The setting of the camera is very intuitive and very easy (hence 2 stars). In contrast, progressive alarm is simply unbearable! The sound rises higher and stronger, I do not know if it's up to the maximum volume but you have to stand up to stop the fear of waking apparatus throughout the building. It is in the machine's system and therefore can not be adjusted or have the choice in the alarm style. I find it intolerable to sell such a product. I had to make it!
