Lot of options here but there are a lot of questions in order to recommend a system.
What are we dealing with inside? 8' ceilings or 15'+ ceilings?
What are you trying to accomplish inside? Are you dealing with a flea market type setup, a store with a lot of aisles, etc?
- Watching over the entire area just to see business flow and general views?
- Wanting to ID every face that comes in and out?
- Watch POS/Cash Registers and the transactions that occure?
What are you trying to accomplish outside?
- Just ID make and Model of car?
- Read License plates of every car as they enter/exit?
- Just simply see customer traffic walking outside?
Understand saying "All the above" above will require specific cameras and setups to successfully accomplish each of these tasks. These are the questions that also will come into play when trying to decide 2.8mm, 4mm, 6mm, varifocal lens, etc.
These are just some of the general questions you need to consider. HIK has quality products but some of their products do lack when it comes to night vision/IR depending on the location and what you are trying to accomplish.
As for the distance - POE is certified to around 330' and then you need to run another switch - meaning if your camera will be placed 330'+ away from the NVR/Switch it may not work (when it comes to textbook). HOWEVER plenty of people have run cameras 500+' with no issues using quality cable - Ebiquiti TOUGHCable has some great first hand testimony here.
Cameras with Matrix IR's are going to give you much better IR night images instead of domes with IR clusters, however depending on where you are mounting these you might need security domes if they are within reach/accessable by customers. Just assure NO security domes are used outside in the elements as if they get rain or snow on them the water spots will becoming blinding by the IR.
