Secure Incident Management Software.

G4 Viewer Plus is Gatekeeper’s industry leading secure incident management software that provides a comprehensive set of features for managing video recorded with Gatekeeper’s line of G Series Mobile DVRs. Users can easily find incidents, make clips of incidents, blur selected regions in the video, display the path of the vehicle on a map, in addition to many other features, making the management of video intuitive and easy.

When paired with the wireless capabilities in Gatekeeper’s latest hybrid DVRs, G4 Viewer Plus enables real-time access to live streaming video, vehicle location and status, allowing users to quickly find, save and share the video files of critical incidents as they happen. This empowers users with the information they need to make swift decisions based on clear evidence.

High resolution video, synchronized with date and time stamps, precise GPS location data, integrated with accurate event information on map, coupled with crucial vehicle sensor data – all combine to give a total picture of fleet events. Improve fleet safety, protect vehicles from misuse, minimize false liability claims and optimize fleet efficiencies – it’s that easy, with the help of G4 Viewer Plus.

Video Playback with Interactive Maps and Geo-Jump

Playback video from multiple cameras simultaneously at different speeds in both forward and reverse directions –pause, step through video frame by frame, and save snapshots of any event of interest from any combination of cameras at any time. Video playback is fully integrated with an interactive map display which shows the vehicle track and marks events of interest directly on the map. Quickly Geo-Jump to any location by clicking on the map to show the associated video and events. Similarly viewing video of specific events is just as easy as clicking on the event itself, either on the map or from the event list – thus enabling users to browse video and review incidents very intuitively.

Share Video in Industry Standard Formats

G4 Viewer Plus allows video clips of any desired length to be exported either in native format (for sharing with other G4 Viewer Plus users), or as industry standard AVI files (which can be played back using any standard media player, such as the Windows Media Player software found in Microsoft Windows). Another unique aspect of G4 Viewer Plus is the ability to share video securely using a password protected Mini-Player container. This feature allows users to export video as a self-contained, password protected, standard Windows executable file, which incorporates the video and all associated mapping, sensor and GPS data, along with a built-in Mini-Player component. This makes it easy for users to share video together with complete associated situational data, even to recipients who do not have G4 Viewer Plus installed.

Intelligent Search and View Options

G4 Viewer Plus has intelligent search options which allow for easy incident identification, thus enabling the user to find the videos that matter in the shortest possible time. Besides filtering by date and recent video, the user can also search using a unique combination of parameters including vehicle speed, geo fence boundaries, and specific sensor events. As an example, this feature could enable a school transport manager to quickly identify when and where children entered or exited the bus, in case of a reported missing child. Fleet administrators could also easily monitor driving habits (harsh braking, acceleration, cornering, excessive speed) and build risk profiles over time thus providing valuable feedback to drivers, as well as improving safety and performance across the entire fleet.

Collaborate over the Cloud using Industry Standard File Sharing Services

G4 Viewer Plus allows users to easily leverage industry standard file sharing services (such as DropBox, Google Drive or Microsoft OneDrive[1]) for sharing video seamlessly with teams spread across multiple geographic locations. Flexible file saving options enable the user to quickly export video to designated cloud-shared folders, so that the video can be synchronized with the cloud repository and automatically downloaded to the recipients

Advanced Wireless Capabilities Using WiFi

AUTOWAKE and MAXLOCATE – Wireless Control of Vehicle DVR/WiFi Equipment

G4 Viewer Plus works with Gatekeeper’s unique fleet control applications to manage video in vehicles remotely as part of Gatekeeper’s Advanced Wireless Solutions suite. MAXLOCATE utilizes a secure low-power wireless protocol to communicate with in-yard vehicles – providing a vehicle-presence dashboard that enables users to tell at a glance which vehicles are in or out of the yard. This complements vehicle GPS tracking to provide transport

managers with total visibility on the location of vehicles in their fleet – even when parked within covered bus yards where there is typically limited GPS coverage. AUTOWAKE allows users to remotely power on/off the DVR and WiFi radio equipment of any in-yard vehicle that is parked within the yard WiFi coverage area. These unique features provide transport managers with powerful time-saving tools allowing them quick access to recorded video from “online” vehicles over WiFi and helping to improve the productivity of post-trip inspections.

Remote Access to Video in Vehicles

G4 Viewer Plus enables users to perform post-trip inspections of recorded video (on in-yard vehicles equipped with WiFi connectivity) remotely from the comfort of their office. Users can access any “online” vehicle and directly view recorded video from any camera channel. Flexible options allow the user to search for video either by time period or events of interest, and to select either all or a portion of video to download. By using the WiFi link for in-yard downloads, large amounts of video data can be freely transferred off the vehicle very quickly. G4 Viewer Plus has been designed to help improve operational efficiencies while saving time and valuable resources – no more running to each vehicle to retrieve the video

Automatic Download Scheduling

With G4 Viewer Plus, video downloading has never been easier. Flexible scheduling provides for automated unattended downloads each time the vehicle returns to the yard. At the same time, powerful options allow users to define exactly which video should be downloaded – through a combination of time period and sensor/events of interest – while configurable pre and post event recording settings ensure that a complete view of the incident is always captured. As an example, school transport managers could configure G4 Viewer Plus to automatically download only the video of speeding/harsh braking events as well as video from each stop the bus made. This allows them to easily review and identify incidents for escalation without having to browse through hours of recorded video, thus dramatically improving efficiency and response time.


Access Live Video from Vehicles at Any Time

Get immediate access to actual live video footage from any of the cameras in vehicles which are equipped with cellular connectivity. G4 Viewer Plus is designed to work seamlessly with the state-of-the-art dual-streaming technology built into Gatekeeper G Series DVRs – this allows access to a bandwidth-optimized secondary video stream for real-time viewing, while the DVR continues to record full resolution video. G4 Viewer Plus has multiple camera viewing options, and provides a flexible video display screen that can be configured to display up to 36 cameras from any combination of vehicles across the entire fleet.

Comprehensive 360-Degree Fleet Management

Never be in the dark again – G4 Viewer Plus gives users access to video and status information about any vehicle in their fleet at any time. Powerful fleet management settings enable remote access to each individual vehicle’s video, location, status, and digital video recorder settings. Users can create an accurate representation of their entire fleet, with unlimited nested sub-zones, and delegate authority to access zones and sub-fleets using the comprehensive roles and user management features in G4 Viewer Plus.

Immediate Access to Vehicle GPS Location Data

G4 Viewer Plus provides access to precise vehicle GPS location data. Flexible configuration options allow administrators to set different data transmission intervals for each individual vehicle to optimize bandwidth usage and meet unique monitoring/reporting requirements. G4 Viewer Plus displays the entire fleet on an interactive map, and provides an intuitive representation of crucial data such as speed, G-forces, device temperature, and operating voltage using a standard color-coded graphical format, so that users can easily identify issues at a single glance.
