Off course this was just test. This far i like the amount of ir light these units put out compared with the ir on the hikvision turret i have in this garden.
Ir unit was like 60 cm below the camera, which stood in 1 floor up from ground level in open door (french balcony) camera was like 5 meter high here and i intend to install camera much lower, perhaps 230 cm to get better facial.
These ir units will have to be insalled also, my first thought is at the eve at 550 cm height, but that will cause short shadows, and not much face detail when subject were caps etc. They would cover my front garden and street nice at that height, as it is only 3 meter garden, 1 meter walk pathway, and 2 meter car park and than 4 meter road. So totally 10 meters maximal and they do 16 meter according to specs, and that will be true seeing the test above i did.
Since i intend to use a dahua mount from the pfb20x series everywhere, i just have one installed under the eve with a conduit for 2 ethernet cables, so i can either mount 2 of these ir units, or even a extra camera.
Could install a 2nd mount just above the windows atabout the same height as the cameras, but that will not look as nice as the heigh install.
