Bob Tansley -Seaford
Outstanding installation service for our new CCTV system and recent installation of a new Intruder Alarm system saving us 40% on a previous quotation. I would thoroughly recommend Hallmark Security.

Gerri Ori – Seaford
A very reliable and reasonably price service.

I have recently had an alarm system installed by hallmark Security. The service I received was first class and I would recommend this company to any of my friends, family and business associates.

Hallmark are professional from the first contact to the installation and the ongoing support – great service, great value and great results.
