What to do if your camera is not recording correctly to the SD card?

What types of recordings can I make with an SD card?

• Battery-powered cameras:
  These cameras can only store snapshots on the SD card. These are short clips recorded when motion is detected.
• Adapter-powered cameras:
  These cameras offer the ability to capture both snapshots and continuous recordings. This means you can store longer videos, depending on available storage space.

If the SD card is installed correctly and, based on the information above, you have selected the correct recording setting, but your camera still experiences problems recording to the SD card, such as missing recordings, recordings that are too short or error messages during playback, in most cases the problem lies with the SD card.

The following factors may play a role:

1. Damaged SD card:
   Check if the SD card has physical damage or may be defective.
2. No genuine SD card:
   You may have purchased a counterfeit SD card. These cards often have lower quality, incorrect storage capacity or do not function properly.

How can I check if my SD card is working correctly?
You can test an SD card using specialized software, such as H2testw. This free tool checks both the speed and capacity of your SD card.

• Where can I download H2testw?
  Go to the official website: https://h2testw.org/.
• How it works?
  1. Download and install H2testw on your computer.

Counterfeit SD cards are often sold through unreliable web shops, Ali-Express or other similar platforms.
These cards:

• Are less reliable and can break down quickly.

How can I make sure I am using an appropriate SD card?

2. Avoid buying SD cards through unreliable online shops. Choose official stores or reliable online sellers.
3. Make sure the card meets the recommended specifications for your Calex camera or video doorbell.
4. Buy an SD card with at least V30 or U3 speed class.

• Check if your Calex device supports the storage capacity of your SD card.
