Video Surveillance Software



The Longwatch Video Surveillance platform is a complete stand-alone video monitoring solution that can be integrated into existing process control systems. The system is composed of industrial grade software and video recording hardware along with a flexible ‘thin client’ viewer interface. The package includes multiple process control interfaces based on industry standards such as OPC and MODBUS TCP. These interfaces allow for complete control of the video system through existing SCADA, DCS, or MES systems. Longwatch Video Surveillance is comprised of two components: the Video Control Center (VCC) and Longwatch Video Engines (LVEs).

The VCC is provided for administration and viewing of all cameras on the network. The VCC provides an easy to configure and intuitive interface for online system configuration from a centralized location.

The LVE component is a DVR that can be provided on a pre-configured industrial-hardened appliance or as software-only to be installed in any Windows or virtual environment. Along with video recording and event based video capture, the LVE is designed to communicate with PLC or RTU devices. MODBUS TCP commands can be sent to the LVE to arm/disarm the system, turn recording on/off, take a snapshot or move the camera to a specific location. The Video Engine provides advanced bandwidth management allowing video to be sent back the control room on networks as low as 9600 baud. Video Engines can be distributed to remote locations allowing all of your cameras to operate independently and autonomously without a constant network connection.

The Longwatch Video Surveillance system is a family of software-driven, integrated modules that provides video collection, archiving, and alarming over a distributed system architecture.

The system was designed to handle a wide variety of networks, from state-of-the-art fiber networks, to legacy proprietary networks found in supervisory control (SCADA), programmable controller (PLC/HMI), and other automation control networks.

Longwatch eliminates the need to install costly broadband or optical networks. Yet, for facilities that already have the benefit of high-speed networks, Longwatch extends the useful life of those resources, creating a better return on investment.

Distributed System Architecture


Longwatch Video Control Center (VCC)

The Longwatch Video Surveillance software package is the heart of the Longwatch system. It provides complete Digital Video Recording (DVR) capabilities for any number of cameras connected to the Longwatch network. Video archives can be configured to store clips across the system in a single secure location for further viewing and analysis. Video can be streamed and stored at user-configurable resolutions and frame-rates to allow for extremely flexible bandwidth and storage infrastructure.

Remote Monitoring

Longwatch Video Engine (LVE)

The Longwatch Video Engine (LVE) software is the workhorse of the Longwatch system. It can be install on any Windows operating system or virtual environment. The LVE provides “recording at the edge” capability, including:

  • Digital Video Recording (DVR) – Using local storage for safety, security, and scalability.DVR video can be uploaded to a central server for archiving and further viewing. Remote clip extraction helps you quickly identify issues.
  • User-configurable resolution and frame rates – Multiple videos streams are created from a single camera providing live video, snapshots, video clips, and recorded video all independently configurable for resolution, frame rate, and quality.
  • Event detection – Events triggered by the PLC/RTU, hard wired inputs or built-in video analytics, are sent automatically to the Video Control Center to be dispersed to HMI screens, email addresses, or cellphones.
  • Autonomous operation – The LVE keeps running even if the network is unavailable. That means you don’t lose any video or events. When the network recovers, the LVE automatically uploads any events or video as required.
  • Multi-camera support – The Longwatch Video Surveillance software supports different styles and models of cameras to suit your application needs. Legacy analog systems can also be integrated into the Longwatch environment.
  • Multi-network support – IVC’s Longwatch software leads the industry in network flexibility. The LVE can reside on a standard local area network, or placed on proprietary instrumentation networks. This enables you to stretch your infrastructure dollar, keep the system easy to support, and enables video to be transmitted from remote locations using existing, standard hardware.

The LVE software can run on your own computer or can be pre-loaded on one of a number of industrial edge computing devices available from IVC:

Remote Video Engine (RVE)
– 500 GB storage
– 6 camera connections
Micro HD
– 500 GB storage
– 2 camera connections
Micro LPX
– 8 GB storage

– Low Power, Extreme Temperature rating
– 7 W Power; -40° C to 70° C
– 2 camera connections

Guard Tour Mode / Event Clips

Each remote site is individually configured to work within the available bandwidth using a feature called ‘Snapshot Mode’. When enabled, Snapshot Mode communicates with your centralized Video Control Center and transfers still frames of your remote locations. Upon an event or alarm, the Video Engine automatically notifies the Video Control Center and begins sending a full video clip across the network in small bundles. These video clips can be as low as 2.5 KB/frame. Once the video has been fully sent, a notification appears and the video event clip can be played from the Longwatch Viewer interface or on operator screens.

Advanced Features

SCADA/HMI Integration

Longwatch stores video in a variety of formats allowing for complete and open integration across your pre-existing system. These include:

  • HTTP – Use a web browser to view and playback video, control cameras, view alarm information, and for system configuration.
  • OPC Data Access Server – Bidirectional interface with SCADA system. Alarms through Longwatch appear in existing alarm summary screens. Events triggered on the SCADA system can control camera views or control other connected devices, such as lights, doors, or PAGA systems.
  • MODBUS Gateway Server – Bidirectional interface with PLCs and RTUs. Alarms through Longwatch can be transferred directly to industrial control hardware for proper transmission to the SCADA or DCS system. The PLC or RTU can directly control camera views or control other connected devices, such as lights, doors, or PAGA systems.
  • Video Controls – Drop Longwatch video windows directly onto your pre-existing operator screens. View live video and event-driven video clips with integrated Pan-Tilt-Zoom controls.
  • Event Clips – Video clips are stored as open format .avi files. Play, edit, and share your video using commonly available media players on any system with no additional software to install.
  • Email Notification – Events and alarms along with video can be sent directly to operator screen, email addresses, or smart phones for immediate assessment and quick response.

Security Features

Longwatch Video Surveillance comes embedded with several varieties of security features including:

  • Granular Security Control – Using Windows Security, regulate users and cameras access and control.
  • Access Control Manager – The Longwatch system communicates directly to access control devices, HID readers, and key pads. Longwatch is able to read badges and control functions based on user levels, open doors, create camera controlled alarms, and log the event. Each access can be logged onto a video clip, allowing the viewing of archived video of accessed areas by specific users.
