I have spent a good few hours reading posts on the forum and looking at video capture quality.
I have also taken to heart the wisdom of having spotting cameras coupled with PTZs.
Considering multiple 49225s plus maybe a 45x 2mp big boy.
Cameras that appeal to me as spotters are:
IPC-Color4K-T180 2×4MP 4K Full-Color Warm lights Dual 1/1.8" CMOS Dual-Lens Splicing Network Camera
I have just purchased this from Andy, together with an EPTZ-capable NVR.
Other cameras I am considering are:
TPC-BF1241-S2 ( A thermal camera with a 10mm lens 4MP 1/2.8 sensor, but an f1.0 optical lens, it reports to have 417m thermal human detection, though).
Another camera that has impressed me with its performance is the dual lens infrared + normal lens camera.
IPC-HDW5449H-ASE-D2
6mm with 1/1.8" + 1/1.8" CMOS could also have its place, but I can't find much about this camera.
I have read the detailed review of the 3.6mm version with the 1/2.7 older sensor. Thanks,
@Wildcat_1. I like this cam because I can see how hard it is to identify using IR, but once it flips to colour, even for a moment to identify, then the rest of the scene can be followed in IR.
I know a thermal camera will take two NVR channels, but it evens out when combined with the other cameras that use two sensors on a single channel.
The long-range IR-capable varifocals are also on the table, but I haven't thoroughly researched them yet either.
I have a rural property with a maximum of 400m (in darkness) from the dwelling to cover (and about 2km of poorly fenced vulnerable borders).
Livestock, solar panels and firearms are the targets. The closest neighbours are 2km away. The idea is to sense humans just outside the perimeter at a long-range, switch remote lights (either white or IR, undecided), and use long-range PTZ to identify trespassers.
I am considering covert cameras and external IR floodlights because intruders will wear masks if the cameras are obvious. The cameras and lights themselves will be vulnerable if they are far from the dwelling. I will be using underground optic fibre due to lightning.
So looking for suggestions on single or double-port media converters with POE+.
Covert LPR is an option as there is a rural road entry on one border, as the place will be cased out beforehand.
I will be piecing this system together over the next 18 months.
Anybody is welcome to chip in with any suggestions.
