THE BUYING GUIDE

Plan retention before you buy capacity.

Surveillance storage needs to fit the host equipment as well as the desired recording period. Check whether the product is a drive, a storage appliance or an accessory, then compare supported interfaces and capacity limits. Retention depends on actual video bitrate and recording hours; raw capacity alone does not describe the whole recording system.

Start with the application.

Describe the job, the installation environment and the equipment already on site. Compare the exact model specifications before choosing; a collection name alone does not establish compatibility or included features.

Four checks before you choose.

Start with the details that affect your installation.

01 / HOST

Device & interface support

Check the recorder or server compatibility information, connection type, drive dimensions and allowed capacities.

02 / WORKLOAD

Recording requirements

Compare the workload expected from the system, including continuous recording, playback and the number of streams.

03 / CAPACITY

Usable space & retention

Estimate video data, then allow for formatting, audio and any redundancy arrangement.

04 / RESILIENCE

Redundancy & recovery

Check whether the host supports the intended disk configuration. RAID does not replace an appropriate backup or export process.

PLAN YOUR RECORDING TIME

How much storage
will you need?

Start with an estimate, then check the recorder’s drive limits and your site’s actual video settings.

ESTIMATED VIDEO STORAGE4.84 TB

Video only, in decimal TB. Allow extra capacity for formatting, audio and any RAID configuration. Variable bitrate and event recording change actual retention. This estimate does not determine which drives an NVR supports.

BEFORE YOU ORDER

A few useful answers.

Planning your installation?
Talk through your requirements with us ↗

Will any HDD work in my recorder?

Check the recorder manufacturer compatibility information and firmware, bay size, interface and capacity limits.

Does the displayed capacity equal video capacity?

Usable recording space can differ because of formatting, system data and the selected storage configuration.

Is RAID available on every storage product?

No. Check the exact host, supported RAID modes, drive count and configuration requirements.

Can I estimate days from capacity alone?

You also need the number of streams, average bitrate and recording schedule. The estimate below covers video data only.
