This is a very gerneral question.
Firstly, you need to know what and where you want to monitor.
Typically, for home CCTV and Office CCTV, the camera type should be Indoor CCTV camera with Infrared for Night time ( Black and White Video Footage). If you wnat to monitor a outdoor envinment, you need to get Outdoor CCTV camera. For example, viewing the gate, explose to rain, and etc.
For Warehouse CCTV, the camera type should be Outdoor CCTV with strong Infrared for Night time ( Black and White Video Footage ) because the viewing distance is longer. Otherwise, in total darkness, you hardly see anything. Of course, if you have more budget, you might need a vandalproof Outdoor CCTV camera.
Secondly, you need to know how long the footage you wish to keep.
Typically, we recommend.
4 CCTV Cameras with 1 Terabtyes.
8 CCTV cameras for 2 Terabytes.
16 CCTV cameras for 4 Terabytes.
Of course, if you need longer recording footage, you need to get more harddisk.
We hope we had provide sufficent information for you to select a suitable security CCTV camera solution.
