Maximum Network Cable Length
Evolution cameras will perform best with a gigabit Network. We recommend using a gigabit switch plus using a video server or NVR with a gigabit network capabilities. A cat5e cable and above is also recommended.
The theoretical maximum length of network cable (Cat5e or higher) that can be used to connect to our IP cameras is 100m (328ft), however we do highly recommend that installers limit the maximum length to 80m (262ft).
This applies only to connections from switch or hub to your Oncam Grandeye PoE camera product.
