A single sensor tracks usage pattern, activities, occupancy, traffic flow and helps predict trends.

Commercial cleaning is a complicated set of tasks. With smart restroom technology, IoT technologies have only scratched the surface. Introducing ZanWave, a radar-based solution that not only transforms the smart restroom space through efficient smart restroom technology but also provides a more comprehensive solution, true predictive cleaning technology. This privacy-aware solution can locate people in a space, understand usage, and predict cleaning needs not only in restrooms, but also in conference rooms, common areas, and other areas.

Zanwave Zan-In Traffic Monitoring

ZAN-In Traffic Monitoring is a people counting sensor that employs cutting-edge technology, including a groundbreaking radar system that provides highly accurate position data. The sensor detects people walking into and out of predefined areas while maintaining privacy – no camera is used – and operating in low-light environments. The sensor can be installed above the false ceiling, and its output is in a point cloud format, containing the X, Y, and Z coordinates of the identified objects. Zan-in traffic monitoring can also be used as a toilet cleanliness monitoring system by counting the number of people who use the toilet at any given time.

Zanwave Open Area Traffic Monitoring

Zanwave Open Area Traffic uses the same sensor as Zan-In traffic but the deployment is different. While Zan-In traffic focuses on entry and exit within the field of view, Open Area Traffic provides a lot more data by combining the traffic flow data with data gathered from all other sources to show usage pattern, usage statistics, peak usage, non-peak usage, predicted traffic, overcrowding, social distancing, cleaning requirements, user satisfaction, etc. to optimize space management decisions.

All data traffic between sensors and gateways is encrypted using 128-bit AES encryption even though we do not collect private/sensitive data through any of our solutions.

Occupancy Monitoring System

In the post-COVID world, there has been a dramatic shift in the workplace. Work-from-home (WFH) is the new normal. Technology solutions have made Work from Home (WFH) as effective as Work from Office (WFO), if not more so. As a result, many businesses have adopted WFH as a permanent arrangement, with employees required to visit the office only when necessary. One of the key trends in Office Space in the US is "Hybrid workplace"- where you have permanent office space and "flexible office space"- where employees with flexible working space work from home a few days a week and come into the office a few days. When they come into work, they may not have a permanent space, but use one of the available flexible spaces. This concept is called the "hoteling" concept. This is also becoming the new norm. For this concept, occupancy monitoring and managing space becomes extremely critical.

Corporate real estate is expensive, accounting for a sizable portion of most companies' cost base. There is now an opportunity to save money by consolidating office space and freeing up underutilized or unused space. These types of decisions must be data-driven, which is where occupancy monitoring systems come in. Apart from efficient space utilization, occupancy monitoring systems also aid in other applications, such as better energy management - heating, ventilation, and air-conditioning (HVAC) through temperature sensors, gas, lighting, and smoke detectors, air quality monitoring through optical particle counter sensors, optimal janitorial staff utilization, and improved safety standards - through occupancy patterns and usage statistics. It is possible to obtain accurate occupancy data using Internet of Things (IoT)-based sensors without jeopardizing user privacy.

We provide a full range of occupancy monitoring solutions and space utilization technology solutions including Door Sensors, Room Occupancy Sensors, Beacon Scanners, RF sensors for in/out traffic monitoring, and open area traffic monitoring in cubicles, office rooms, conference rooms, phone booths, lobby areas, gymnasiums, toilets/restrooms in office buildings. In addition to office buildings, our solutions are used in airports, hospitals, sports complexes, and shopping malls, where we can combine data from our sensors with external data such as flight arrivals and departures to predict cleaning requirements. Depending on the purpose, they are also known as monitoring systems in general or, more specifically, restroom monitoring systems or occupancy monitoring solutions.

Door Sensors

The Zan Door Sensor counts the number of times the door is opened and closed in janitorial applications. Through our smart restroom technology, the algorithm calculates overall traffic flow using data from the rest of our sensors in the restroom. The sensor is a magnetic contact switch with one half mounted on the door and the other on the door frame. The sensor connects to a device that uses Bluetooth Low Energy space utilization technology to communicate with a gateway.

Room Occupancy Sensors

The ZAN room occupancy sensor detects the number of people walking in and out of the door using Time of Flight (ToF) technology. The people walking in and out will be counted by the IR sensing direction device. The sensor is typically installed in the ceiling and has a detection range of up to 3 meters. Using Bluetooth Low Energy technology, the sensor continuously monitors traffic and communicates with a gateway.

Frequently Asked Questions

What is occupancy monitoring?

Occupancy monitoring is a combination of target object detection, target object counting, movement tracking, and activity tracking. Target object in our case refers to people and therefore occupancy monitoring in our context is about people detection, people counting, people movement, and the activity that they are involved in (to a small extent).

How do monitoring systems track room occupancy?

Using various sensors, room occupancy can be tracked in a variety of ways. The tracking method is determined by the ultimate goal. Simple door sensors can determine whether or not a room was occupied in a given interval by tracking the opening and closing of the door. Time of Flight sensors, such as Zan's ROS, can count the number of people entering and exiting the room and thus determine the real-time occupancy of the room by placing them at each entrance and exit. Finally, sensors like ZanWave can track the "usage" of the room by not only tracking real-time occupancy, but also the actual usage of all objects in the room, such as which desks/chairs are occupied.

What is space utilisation or occupancy data?

Space utilization refers to the usage of each type of area (cubicle, office room, conference room, lounge area, parking area, etc.). It can provide data on how often each area is used, when it is used, for how long it is used, and how many people are there vis-a-vis full capacity at any point of time in the case of common areas.

What is the significance of space utilization?

Data on space utilization aids in the identification of opportunities for optimization, the avoidance of waste, the maintenance of social distance, and the improvement of hygiene standards. Tracking space utilization is becoming increasingly important as many organizations transition to dynamic seating arrangements.

What is an occupancy monitoring system or occupancy monitoring solution?

The occupancy monitoring system is a system that uses occupancy monitoring sensors deployed at different parts of an area being monitored to detect people count, people movement, duration, and other statistical information. The sensors send real-time data to a central management dashboard. The dashboard is cloud-based and can be accessed at any time, from any connected device. It can also be configured to send instant alerts to the building manager if the specific activity takes place (e.g. flooding in the toilet) or if a planned activity does not take place (e.g. janitor does not perform cleaning at the scheduled time or the number of people in an area crosses the COVID threshold).

What is a restroom monitoring system?

A restroom monitoring system/toilet cleanliness monitoring system can be an occupancy monitoring system for a restroom, it can be a monitoring system for tracking the level of consumables or cleanliness of the restroom or a space utilization technology solution designed for restrooms called the smart restroom technology.
