“In service, the devices have proved their value time and time again, not least by providing the officers with constant reassurance that, if necessary, they can summon help quickly. That has made their lives much more comfortable and made it a lot easier for them to do their jobs.”
Ian Lockett, Cheshire East Council
“The deciding factors in choosing Peoplesafe came down to the quality of the devices, the competitive pricing and the service as a whole. We would highly recommend the service to others looking for lone worker protection.”
Helen Muddock, Suffolk County Council
“we had one operative who slipped down a staircase outside and the device raised the alarm automatically. He was quite flustered but Peoplesafe contacted him straight away ensuring his welfare which gave him peace of mind.”
Shaun Campbell, Clear-Flow
“We have many links with companies in the local area, so we asked one who they used. They gave us great feedback on Peoplesafe. We looked into them more, saw they met all our needs, trialled their personal safety devices and went from there.”

Hotel Carpark Dispute

A hotel receptionist activated their alarm as there was an incident occurring between two guests in the hotel car park. One guest was punching a car in the car park, while another guest was being verbally abusive to the receptionist. While the incident was occurring the receptionist discreetly activated their alarm, which was received by the Peoplesafe Alarm Controller. The receptionist immediately began talking to the controller as the guest had escalated from shouting to becoming physically aggressive, going inside and removing the fire extinguisher from the hotel lobby to use as a weapon. As the situation was escalating, the alarm controller contacted the police directly, getting the fastest response possible.

The Alarm Controller continued to monitor the situation as the guest took the fire extinguisher outside and began hitting another guest’s car with it, staying online with the receptionist to provide reassurance and kept the emergency services informed of the situation. In the background, the controller also contacted the Hotel Manager, as they were the main escalation contact. The Hotel Manager attended the scene alongside the receptionist to provide assistance. The police arrived within minutes and were then able to take over handling the situation.
