Complete surveillance rarely rests on one device: the camera sees, the recorder keeps the footage, the doorbell lets you talk to a visitor, the sensor notices an open window. The subcategories follow exactly those roles — IP cameras, DVR/NVR recorders, smart locks, doorbells, security systems and surveillance accessories. Dahua, IMOU, Ajax and Tapo devices differ in whether they run in their own app or as part of a larger system. Start by working out how many points you actually want to cover, and whether footage must survive an internet outage.
