Frequently Asked Questions
1. What makes an IR beam system better than a PIR motion sensor for door entry alerts?
IR beam systems detect a specific line of sight being broken, which eliminates false alerts caused by ambient movement or heat sources—common issues with PIR sensors.
2. Can Campad Electronics’ buzzer be integrated with existing security or POS systems?
Yes. The wireless receiver includes optional trigger outputs that can be linked to alarm panels, access control units or POS software for unified reporting.
3. How does the traffic counting feature work?
Each time the infrared beam is interrupted, the receiver logs a count. The data can be accessed via a web interface or exported for analysis, giving businesses accurate footfall metrics.
4. Are there any maintenance requirements for the wireless doorway buzzers?
The system is designed for low maintenance. The battery backup should be checked annually and the prismatic reflector should be kept clean of dust or debris.
5. What is the typical installation time for a Campad Electronics system?
A single transmitter/receiver pair can be installed in under 30 minutes, including mounting the reflector and configuring the receiver’s volume.
6. Is the system suitable for outdoor doorways?
While the standard unit is rated for indoor use, Campad Electronics offers weather‑sealed accessories that allow the transmitter and receiver to be protected for semi‑outdoor installations.
7. How does the wireless range compare to other solutions on the market?
The standard 10 m range covers most storefronts. For larger sites, optional radio modules extend communication up to 280 m, surpassing many basic PIR chimes.
8. Can the audible alert volume be adjusted?
Yes. The receiver features a multi‑step volume control, allowing businesses to set the chime level appropriate for quiet offices or bustling retail floors.
9. Are there any subscription fees for using the traffic counting data?
No. All counting functionality is built into the hardware and accessed locally; there are no recurring cloud fees.
10. What power options are available for the transmitter and receiver?
Both units can be powered via mains with a plug‑in adapter and they include a rechargeable battery backup that activates automatically during a power loss.
11. Is the system compatible with smart home hubs?
Through optional Zigbee or Wi‑Fi bridge modules, the receiver can transmit alerts to smart hubs, enabling mobile notifications and automation.
12. How does Campad Electronics ensure the system remains secure against wireless interference?
The radio link uses frequency‑hopping spread spectrum (FHSS) technology, which minimizes the risk of signal interception or interference from nearby Wi‑Fi networks.
By focusing on accuracy, expandability and actionable data, Campad Electronics delivers the best door entry alert for business needs across a wide range of commercial environments.
