it has 1TB video storage with overwrite and night video too. You have to have 110V to the camera's but they are wireless to the unit connected to your wi-fi. I can pull it up anytime from the App on my phone. It really helps.
I finally went though the legal wranglings and got the people evicted. But they swiped tens of thousands of dollars of stuff. I've got some of their property they could not come back and get and I have no intention of letting go. We are now in "damages" of the final legal struggle and since we have such large claims I think they will settle for where we are. That suits me. I need to get a forged title back in my name on a 2006 2500 GMC Duramax Super Crew 4x4. I hope to sell it for a handsome price and recoup some. In all I'm out a very conservative $6k in legal fees alone and 4 years of worrisome strife.
