How Much Hard Drive Space Do You Need for a Hikvision CCTV System in Solihull?

How Much Hard Drive Space Do You Need for a Hikvision CCTV System in Solihull?

One of the most common questions we get from businesses in Solihull is:

“How much storage do we actually need for our CCTV system?”

For most small commercial Hikvision CCTV systems, somewhere between 2TB and 8TB is usually enough, depending on:

• how many cameras are installed

• the recording quality

• how long footage needs to be kept

• whether the system records all the time or only when motion is detected

For example, a small office or retail unit with 4 cameras may only need a 2TB or 4TB hard drive, while larger sites with more cameras will normally require much more storage.

Choosing the correct storage setup is important because if the hard drive is too small, footage can end up being overwritten much sooner than expected.

At AddTek, we help businesses across Solihull choose the right Hikvision NVR and storage setup based on the size of the premises and how the system will actually be used day to day.

What Is an NVR?

An NVR (Network Video Recorder) is the main recording device used in modern IP CCTV systems.

It’s responsible for:

• recording footage

• storing video files

• managing camera feeds

• allowing playback and remote access

The amount of footage the system can keep depends mainly on the size of the hard drives inside the NVR.

Most Hikvision commercial systems use:

• 2TB

• 4TB

• 6TB

• 8TB

• 10TB+ surveillance drives

Generally speaking, the larger the drive, the longer footage can be stored before older recordings are overwritten.

How Long Will CCTV Footage Stay Stored?

Most businesses want footage stored for around:

• 14 days

• 30 days

• sometimes longer for higher-security sites

How long footage lasts depends on:

• the number of cameras

• recording quality

• motion settings

• recording hours

As a rough example, a recent small commercial installation completed by AddTek in Solihull used a 4TB Hikvision setup which provided around 3 weeks of footage retention across the site.

What Uses the Most Storage?

A few things make a big difference when it comes to CCTV storage.

Camera Resolution

Higher-resolution cameras create clearer footage but also use more storage space.

Common Hikvision resolutions include:

• 2MP

• 4MP

• 8MP / 4K

4K cameras look great and provide much more detail, but they fill hard drives much faster compared to standard 2MP cameras.

For commercial premises where facial detail or vehicle identification matters, higher resolution cameras are often worth it.

Number of Cameras

The more cameras connected to the system, the more storage is needed.

A small 4-camera office setup will use far less space than a warehouse with 16 or more cameras recording continuously.

This is why storage needs to be planned properly during installation rather than guessed afterwards.

Continuous Recording vs Motion Recording

This is one of the biggest factors affecting storage.

Continuous Recording

The system records 24/7.

Usually recommended for:

• warehouses

• yards

• industrial units

• higher-security commercial sites

It provides full coverage but uses much more hard drive space.

Motion Detection Recording

The cameras only record when movement is detected.

This works well for:

• offices

• quieter commercial premises

• reducing storage usage

In many cases, motion recording can massively extend how long footage is stored without needing larger drives.

What Hard Drives Should Be Used?

Commercial CCTV systems should always use surveillance-grade hard drives.

Normal desktop drives are not designed for:

• 24/7 recording

• constant read/write usage

• CCTV workloads

The most common drives used in Hikvision systems are:

• WD Purple

• Seagate SkyHawk

These are built specifically for CCTV systems and are much more reliable for long-term commercial use.

What Happens When the Storage Fills Up?

Most Hikvision NVRs automatically overwrite the oldest footage first.

That means:

• the system keeps recording

• no manual deleting is needed

• older footage is replaced automatically

The issue comes when storage is too small and footage only lasts a few days before being overwritten.

We often find businesses don’t think about storage length until they actually need to go back and review footage after an incident.

Typical Storage Guide for Commercial CCTV Systems

These figures can vary depending on:

• image quality

• recording settings

• motion detection

• retention period

Why CCTV Storage Matters for Businesses

Having enough recording history can be important for:

• theft investigations

• insurance claims

• staff incidents

• vehicle damage

• health & safety reviews

For most businesses, it’s better to slightly overestimate storage requirements rather than realise later the footage is disappearing too quickly.

Frequentlyed Questions

How long will a 4TB Hikvision NVR record for?

A 4TB Hikvision NVR will normally store between 2–4 weeks of footage for a small commercial CCTV system depending on the number of cameras and recording settings.

Is motion recording better than continuous recording?

Motion recording helps reduce storage usage and can significantly increase recording time, while continuous recording provides constant coverage for higher-security sites.

Can Hikvision NVR storage be upgraded later?

Yes. Most Hikvision systems can be upgraded with larger surveillance hard drives if additional storage is needed later on.

What is the best hard drive for a Hikvision CCTV system?

WD Purple and Seagate SkyHawk drives are among the most commonly used options because they are specifically designed for 24/7 CCTV recording.
