I settled on the 10-watt IR.
I (and I'm sure others) would be very interested in seeing some new screenshots or video after dialing things in manually (presumably with a faster shutter in the 1/60 to 1/100 range, as we are frequently advised to do to avoid motion blur). Even your original on-camera IR illumination (on exactly the same cameras as mine) look vastly superior to my results. I just pulled the trigger on ordering the same "new" series 10W Tendelux as you, but haven't received it yet.
One thing that might be degrading my setup is the way I mounted my cameras up under the eaves, below the gutter line (barely) but only a few inches back from those gutters (single story house, and the FOV is 25-35 feet back, so shallow angles). Obviously they are low enough not to be visibly blocked by the gutters in the FOV, but I might be getting some IR bounceback than is darkening (and possibly "clouding") the scene overall.
Can you add any insights into distances from the camera (or
IR light) out to some of the objects in your FOV in these scenes? It would be helpful to know how far out the building behind the fence is for example.
