AI Security Cameras

What Is Edge Processing?

Many modern AI cameras perform analytics directly within the camera itself. This is known as edge AI, where processing happens inside the camera hardware rather than in a remote server or cloud system. Some newer generations of NVRs have “AI by NVR” technology that can do analysis with third-party and ONVIF cameras.

Edge-based analytics offer several advantages:

• faster detection
• lower bandwidth usage
• improved privacy
• no subscription fees for cloud processing

How AI Detection Works

Traditional surveillance systems use pixel-based motion detection which can alert whenever pixels change in the video stream. When enough pixels change, the system interprets that change as motion and begins recording or sending alerts. AI detection adds an additional layer of intelligence.

Using machine learning models and algorithms, the camera analyzes shapes, movement patterns, and object characteristics to determine what exactly is present in the scene. Once objects are recognized, the system can apply detection rules such as:

• crossing a virtual line
• entering a restricted area
• remaining in a location for too long
• appearing or disappearing within a defined region

Because the system understands what it is seeing, it can ignore irrelevant motion while focusing on important events.

Key AI Detection Features

AI surveillance cameras support a variety of intelligent detection capabilities designed to improve monitoring accuracy. Be sure to check the description of the camera you're interested in to know which AI detection features it supports.

Human Detection

Human detection allows cameras to identify humans and their movement while ignoring other types of motion such as animals, shadows, or weather. This significantly reduces false alerts while ensuring notifications and recordings are triggered only by activity from humans.

Vehicle Detection

Vehicle detection enables cameras to recognize cars, trucks, and other vehicles entering or leaving a monitored area. This feature is commonly used in parking lots, driveways, gated entrances, and loading docks.

Tripwire Detection

Tripwire detection allows users to draw a virtual line within the camera's view. When a human or vehicle crosses the line, the system triggers recording.

Common uses include monitoring:

• building entrances
• property boundaries
• parking lot access points
• restricted areas and hallways

Intrusion Detection

Intrusion detection monitors a defined area, usually a shape drawn by the user, within the camera's field of view. When a human or vehicle enters the zone, the camera generates an alert and starts recording.

This feature is useful for monitoring:

• restricted zones
• storage areas
• secure doorways
• after-hours access points

Missing Object Detection

Missing object detection alerts users when an item that was previously present in a defined area disappears.

Businesses often use this feature to monitor:

• inventory displays
• equipment storage
• package pickup locations

Abandoned Object Detection

Abandoned object detection identifies items that remain in a location longer than expected.

This feature can be used to monitor suspicious activity or unattended objects in public areas such as:

• airport terminals
• train or subway stations
• bus stops

People Counting

People counting analytics measure how many individuals enter or exit a location. Businesses are able to use this data to analyze foot traffic and occupancy patterns for promotions and staffing.

This feature is widely used in:

• retail stores
• gas stations
• event venues
• office buildings
• apartment complexes

Face Detection

Face detection allows the camera to identify when a human face appears within the scene. When a face is detected, the system can capture a snapshot and generate an alert. Higher-end cameras and NVRs also have face detection databases that allow for whitelisting and blacklisting people to trigger recording, alarms, or send signals to alarm panels and door strikes. Face detection cameras are best used with an NVR that also support it.

Benefits of AI Security Cameras

AI surveillance systems provide clear advantages over traditional motion detection, especially in accuracy, speed, and usability.

• Improved Accuracy: Instead of triggering alerts for any pixel change, AI cameras identify people, vehicles, and behaviors, which significantly reduces false notifications.
• Faster Review: AI cameras allow for faster investigations by letting you search footage based on events rather than manually sifting through hours of continuous recording. Combined with custom rule-based alerts like intrusion or line crossing, this paves the way for more proactive security.
• Useful Data: Beyond security, features like people counting provide useful operational insights, helping businesses understand traffic patterns and improve decision-making.
