"A network with large bandwidth is capable of supporting devices with higher bitrates, allowing for higher resolution, frame rates, or more cameras on the network without causing congestion."

— Axis Communications Academy, Network Video Fundamentals, 2022

"The greater the available bandwidth, the more data (higher bitrate) can be transmitted without causing network issues."

When recording a night scene with IR, using a day-and-night camera without an IR-corrected lens can cause the focus to shift. This happens because IR light and visible light have different wavelengths and refract differently through the lens. An IR-corrected lens is designed to handle both types of light without causing a focus shift, ensuring sharp images in both day and night conditions. References: Axis Communications product guides on day-and-night cameras and IR-corrected lenses.

"8 Mbps × 3600 s × 24 h × 30 days = 2,592,000 Mb

2,592,000 Mb ÷ 8 = 324,000 MB

324,000 MB ÷ 1024 = 316.41 GB

316.41 GB × 8 cameras = 2,531.28 GB (approx. 2.6 TB for 1 camera for 30 days)."

"8 Mbps continuous for 30 days ≈ 2.6 TB per camera."

A multidirectional camera is equipped with multiple sensors that can be independently adjusted to cover different areas. This flexibility allows for optimal usage of the camera by positioning each sensor to capture specific scenes or angles. These sensors are typically fixed in place once set up, but their initial placement can be adjusted to ensure comprehensive coverage. Axis documents specify that multidirectional cameras are designed for customizable installation to meet varying surveillance needs.

The most effective way to improve the image quality in the provided scene is to add lighting. The image appears to be very dark and grainy, which is a typical result of low light conditions. Adding additional lighting will significantly enhance the camera’s ability to capture clearer and more detailed images. This solution is supported by Axis Communications' documentation on optimizing image quality, which highlights the importance of adequate lighting in achieving optimal camera performance.

"The Axis lens calculator helps users determine the pixel density at various distances, helping to ensure coverage meets surveillance requirements (such as detection, recognition, and identification)."

"Pixel density calculations are essential for planning surveillance installations and the lens calculator provides this information based on camera and lens parameters."

"Bandwidth is defined as the maximum rate of data transfer for a given network path, typically measured in bits per second (bps)."

— Axis Communications Academy, Network Video Fundamentals, 2022

"Bandwidth refers to the network’s capacity to carry data, not the amount of data produced or stored."

The corridor format is particularly useful for scenes such as the one depicted because it optimizes the camera's field of view for narrow, vertical areas. Traditional horizontal formats waste much of the frame on walls or empty spaces when monitoring hallways, staircases, or aisles. By rotating the camera 90 degrees and using the corridor format, you maximize the vertical field of view, allowing for better coverage and more effective surveillance in such environments. Axis Communications documents and product guides frequently highlight this advantage for corridor format applications.

“Thermal radiation does not pass through standard glass lenses, as glass is opaque to the long-wavelength infrared radiation detected by thermal sensors. Special materials such as germanium are used for thermal camera lenses because they allow infrared radiation to pass through.”

— Axis Communications Academy, Thermal Imaging, 2022

“Conventional glass lenses are not suitable for thermal imaging cameras because they block the wavelengths of infrared energy that thermal sensors use. Therefore, thermal lenses are made from materials like germanium.”

An explosion-protected camera is specifically designed to contain any internal explosion within its housing. This type of camera is built to operate in hazardous environments where flammable gases or dust may be present. The robust housing prevents the internal explosion from igniting the surrou

nding atmosphere, thereby ensuring safety. Axis Communications offers explosion-protected cameras that adhere to stringent safety standards to prevent ignition and ensure reliable operation in dangerous conditions, as detailed in their product specifications.
