Oh really? I had a look and couldn’t see any thought it was because this is a new camera. Let me have another look!Yes, you can pop it open and manually adjust. Threads here talking about it.
The lenses are a screw mount and pre focused at the factory. The Colorvu cameras use a wide aperture lens (which lets in more light), but the down side to that is the depth of focus (the distance range in focus) will be reduced. The specs do mentioned the minimum focus distances, for your 2.8mm it'san’t believe there isn’t an external focus toggle if this is the case
Depth of Field 10 ft 2 in (3.1 m) to ∞
thank you. I never realised. So it states 3.1m to infinity that I assume is the factory set focus. Is there any spec sheet where I can see the minimum focus point that it can do?i need it in focus by 1m really and am happy to pay the price of further being out of focus.The lenses are a screw mount and pre focused at the factory.

All fixed focus cameras will suffer from this, but the range in focus will vary from camera to camera. You can refocus it to suit your particular needs, but keep in mind adjusting it for closer distances will most likely put distant subjects out of focus.
A varifocal camera will suit you better, but they cost a lot more and last time I checked there weren't any 8MP Colorvu varifocal cameras. The focus on them is electronic, they will auto focus or you can (electronically) manually adjust it to suit.
3.1m is the closest it will focus (as set up by the factory so the focus to infinity is correct.) As mentioned, the only way to change it- so it is focused at 1m- is to pull the camera apart and adjust the screw mounted lens. It's not something I'd recommend doing unless you're familiar with working on electronics. I've done it on older model Hik cameras, but also am an electronics tech. The focus will need to be adjusted with the camera apart and running, that's make it more involved as you need to be sure to not short anything out.I never realised.
