Scott B

Outstanding Service & Pricing

“I can not recommend this company highly enough! Really speedy and friendly communication, very fair pricing, wonderful care and attention during whole process including installation by the lovely Connor….i have dealt with numerous alarm and CCTV companies over the last 20 years and Mark the MD and his team are a dream to deal with and better than any others i have ever dealt with.”
Andrew D

Great customer service

“Really great customer service from Mark who went through our alarm system requirements followed up by engineer Connor who installed the detectors and control box and went through the user set up and menu options.

I would definitely recommend.”
Julie B

CCTV Installation

Tahir A

Outstanding Company So glad we found them

“Our initial interactions with Trisec were warm and technically oriented. Mark consistently provided precise responses, instilling confidence in their capabilities. The alignment between Trisec’s approach and our values drove our decision to choose them as our service provider…”
Doreen M

A very professional company

“A very good experience from the outset. Mark explained the system well and Connor was very efficient during the installation.”
Ann H

Top quality service from start to finish

“Top quality service from start to finish.
Super quick response from Mark to my enquiry and then my new cctv system was installed within 2 weeks by Connor, who was personable, helpful and informative about our new system.”
Alan H

Great service & products

“Top company
Installed new alarm system to a large house in a day and cleaned up and took the rubbish away.
Excellent service”
Ray J

thank you to Mark and team

“They installed four camera recording system. The end results were excellent. When we wanted a change to the final system, they make the change and did not charge any extra! Cannot fault their professionalism. Wouldn’t hesitate to recommend them”
Dave A

Dream team

“Needed an alarm and cctv system after several breaking in the area. Rang three companies, one just wanted to sell me anything, the next was just like a car salesman, plenty of banter but no idea!! Mark was fantastic!!”
Richard H

If only everything was this easy

“Trisec have been looking after my alarm systems for many years now. Naturally, the Covid lockdown was the time selected by my system to throw a ‘dicky fit’ and reward me with a call from Central Station at 1.00am. I contacted Trisec and the response was a visit from Mark at a speed that would be envied by Road Runner and Wile E Coyote.”
Tim E

Excellent in every way

“Today we had a Home CCTV system fitted by Mark & Connor from Trisec. From the initial site assessment and quotation to the installation being carried out today, everything has been perfect. Both guys treated my house like it was their own, taking great care to carry out a seamless and tidy installation without unsightly wiring….they even went as far as hoovering up afterwards!”
