When the landlord enters my room, can he record it or make a video?

It depends on specific things. If it's your own, that's fine. If it belongs to someone else, it is illegal without approval. If the landlord forcibly, you can call the police, and the police will file an investigation.

During the lease period, the landlord enters the house rented by the tenant without the tenant's consent, causing losses to the tenant, which is illegal intrusion into the house. Illegal intrusion into a house refers to the act of entering a citizen's house against the wishes of the members of the house or without legal basis, or refusing to quit after entering a citizen's house.
