Information gathering tags, our backend system and front end user interface

The operational freedom of self-powered, self-sustaining monitoring tags

Imagine how much simpler (and less costly) life could be if you didn’t have to:
  • Monitor the power levels of your devices to know which one is going to die next
  • Suffer information starvation from devices with dead batteries
  • Bring assets back to base just for battery recharging or
  • Send maintenance personnel out into the field to recharge batteries
Passive Eye delivers the kind of information about your field assets that helps you build a more efficient and productive company.

Alerts, Alarms and Advisories


Mobile Assets: If the tag is mounted on an asset designed to move, it will send on-start and on-stop advisories to calculate asset utilisation. The start/stop time buffers can be adjusted to control sensitivity and the asset’s location is sent when the asset comes to a stop.

Static Assets: Nothing is ever perfectly still and when mounted on an asset that shouldn’t move (such as a major piece of construction or farming equipment that’s laid up for a season), movement and vibration is continuously monitored and if the parameters are breached, an alarm is sent repeatedly until acknowledged or cancelled.


Indoor: (under development) Passive Eye will shortly be able to provide small, self-powered and self-sustaining tags used to report the location of such things as sub-assemblies, pallets and the cages used to assemble orders inside factories and warehouses. Granularity depends on the installation of beacons.

Outdoor: The tag is an event-driven system and operates independently of any system provided by the asset. It sends location information along with the on-stop date and time to provide continuing asset or supply chain visibility.


Spot: A geo-fence with a user-defined radius can be positioned around the asset’s location to obtain an alert when it crosses the boundary or perhaps at the entrance to a customer’s location to receive a notice when it arrives or leaves a specific location.

Area: A boundary can be drawn around a construction or mining site for example so that movement inside the area is ignored but an alert can be sent if an asset moves beyond the boundary of the prescribed area.

Route: Passive Eye’s AI assisted logic will monitor activity and send an alert if an asset deviates from a habitually travelled route or comes to a stop that is too long for existing weather or traffic conditions.

Asset Health and Physical Conditions

Shock Loads and Excessive Tilt: Containers for example, are handled by a variety of 3rd parties on the journey from a supplier to their customer. Passive Eye’s always-on tags monitor for shock loads and excessive tilt and will send a ‘damage event’ report with the time, date and location if limits are breached, sufficient to cause damage. The damage event report helps shippers determine what company was handling the container or transport trailer at the time and thereby mitigate their liability.

Environmental Conditions: Passive Eye supports a broad range of sensors which can be positioned inside a container, trailer or transport vehicle and programmed to report when such things as temperature, humidity and CO reach their upper or lower limits, changes in light levels which may indicate a breach of security and a variety of other sensors.

Easy Provisioning and Data Security

Provisioning App: To make provisioning as easy as possible, Passive Eye provides a ‘Provisioning App’ (Android only) to bond the ID of the tag and the ID of the asset in the database in 5 very easy steps.

1) When arriving at the asset’s location, open the app and confirm that the map accurately displays your (and the tag’s) current position.
2) If so, scan the QR code on the tag;
3) Then remove the protective covering from the high tack pads and press the tag firmly on to a high, horizontal, clean and dry surface of the asset;
4) Next, scan, photo or enter a text description of the asset and designate whether the asset is fixed or mobile;
5) Click the ‘Submit’ button to bond the tag’s ID and your asset’s ID in the database

If an error has been made or if a tag is to be re-positioned, the Provisioning App can be used to repeat the process and the new data will overwrite the previously submitted data.

Platform and User Interface

Passive Eye is a system that gathers the data, sends it to our backend cloud platform via a wireless link and presents the requested data on the user’s interface and dashboard.

Machine learning (ML) is used to learn what ‘normal’ operations look like for each asset and with experience, unusual or harsh handling which could shorten an asset’s useful life or increase its maintenance costs, could be identified and an advisory notice sent to the operating company. Monitoring the way equipment is handled would also be useful to companies providing equipment finance or leasing as it may affect the residual value of an asset.

Artificial intelligence (AI) is used to automatically add spot, area and route geo-fencing to give operators early notice if a vehicle spends too long at a specific location, if equipment leaves a construction or mining site for example, if a vehicle deviates from an established route or if a timing parameter has been exceeded when taking weather and traffic into consideration.

Data Security

All communication emanates from the tag. It will not respond to an incoming call so the tag cannot be spoofed.

All data including location, is coded for added security and all data is hardware encrypted before it’s transmitted over a wireless link to our cloud server.

Security is Paramount
Our cloud architecture is designed from the ground up to provide the highest possible levels of security including 3 levels of firewalls and dedicated servers to isolate and protect each major function.

User Interface
Current and Historical Locations: When logging on, the map displays the current or last reported location of each tagged asset. Double click on a selected asset and use the slide bar to designate the start and end dates to a display the asset’s reported locations during the selected period.

Download Your Data
The user interface provides the designated administrator with the controls to download all of the monitored data from our database in the .CSV file format.

Delete Your Data
After downloading the data, the administrator can use the Delete button to delete the downloaded data from the Passive Eye database.

Add Passive Viewers
The administrator has read/write authority to download, delete existing data and to make changes to various operational parameters. The company’s employees can register as ‘passive viewers’ for full navigation and viewing rights.
