Guards perform a variety of different job roles in a retail environment, especially in the busier areas of London. It is impossible to rely on your staff to provide impeccable service whilst keeping an eye on things.
Manned retail security guards are also capable of performing minor assistance roles such as greeting people in the store, offering assistance or giving directions to a specific aisle.
This form of security allows a single team of guards to easily manoeuvre between locations ensuring each one is secure.
Whilst mobile patrols are not able to secure a single area in the same way a guard could, they are capable of keeping an eye on a large amount of locations in one area. This works well for franchises looking to keep multiple retail shops safe.
