Direct answer
Local storage provides direct control and can continue recording without internet when cameras, network, recorder, and power remain operational. It can avoid cloud-storage charges, but the recorder must be secured and maintained; theft, fire, hardware failure, or deliberate damage can eliminate footage stored only onsite.
Cloud storage keeps selected footage offsite and makes remote access and sharing convenient. Tradeoffs include internet dependence, subscription cost, upload bandwidth, retention limits, and provider privacy. A hybrid approach can provide local continuous recording plus encrypted cloud storage for important events. Document resolution, frame rate, retention, camera count, event versus continuous recording, export, account security, and authorized users. The FTC's camera-security guidance recommends encrypted remote viewing, unique passwords, updates, and careful account settings.
