Cloud storage was convenient to view at any time, but it might require a monthly or annual fee. Local storage usually used an SD card, which was cheaper, but the storage card with the appropriate capacity had to be selected based on the camera's resolution and the required storage time. 4. ** Focus of the lens ** - The focal length of the lens determined the field of view. The wide-angle lens was suitable for large spaces and could shoot more content, while the telephoto lens was suitable for long-distance shooting to see the details. Indoors, 2.8mm or 3.6mm short focal lenses were generally chosen, while outdoors, the lens had to be chosen according to the distance. 5. ** Usage Scenarios (indoor and outdoor)** - An outdoor camera needed to be waterproof and dust-proof, while an indoor camera paid more attention to privacy protection. For example, it could be set up in a shielded area, and it was usually installed in public activity areas such as the living room. 6. ** Power supply method ** - The most common was a 220V power supply, which was stable and reliable. If it was installed in an uninhabited home without electricity, it could choose solar power, but it had to be equipped with suitable solar panels and storage batteries. 7. ** Voice intercom function ** - This function was very practical, such as being used to remotely educate children or appease pets. Even if they were not at home, they could still communicate with their families. ** 3. Brand recommendations (applicable to local surveillance cameras)** Some big brands such as Hikvision, Huawei, Dahua, etc. were good choices.
