IP based video surveillance gives you endless possibilities for maximum security. IP cameras can be used both as a standalone device, with an NVR recorder or with third-party VMS software such as Milestone (recure that the cameras is ONVIF compatible). The advantage of using an IP camera as a standalone surveillance camera is that you do not need an NVR (network recorder). However, we always recommend an NVR for your system as this gives you much better management possibilities.
It also makes it much easier if you have to install many cameras to make multiple collection points via PoE switches. Thereby you do not have to install cables to the same place, but instead just install the cables to bases (poe switches) instead.
