I need a device to be used in a small conference room, to handle video, microphone and speaker. It will be used for meetings and small trainings where one or two persons will connect remotely to participate. Should be under 1KUSD

I already have a tv used to connect the laptop that is used on those meetings. The duration is normally 1.5 hours, but once in a month we might have a training that lasts 3 hours. The room is quiet, we don't have too much noise, but hearing the participants and handling multiple interactions is crucial
