For optimal video quality, what resolution should CCTV cameras ideally support?

High definition resolution is considered optimal for CCTV cameras because it provides a clearer and more detailed image compared to other resolution standards. This increased clarity is crucial for identifying subjects, reading license plates, and capturing important details in surveillance footage.

High definition typically refers to resolutions like 720p (1280x720) and 1080p (1920x1080), which deliver significantly more pixels than standard definition or enhanced definition options. These higher pixel counts enable the camera to capture sharper images and provide a better overall viewing experience. Additionally, high definition footage allows for better digital zoom capabilities without losing picture quality, making it easier for security personnel to analyze the footage more effectively.

Options such as standard definition, enhanced definition, and low definition lack the high level of detail and clarity that high definition offers, making them less suitable for comprehensive surveillance needs. Standard definition typically refers to 480p or lower, while enhanced definition may only provide slightly better quality but still falls short of what high definition can achieve. Low definition presents the least clarity and would likely fail to capture necessary details for identification and analysis in security contexts. Thus, high definition is the most recommended resolution for effective CCTV surveillance.
