At IP66 rate, the cameras are all weatherproof and protected from water and dust ingestion, and hence, totally safe for outdoor use all year round. The Annke security camera system supports night vision and guarantees a crisp, high quality image on a display regardless the time of a day.

All videos are stored on a built in 1TB HDD that offers the capacity enough for about 7 days of continuous shooting. If 1TB isn't enough for your needs and you expect to use the system longer than that, you can expand the HDD up to 6 TB. In all, the Annke Professional Surveillance Security Camera system is a well designed product that can provide a high level protection as well as some other great features that will be of great use in everyday life.
