Does the camera see on its own at night or does it need light?
No visible-spectrum camera sees without light: what they do is make better use of the little there is. When the catalogue says it goes down to a very low lux figure, it is usually with the image in black and white, with a very slow shutter and with the gain at maximum, and that means a noisy image in which a moving subject comes out smeared.
The useful question on the visit is not whether it sees at night, but where the light that will be there comes from. If it is the council street lamp, reckon on somebody switching it off or moving it one day. If it is the neighbour's light, on the neighbour leaving. If it is your own light, you have to decide who switches it on and what happens if it blows. That conversation avoids the surprise of the first winter.
The simple way to check before signing is to go to the place at night and take a photo with your phone from where the camera is going to go. It is not a technical measurement, but it shows you straight away whether there is any light or whether the place is black.

See it working.
A written answer is enough to decide whether it interests you. To know whether it works at your site you have to see it on a real scene, with the image as it is and, on top of it, what the system understands from it. That is on the IRIS Neural website, which is the group's product.
