IoT Entry/Exit Vehicle Counter | Count-In, Count-Out Occupancy for Smart Parking

The IoT Entry/Exit Vehicle Counter is the fastest, lowest-cost way to make a smart parking system work on day one. Instead of instrumenting hundreds of individual bays, it counts every vehicle that enters and exits at each ramp, gate, or lane, then does the simple, reliable math that drivers actually care about: spaces free = total capacity minus vehicles inside.

Installed on a DIN rail inside a small cabinet near a controlled entry or exit point, the counter works as a universal directional counter controller. It reads the entry/exit sensor that best fits your site, whether that is an IR break-beam pair, a radar or microwave module, or the output of an external inductive loop detector, and uses simple direction logic to tell the difference between a vehicle coming in and a vehicle going out. The sensors themselves are sold separately as optional kits, so one product covers every site type instead of forcing you into a fixed sensing method. Every event is time-stamped, counted, and pushed upstream in real time, so your guidance signs, mobile app, and dashboard always show an accurate live count per lot and per level.

Because a single counter can cover a whole ramp or gate, coverage that would take dozens of in-bay sensors is handled by one device. That makes it the ideal first product to deploy in any retrofit or new-build parking project: quick to install, easy to justify, and immediately useful. Pair it with the Parking Guidance Gateway to aggregate multiple entrances and drive multiple signs, and with the Smart Parking Flip-Dot Guidance Signage to display the result.

Built on IoTize’s industrial IoT platform, the counter connects locally to the gateway over Wi-Fi, Ethernet, or RS485, speaks HTTP, MQTT, and Modbus TCP, integrates with SCADA, MES, and cloud dashboards, and supports on-prem, private cloud, or IoTize SaaS deployment. Old lot or new garage, it gives every entrance new intelligence.

Key Features

• Count-In / Count-Out Detection – Directional counting distinguishes vehicles entering from vehicles exiting for a true live occupancy figure.
• Live “Spaces Free” Data – Streams occupancy and remaining-capacity counts per lot and per level to signs, apps, and dashboards.
• One Device Per Ramp or Gate – Covers an entire entry point without wiring a sensor into every bay, cutting install cost and time dramatically.
• Universal Sensor Support – One controller reads IR break-beam pairs, radar/microwave modules, and external inductive loop detectors, so a single product suits any ramp width, traffic speed, or site layout. Sensors sold separately as optional kits.
• Rich Sensor Interfaces – 4x opto-isolated digital inputs (NPN/PNP), 1x RS485 (Modbus RTU) for serial sensors, and 2x relay/digital outputs for a local FULL indicator or barrier trigger. Wide-range 9-36V DC sensor power terminals on board.
• Flow-Rate and Peak Tracking – Logs vehicles per hour and peak entry/exit times to support capacity planning and staffing.
• Threshold Alerts – Configurable alerts for “lot full”, “near capacity”, or abnormal flow, sent to operators in real time.
• Edge Counting Logic – Counts and validates events locally, so brief network dropouts never lose a vehicle; data auto-syncs on reconnect.
• Connectivity – Talks locally to the Parking Guidance Gateway over Wi-Fi, Ethernet, or RS485, using HTTP, MQTT, and Modbus TCP. No cellular modem on the counter; the gateway carries the site uplink.
• Solar / Battery Option – Solar panel and rechargeable battery add-on for gates with no grid power or expensive cabling.
• Industrial Build – DIN-rail industrial enclosure, the same rugged family as IoTize’s Enterprise devices, mounted in a control or field cabinet near the entry/exit. For outdoor or exposed gates, house it in an IP65 field cabinet. Operating temperature -20 to +60 degrees C.

Technical Specifications

Applications in Detail

• Multi-Level Garages – One counter per ramp gives an accurate free-space count for every level, feeding level-by-level guidance signs.
• Open-Air and Surface Lots – Count at the single controlled entry/exit to publish live “spaces free” at the street.
• Shopping Malls and Retail – Track peak inflow and outflow to manage congestion during sales and events.
• Corporate and Campus Parking – Separate employee and visitor entrances, each with its own live occupancy.
• Hospitals and Airports – High-turnover sites where drivers must be routed to free zones quickly to cut circling and emissions.
• Event and Stadium Parking – Temporary gates with the solar option, no cabling or grid connection required.
