As I said before, the Model of IP camera is CAMHI pcs112. Also, as I said before, my Decos operate in access point mode and dhcp server is runnung on the main Mikrotik router. In that configuration I can't reserve anything on Deco, but I can do this on the main Mikrotik router and in this case everything operates and indicates correctly. The question was why, if use static ip for the camera, I see it in inactive devices although  the camera operates correctly itself. I think the problem somehow is connected with a new update for before it everything was correct with the same settings.

By the way, after the new update I have access to the Deco via web inteface :) And I see the log section. But there is  no any interesting in logs for this camera

After today's updating deco app to the new version, it seems the problem's been resolved. At least it's shown correctly within active device group with dinamic IP as well as with the static IP

@RedRoger I have almost the same problem. I have a Deco E4 (set of 3). I have a Raspberry Pi that has been allocated a Static IP address. My deco is running in Access Point Mode. My PI device is always on and connected but in the Deco app it is shown as Offline.

I also have another machine, a laptop, which has a Static IP allocated to it. That machine too is marked offline. When troubleshooting this issue, I deleted the record in the Deco app for the laptop and now it is nowhere in the list. I can see no way to list it back in the app.

Here's ping result showing both the machine being accessible, while being reported offline on Deco

@RickyGoldsmith yap, my problem is also exist so far... For the short time, once after deco app last update, it was shown correctly, but after the short time camera again moved to the offline group. It works properly but is shown offline ...

@RedRoger Here's an interesting bit from today. My lenovo laptop is now automatically named by Deco as Hon Hai Precision Ind and is marked as an offline device. I was able to confirm that it is my lenovo laptop by verifying the wifi mac address of the laptop. So there's something wrong with how Deco tries to discover a client device.
