Just admitted my husband into a nursing home. He has Alzheimer’s. I have Parkinson’s. Because of the Covid virus I am not allowed in the building. Does anyone know if such a device exists that would let me see and talk to my husband in the home from my home?
A regular laptop or phone can accomplish what you are seeking, but not on a 24/7 (continuous) basis. Are you familiar with facetime , skype, whatsApp? Your husband has Alzheimer's, so he probably would need assistance with his device in order to see and hear you. Depending on what stage of the Alzheimer's he's in, he may not be able to understand how to make calls to you, or to receive calls from you.
Again, before you put out money for a system, make sure it's okay with his facility for you to have this set-up installed. There may be privacy issues involved (workers and other visitors being recorded and watched might not be okay with the facility).

Some allow cameras.
Most states do not allow recording unless agreed to by both parties. (and this would include staff if the cameras and audio are on.) If you are talking about a video talk many places are doing that so families can visit. Either a phone or tablet that the staff could bring to the room.
