Behavioural Analysis

Behavioural Analysis uses non intrusive sensor-based to identify, manage and predict unusual behaviour and agitation in prisoners, including those with dementia, or autism, Alzheimer’s wandering, alongside monitoring sedentary behaviour and fall detection.

The solution addresses the individual monitoring needs of prisoners without intruding on personal privacy and decency.

Monitoring prisoner movements, whilst recording changes in the local environment allows alerts to be raised for possible incidents, whilst utilising Artificial Intelligence to analyse the data to identify triggers of the agitation and associated trends.

Behavioural Analysis provides protection and security for all – officers, prisoners and the prison itself.

Safeguard prisoner wellbeing

Tephra’s Behavioural Analysis can help address custodial challenges by providing continuous insight into prisoner behaviour and alerts to sudden changes requiring intervention.  This positively impacts prisoner health and  wellbeing and can alleviate stressful environments. Latest figures show:

Every 5 days

On average, a prisoner in the UK dies by suicide

1 in 5

suicides occur within the person’s first 30 days in custody

1 in 10

suicide cases occur within the first week.

One in every 10

minutes a self harm incident occurs in prison


Meeting the diverse needs of prisoners with dementia or autism can be challenging and prison staff are expected to understand different health conditions and disabilities which can be stressful.

Early periods in custody are often a difficult time for any prisoner, many of whom have multiple risks and vulnerabilities that interfere with their delivery of care. Sleep patterns are affected and can be associated with negative health outcomes including changes in mood and amplifying other symptoms such as agitation, risk of self-harm or suicide.

Providing prison staff and providers working in prisons with alerts for possible incidents enables them to be more equipped to make a positive difference.
