Time Lapse over 4G is the next generation of building site time lapse cameras. The 4TH Generation High Speed Cellular Network is an advanced solution. This is used to record projects through remote image archiving. Time Lapse over the 4G Network also allows you to view the building site remotely. Some people do ask for 4G, as they like the best and they like to future proof. However, a 3G set up is sufficient. The network camera is not constantly active, therefore capturing images every 10 or 20 minutes will be fine over 3G.
