Control, Dual STARVIS 2 Sensors, Supports up to 4TB SSD

Anything from Viofo or Rexing. I'm currently using the Viofo A329S 4k with the HK4 Hardwire Kit. I bought a USB-C extension cable and a sata adapter and have it under my driver's seat. You can hide the cabling pretty easily. The MicroSD card is sort of a "decoy" in that it functionally works just fine if the SSD is disconnected but the SSD is the primary storage device. If some cop decides they want to destroy evidence, they'll think they're safe by taking the camera and/or the MicroSD and I'll still have the real footage.
