I'm planning to set up a video surveillance system in our house. The model for the cameras is Hikvision 4MP Camera. I want to record continuously for 30 days at 4MP. How much storage does this setup need?

You will need around 953 GB in order to store 720 hour, @20FPS with a resolution of 2688x1520 encoded with H.264

  • BluRay H.264 (1080p25 = 56 Mbps) 953 GB
  • BluRay H.264 (1080p25 = 56 Mbps) 88.3 Mbps = 11 MB/s

Source: Video filesize calculator

Camera Specifications:

  • Frame Rate: 20 fps (2688 × 1520), 30 fps (1920 × 1080, 1280 × 720)
  • Video Compression: H.264/MJPEG/H.264+
  • Video bit rate: 32Kbps~16Mbps

    The only problem with this estimation is that it is indicating a video bit rate that far exceeds the camera specifications. So you are likely going to need far less then 953 GB, but the calculator I used, is limited in it's calculations. The calculations assume you are recording at 2688x1520 at 25 fps, but you are actually recording at at 20 fps, will make a considerable difference in the overall size. The calculations also assume you are recording at that resolution. Since you didn't provide specifics I made an educated assumption. – Ramhound Sep 27 '17 at 18:39
