In this case, documents are created and stored in BSON files, Binary JSON (JavaScript Object Notation) format, so all JS types of data are supported. That being the case, MongoDB is often applied for Node.js projects. Good answer still, the only thing I would advise is that MongoDB, depending upon index size (etc) has a max limit of collections per DB on it's default ns size (which is recommended to keep to) of about 18K collections and since sharding works well on single collection basis it seems a good idea to promote the use of a single collection for all cameras.
