Video Turnstile People Counter Specifications
At its simplest, the Video Turnstile system comprises an overhead CCTV camera connected to a Logging Video Turnstile Unit which detects and counts people. Counts are verifiable so you can see the accuracy of the system for yourself. Up to 120 entrances can be monitored by one system. Counts can be sent to a PC in a back office, or remotely over a modem to head office.

Logging Video Turnstile Unit (LVT)
- Number of logged epochs: 900
- Minimum epoch length: 10 secs
- Maximum epoch length: 8 hours
- Maximum count: 65535 - then rolls over through 0
- Inputs: 32 normally allocated in pairs for UP screen and DOWN screen counts
- Communications options:
RS232 9600 baud, no parity, 1 stop bit, 8 data bits
RS485 9600 baud, 4 wire
Ethernet - TCP/IP fixed IP address
WiFi - 802.11b
- With RS485, up to 30 logging units can be installed on a single cable - giving monitoring of up to 960 doorways (RS485 output kit needed).
Display Meter
- Display meter shows either the total visitor count or current occupancy.
- Total visitor count uses the IN counts from each Video Turnstile unit.
- Occupancy uses the IN and OUT counts from each Video Turnstile unit
- Shows count from up to 4 Video Turnstile units.
- Maintains count whilst power is off.
- Count reset to 0 by a button press.
- Count reset can be disabled.
Dwell Meter
- The Dwell Meter lets you see how long customers spend in an area and how often an area was visited.
- Tracks up to 4 people at one time.
- Produces a histogram of the time that people spend in the counting zone with 64 programmable size bins.
- The Dwell Meter comprises a modified VT Unit with its associated Logger.
- The Dwell Meter VT should be at address 0.
- The histogram bin width is set by the TON parameter.
- The programmed value is in units of 0.1 seconds.
- You can read the current bin states and so show an updating histogram by reading the counter channels 0 to 15.
Camera
- Black and white, or colour, closed-circuit television camera (CCTV).
- Mounted into ceiling tiles so camera is flush with the ceiling.
- Option for dome camera instead.
- Pin connections - Pin 1: Video, Pin 2: 0 V, Pin 3: 0 V, Pin 4: +12 V.
- Normally supplied with a standard 3.6 mm lens and are suitable for installation between 2 and 3 meters above the floor. For a higher camera a different lens is required to restore the video picture to the parameters used by the detector.
- The camera should be between 0.5 and 1 metre from the entrance or exit.
Windows Software
- VT Setup software lets you fully configure the VT units.
- Windmill data collection software continually logs and displays counts on a PC.
- Alternatively, VT Collect software collects count data, for example, once a day.
- The software saves data in a text file, compatible with other Windows programs like spreadsheets or databases.
- Low-cost analysis software (VisitorTrends Lite) available.
