Over the past few weeks I've been learning a lot about camera options and equipment. Once I decide on going with either an NVR or PC with software, i'm planning on a 25x zoom turret camera to view various bird feeders and houses on my property. (And to help with an overall security program. )
Thinking I would always use it somewhere, I thought I would pick up a sub $200 vari-focal cam and see what kind of results I could get from it.
The camera I picked up from Andy was a DH-IPC-HFW2831T-ZAS .
It's a 3.7~11mm motorized lens My initial thought was to mount it at about 8 feet away. Being a varifocal, I was hoping when zoomed in I could focus on a relatively small fov. (2 to 3 feet). Not with this camera. When zoomed in all the way, I would have to be about 3 feet away from the subject.
I'm looking for a camera that has a field of view of approximately 2-3 feet at a distance of about 16 feet. Is there an easy way to calculate this? I've played around with some online fov calculators and I've not been able to grasp the concept of lens size/type vs. fov.
Any advice or suggestion for an appropriate camera would be much appreciated!
