How long does a 128GB SD card last in a security camera?
A 128GB SD card can last for several days or even weeks in a security camera, depending on various factors such as the camera’s resolution, frame rate, and compression quality. Generally, a 128GB SD card can store around 10-20 days of footage from a standard definition camera, 5-10 days from a high-definition camera, and 2-5 days from an ultra-high definition camera.
However, these estimates are approximate and can vary significantly depending on the camera’s settings and usage. For example, if the camera is set to record continuously, the SD card will fill up faster than if it is set to record only when motion is detected. Similarly, if the camera is installed in a high-traffic area, the SD card will fill up faster than if it is installed in a low-traffic area.
What factors affect the storage capacity of an SD card in a security camera?
Several factors can affect the storage capacity of an SD card in a security camera, including the camera’s resolution, frame rate, and compression quality. Higher resolution cameras, such as 4K or 5MP cameras, require more storage space than lower resolution cameras, such as 720p or VGA cameras. Similarly, cameras with higher frame rates, such as 30fps or 60fps, require more storage space than cameras with lower frame rates, such as 15fps or 20fps.
Additionally, the compression quality of the camera’s video feed can also impact the storage capacity of the SD card. Cameras with higher compression ratios, such as H.265 or H.264, can store more footage on an SD card than cameras with lower compression ratios, such as MJPEG.
