Start by identifying whether you need local edge storage, cloud storage, or a hybrid approach, and then match that to retention needs and the number of cameras. Consider deployment type (home, small office or business), your desired retention window, network bandwidth, and compatibility with your preferred brands such as Uniview, Dahua, or Hikvision. Look for bundles or kits that clearly state storage capacity (for example 1 TB or 2 TB) and whether storage is built into the cameras or provided by an NVR/digital video recorder. Check how the solution handles codecs and compression to maximize efficiency. Finally, assess ongoing costs and scalability so you can expand later if your surveillance footprint grows.
