Officers will conduct security checks on all areas of your property. Security signage can also be provided.

On arrival, we will conduct a security check of the property, liaise with the police, reset the alarm, or take necessary action that is required to ensure your premises are safe and secure.

Residential Key Holding & Intruder Alarm Response Service Operations

You can arrange for your alarm monitoring station or your intruder alarm speech dialler to contact us if there is an intruder alert. When we receive the alarm activation alert, our trained and dedicated staff log the call, and despatch the closest security patrol vehicle to attend your property and contact you directly.
When our security arrives at your property, they will assess the situation by conducting an external patrol of your property and take whatever necessary action is required, keeping you informed of the situation. If it is a false alarm our security officer will take the necessary actions to re-set your intruder alarm system.
Our security patrol officer will fully assess the situation and leave the property secured on completion. All providing peace of mind for the client.
