Cloud vs Local Video Storage
Cloud vs local video storage for businesses — how off-site and on-site recording differ in reliability, cost, access and internet dependence.
Video has to be stored somewhere, and for a commercial camera system there are two main choices: on a recorder at the property, or on remote servers in the cloud. Many systems use a combination of both. This article explains how the two differ, so a business can choose based on its property rather than on a sales pitch.
Local Storage
Local storage means the video is recorded on a device at the property — usually a network video recorder with hard drives. The footage is in the building, the recording does not depend on the internet, and playback is fast because the video does not have to travel anywhere.
The limits of local storage are physical. The recorder has a fixed amount of storage, and when it fills, the oldest footage is overwritten. The recorder can be damaged or taken, and with it the footage. And the recorder needs maintenance — drives wear out and need replacing.
Cloud Storage
Cloud storage means the video is sent over the internet to remote servers, where it is stored and made available through an app or a browser. The footage is off site, so it is not lost if the on-site equipment is damaged. Several properties can be viewed in one place, and the storage can be adjusted without buying new hardware.
The limits of cloud storage are the internet connection and the ongoing service. Every camera sends video upward, so the property's upload speed sets the limit on how many cameras can send what quality. And the service is a running cost, priced around the storage and retention the business uses.
Hybrid Storage
A hybrid system records locally and sends a copy, or selected footage, to the cloud. That combination gives the off-site protection of the cloud without making the whole system dependent on the internet. If the internet drops, local recording continues, and the cloud copy resumes when the connection returns.
Hybrid storage suits many commercial properties, especially larger ones. Local recording handles the full video, and the cloud handles the important events or the backup. The design should state clearly what is stored where, so the business knows what survives an outage and what does not.
A Practical Comparison
Local storage: no internet dependence for recording, fast playback, fixed capacity, footage at risk if the recorder is damaged. Cloud storage: off-site protection, multi-site viewing, flexible capacity, dependent on upload speed, ongoing service cost. Hybrid: local recording plus cloud backup, the most resilient option for many properties.
The comparison should be made with the property's internet connection in mind. A property with a slow upload connection cannot run a full cloud system, however attractive it sounds. The upload speed should be measured on site before the decision is made.
Choosing for Your Property
A small property with a strong internet connection may suit full cloud storage. A large property with many cameras may suit local storage, or a hybrid system that keeps the full video on site and sends the important events to the cloud. A business with several locations may suit cloud storage for the multi-site view alone.
The choice should be made during design, with the upload speed measured, the retention period decided, and the ongoing cost understood. A decision made on those facts is a decision that will still look right in a year.
Frequently Asked Questions
What is the difference between cloud and local video storage?
Local storage records video on a device at the property, such as a network video recorder. Cloud storage sends video over the internet to remote servers. Local storage does not depend on the internet for recording; cloud storage keeps footage off site and allows multi-site viewing.
Is cloud video storage more reliable than local storage?
It depends on what reliability means. Cloud storage protects footage from damage to on-site equipment, but it depends on the internet connection. Local storage keeps recording without the internet, but the footage is at risk if the recorder is damaged. A hybrid system gives the most resilience for many properties.
Does cloud storage need a fast internet connection?
Yes, especially upload speed. Every camera sends video to the cloud, so the property's upload connection has to carry the total of all cameras. A hybrid system suits properties with limited upload speed.
Can I use both cloud and local storage?
Yes. A hybrid system records locally and sends a copy or selected footage to the cloud. Local recording continues if the internet drops, and the cloud copy resumes when the connection returns.
