There are analytics features (see below), and also Dewarping Mode, N+M Hot Standby redundancy for fail-over and immediate backup, and Automatic Network Replenishment (ANR) for automatically storing to a camera's SD card if the network gets disconnected and automatically recovering the data afterwards. The NVR also supports an optional Point of Sale (POS) feature, ideal for grocery and retail stores, for monitoring cash transactions.
