Used indoors to determine who is coming into the warehouse and to get an overview. Great hardware, compact, good WiFi sensitivity. Excellent image quality and very good IR illumination. Color images require a certain basic brightness of the environment. Motion detection has been very useful so far and works as desired. Push notification works well. The software (app) is relatively simple, but the basic functions are there. I still have to deal with the storage, the memory card and the retrieval of the alarm recordings. At the moment it is almost only used in live operation. The translation of the menu navigation into German was probably automated, the purpose of the function is clear. The intercom system is acceptable. Unfortunately, it can only be operated via smartphone/tablet. PC software would be desirable for monitoring in the office (using an Android emulator, e.g. NOX, is rubbish). I am very happy with the device so far. Addendum: Charging with the small solar panel works better than expected. A sunny day in between (brightness alone is not enough, the sun has to shine) recharges the battery. Depending on the location, the panel can be wiped clean of traffic jams, or the rain can wash it away by itself.
