2.4.Restrictions

Access restriction

The camera has access restriction feature that enables to deny access from a specific IP address. If JPEG is requested from the IP address of access restriction, the camera disconnects the TCP connection after API is sent.

Restriction by maximum bitrate of the camera.

The maximum bitrate of the camera is about 20 Mbps.

Number of clients

The maximum number of clients that can get JPEG stream depends on encode settings and requests from client.
