The Link Between Intrusion Detection and Video Surveillance

By December 3, 2015 June 26th, 2019 No Comments

The terms security and surveillance are often used interchangeably when it comes to installing devices on a property. However, while each term signifies tools and methods for protecting people and property, they both have their own definitive purpose. Understanding these differences is an important facet for any consumer wanting to create the most effective combination of an intrusion detection and video surveillance system.

Intrusion Detection and Video Surveillance Defined

The first step is acknowledging the differences between video surveillance and video security. Video surveillance is the general umbrella term to describe the passive recording of events for future playback, or the continual recording for remote viewing. By itself, surveillance is generally not effective at preventing a crime from happening, unless the home or business owner just happens to be watching the video as the crime is occurring.

Intrusion Detection can be defined as “a device or software application that monitors network or system activities for malicious activities or policy violations and produces reports to a management station.” At that point you can determine if there is activity that needs to be stopped immediately.

When you include intrusion detection you will evolve your surveillance into top notch security. Intrusion detections are automatic alerts that lead a person to watch a running video surveillance monitor and determine if the activity warrants a response. Without such specialized alerts, you and your clients would not be aware of the crime taking place.

Effective Technology 

Relying solely on surveillance video cameras would only be useful in capturing an intruder or vandal after the break in occurred.  It would also help determine weak points in your security premises.

Even if you’re able to have a person watching video footage as it streams 24/7, most people suffer from fatigue when left to stare at bright monitors for too long. This fatigue can greatly impact a person’s ability to detect a sly intruder.

In contrast, when using intrusion detection devices with your security cameras, an individual is keyed to study the footage after an event has been triggered by the smart device. This means that the alerted individual will have a heightened awareness and be able to quickly see and understand whether a threat is present and, if so, react in a timely manner to prevent a would be crime from happening.


Ultimate control and a sense of security are two main goals for you and your clients. Intrusion detection systems combined with video surveillance will protect your property from unauthorized intrusion.

Demand for security products is growing because of the overall concern about security risks.
