As you will realize or find out, there are many issues with
Reolinks, especially
nightime performance. Do a search here on that camera. You will get ghost and blur of moving objects. With a Hik and Dahua and setting it up correctly, you will get much cleaner images of motion.
If you set up the Hik or Dahua equivalent to trigger for a person, then yes the timeline will show those triggers. If you go BI, you don't need to open any ports.
Do not be lured in thinking this camera can capture plates LOL. It would have to be perfect ideal situation like a car in a driveway heading towards the camera within 10 feet or so for a camera with a 2.8mm focal length. Capturing plates is all about shutter speed, focal length and distance.
Regarding a camera for plates (
LPR) - keep in mind that this is a
camera dedicated to plates and not an overview camera also. It is as much an art as it is a science.
You will need two cameras. For LPR we need to OPTICALLY zoom in tight to make the plate as large as possible. For most of us, all you see is the not much more than a vehicle in the entire frame. Now maybe in the right location during the day it might be able to see some other things, but not at night.
At night, we have to run a very fast shutter speed (1/2,000) and in B/W with IR and the image will be black. All you will see are head/tail lights and the plate. Some people can get away with color if they have enough street lights, but most of us cannot. Here is a representative sample of plates I get at night of vehicles traveling about 45MPH at 175 feet from my 2MP 5241-Z12E camera (that is all that is needed for plates):
