Here is a 8 channel security camera system that lets you use bullet and dome weatherproof CCTV cameras to keep an eye on your place. The ZOSI 8CH Security Camera System comes with the ZOSI View app, so you can see all the cameras in one place.
The system has motion detection, so you get notified when unexpected movement is detected. Simply bring your hard drive, and you are set. You can access your cameras over WiFi and 4G.
