Hi - I am in the works of starting a home camera installation where I will use a contractor to run Cat 6 cables. I bought Lorex YN843A82-8AB6-E from Costco and it comes with 6 cameras. The NVR allows 8 cameras and today i did a quick power/video test before installation but then ran into a lot...
4K on a 1/2.8" sensor is nt a good combination at all. 4K needs a 1/1.2" sensor to be effective at night. All those cameras are probably 2.8mm which is another problem. A wide angle lens looks nice, I can see the whole yard/neighborhood with one camera, but you can't identify anyone positively unless they're within 10 feet of the camera.
I started with a Lorex system. After not being able to ID a guy at night, 10 feet from my camera, I started upgrading cameras with Dahua from Andy. Then upgraded the recorder (16-channel Dahua from Andy). I only have 2 Lorex cams left. They will be replaced the next sale Andy has (coming soon!) See my Signature file. Buy once and save money! PS: I never thought I would need more than 8 cams
