The MotionWatch 8 is the next generation of medical-grade actigraphy watch for the monitoring of sleep, circadian rhythm and physical activity. Trusted by clinical and research professionals around the world, the MotionWatch 8 is one of the leading actigraphy solutions for convenient long-term behavioural monitoring with high patient compliance.
The MotionWatch 8 provides objective outcome measures for research and clinical applications and has been deployed in large scale pharmaceutical clinical trials. The comfortable and robust ergonomic design is one of the smallest and lightest available making suitable for deployment in paediatric populations or the elderly. Manufactured in our established ISO13485:2016 facility and having multiple regulatory clearances, the MotionWatch has a proven track record for quality and reliability.
CamNtech are pioneers of actigraphy with over 25 years of experience since inventing the first Actiwatch devices. Actigraphy is a well-established method for monitoring of sleep quality and circadian stability. The MotionWatch has been used in cutting edge research for many years and our Research Library provides a comprehensive list of scientific publications citing its use. Our informative training videos provide a great introduction to the set-up and operation of the system.
NEW! Core Body Temperature
The MotionWare software can now import the core body temperature data from the BodyCap e-Celsius® system.
e-Celsius® is a miniaturized electronic ingestible capsule that transmits core temperature data continuously.
For e-Celsius, please Contact BodyCap directly.
Light-weight and waterproof
Fast direct USB transfer
No reader required
Ambient Light Sensor
Event marker button
User replaceable battery
Records for up to three months
Software includes NPCRA
Raw data export options
Optional PLMS Analysis software
Windows & Mac OS compatible
The MotionWare Software is a companion software suite that allows for the set-up, download and analysis of data captured with the MotionWatch 8 or MotionWatch Rugged. Accelerometer data captured with the PRO-Diary may also be analysed with the MotionWare software.
Available for both Windows and Mac OS, the MotionWare software provides device management tools such as battery monitoring in addition to data management tools including flexible report generation and bulk text export.
Motionware also provides a suite of analysis functions for Sleep, Circadian Rhythm, Physical Activity and Ambient light data.

Cloud Data Ready
The MotionWatch 8 seamlessly integrates with our Cloud Data Manager (CDM) to provide secure patient data collection and management. Individual patient actigraphy data are uploaded to the cloud and synchronised with the central data repository under control of the CRO or sponsor. A range of security features including 256bit encryption ensures data remains safe.

Sleep and Chronobiology
The Sleep Analysis functions within the MotionWare software allows the user to access and analyse data on a full range of sleep and circadian parameters. Building upon the sucess of our legacy Actiwatch system, the software provides advanced tools for determining sleep efficiency, sleep fragmentation, sleep latency and many more actigraphy derived sleep parameters.
The key advantage of the MotionWatch for sleep monitoring is the unobtrusive nature of the device leading to a true reflection of the subjects’ behaviour in their own home environment.
Actigraphy is also an ideal tool for examining circadian stability and chronobiology as it is possible to obtain long term recordings with high patient compliance.
The Motionwatch incorporates an in-built light sensor to monitor light exposure and the MotionWare software incorporates Non-Parametric Circadian Rhythm Analysis (NPCRA) for quantifying circadian stability. This method has been found to be superior to cosinor analysis when applied to actigraphy data.

Physical Activity Monitoring
The Physical Activity Analysis function of the MotionWare Software can be used to record daytime physical activity and report on sedentary behaviour and levels of Moderate to Vigorous Physical Activity (MVPA). The MotionWare software incorporates in-built tools for the classification, quantification and reporting of MVPA from actigraphy data.
This data can be used for a wide variety of applications e.g. as an indicator of a particular lifestyle, to monitor the effects on mobility of a medical condition or efficacy of its treatment, or to identify irregular activity patterns for assesment of sleep quality.
