Mobile Response & Keyholding.


What happens when the intruder alarm goes off at 3 o’clock in the morning ?

If you have been lucky, then you may never have had to answer this question yet.  The answer, of course, depends on a number of factors such as:

  •  If it is a domestic property, would you expect a neighbour or family member to get out of bed in the middle of the night and drive to your property to see what has happened?
  • If it is commercial premises, have you stopped to consider the risks associated with having your own employees responding to alarm activations?  Who wants the responsibility (and liability) related to sending their employee into a potentially hazardous situation?

When a security company like ADP acts as a key-holder on your behalf, your staff or neighbour can relax, safe in the knowledge that they will not have to attend the premises in the event of an incident. We are certified by SSAIB and SIA, the leading certification bodies for the security sector.

Our Keyholder / Keyholding Service

We install, and maintain wired and wireless intruder alarms in Southampton, Winchester, Basingstoke, Reading, Fareham, Portsmouth, Chichester, Worthing, and Brighton.
Our key-holder/alarm response service is activated when the alarm monitoring company notifies ADP Security of an alarm activation we send a fully trained security officer to investigate.
When the Security Officer arrives on site, he/she checks the premises to determine the cause of activation. In the event of a false alarm, our Security Officer will check all doors and windows to ensure the building is secure before resetting the alarm. We can also deal with emergency incidents such as broken windows and burst pipes.

Mobile Security Patrols

Our mobile security patrol officers are very effective. In the past, they have caught intruders and handed the individuals straight to the Police. They also act as a powerful intruder deterrent, preventing break-ins and burglaries.

ADP Security’s Mobile Security Patrols Are…

  • Reliable, providing an effective deterrent that gives you peace of mind when you are absent.
  • Ideal for remote industrial sites, high value properties, educational campuses, construction sites and garage forecourts.
  • Affordable

Our fully trained mobile security guards will patrol your site at regular intervals through the day or night. Their first check will ensure that all windows and doors are locked, and no intruders are present. Subsequent checks will ensure there are no disturbances. Our service can include building lock-up and unlock.

Customer sites covered by a mobile patrol will receive branded signage from ADP Security to show that your premises are protected, increasing the deterrent value of our patrols
