BENS Video Activated Alarm Combines Edge Analytics With Professional Alarm Monitoring.
BENS Video Activated Alarm – BENS Video Activated Alarm (VAA) is a monitoring architecture designed to connect video edge analytics with professional operator monitoring, using event-triggered video clips rather than continuous video streams.
According to BENS, traditional motion detection continues to create challenges for central monitoring stations through high false alarm rates, operational inefficiency and alarm fatigue. BENS Video Activated Alarm is designed to address these issues by providing verified response capability, with edge devices detecting events and securely transmitting short video clip payloads to BENS operators for assessment.
VAA operates as an event-driven monitoring pipeline. Rather than continuously streaming video, compatible edge devices identify events locally and send the resulting clips to the VAA platform.
Generating high-confidence alarms takes robust on-board AI analytics. Processing of incoming streams must be capable of accurately classifying object types, including people and vehicles, and situations such as intrusion, crowds, loitering and line crossing. The analytics also need to filter common environmental triggers including foliage movement, weather changes, small animals and shadows.
Operationally, once a processed high confidence alarm event is received, the video clip is presented directly to a BENS operator for visual verification. This allows the operator to assess the event and make a dispatch decision. A VAA app and web portal provide an instantaneous feed of video and actions.
The architecture is designed to integrate with existing deployments without requiring proprietary gateway retrofits or alterations. For cloud-based systems, VAA provides out-of-the-box support for major cloud relay architectures including Verkada, NX Witness and Hik Pro Connect.
Meanwhile for standard IP cameras and encoders, VAA can handle video files directly through SFTP, which BENS identifies as the preferred transport method, as well as FTPS or FTP.
The system also incorporates health monitoring to distinguish a quiet scene from an offline camera. VAA uses an open health-check protocol, with a heartbeat mechanism based on periodic file transfers. These can be lightweight .txt files sent at intervals ranging from 10 minutes to 12 hours, providing an indication that the connected system remains operational.
BENS also specifies edge capabilities to optimise VAA integration. Event clips should be 10 to 20 seconds long in standard MP4 format and include a 2-second pre-alarm buffer. Edge devices should use NTP-synchronised UTC clocks, with event timestamps embedded directly into the MP4 creation metadata. This allows operators to distinguish live events from delayed transmissions from an earlier incident.
Store-and-forward capability provides additional resilience during network outages. BENS recommends on-board edge storage, such as an SD card, with automated retry protocols and configurable overflow policies. These can be configured to preserve the oldest undelivered clips when network connectivity is unavailable.
The VAA architecture is intended to reduce the volume of unnecessary alarms reaching monitoring operators while retaining video evidence of detected events. BENS’ architecture diagram contrasts conventional continuous live video monitoring with event-triggered recorded clips, with VAA providing verified events for operator assessment and response.
The approach places the initial detection and classification workload at the edge, while retaining professional operator verification and response at the monitoring centre. This reduces the requirement to continuously transmit video while providing operators with event-specific footage when an alarm is generated.
BENS is an alarm monitoring provider with a deep history, as well as a video monitoring pioneer, and BENS Video Activated Alarm is well worth investigating.
