NVR vs cloud CCTV: how to choose and what to tell customers

Cloud video is no longer a niche idea. Customers see subscription cameras advertised and ask whether they still need a recorder at all. Some installers dismiss the idea, while others treat cloud as the obvious future. Neither view helps the customer. The right answer depends on the site's connection, the number of cameras, how long footage must be kept and who will run the system.

This guide compares the options from an installer's point of view, including how each one affects your income.

The three main models

Local recording. Cameras record to an NVR, DVR or on-premises server. Footage stays on site. Remote viewing, if used, is an additional connection.

Cloud recording. Cameras send video directly or through a small gateway to a provider's servers. The customer pays a subscription, usually per camera, and it often varies by retention period.

Hybrid. Footage records locally, often on the camera's own storage or a small appliance, and the cloud stores metadata, thumbnails, important clips or selected streams. Management occurs through a cloud portal.

The word "cloud" is used loosely in marketing. A recorder with a phone app that connects through the manufacturer's servers is not cloud recording. Footage is still stored on the local recorder. Be clear about this when you talk to customers.

Side-by-side comparison

These are tendencies. Specific products differ, so compare the actual offer.

Do the bandwidth sums first

Bandwidth often settles the question. A camera recording continuously to the cloud at 2 Mbps needs that upload capacity all day, every day.

Total upload = cameras × bitrate

So 8 cameras × 2 Mbps = 16 Mbps of constant upload. On a business connection offering 20 Mbps upload, little is left for anything else. Many connections also have a monthly data allowance or a fair-use limit, and 16 Mbps continuously is over 5 TB per month.

The calculation: 16 Mbps × 86,400 × 30 ÷ 8 ÷ 1,000,000 = about 5.2 TB.

Local cameras don't have this problem, because the video stays on the network. Many cloud systems reduce it by recording only on events, using very efficient compression or storing most of the video on the camera, and only uploading when needed. Find out exactly how the product uses bandwidth, and measure the site's actual upload speed, instead of trusting the plan's name.

Compare costs over five years

Sticker prices don't tell the whole story. Compare total cost over the period the customer plans to use the system, with figures from real quotes. Here's a template with invented numbers.

In this invented case, local recording works out cheaper, but your own numbers may say otherwise. A small number of cameras across many sites can favour cloud, especially where IT support is expensive. Long retention tends to favour local. Run the comparison for each serious project.

When local recording fits best

• Sites with poor or limited upload speeds
• Long retention requirements, or high-resolution cameras
• Many cameras on one site
• Customers who want no recurring subscription
• Sites that need footage to remain on premises because of policy or sensitivity
• Remote locations with unreliable connections

Reduce the weaknesses of local recording by securing the recorder in a locked room, keeping it out of sight and backing up critical footage. Our storage guide explains how to size it.

When cloud fits best

• Businesses with many small sites and little local IT help, such as franchise chains
• Sites with few cameras and good connections
• Customers who want updates and maintenance handled for them
• Customers worried about a recorder being stolen
• Organisations that want central user management and audit logs
• Sites where footage needs to be viewed quickly by people in many locations

When hybrid fits best

Hybrid systems try to give you central management without the full bandwidth cost. It can be a good compromise for multi-site retail or offices. Check what happens if the internet fails, how long local footage lasts, and how much the subscription costs if you scale up.

Questions to ask any cloud provider

Before recommending a platform, get clear answers to these:

1. What happens if the internet fails? Is footage stored locally and uploaded later?
2. What happens if the subscription ends? Do cameras keep working? Can they be used with another system? Some can't.
3. How much does retention cost? Compare 30, 60 and 90 days.
4. What's the upload requirement per camera at the settings needed?
5. Where is the data stored? Does this meet the customer's requirements?
6. Who can access footage? Can provider staff see it, and how is that controlled?
7. Is it encrypted in transit and at rest?
8. How can footage be exported? Can it be kept for an investigation?
9. What's the price after the first term? Are there any price increase limits?
10. What certifications and audit reports exist? Ask for them if the customer needs them.
11. Is the product permitted for this customer? Check local rules and any procurement restrictions.

Privacy and security

Neither option is automatically safer. A well-run cloud service can be better secured than a recorder with a default password, but it also places footage in a third party's hands. A local recorder keeps footage on site but relies on someone to keep it updated and physically secure.

Questions of data protection and cross-border transfer may also apply where cloud storage is used, so a business with strict obligations should get advice. See our cyber security guide for how to harden any system.

What it means for your business

Your choice affects how you make money.

Local systems bring larger hardware sales up front, plus maintenance visits. Recurring income depends on selling a maintenance contract.

Cloud systems often involve smaller hardware margins, but some vendors offer recurring partner income. You may have fewer visits, and customers may be more tied to the vendor than to you.

Questions for you to ask:

• Who owns the customer relationship: you or the vendor?
• Can you set your own price?
• Does the vendor sell directly and compete with you?
• What happens to your income if the customer cancels?
• What training and support do partners get?

You don't need to pick just one approach. Many companies offer local systems as a default, plus one cloud or hybrid product for customers who suit it.

How to explain the choice

Use plain language and specific numbers.

"With a recorder, you pay more today, and footage stays on your premises. It keeps recording if the internet goes down, and there's no monthly fee, but we should keep it locked away. With cloud, the footage is safe off site even if equipment is stolen, and you pay monthly for each camera. Your current upload speed would need upgrading to handle it. For your eight cameras over five years, here's how the costs compare."

This kind of explanation is far more useful than telling a customer that one technology is simply better.

Migrating an existing system

If a customer wants to move toward cloud or hybrid:

• Check whether existing cameras are supported. Many platforms only support their own or a few listed cameras.
• Use a gateway if it's available.
• Pilot at one site, and measure bandwidth and retention.
• Keep the old system running until the new one has proven itself.
• Export anything that must be kept before removing old drives.

Decision guide

1. Measure real upload speed. If it can't carry the required video, rule out full cloud unless it's upgraded or the design changes.
2. Note retention and camera count. Long retention or lots of high-resolution cameras favour local.
3. Look at the number of sites and IT support. Many small sites favour cloud or hybrid.
4. Check legal and policy limits. Some customers can't use certain vendors or data locations.
5. Compare five-year costs. Include subscriptions, maintenance and internet upgrades.
6. Check who'd be responsible for ongoing support. Then quote the best option, and offer the alternative if it's close.

Recommending the right tool, rather than whichever one you happen to prefer, is a large part of what makes customers trust you.
