What is the primary advantage of IP-based surveillance systems?
IP-based surveillance systems allow for higher-quality video, remote access, and scalability.
Which technology allows surveillance systems to provide night vision?
Infrared (IR) technology enables surveillance systems to capture clear images even in low-light or dark environments.
What type of cameras are best suited for wide area surveillance?
Pan-tilt-zoom (PTZ) cameras are ideal for wide area surveillance due to their ability to zoom in and move to cover a large area.
Which audio surveillance technology is used to enhance audio clarity in noisy environments?
Directional microphones and noise-canceling technology are often used in noisy environments to enhance audio clarity.
How does motion detection in surveillance systems work?
Motion detection works by analyzing the changes in a camera's field of view and triggering an alert or recording when motion is detected.
What is the primary purpose of video compression in surveillance systems?
Video compression reduces the file size of video footage, allowing for more efficient storage and bandwidth usage.
