Obstructions: Physical obstructions, such as walls, doors, and other obstacles, can attenuate sound and reduce the effective audio range of the camera. Sound waves can be absorbed, reflected, or diffracted by obstacles, affecting the clarity and range of captured audio.

Do CCTV cameras record all the time?

While some cameras record 24/7, others may only record at scheduled times. Some cameras only record when alerted. When motion is detected, a camera system may start recording.

CCTV systems may record 24/7. This mode is used in high-security places, important infrastructure, and public spaces that need ongoing monitoring. These cameras record continuously, catching every moment in their range of vision. Continuous recording ensures that no event goes undocumented, which can be crucial for investigations or legal purposes.

To conserve storage space and minimize the amount of footage to review, many modern CCTV systems offer motion-activated recording. In this mode, cameras only start recording when they detect movement within their defined detection zones. This approach is effective in capturing events of interest while reducing the volume of irrelevant footage, such as empty corridors or static scenes.

CCTV cameras can record on schedule. Recording may be activated at peak hours or when security is absent. This approach can help manage storage capacity and focus recording efforts on times when incidents are more likely to occur.

How do I check if CCTV is recording?

  • Camera Light. First, check the light on the camera itself.
