Can anyone do this bit of maths

Can anyone do this bit of maths? I can't seem to work this out, maybe not enough info. See what you think.

4 cameras running at 25fps each 24/7. How long to fill a 1TB drive. My stab in the dark is about 2wks but I could be wildly out. Just an estimation would do.

35mm or super 8?

depends on quality of frame what are the cameras rated at in Megapixles and file type?

FruitBat, I don' know, I would guess lower end Megapixels say 3 to 4. File type MP4.

Does 960H mean anything regarding resolution.

960H is a measure of the resolution.

It indicates the number of horizontal pixels - the vertical number varies according to whether it is recording in PAL or NTSC.

The Wikipedia entry has problems but is here Wikipedia

Your best bet to find out the information that you want is probably to contact the technical depts. of several companies selling the equipment.

Whilst each will obviously try to sell you their equipment, the information that they give you should also help to decide which one is best for you (if you have not yet bought the equipment).

sorry buddy, i thought you're talking about another kind of math :)

Can you run the 4 cameras for one hour and see what space has been used


Is this a hypothetical question?

  bumpkin 19:12 28 Feb 16

X123, not hypothetical that is what I did, easiest way to find out without having having to know the ins and outs of a cows bum:-)

4 cameras all on at the same time use around 2400MB/Hour giving me around 16 Days of recording which is plenty.

  Quickbeam 22:22 28 Feb 16

Can we ask what you're going to record for 2 weeks using 4 cameras...?

At a guess. Cctv while away on holiday?
