Which video conferencing equipment to choose?

Question

Video broadcast

Hello everyone, the boss asked a question, to choose videoconferencing equipment but cheap.
Previously, they used the camera from the imac monoblock and now this is not enough.
In fact, there is a room with a large table, there is Internet, and we mainly use free applications via PC, such as Skype for example.
For security, here is the second question. working moments are discussed therefore it is not critical.
We also have a PBX station for SIP, but as I understand it, we are more inclined to buy a good camera thread so that we can shoot with a wide angle and good sound.
The store offered the following iron
camera without microphone https://technopoint.ru/product/f2e580d271b93330/ve...
microphone https://technopoint.ru/product/34d3173da4c13330/mi...
Just wondering if they want a cheap video conference, then here is the link above is the best option or is there something much better and cheaper, or is it the most optimal.
And I guarantee you that a camera for 50 pieces will tell me it's expensive!
But you need a camera with approximately the same angle. all of them at the table will not be visible if the camera has less capture.
And the second question is what software is better to use for videoconferencing and also so that it is not expensive?
In a conference, there are usually 2, maybe sometimes 3 connections. And this is about once a week for an hour.

Answer 1

If it's cheap -
take any webcam with a good viewing angle and quality from 2 MP. Mount it on a monitor (in your case, apparently a telly on the wall)) I would not give more than 3-5k for it.

I would take out the microphone separately in the center of the table, wired, wireless - you decide.
Continue calling on Skype as usual.
Software - there is free software for Linux, for organizing your own server.
As an example, what I tested for my needs.
Apache OpenMeetings
