Nirovision Glossary

Lorem Ipsum

Activity

Activity refers to a view within the Nirovision platform that shows a timeline of all events where any known or unknown identity was captured on camera.

Alarms

Alarms are activities that you want to be notified about. Alarms can be configured in the Nirovision platform.

Analog cameras

These are older style cameras that send video over cable to VCRs or DVRs. Nirovision is not compatible with these types of cameras. We recommend IP cameras (preferably ONVIF) to get the best possible experience with Nirovision.

API

API is the acronym for Application Programming Interface, which is a software intermediary that allows two applications to talk to each other. Nirovision has an API that allows 3rd party integrations.

AWS

Our cloud infrastructure provider is Amazon Web Services (AWS), with all data being stored and transited solely in the AWS Sydney Availability Zone. In 2019, the Australian Cyber Security Centre (ACSC) certified AWS for hosting Australian Government data classified up to the PROTECTED classification level.

Biometric data

Biometric data describes any metrics related to human features. In the case of Nirovision this includes things like a person’s face and other data that you add such as a person’s name, title, or relationship to your business (customer, employee). An identity in Nirovision is made up of biometric data.

Camera resolution

The amount of detail that the camera can capture is called the resolution, and it is measured in pixels. The more pixels a camera has, the more detail it can capture and the larger pictures can be without becoming blurry or grainy.

720p works great for most applications, 1080p is our most popular resolution. There’s no need to go up to 4K, as there’s diminishing returns in increasing resolution: a 100px face on a 4K image is often very grainy compared to a 100px face on a 1080p image, since the subject is much nearer.

Cloud

Cloud computing means storing and accessing data and programs over the Internet instead of your computer’s hard drive. Nirovision uses the cloud to …

Confidence

This is a filter within the Nirovision web and phone app that allows users to filter activities to show high or low confidence with identity matches.

Deep Learning

Deep learning is a subset of machine learning where artificial neural networks, algorithms inspired by the human brain, learn from large amounts of data. Deep learning allows machines to solve complex problems even when using a data set that is very diverse, unstructured and inter-connected.

Distributor

A security distributor is a wholesaler who has exclusive rights to market, within a given territory, the goods of a manufacturer or company. In the case of Nirovision, distributors supply integrators with the hardware needed to set up and run Nirovision.

Encoded data

This term or the term *Encoded H.264* is often used when discussing recommended camera settings. This is about video compression; the process of converting digital video into a format that takes up less capacity when it is stored or transmitted.

H. 264 is an industry standard however Nirovision is also working on H.265 support.

Encryption

Encryption is a way of scrambling data so that only authorised parties can understand the information. Nirovision uses encryption when ….

Facial recognition

Facial recognition is a way of recognising a human face through technology. Facial recognition software such as Nirovision uses biometrics to map facial features from a photograph or video. It compares the information with a database of known faces to find a match.

Frame rate

Frame rate is discussed when talking about camera settings. Frame rate is the speed at which images are shown, or how fast you “flip” through a book and it’s usually expressed as “frames per second,” or FPS. Each image represents a frame, so if a video is captured and played back at 20fps, that means each second of video shows 20 distinct still images. Here at Nirovision we recommend a frame rate of 15/20 fps.

GPU

A graphics processing unit (GPU) is a specialised electronic circuit designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device. GPUs are used in embedded systems, mobile phones, personal computers, workstations, and game consoles. Nirovision requires a server with an Intel Core i5 Processor or better.

Identity

An identity is what we call a set of biometric data that separates one person from another. These identities live within the identity database. Identities don’t require a person’s name to be stored in our system, so you can use any naming convention of your choice eg. Customer 3427

Identity database

This is where you add, manage and remove identities in the Nirovision platform.

Inception by Inner Range

A cutting-edge, native web-based access control and intruder detection system, designed for light-to-medium commercial installations. Nirovision is one of the first facial recognition products to take advantage of Inception’s new biometric credential features. The integration allows users to unlock doors with their face via a camera.

Integrator

A integrator essentially links various subsystems to provide security throughout an organisation. Integrators work with Nirovision to offer our product as either a stand alone solution or link Nirovision with other systems.

IP camera

An Internet Protocol camera, or IP camera, is a type of digital video camera that receives control data and sends image data via the Internet.

IP Camera agnostic

This term is used when discussing how Nirovision works with many different IP cameras.

Labels

This is how you group identities. You can personalise labels by colours. This allows you to search activity by identity and customise alerts eg. Send an alert if someone with the label Contractor is captured on camera.

Locations

Locations refers to the physical location (street address) of your cameras. With Nirovision you can have multiple locations.

Low latency

Low latency describes a computer network that is optimised to process a very high volume of data messages with minimal delay. With on-premises server, Nirovision provides low latency access to your camera streams.

Match

When Nirovision maps facial features from a photograph or video, it compares the information with the customer’s identity database of known faces to find a match.

Metadata

Metadata summarises basic information about an identity. For example, you can add metadata such as Last seen, Visits this month, Parking access, Welcome drink etc. An organisation can decide what metadata to add to an identity.

Model

Every time you create or update an identity using our apps, you update your model, and this newly generated model will automatically be synced across locations. Every on-premise server will then download the updated model and start using it for predictions straightaway.

Model updates adjust the system’s capability to make predictions. As a result, the accuracy of the system depends on the quality of your identities, which depends on the quality of composing faces, and the quality of faces detected in your cameras’ stream.

Multi-platform software

This refers to computer software that can used across multiple computing platforms. Nirovision is available on mobile, tablet, desktop and TV making the platform accessible wherever you are.

Notification

Email and/or app notification that notifies you when an alarm you set up has been triggered.

Nx Witness

Nx Witness is an open IP video management system (VMS) that integrates with Nirovision. Nx Witness customers can add Nirovision for a range of enhanced features within the Nx Witness VMS.

On-premises

On-premises software is installed and runs on computers on the premises of the person or organisation using the software, rather than at a remote facility or cloud.

ONVIF

ONVIF creates a standard for how IP products within video surveillance and other physical security areas can communicate with each other. If you have ONVIF cameras you only need a Server to use Nirovision.

Server

A server is a computer device that runs the Nirovision software.

Shutter speed

In digital photography the shutter speed is the unit of measurement which determines how long the shutter remains open as the picture is taken. It’s one of three elements that affect how light or dark an image is (called exposure). We recommend 1/30s shutter speed as a minimum for image quality purposes. 1/100s is usually a sweet spot.

Snooze alerts

This is a feature within Nirovision that allows a user to pause alert notifications for a set period of time.

Team members

Team members are the people within your organisation that have access to Nirovision. It also displays their level of access.

Thermal camera

This is a particular type of camera that is able to perform temperature readings. When integrated with the Nirovision platform, temperature readings can be linked with an identity and selected users notified.
