IP subnets and VLANs are commonly used network features to prevent unauthorized access to the surveillance network. By segmenting the network using IP subnets, different portions of the network can be isolated, reducing the risk of cross-network attacks. VLANs (Virtual Local Area Networks) further enhance security by creating separate broadcast domains within the same physical network, thereby isolating surveillance devices from other network traffic and improving overall network security and performance.

Before upgrading an installation with analog PTZ cameras using Axis Q-line encoders, it is crucial to check that the PTZ driver is supported. Ensuring compatibility of the PTZ driver with the encoder guarantees that all pan, tilt, and zoom functionalities will work correctly after the upgrade, maintaining the camera's full operational capabilities.

For multicast streaming to be effective, the network infrastructure must support multicast protocols. This involves network switches and routers that can handle multicast traffic, allowing video streams to be efficiently distributed to multiple clients simultaneously. Multicast reduces the load on the network by sending a single stream of data to multiple receivers, making it essential for large-scale surveillance deployments.

True security when using HTTPS on Axis products is implemented after a signed certificate is installed. This certificate ensures that the communication between the camera and the server is encrypted and authenticated, providing a secure channel that prevents unauthorized access and tampering.

A camera lens with a low f-stop value, such as 1.2, has a larger aperture, allowing more light to enter the camera. This improves the camera's performance in low-light conditions by increasing its sensitivity to light, resulting in clearer and more detailed images when lighting is poor.

The IP51 and IP52 ratings indicate that the camera is protected against dust and dripping water. IP51 means the camera is protected against dust ingress to a level that would interfere with the operation and against vertically dripping water. IP52 offers the same dust protection but also protects against dripping water when tilted up to 15 degrees. These ratings make the cameras suitable for indoor use where dust and minor water exposure might occur. Axis Network Video documentation specifies the IP rating system and the levels of protection provided by different ratings.

AXIS Design Tool is used for determining camera coverage and creating a bill of materials. This tool helps system designers and installers to accurately plan camera placements, ensuring optimal coverage of the surveillance area, and to generate a comprehensive list of required components, facilitating project planning and budgeting.

The P-iris (Precise Iris Control) technology in Axis cameras ensures optimal image quality by precisely controlling the iris position. In bright lighting conditions, P-iris prevents the iris from closing too much, which can cause blurring due to diffraction. Instead, it maintains an optimal iris opening to balance depth of field and image sharpness. For more information, consult Axis Communications' technical notes on P-iris technology.
