Question

CCTV

The task was to put the camera in the room, got into the Internet, and there are a lot of cameras, but how to choose is not at all clear, for example, cameras of 2mp, and on a phone with such mp I would not have seen anything at all, can someone tell me?
You need a camera:
to connect to a PC - USB / IP
FullHD
with high definition
with night illumination
, viewing angle 90-180
all kinds of recordings to the cloud, microphones, nannies, etc. are NOT needed and will in fact only interfere.

Answer 1

I didn’t see anything in your question about the recording storage time, I suspect that it will be necessary and in order to kill two birds with one stone and not buy additional equipment such as a DVR, I can advise the Hiwatch DS-I214W camera https://hi.watch/product/ds_i214w .
A memory card is inserted into it and you can store everything locally, remote access is quite simply configured on your phone or on a PC, Wi-fi communication is also possible, you only need to connect the power cable. For a larger viewing angle, choose a model with a 2.8mm lens, which will correspond to almost 105 degrees.
