In general at night it is absolutely unnecessary to use two A329 for that comparison because every Starvis2-Dashcam with HDR disabled will have similar results.
Using the same model will only be necessary if you compare the capability with HDR ON vs. HDR OFF at daytime in situations that require good motion blur capability.
There are some interesting differences always depending on the focus the developer choose firmware-wise.
I can help out with that. Oncoming traffic 50kph EU-License-Plates.
