Some important points to keep in mind while making bandwidth & storage provisions:

• “Hours of Motion” will alter storage (in this calculator).
• The motion-based recording will reduce the storage and bandwidth
• Gigabit Ethernet provides us with maximum useable bandwidth of 500 Mbit/s
• 100 Mbit Fast Ethernet provides us with maximum useable bandwidth of 55-60 Mbit/s
• 10 Mbit Ethernet provides us with maximum useable bandwidth of 6-7 Mbit/s
• WIFI 802.11g 54 Mbit provides us with maximum useable bandwidth of 12-25 Mbit/s
