I dont know how much size of DVR would be required. This system will record 24×7 regularly and DVR should be capable of storing at least 30 days of recording. Please advice the size and calculation technique. And, what is the best/ recommended image resolution since I am keeping 30FPS, what is the recommended bit rate? NOTE : I dont have cameras yet with me as I am still in the designing stage and would highly appreciate your assistance.
