LINETOP DATA LOGGERS
Linetop is the market leader for visitor counters that collect footfall data with data loggers. All of our loggers save visitor data in
tough removeable custom flash memory modules we call memory cubes, as seen in the banner photo above. Data loggers do
involve you (or occasionally us) in fieldwork to change these modules periodically. The used memory cube is downloaded later
with an office PC app and USB reader box. The logger is kept running by fitting a spare cube - along with new batteries when due
- and restarting it with a plug-in control box which has a small LCD screen. Loggers also maintain their grand total since last reset
which can also be read with the control box. Simple projects not requiring detailed data can treat loggers like an electricity meter
where the total units displayed only goes upwards, except that a logger can be reset to zero to begin counting upwards again.
Linetop loggers require three AA-size alkaline batteries which are the kind sold by retail outlets who will also take back used ones.
One set of batteries can last several years but their lifetime may reduce to one year depending on the kind of people or vehicle etc
sensor connected that takes its power from the logger. As data collections are always done more frequently than annually, you
can change the batteries during any routine fieldwork. Loggers are inexpensive and highly cost-effective compared to telemetry
because they are simpler and there are no annual subscriptions or other recurrent costs. Their typical working life is 10 years.
Our original Timelapse logger is still available to buy and is fully supported. This has capacity to store typically 9-12 months of
hourly counts from a single sensor. Our newer TopLog model adds many new features including collecting data from an optional
second sensor or from a sensor that has two outputs to indicate left-right direction of visitor travel. Both data channels are stored
one memory cube. Storage capacity of TopLog is minimum of 1.9 years of two-channel hourly data or 3.8 years of one-channel.
TopLog can optionally record up to 20,000 timestamps (trigger dates and times to the second) instead of hourly or daily totals
when the exact timing and clustering pattern of visitor events is vital to know, such as in surveillance exercises.
Our clients are entitled to expect that our equipment will last a decade without being forced into upgrade or buy-again cycles,
unlike some competitor propositions. Logger-based counters from Linetop are a long-term investment where the capital costs all
arise in the first year, and the future years cost nothing extra. You own the equipment outright and you have full independence.
Memory Cube Reader
Collecting data is done by swapping
the ‘memory cube’ inside the logger for
a spare then restarting it. The used
cube is read later on with an office PC
and USB memory cube reader box, as
shown above. This way of working is
more reliable and easier than carrying
a laptop around the outdoors or using
handheld devices that soon obsolete
given that loggers can last 10+ years.
Loggers are ‘plug-and-play’ devices
that connect to any of our sensors via
a robust socket. They adapt to the
way visitors move: walkers on a open
path go faster than people at a stile.
Being smart devices, loggers take care
of behaviour variability so each visitor
or vehicle gets counted once only.
Logger Control Box
All loggers are set up using a plug-in
Control Box. The process is simple,
like setting a digital wristwatch with the
date and time via push buttons. As the
control box is a fieldworker tool, you
only need one of them regardless of
how many loggers you manage.
The Control Box does not harvest data
from loggers - you swap over the flash
memory cubes to do that and read the
used cubes later on with an office PC.
The Control Box sold for Toplog
loggers has 2 lines of text to make
two-channel results easier to read.
Both Control Box variants work with
both our data logger models and
obtain their power from the logger.
EcoPC Dashboard
EcoPC is our analytical dashboard app
to present joined-up visitor data that
has been collected from various data
loggers over the years. It is simple
enough for anyone familiar with a
word-processor or spreadsheet to use
yet it has powerful features that reveal
patterns and trends within a mass of
unstructured raw data. You will see
integrated results as tables and charts
that can be copy-pasted into office
documents or used as images.
Our database is highly modular which
makes it simple to manage projects
that are geographically dispersed:
where different colleagues at other
locations contribute to a central data
repository via email or fileserver etc.
