Wifi antennas & routers with good penetration across walls

https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2380057.m570.l1313.TR10.TRC4.A0.H0.Xlong+distance+wifi+antenna.TRS2&_nkw=long+distance+wifi+antenna&_sacat=0

I'm looking at some of the above: anyone know if the one with 3km distance has good penetration against 2 layers of walls
(each layer of about 15cm thick)?

I'm placing a wifi router with a camera in my car & from my office which is about 500m away, I want to be able to connect
to the camera to monitor the car (from vandals) from my office PC.  There could be 1 to 2 layers of walls in between.

Feel free to recommend any other products.  Don't need encryption, only good distance/penetration

Thanks very much Robert, the cnet link is good.  I'll close this thread in 2 days if I can't think of any further queries.

Depending on where I park (subject to carpark lots availability), the distance can be just 200m away from where
I sit with 1 wall in between so I thought the 3km booster may stand a chance.  If it doesn't, I'll use it for something
else before considering the costlier ubiquiti

I haven't got the item below: what's the purpose of the USB cable?  For powering the booster or for it to link
wireless router? :

Not sure but i image it would be for power as well as connection for configuration.
