Best dash cam for Chevy Tahoe

[The Grey Beast]

Looking to install a few after market items. One of which is a dash cam for from and rear of the vehicle. I drive a 2011 Chevy Tahoe LTZ. My question is how is the install with wires properly. I watched the video's and have the tools. Is it difficult or just time consuming? What camera system do you recommend? I'm trying to check if there are wireless cameras but that would incur constant taking the unit off and charging.

Thank you for reading my rant.
