When your camera isn’t sending all or almost all the photos it takes, that usually indicates a problem with signal strength. How do you check to be sure the camera is sending photos consistently?
This example shows a video-enabled camera that was set to photo-only (1 photo per trigger) and photo+video at different times. When this camera was deployed, it replaced a camera that had been sending a good number of photos each day, especially at night. The first night this camera was deployed, it hardly sent any photos that it took, which was confirmed by looking at the photos on the portal.
The photos with information marked in yellow were transmitted by the camera (a V4Gb) with the standard “candy-bar” antenna. It was set to photo only through photo 12; photos 3 through 10 were not transmitted. Photo 12 catches when the camera was checked to be sure the antenna was secure and the setting was changed to photo+video. The camera transmitted 12, 26, 40, and 42 but did not send 28, 30, 32, 34, 36, or 38.
Before photo 1 on 10/29, 2017, the camera was reset to defaults and a directional antenna replaced the stock antenna. Photo 3 is the beginning of photo+video and the photo numbers following that show that the camera sent every photo.
This is a camera set photo mode, 1 picture. It is in a one-bar signal area, so an occasional missed photo is not cause for concern. As you can see from the photo numbers, the camera took but did not send photo 44.

If you are getting photos via email, the file names of your photos should be numbered consecutively if the camera is taking one photo per trigger. If you are using 2- or 3-shot burst mode, non-video-enabled cameras will send the last photo taken, so the numbers should count up by either 2 or 3. On video-enabled cameras, which can sent all photos taken, the numbers should be consecutive.
