Construction and infrastructure monitoring sometimes expands beyond vibration, tilt, and sound. The traditional response has been to deploy a separate data logger for each new measurement type, which adds hardware, connectivity, and data management overhead to the site. Firms often end up with loggers that have more capacity than the project needs because there was no smaller option available for that sensor type. A modular approach lets firms add one sensor input at a time through equipment they already have deployed.
VEVA III transmits its own vibration, tilt, or sound data to Inzwa Cloud over 4G LTE or WiFi. Its auxiliary port serves as a gateway for compatible connected devices, giving those devices a communication path to Inzwa Cloud without requiring their own cellular connection or separate cloud workflow.
CoreLog collects data from third-party sensors and sends it to Inzwa Cloud through the VEVA III. It attaches to the VEVA III auxiliary port with a locking push connector, sits within about two feet of the unit, and draws power from the VEVA III. No separate power source is needed. Should the sensor need to be positioned further away, a longer cable is available.
CoreLog supports vibrating wire and pulse sensor inputs. Connecting a vibrating wire sensor to a CoreLog does not require tools because the terminals are spring-loaded and the wires push in by hand. Adding a CoreLog to a VEVA III that is already deployed requires only a brief monitoring interruption.
Vibrating wire sensors are standard in geotechnical monitoring. Each contains a tensioned wire whose resonant frequency changes when the measured condition—strain, pressure, load, displacement—changes.
Because the underlying technology is standardized, vibrating wire sensors from any manufacturer are compatible with CoreLog. The sensor manufacturer provides tuning parameters that convert frequency readings into engineering units. Users enter those tuning parameters in Inzwa Cloud. Common types include:
Pulse sensors transmit data as counts. Each event generates one pulse, and the accumulated count over a time period corresponds to the measured quantity. For example, a tipping bucket rain gauge generates one pulse for each fixed increment of precipitation collected (typically 0.2 mm or 0.5 mm).
Because pulse output is a standardized signaling method, pulse sensors from any manufacturer are compatible with CoreLog. Common types include:
When a project requires a measurement type that the monitoring equipment on site does not support, the monitoring team has to bring in a data logger for that measurement. Most data loggers on the market have multiple channels because they are designed to run several sensors at once. If the project only needs one sensor, the rest of that logger’s capacity goes unused.
CoreLog adds one supported sensor input through the VEVA III already on site. There is no separate logger to purchase or manage.
The VEVA III with CoreLog covers measurement types that other vibration monitors cannot cover without separate logging hardware on site. That means firms don’t need to purchase, power, connect, and maintain a standalone data logger every time a project requires a measurement beyond vibration, tilt, or sound. The equipment the firm already owns serves a wider range of projects. Each unit generates more revenue over its operational life.
Summer is when most monitoring firms hit peak project volume. Projects that were delayed earlier in the year come online, new contracts start, and firms that monitor multiple sites need enough equipment, battery capacity, and operational infrastructure to keep up. Peak Season Deployment Challenges When project volume peaks, monitoring firms
Monitoring firms operating on government contracts typically follow a July 1 or October 1 fiscal year. At the start of a new fiscal year, firms make decisions about equipment purchases, calibration services, and budget allocation that determine their operational capacity for the year ahead. How Fiscal Year Budgets Affect Equipment
New York City construction projects will face new compliance requirements starting April 21, 2026. The New York City Department of Environmental Protection (NYCDEP) will require continuous sound monitoring at certain large construction sites performing after-hours work. In practice, this will shift noise enforcement from complaint-driven inspections to continuous data collection.
