Do you guys know how many hours of recording do we get with the S-CAM using a 128 Gb Micro SD Card?

Haven’t verified by myself, but to alculate how long you can store a video stream on a 128GB TF card, you need to consider the following factors:

  1. Video Quality: The resolution (e.g., 720p, 1080p, 4K), frame rate (frames per second), and video compression method will all affect the file size.
    –Cam Slim is 720P as far as I can remember.

  2. Video Encoding: Different video encoding formats (such as H.264, H.265) will impact the compression rate and thus the file size.
    ----H.264

  3. Average Bitrate: If you know the average bitrate of the video (in bits per second), you can use it to estimate the file size.
    —This is shown on the live stream window.

  4. Available Space on TF Card: Ensure that there is sufficient available space on your TF card to store the desired duration of video.

Assuming you know the video’s resolution, frame rate, and average bitrate, you can use the following steps to estimate the storage duration:

  1. Convert the average bitrate to bytes per second (if it’s in bits per second).
  2. Use the following formula to calculate the data amount per hour: Data Amount (bytes per hour) = Average Bitrate (bytes per second) × 3600 seconds (1 hour in seconds).
  3. Divide the data amount per hour by 1024 to get the data amount in megabytes (MB).
  4. Divide the available space on the TF card by the data amount per hour (in MB) to estimate how many hours of video can be stored.

Please note that this is an estimate, and the actual storage duration may vary due to various factors including filesystem overhead, TF card performance, etc. If you’re unsure how to calculate or need a more accurate estimate, the best approach is to conduct real-world testing by storing a known length of video on the TF card and adjusting based on the actual results.
