Session Initiation Protocol (SIP) is used to set up peer-to-remote calls, peer-to-peer calls, and SIP trunk calls.
SIP is a signaling protocol widely used for initiating, maintaining, and terminating real-time communication sessions, including voice, video, and messaging applications. It facilitates communication between endpoints, whether they are directly connected or through a SIP trunk. Axis Communications' technical documentation on SIP and VoIP solutions confirms these uses.

Axis recommends shielded cables for outdoor installations primarily to ensure surge protection. Shielded cables help to protect the system against electrical surges and electromagnetic interference, which can cause damage to the cameras and other connected devices. By using shielded cables, the integrity and reliability of the surveillance system are maintained, even in environments prone to electrical disturbances. [Reference:

Using bidirectional predictive interframe in H.264, also known as B-frames, will increase the latency in the system. B-frames depend on both previous and future frames (I-frames and P-frames) for encoding, which requires more processing time and thus increases the latency. This trade-off allows for more efficient compression and smaller file sizes but at the cost of increased delay.

"A shorter exposure time, such as 1/500 second, is recommended for capturing fast-moving objects in order to minimize motion blur, especially in well-lit conditions where there is sufficient light for proper exposure."

"To freeze fast-moving subjects, use fast shutter speeds such as 1/500s or shorter."
