New Outdoor USB People Counter: Integrated Casing and Up to 4-Year Battery Life
EvolvePlus has introduced a new Outdoor USB People Counter that combines bi-directional infrared counting, onboard data storage and a robust outdoor enclosure in one compact, battery-powered solution.
Designed for locations where mains power and network connectivity may be unavailable or expensive to install, the new model is ideal for public toilets, park entrances, walking trails, footpaths, outdoor attractions and industrial sites. Its integrated casing simplifies installation, while an estimated battery life of up to four years reduces routine maintenance at remote locations.

What is new about the Outdoor USB People Counter?
The previous outdoor USB model placed the people-counting sensors inside separate protective enclosures and used two AA alkaline batteries, with an estimated battery life of approximately one year.
The new model introduces two important improvements:
- Integrated outdoor casing: the electronics and protective enclosure are combined in two robust units - a transmitter and receiver - for a neater, more straightforward installation.
- Long-life lithium battery: a 3.6V D-cell lithium thionyl chloride battery provides an estimated operating life of up to four years, significantly reducing the frequency of battery replacement.
The enclosure is designed for IP65-equivalent protection and an operating temperature range from -20°C to +60°C, making the counter suitable for demanding outdoor and industrial environments.
Accurate bi-directional footfall counting
The transmitter and receiver are installed opposite each other across an entrance or path. The transmitter creates an active horizontal infrared beam, and the counter records movement when a person passes through and interrupts that beam.
Bi-directional detection provides separate In and Out counts, giving organisations a clearer view of visitor flows than a simple total count. The system supports entrances up to six metres wide and requires no mains power, network cabling or local internet connection.
This makes the Outdoor USB People Counter a practical entry-level option for monitoring foot traffic at sites such as:
- public toilets and amenities blocks
- park entrances and nature reserves
- walking tracks and footpaths
- outdoor events and festivals
- visitor attractions and recreation facilities
- dusty or damp industrial locations
- other remote sites without convenient power or communications infrastructure
Collect data using a USB memory stick
The people counter stores up to 40 days of minute-by-minute data in its internal memory. To collect the data, connect a USB memory stick to the counter, then upload the captured file to the IMMotion Cloud platform from a computer.
There is no need to visit the site at the end of every day. One collection can retrieve the stored readings, ready for analysis across hourly, daily, weekly and monthly intervals.
Turn visitor counts into useful insights
The IMMotion Cloud Dashboard converts the collected data into practical footfall insights. Organisations can use these reports to identify peak periods, compare usage over time and make more informed decisions about staffing, opening hours, maintenance and cleaning schedules.
The Free edition supports USB data imports, basic Excel exports and 90 days of history. The Premium edition adds:
- multiple logins & security permissions
- additional dashboard visualisations
- expanded Excel export options
- more than three years of data history
- status alerts
- groups for organising counters across multiple locations
- ongoing troubleshooting support
For organisations that need more advanced reporting or centralised analysis across a broader sensor fleet, the EvolvePlus Enterprise Cloud Dashboard is also available as an option.

Frequently asked questions
Does the Outdoor USB People Counter need mains power or internet access?
No. The counter is battery powered and stores data internally. Data is collected with a USB memory stick, so the installed sensor does not require mains power, network cabling or internet access.
Can it count people entering and leaving separately?
Yes. The active infrared sensor provides bi-directional counting, with separate In and Out totals.
How often does the battery need to be replaced?
The supplied 3.6V D-cell lithium thionyl chloride battery has an estimated life of up to four years. Actual battery life can vary with operating conditions and usage.
How much data can the counter store?
Its internal memory stores up to 40 days of minute-by-minute count data. Regular USB collection is recommended so that the oldest readings are not overwritten.
Is the counter waterproof?
The enclosure is designed for IP65-equivalent protection. EvolvePlus can advise on installation position and suitability for the conditions at a specific site.
How wide can the entrance or path be?
The transmitter and receiver can operate across an entrance up to six metres wide, subject to correct positioning and alignment.
