CCTV Storage Calculation: Saving Formulas and Storage Suggestions
Do you want to know how to calculate CCTV storage and hard drive capacity?
Formula for calculating CCTV camera storage
Storage space (GB) = Bit rate (Kbps) * 1000/8 * 3600 * 24 *
Cameras * Days / 1000,000,000
·
* 1000/8 = to convert kbps to Bytes
·
* 3600 = convert from seconds to hours
·
* 24 = convert from hour to day
·
Cameras = total number of cameras
·
Days = total number of days you want to record
You can now calculate CCTV camera storage or HDD capacity
for CCTV using the above CCTV storage calculation formula.
If you have two cameras with a maximum bit rate of 1024Kbps
and want to record continuously for seven days, use the following CCTV camera
storage calculation formula:
1024 * 1000/8 * 3600 * 24 * 2 * 7/1000 000 000 = 154.8288 GB
required storage space
This formula can also be used to calculate CCTV storage for
various brands, such as Reolink IP Camera Storage Calculator, CCTV Storage
Calculator for Samsung, Hikvision, Panasonic, Axis, Hoenywell, HD-SDI, Auetura,
Milestone, Bosch, and others.
Please keep in mind that the results of the above CCTV
storage calculator formula may not be exactly the same as your actual storage
requirements, as the CCTV camera storage calculation is affected by a variety
of factors.
What factors influence the CCTV storage calculation?
Here are the main factors to consider when calculating CCTV
storage, which may affect your CCTV camera's recording capacity.
Resolution - The higher the resolution, the greater the CCTV
camera's storage capacity in days.
Video compression is a technique that reduces the size of
the original video file formats, requiring less CCTV storage space than the
original files. H.264, MJPEG, and MPEG4 are the most popular video compression
formats.
Bitrate - A higher bitrate contributes to better video
quality, but it also means that more CCTV storage capacity is required, as you
can see from the previous CCTV storage calculation formula. It is also
influenced by resolution and compression formats. Lower bitrates are required
for lower resolution and highly compressed videos.
The number of cameras you use can also have an impact on the
CCTV storage calculation. If you use multiple cameras at the same time, you
will need more CCTV storage space.
Days - The longer the CCTV recording retention period, the
greater the CCTV storage capacity required.
In addition to these, other factors such as audio
recordings, recording modes (motion activated recording or 24/7 recording),
number of motion activities, lighting conditions of the scene, and so on can
all have an impact on the CCTV storage calculation.
Even if the storage space of the IP camera or hard disk does
not meet the required CCTV storage capacity according to the CCTV storage calculation
formula, there is no need to be concerned.
When the CCTV storage reaches its maximum capacity, the
original videos are typically overwritten by new ones. Just make a backup of
any important documents before overwriting them.
You can simply download this easy to use HDD Storage Calculator for CCTV to know how much capacity you need for your Home or Office CCTV.
