Recording storage calculator

[jesd03]

Hi,

Is there a calculator flying about as to how much storage I would require or how much of a recording I can retain before being over written?

I will be running 6 cameras (5 up already) on 1080p and currently set on 25FPS. I have ordered a 4TB hard drive which will be delivered in the next few days.

Anyone know whether the NVR has a feature which tells how many days the data will be retained before being over written?

I am looking to record 24/7.

Thanks

Each manufacturer has their own calculator and requirements for HDD, so it's not completely universal. How ever a good estimate can be gotten from pretty much any calculator, first result from google for "storage calculator cctv" was http://www.stardot.com/bandwidth-and-storage-calculator

According to this calculator, you would need ~4.5TB for a week if you record 24/7 1080P 25fps at highest quality.

Storage is simply a calculation of the bitrate - nothing else..if you increase fps and resolution you will need a higher bitrate to get a good image...
...if its a variable bit rate then you cannot come to a precise conclusion..

You will see that when you change fps, it adjust the bitrate, but if you keep the bitrate the same the storage requirement will be the same.

thanks for the info guys, I might be recording at 15fps due to storage requirements.
