Features
- Capture time-stamped events: Send contact closures to March Networks network video recorders (NVRs) to trigger time-stamped event recording.
- Expand monitoring and control: Add I/O to connect more sensors, contact inputs, and relay-controlled equipment as site requirements grow.
- Support equipment uptime: Remotely reboot cameras and network devices, or configure automatic rebooting when equipment stops responding.
- Extend security capabilities: Monitor door and gate status and control access peripherals, lighting, and alarms.
- Automate locally: Configure devices through a browser and run control logic directly on the hardware without cloud dependence.

ControlByWeb® designs and manufactures industrial I/O controllers that connect physical equipment and sensors to security and monitoring systems. March Networks uses ControlByWeb devices to provide contact closures to its NVRs, helping capture time-stamped events for review and investigation. Beyond event recording, ControlByWeb offers expandable monitoring and control capabilities for remote and automatic rebooting, access control peripherals, environmental monitoring, and security automation. With browser-based configuration and local control logic, integrators can build on the existing installation to improve site visibility, support equipment uptime, and reduce unnecessary service visits.
Frequently Asked Questions
What is ControlByWeb, and how does it integrate with March Networks?
ControlByWeb designs and manufactures industrial I/O controllers that connect physical sensors and equipment to security and monitoring systems. When integrated with March Networks NVRs, ControlByWeb devices send contact closures that trigger time-stamped event recording. This helps security teams capture and review events associated with connected devices, supporting more efficient monitoring and investigations.
How does ControlByWeb enable event recording on March Networks NVRs?
ControlByWeb controllers send contact closure signals to March Networks NVRs. These signals trigger time-stamped event recording, allowing security teams to associate physical events with recorded video. This capability supports event review and investigations by helping operators identify when activity occurred at connected sensors or equipment.
Can ControlByWeb help reduce equipment downtime in video surveillance systems?
Yes. ControlByWeb controllers support remote and automatic rebooting of connected cameras and network devices. Integrators can configure controllers to restart equipment when it becomes unresponsive, helping restore normal operation without requiring an immediate on-site visit. These capabilities can support equipment uptime and reduce unnecessary service visits.
What security and monitoring applications can ControlByWeb support?
ControlByWeb controllers support applications beyond event recording, including door and gate status monitoring, access control peripherals, lighting, alarms, and environmental sensors. Their expandable I/O capabilities allow integrators to connect additional devices as site requirements evolve, extending security monitoring and automation through the existing installation.
Does ControlByWeb require cloud connectivity for automation?
No. ControlByWeb controllers support browser-based configuration and can execute control logic locally on the hardware without relying on cloud connectivity. This allows integrators to configure automated responses and equipment controls directly on the device, supporting security monitoring and operational continuity at locations where cloud-dependent automation may not be preferred.
