CCTV installation at Edmonton High School

“Protech Solutions were very professional in carrying out our CCTV installation last week.  They were very knowledgeable and advised us on the best solution for us.  We are very happy with their work and would not hesitate to use them for any future requirements we might have.”
(Nick Aristodimu, Edmonton High School)

CCTV installation at Edmonton High School

We were asked in by the school to help them to replace their existing analogue CCTV system.


After an initial site survey, we were able to advise them on the best and most cost-effective solution.


Since then, we have been sporadically swapping out the school’s old analogue CCTV for new Lilin CCTV over IP.


On this occasion, we installed 4 replacement cameras.

Installing the CCTV was very straight forward but installing cabling routes into the 100 year old building was the challenge.  


Our engineers were climbing through dusty, cob-web ridden lost voids to find the best cable routes but the result was a flawless system, working to full capacity.
