Furrion Backup Camera Quality and Performance

For those of you that have the Furrion Backup Camera, is it a clear HD picture in the monitor and is there much lag/delay? I've been reading that some people are reporting up to 3 seconds delay between the time something happens and when it's viewable on the monitor and that there are other systems that the display is clearer and the lag is a lot less. I'm just not sure if it's a big enough deal to buy something else and modify the mounting. Your input is greatly appreciated.
