Actiwatch Guide to Getting Started 7.2 (July 2009) Contents
The Actiwatch is a compact and lightweight electronic device
that measures and records physical movement. Worn on the
non-dominant wrist for sleep or activity analysis and on the
feet for Periodic Limb Movements in Sleep (PLMS) analysis,
the Actiwatch can be worn for long periods of time by
subjects of all ages and any health status.
Depending on the model selected, the Actiwatch is available
as a fully waterproof unit with a battery life of up to 8 years
continuous usage. Models of Actiwatch are available that
record the following:
•
Physical activity (can be used to measure sleep quality
with the Actiwatch Sleep Software)
•
PLMS (when mounted on the feet and used with the
relevant software)
•
Light (if a compatible Actiwatch model is selected)
•
Activity & subjective patient input (Actiwatch Score –
detailed in a separate manual)
•
Tremor (Tremorwatch - detailed in a separate manual)
The Actiwatch collects movement data which is stored in the
non volatile memory and is then transferred to the PC using
CamNtech’s proprietary telemetric reader/interface. The
movement data can then be analysed using the relevant
software package. Details on the models of Actiwatch and
analysis software packages available can be found in Section
1.3.2 of the Guide to Getting Started. Further details on how
the Actiwatch system works can be found in Section 1.4 of
the Guide to Getting Started.
The Actiwatch system consists of 3 components:
•
Actiwatch
•
Actiwatch Reader
•
Actiwatch Software

Actiwatch System
1.2 Components of the
Actiwatch System
Actiwatch Guide to Getting Started 7.2 (July 2009) Contents
The Actiwatch range consists of the following models:
•
Actiwatch AW7
The Actiwatch AW7 was launched in 2007 and extended
the functionality and practicality of the Actiwatch range.
With a battery life of 8 years continuous use, activity
marker button and recording time of up to 180 days with a
1 minute epoch, it is also the most highly specified
Actiwatch in the range. The AW7 has been pressure
tested to 6 Bar and is suitable to be worn whilst swimming.
•
Actiwatch AW4
The Actiwatch AW4 is the predecessor to the Actiwatch
AW7. It has been used extensively by researchers,
clinicians and in clinical trials. It offers a recording time of
up to 45 days with a 1 minute epoch.
•
Actiwatch Mini
The Actiwatch Mini is designed for applications where
weight or size is important. It is ideal for paediatric use.
Weighing only 7.5 grams it is the lightest actigraph on the
market. It can be supplied for either wrist mounting or
neck mounting.
•
Actiwatch Light
The Actiwatch Light allows the monitoring of ambient light
levels as well as the measurement of activity. It is ideal for
circadian rhythm studies or any application that requires
light monitoring. The light sensor is integral to the watch
and is provided in place of the marker button.

•ActiLight
(External light sensor for use with the Actiwatch
Mini/AW4/AW7)
The ActiLight is a separate light sensor for use with an
Actiwatch. Light data is recorded for up to 45 days (at a 1
minute epoch) and can then be combined with activity
data. This unit is housed in a similar case to the Actiwatch
Mini so is extremely light. It has the advantage that the unit
can be worn either attached to the clothing or on a neck
chain so can be kept clear of clothing or bedding when
used for recording night time light levels.
A table showing the specifications of each model is shown on the
following below. Full technical specifications of all models are
contained in the technical appendix of the Actiwatch Manual.
(This table contains complete specification details for standard
types of Actiwatch. All other models2have separate user manuals)

1.
Recording times shown are for a 1 minute epoch. A
shorter epoch will result in a shorter recording time.
2.
The other Actiwatch models that are available are the
Actiwatch Score, Actiwatch PLMS Software &
Tremorwatch. The functionality of these units is covered
in separate manuals.
3.
The battery life for the Actiwatch AW7 is 8 years of
continuous use.
4.
The weight quoted for the Actiwatch AW7 is without a
strap. 2 traps (a nylon strap and a plastic strap) are
provided as standard with each unit. For full information
on the types of strap and mounting options available,
please contact CamNtech.
Actiwatch Guide to Getting Started 7.2 (July 2009) Contents
There have been three versions of the Actiwatch reader
produced by CamNtech:
•
Early models had a white face and a single red LED.
These units are not compatible with later Actiwatch
models such as the AW7, Mini and ActiLight. Please
contact CamNtech for details of replacement costs
•
Later readers have a blue face and a bi-coloured
red/green LED. These units can only be connected to the
host PC by a serial cable. When using one of these units,
it is necessary to use a USB- Serial converter if a USB
port is to be used. For further details please see Section
2.9 of the Guide to Getting Started. These models are
compatible with all Actiwatch models.
•
The Actiwatch USB reader provides direct connectivity
with the host PC via a USB port and will provide faster
download of the Actiwatch AW7. This model has a
sloping front panel with two status LED’s (red and green).
The following software analysis packages are available for use
with the Actiwatch range:
•
Activity Analysis Software
•
Activity and Sleep Analysis Software
•
PLMS Analysis Software (See separate PLMS Software
manual)
•
Activity and Score Analysis Software (See separate Score
manual)
Full details of each software package are contained in the
Actiwatch User Manual. For advice about which software
package is best suited to a particular application, please
contact CamNtech.

1.3.5 Compatibility tables
Actiwatch Guide to Getting Started 7.2 (July 2009) Contents
Please note that certain models of Actiwatch, although
compatible with series 5 software will only work with a specific
version or later. Specifically this includes the new Actiwatch Mini
and the ActiLight. For full details please contact CamNtech.
Actiwatch activity is measured in counts. This is a term used to
denote the amplitude of the signal produced by the
accelerometer in the Actiwatch. The number of counts is
proportional to the intensity of the movement.
The accelerometer in the watch checks or samples the
amplitude of the movement thirty two times per second and it
captures the highest amplitude in that second.
This represents the peak intensity of the movement in that
second. The peak intensity values are summed into a user
selectable epoch (epoch range between 2 seconds and 15
minutes depending on the model of Actiwatch used). Activity
values can be viewed in counts per epoch in the software or
exported and viewed in Microsoft Excel. Full technical details on
the operation of the Actiwatch can be found in the appendices
of the Actiwatch User Manual.

The Actiwatch system is supplied with a CD ROM containing all
of the components of the software package. The following are
the minimum requirements of a host PC in order to be able to
install the Actiwatch software:
•
IBM compatible 300Mhz +
•
Windows 2000, NT, XP or Vista operating system
•
100 MB hard disk space
•
USB or serial port (If a USB port is used then a USB –
Serial converter will be required if a blue faced reader is
being used – please see Section 2.9 of the Guide to
Getting Started
•
A CD-ROM drive or equivalent
•
Graphics (800 x 600 pixels minimum)
•
Printer (if hard copy output is required)

for details of connection/use for this hardware.
To install the software, place the supplied CD ROM into the
CD/DVD drive on the host PC. The user then needs to select the
correct installation package depending on which operating
system is being used on the host PC. A different installer is used
for Windows XP/2000/Vista from that used for Windows 98/ME.
Please note that, following Microsoft’s decision to stop
supporting earlier versions of Windows, CamNtech cannot
guarantee that Actiwatch software is compatible with Windows
95 or 98.
