FAQ

Does the HPC168 bus passenger counter device support HTTP POST to a custom URL to send count data in real time？What is the data format sent - JSON or hexadecimal string?

The HPC168's RJ45 interface uses the HTTP POST method for uploading and retrieving data. The server response must specify UTF-8 encoding and disable the Accept-Charset response header. All POST field values are hexadecimal strings of the actual data.

Please refer to HPC168 protocol document for details, which contains complete parameter introductions and practical transmission examples for your integration testing.

Why is there a deviation between the data output by HPC015S Wi-Fi infrared counter and the actual on-site passenger flow during operation?

A certain margin of error in passenger counting data from infrared counters is inevitable. Since the device continuously accumulates statistical data, all minor errors will pile up over time. The longer the running duration, the larger the total accumulated error value, and the inaccuracy becomes especially prominent when calculating dwell number of people. Most customers primarily rely on this equipment for comparative trend analysis of passenger flow across identical periods.

If you require precise headcount statistics for people lingering within a designated area, we recommend switching to an AI people counter. AI people counter device identifies actual human figures within the target monitoring zone directly, delivering the highest counting accuracy.

What is the max recommended ESL price tags per gateway?

There is no fixed upper limit on how many ESL labels a single gateway can manage, provided all tags fall within its effective signal coverage.

Each gateway (AP base station) delivers coverage across a circular area with a 20-meter radius. We normally suggest mounting the device on ceilings to avoid signal blockages from shelves, goods and wall structures. Proper high placement helps stabilize wireless transmission and lets the gateway connect with more in-store price tags reliably.

What is the service life of the battery equipped with HPC015S WiFi infrared people counter?

HPC015S WiFi infrared people counter is equipped with the standard 2400mAh rechargeable battery. When the device works 12 hours per day and uploads data once every 10 minutes, the battery can theoretically last for 5 to 6 months. In addition, this device is compatible with USB power supply.

Can we update ESL price tags screens remotely from outside the supermarket? Or must we be connected to the same local network as the base station?

You can remotely update ESL digital price tags away from the supermarket by hosting our software on a cloud server and linking all on-site base stations to the internet.

For in-store local updates instead, install our software on an on-premise PC; the PC simply needs to share the same LAN with connected base stations to finish all screen updates directly.

Does infrared people counter require sufficient lighting to operate properly? Will dim or low-light conditions reduce its counting accuracy?

Infrared people counters can work normally without external lighting. Dim or low-light conditions will not reduce its counting accuracy.

However, sunlight, spotlights and other light sources contain infrared rays, which are likely to interfere with the device and cause counting errors. Turning off indoor lights only eliminates interference from indoor light sources, while interference from outdoor sunlight has a much more obvious impact.

Is the USD 888 software license is a one-time payment for permanent use on one server? Are there any monthly or yearly subscription fees for your ESL management software?

Our software is charged based on single activation for one server only. Once you complete the one-off payment of USD 888 and finish server activation, you gain permanent usage rights without recurring costs.

No monthly or annual subscription charges will apply afterward. All core built-in functions stay available long-term, and you won’t receive regular billing notices for ongoing software service or license maintenance.

How does the software for HPC008 people counting camera operate and allocate devices?

The matching management software for our HPC008 people counting camera is permanently free of charge. It supports two deployment modes: local deployment for on-site device management, or cloud server deployment to centrally control all distributed devices.

After you add devices on our software, you may set a custom name for each unit, and every device will be assigned an exclusive unique data ID automatically.

For system integration access, two options are available:

1. Direct connection with hardware devices: We will supply complete underlying communication protocols for your development.

2. Connection via our management software: Open standard API interfaces are built into the software for seamless third-party docking.

Does the base station need to be plugged into an electrical outlet or is it powered via PoE (Power over Ethernet)?

Our base stations run on power supplied by PoE adapters instead of direct wall outlet connection.

We supply matching PoE adapters and corresponding power cables together with the base station.

This powering solution makes field wiring straightforward and convenient for supermarket installation.

How to integrate the HPC168 bus passenger counter with your system?

Our HPC168 bus passenger counter supports two communication protocols for integration.
1. When the bus has on-board network access, you can connect via RJ45 interface using HTTP protocol (TCP connection).
2. If no network is available, the passenger counter device needs to connect a GPRS module via RS485 interface using RS485 protocol. The RS485 protocol requires the server to actively query, and the queried data is the total number. When reading, the current time is directly recorded. For example, at 10:00, a read shows 10 people entering and 10 people exiting; at 10:05, a read shows 15 people entering and 15 people exiting. This is the data for those 5 minutes: 5 people entering and 5 people exiting. The maximum total number that the device can store in RS485 mode is 999,999. Please refer to the details of our two protocols for further information.

Is the ESL management software interface available in English?

Yes, our ESL software supports multiple preset languages: Simplified Chinese, Traditional Chinese, English, Japanese, German, Spanish, Korean, Ukrainian, Russian, French, Italian, Polish, Czech, Portuguese, Hindi, Persian and Hebrew.

Custom language packs can also be developed per your specific demands if you need extra local languages.

What operations need to be completed after powering on the HPC168 bus passenger counting system?

After power supply connection, just connect the HPC168 passener counter device to a PC and log into the device's web backend for configuration. We recommend mounting the HPC168 bus passener counter at 2.1 meters height for testing.

HPC168 bus passenger counter supports DC 12V to 24V input. Turn off your PC's Wi-Fi and set its wired IP to the 192.168.1.xxx subnet. Connect the passenger counter device to your PC via an Ethernet cable, then open the backend at http://192.168.1.253:8191 on a browser to set the parameters.

If using a router, ensure it uses the 192.168.1.x subnet; reconfigure its network segment if not. You may also skip the router and connect the passenger counter directly to your PC with a matching static IP.
