How to access your CCTV from a computer or web browser

Many people can access their CCTV cameras easily from a mobile phone but struggle when trying to view the same system from a computer or web browser. This guide explains why that happens, how CCTV access from a computer actually works today, and what options are realistically available.

Not all CCTV systems support modern browsers. Some rely on older technologies that are no longer widely supported. Understanding this early can save time and frustration.

How CCTV access from a computer works

CCTV systems can be accessed from a computer in several different ways, depending on the age and design of the system.

Some newer systems provide a modern web interface or desktop application. Older systems often rely on browser plugins that were designed for Internet Explorer. Mobile apps usually work differently and do not rely on browser technology at all.

Because of this, the method that works on a phone is not always available on a computer.

Why CCTV often works on a phone but not in a web browser

Mobile apps typically connect to CCTV systems using vendor cloud or P2P services. These services bypass browser limitations and do not rely on plugins.

Web browser access, especially for older systems, often depends on legacy components that modern browsers no longer support. This is why a system can appear fully functional on a phone while failing completely on a computer.

Why some CCTV systems no longer work in modern browsers

Many older CCTV platforms were designed to work only with Internet Explorer using ActiveX controls. Modern browsers have removed support for this technology for security reasons.

As a result, video feeds may remain blank, controls may not load, or the system may appear broken even though the cameras are working correctly.

When Internet Explorer mode is still required

In some cases, Microsoft Edge can still be used to access older CCTV systems by running the site in Internet Explorer mode.

This is a compatibility feature intended for legacy systems. It is not a modern solution and should be treated as a temporary workaround rather than a long-term approach.

Correct way to access legacy CCTV systems using Edge IE mode

To access a legacy CCTV system that relies on Internet Explorer technology:

Open Microsoft Edge normally.

Navigate to the CCTV system website. (for example: https://www.autonat.com/)

Use the Edge menu to reload the page in Internet Explorer mode.

When this is active, a banner will appear confirming that the page is running in IE mode.

Why CCTV plugins appear installed but do not work

ActiveX plugins do not appear as browser extensions and do not show up in normal add-on lists.

They only load when:

The browser is running in Internet Explorer mode

The page is allowed to run blocked content

In some cases, more than one plugin is required, such as a connection component and a video playback component. Each must be installed separately, with the browser fully closed during installation.

Common reasons CCTV does not load on a computer

Some of the most common causes include:

The page opened in normal browser mode instead of IE mode

The browser was not fully closed during plugin installation

Only one of multiple required plugins was installed

Blocked ActiveX prompts were not allowed

These issues often look identical on screen, which makes troubleshooting confusing.

Important limitations to be aware of

Legacy browser access depends on outdated technology. It may stop working after browser updates, Windows updates, or security changes.

If access from a computer is business-critical, it is sensible to review alternative access methods or system upgrades rather than relying indefinitely on browser compatibility workarounds.

When an assesment is required

When assessment is recommended

If you are unsure whether your CCTV system supports modern access methods, or if browser access is unreliable, an assessment can help determine:

Whether a desktop client is available

Whether firmware updates are possible

Whether alternative access methods exist

Whether system replacement should be considered
