IPX4 waterproof protection means the electronic device can stand splash of water, for example sudden splash of coffee, dropped into water sink or puddles of water. In rainy days you can use your cameras or drones to take photos and videos.
IPX7 waterproof protection means the electronic device can be dipped into 1 meter deep water for around 1 to 2 minutes. For example, if your phone is dropped into a shower tub, you can pick it up unharmed. If you dropped your smartphone into the swimming pool, you have 2 minutes to get it back before it is totally damaged.
