I am not knowledgeable about
UNIVIEW products. There is little info on the forum on
UNIVIEW product reviews. I do not know the specifics of your application. I would go with the turret camera over the dome camera. The dome camera collects dirt and reflects the IR. Both cameras are using a 2.8mm lens, this will give you a good overview, but may not provide the detail needed to identify the bad guy. Both of the cameras are 2mp cameras with 2.8mm lens. There is no information about the CMOS sensor size. This information is critical if you need low light night coverage.
Not knowing the application, I would start with one good variable focus camera and test each camera location and verify the lens needed for the correct coverage. Test the coverage at night with a "Bad Guy" wearing a hoodie, will it identify the bad guy, will it be useful to the cops and stand up in court.
One of the supporting vendors sells
UNIVIEW, I would contact Nelly's Security and see what they recommend for your specific application.
The current go to cameras are the dahua 5442 cameras with 4MP and using a 1/1.8 cmos sensor.
