The use of AIVR does not require any specialist equipment, and there is no additional software to install. All you will need is a modern web browser and an internet connection. To watch HD video you will need broadband internet with sufficient bandwidth for streaming, although there are low-bandwidth and image-based options within AIVR if you experience issues with buffering. AIVR is available for mobile devices with a smaller set of features. For full details, please see https://help.aivr.video/compatibility/.

Depending on your account licence, you may be able to access more footage from a wider area. You can request access to a larger area by emailing us at support@onebigcircle.co.uk and provided details of the geographical area you want to view.

Please contact is at support@onebigcircle.co.uk if you would like to transfer your license. If you are a Network Rail Employee, please fill out an AIS Service Now ticket with the following details: your Network Rail email address and your colleague's email address. We will assume the licence cost centre will remain unchanged.

Depending on your account and organisation, you may be able to request access to other camera angles by emailing us at support@onebigcircle.co.uk and providing details of the camera views you would like to view. The camera angles available at the moment are: forward-facing, overhead, and pantograph camera view. Some routes also have downward-angled cameras and thermal imaging.

Select the AIVR session you would like to view. On the bottom right of the video player, you can select a media "Type" from the dropdown list. Select "Low Bandwidth" to view footage at a reduced resolution which will use less bandwidth. Alternatively, select "Still Images" and flip through the video still by still without reducing the video quality. If you are still experiencing issues, please contact us at support@onebigcircle.co.uk.

The blue "Search" button on the top right corner allows users to search for a geographic position, such as ELR and mileage, GPS coordinates, or a station name.

In the bottom right quarter of the application below the map on the right side of the screen, there is a tab called "History". This provides access to the video footage history at your current position. You can filter through the list based on the bearing and video-direction of the train, and selecting any item will load that session at your current position.

The accuracy of the measurement tool depends on the accuracy of the calibration. The better the calibration on the screen to the rails and the vanishing point, the more accurate the calibration will be. Please contact us at support@onebigcircle.co.uk if you would like further information or a refresher on how to calibrate and use the measurement tool.

The measurement tool is calibrated by identifying the vanishing point (point where the track appears to converge) and aligning the parallel lines to the train rails. Please contact support@onebigcircle.co.uk if you would like a refresher on how to calibrate and use the measurement tool.

Identify the vanishing point to your best ability (point where the track appear to converge) and align the parallel lines to the train rails where it is not curving in the image. If you cannot align the parallel lines with straight train rails, align them with the curved train rails as best as possible. Please contact us at support@onebigcircle.co.uk if you would like further information or a refresher on how to calibrate and use the measurement tool.

All of your annotations and measurements on the currently selected session will appear in the ‘Session Content’ tab in the bottom right quarter of the screen. You may also see items here that other users have created. When you create an annotation or measurement, you can save as either public or private. An annotation or measurement saved privately can only be viewed in AIVR by the user who created it. An annotation or measurement that was saved as public can be viewed in AIVR by any user who has access to the same AIVR workspace as the author. AIVR annotations are not accessible to non-AIVR users or the general public, however, they can be exported and shared offline with colleagues and teammates. Please contact us at support@onebigcircle.co.uk if you would like further information or a refresher on how to make and export annotations.

We cover over 90% of the network, and the coverage visible to you will depend on your organisation and account settings. The data is collected from a variety of sources including permanently installed cameras onto Network Rail Infrastructure Monitoring trains, temporary deployments of portable camera units and even by cameras deployed to passenger trains. A coverage map is available in AIVR and can be accessed by any AIVR user. If you require further information about the AIVR coverage map or have further questions about data collection, please email us at support@onebigcircle.co.uk.

If you have searched for a location and no footage was found, click the ‘enquire about data collection’ prompt which will contact our team to look into this further for you. We will first check that there is no technical mistake that means you cannot see data which should be available, and then be in touch to discuss your data collection options which may include waiting for a regular run to take place or commissioning a bespoke survey.

This will depend on the collection plan of whoever is collecting the data in your case. If you have access to footage collected by Network Rail this is typically every 4 weeks. The collection frequency depends on the track category (TCat) and the schedule can be found in the train plan for the measurement trains. TCat depends on how high risk the track is. Higher risk track is inspected more frequently.

Generally footage is uploaded to the dashboard in near real-time as the video footage is transmitted from the train via a mobile internet connection. In areas with poor signal, footage may take longer to upload. Please contact us at support@onebigcircle.co.uk if you require additional information.

This will depend on the type of AIVR technology deployed by whoever is collecting the data in your case. If you have access to data collected by Network Rail then you will find that footage from forward facing, rearward facing, overhead and underbody cameras may be available depending on your account settings. AIVR can also be used to collect thermal, infrared and high-speed underbody imagery which may be available to you depending on your account and data collection operations.

Some of the footage may be backwards facing because the train is running in the opposite direction to where the camera was fitted. Some trains have been fitted with permanent cameras at both ends, while others will only have a camera at one end of the vehicle. If you require forward facing footage and can only find backwards facing, try searching through the history of recordings https://help.aivr.video/history/. If no appropriate footage is available at your desired location please contact us at support@onebigcircle.co.uk.

You can find details of the date and time the video clip was recorded in the bottom right side of the screen under "Info". You can also find the date and time under the video clip name on the bottom left side.

Recordings containing sensitive material are archived during our automated and manual quality assurance processes. Archiving does not completely delete any footage which can subsequently be made available to trusted parties on request.

Depending on your organisation and account settings you may be able to access more footage than you currently have a view of. Please contact us at support@onebigcircle.co.uk noting your area of interest and the types of footage you are interested (FFV daytime only or FFV + Overhead).
