Understanding DORI Standards in Security Cameras

After all, if you ever need to identify someone suspicious on your property, blurry images might be of little use. This is when DORI, an efficient tool that enables you better to understand the features of your home and commercial security cameras, comes in. 

Ever questioned how clear the video from your security cameras needs to be? 

In Auckland alone, there were over 340,000 recorded burglaries between 2018 and 2021, according to a new Stats NZ report. Given those figures, it should come as no surprise that many Aucklanders are purchasing security cameras. 

Whether it’s for residential purposes or commercial CCTV installation, understanding the DORI standard is crucial to ensure the system provides clear and actionable footage.

However, owning a security camera alone is not enough. You have to make sure that the footage is clear enough to be helpful in the event of an emergency.

The purpose of this blog article is to provide an easy-to-understand explanation of DORI (Detection, Observation, Recognition, Identification) for security cameras. We'll go over each level's meaning, its importance, and how it might assist you in choosing the right security camera system. 

What is DORI?

DORI stands for Detection, Observation, Recognition, and Identification. It is a standard that describes how a security camera can visually detect and identify people or objects at different distances. The meaning of each part is as follows:

• Detection: The camera's capacity to identify an object in its field of vision, is essential for early warning.
• Observation: The capacity to watch an object once it has been identified in order to learn more about its motion or activity.
• Recognition: At this point, you can identify what or who the object is since the camera can capture clearer details.
• Identification: The most in-depth level, which gives you the ability to observe and recognise particular characteristics or traits of the object or person.

Knowing all of this makes it easier to choose a CCTV camera that meets your unique security requirements and ensures efficient surveillance and security.

The Importance of DORI in Security Cameras

Why is DORI important to Aucklanders? Here’s a breakdown:

• Enhanced Accuracy: DORI-compliant cameras provide accurate details at the right distances, lowering false alarms and boosting dependability.
• Optimal Placement: Having a thorough understanding of DORI capabilities helps in the strategic placement of cameras to efficiently cover important regions.
• Improved Evidence Collection: DORI-enabled cameras offer crisper photos in the unfortunate case of a security incident, facilitating faster legal and resolution procedures.

NOTE: It is important to understand that the DORI standard offers a powerful way to boost security for homes and businesses.

Different Levels of DORI

Let's examine each DORI level and what it means for your security cameras.

Detection (25 PPM)

At this basic level, the security camera can simply detect movement and tell you something is happening in the frame. You might make out a shape or a figure, but indistinct details like clothes or facial features would be visible. The detection level allows for reliable and easy determination of whether a person or vehicle is present. For setting off motion alerts or obtaining a broad sense of activity, this might be adequate.

Observation (62 PPM)

Some details are beginning to emerge at this point. You might be able to identify general characteristics, like clothing colour, or differentiate between an animal and a person. The observation level gives characteristic details of an individual, such as distinctive clothing, while allowing a view of the activity surrounding an incident. It would still be difficult to identify specific people or to obtain license plates, though.

Recognition (125 PPM)

At this level, you can identify well-known faces with a fair amount of confidence. If it's not a delivery person, you might be able to identify it as your neighbour. The recognition level determines with a high degree of certainty whether an individual shown is the same as someone that has been seen before. In ideal lighting circumstances, it might also be able to recognize license plates.

Identification (250 PPM)

This is the highest level of detail, which allows you to positively identify individuals beyond a reasonable doubt. Clear and distinct facial features, details of clothing, and license plates emerge. The identification level enables the identity of an individual beyond a reasonable doubt. This level is perfect for circumstances where getting clear evidence is essential.

DORI in Action

Let’s explore how DORI functions in a real-life scenario (home setting):

Explanation of the Scenario

• Detection: The moment the camera detects movement at your gate, it notifies you that someone is there.
• Observation: The camera follows the subject as they approach, giving them constant visual cues and evaluating their conduct.
• Recognition: The system determines if the person is an unknown guest or someone you know, such as a delivery person.
• Identification: The camera can capture specific photos, such as clothes or facial traits, if necessary to verify an individual's identification or report questionable activities.

This hypothetical situation highlights how important DORI is to improving home security. DORI makes sure that nothing is overlooked by carefully examining each stage—detection, observation, recognition, and identification.
