I think i have finally got mine set decently. It still has a little trouble reading plates from time to time, but i try to make a habit of calling out plates to the camera if something happens. I think once i get it aimed more correctly plates will be more viable sometimes they are readable and sometimes not while playing the raw file in VLC.
Compared to my DVR-027 it is light years ahead. It sees really well in the dark. The street i park on has one streetlight on each block and the camera can see great with the one light in view it's a little grainy, but it's not that bad and we are talking 2-3 am with one streetlight. The WDR seems to really make a bit of difference during night time driving with headlights coming at you. I have left it in my car with the windows up for about 4-5 days and heat is not an issue it seems built really well and sturdy.
So far for me the TF2 Plus Premium has been really great and defiantly worth the money.
Pluses for me include
Really good Image Quality during the day
Rather good Image Quality at night under one street light.
A mute button
Being able to rotate the image and stick the camera on the top of a glass roof suction side down
The Vico Scheduler allowing me to set different EV Values and WDR setting for day and night to get the best image i can depending on the time.
The Event button so when something happens push a button and it is protected. I can go a few days without worrying about loosing interesting footage
The plate stamping is a nice feature, but needs more space
It has a big screen and i am screen on my camera kind of person. It even seems to have aiming guides with i need to pay more attestation to.
Some small negatives include.
You can not set clip length. I happen to like it's 5 min clip setting, but some people may not and i can not seem to change it.
When you press the mute button it only seems to stay muted until a new clip starts.
Some times i can read a plate of the car in front on me sometimes not, but i think this is more so to do with the way i have it facing in my car.
Some clips i have seen posted look slightly better then my TF2+P raw files, and some seem as good as mine, but i am sure you get that with every camera.
All in all i am currently extremely happy with my TF2. If it is within your budget i would recommend it.
