Sending The Photos And Videos - Libelium Waspmote Technical Manual

6. Sending the photos and videos

Waspmote can take pictures from two states. When Waspmote and the 3G/GPRS are in sleep mode it can wake up and take
a photo or start recording a video in 1,3 or 1,7 seconds according to the configuration of the camera. If the module 3G/GPRS
starts from the OFF state, the time required increases to 11-15 seconds due to the initialization time required. The table below
contains the time required to take a picture or to start recording a video in the different configurations.
