Wi-Fi NVR recorders

Wi-Fi

— in recorders, the built-in Wi-Fi module is most commonly used for two purposes: working with IP cameras that support such connectivity, and connecting the recorder itself to a local network (or even the Internet) via a wireless router/access point. And in models with a mobile application (see above), Wi-Fi can also be used for direct communication with the controlling gadget. In any case, this connection allows you to avoid the hassle of dealing with wires and connectors. The downside of this feature might be a slight price increase compared to analogs without Wi-Fi, but this aspect often remains nearly negligible against the overall cost of the recorders themselves.
The specifications may also specify the particular supported connection standard — Wi-Fi 4 (802.11n), Wi-Fi 5 (802.11ac), Wi-Fi 6 (802.11ax). In this case, the differences between them are usually not critical: modern Wi-Fi modules generally support several standards at once, so compatibility issues do not arise, and the connection speed is usually more than sufficient for its intended use.
