I just returned from a 2 day seminar in Seattle on Mobotix, the best kept secret in the Video Surveillance industry. Aside from the obvious advantage of being engineered AND manufactured in Germany, Mobotix IP camera's are by far the most technologically advanced security alarm surveillance IP camera on the market today.
Equipped with onboard storage (SD Card) as well as a powerful processor with edge processing, these camera's have the widest view and best depth of field I have EVER seen. And I have been in the security alarm industry for.... well let's just say a long time.
