Site security for Derry building sites
Coast Data Security hires rapidly deployable CCTV towers, solar powered options and temporary intruder alarms to construction sites in Derry, on the west bank and east bank of the Foyle and out towards Strabane. Because the North West is a distance from our Castlewellan base, Derry hires work best as planned, longer-term jobs rather than a short one-off visit.
Where the sites are
Sites across Derry, on both banks of the Foyle.
Derry sits either side of the River Foyle, with the walled city and Cityside on the west bank and the Waterside on the east, linked by the Peace Bridge and the Craigavon Bridge. Building work ranges from city centre and riverside redevelopment to business park units at Campsie and Springtown, and out towards Strabane the sites are more often rural, with farm buildings and one-off houses on quiet roads. Whatever the site, the distance from our base means a tower or an alarm is usually booked for a run of weeks rather than a day or two.
That is not a reason to avoid the North West, it is the reason a hire needs planning. A CCTV tower or a temporary alarm is a set-and-leave job once it is commissioned: the camera watches the compound and raises a remote alert if someone crosses into it, so it does not need a daily visit to earn its keep. That suits a Derry site well, where a planned trip to install and a planned trip to collect make more sense than trying to service equipment every few days from ninety-five miles away.
What we plan for
A hire built around the distance, done honestly.
We are upfront that Derry and the wider North West sit at the edge of where we cover comfortably for a quick callout. What works well is a tower or alarm hired for a defined period, whether that is a groundworks phase, a full build programme or a business park fit-out, so the trip is planned once for delivery and once for collection or redeployment rather than repeated short visits.
If a Derry site only needs a few days of cover, we will say so rather than take the booking anyway. Where the job is a genuine multi-week or multi-month build, a CCTV tower with remote monitoring and a temporary alarm on the cabins is exactly the kind of planned work that makes the distance worthwhile for both sides.

Why us in Derry
Honest about the distance, committed to the job.
Coast Data Security is based in Castlewellan, County Down and covers Northern Ireland, including Derry and the North West, for construction site security that is planned rather than reactive. Every installer is fully qualified and carries comprehensive public liability insurance, and every Derry hire starts with a proper site survey and a clear conversation about timescale, so the trip is planned around a job that genuinely needs weeks of cover, not a same-day dash across the country.
How a Derry hire is planned
From enquiry to a tower on site
- 1
Call or send the form
Tell us the site address in Derry, roughly how long the job will run and whether power reaches the compound. Longer, planned jobs are what we build a North West trip around.
- 2
Free site survey
We visit to check the compound, the gate, access on either bank of the Foyle if relevant, and whether a mains tower, a solar tower or an alarm suits the site.
- 3
Delivery and commissioning
The tower or alarm is delivered, positioned, tested and handed over, with the detection, alerts and remote viewing explained before we head back to County Down.
- 4
Remote cover through the build
The tower runs and alerts remotely for the length of the hire, with a planned visit to reposition or collect once the phase or the job is finished.
Typical Derry sites
What usually suits which kind of site
A survey confirms it, but these are the site types that make sense for a planned Derry hire.
| Site type | Usual risk | Setup that suits it |
|---|---|---|
| City centre or riverside redevelopment | Materials and tools behind a hoarding in a public area | Mains-fed tower with remote monitoring for the build programme |
| Business park unit at Campsie or Springtown | Plant and stock on an open compound | Mains-fed tower covering the gate and yard |
| Rural house or farm building towards Strabane | No power on site, quiet road, little passing footfall | Solar tower with detection covering the compound |
| Multi-phase housing development | Materials on plots across a long build programme | Tower redeployed at planned visits as phases finish |
| Short refurbishment or fit-out | A few days or weeks of exposure only | Best suited to a temporary alarm rather than a tower trip |

Construction site security in Derry, answered.
The questions we get before planning a hire for Derry and the North West.
How much does site security hire cost in Derry?
Every hire is priced after a site survey, because the cost depends on how many towers or alarms the site needs and how long the job runs. You get a written quote with no obligation before anything is booked.
Do you actually cover Derry, it is a long way from your base?
Yes, but we are upfront that Derry sits around ninety-five road miles from our Castlewellan base. We take on Derry jobs that are planned for weeks or months of hire, where one trip to install and one to collect make sense, rather than short one-off callouts.
Do you cover both sides of the Foyle and out towards Strabane?
Yes. We hire towers and alarms to sites on the Cityside and the Waterside, business park units at Campsie and Springtown, and rural sites out towards Strabane, as part of a planned North West visit.
There is no power at my Derry site, can you still fit a tower?
Yes. Our towers are available with a solar power option, so the camera and detection work without a cable run to the compound, which suits many rural and early-phase sites.
My job only needs a few days of cover, can you still help?
For a short job, a single trip to the North West is harder to justify and we will say so honestly. Site security hire works best for us in Derry when the job runs for at least a few weeks.
Do you offer weekly or monthly hire for Derry sites?
Yes. Derry hires are usually booked by the month given the distance involved, though a longer weekly arrangement can work for a job with a clear end date. Either way there is no long-term contract.
How do I know if someone gets onto the site while you are not there?
Detection on the tower raises a remote alert as soon as someone crosses into the compound, so you and we both know immediately rather than waiting for the next planned visit.
We already have a fence around the compound, is a tower still worth it?
A fence slows someone down, it does not tell you if they got past it. A mast camera with remote monitoring adds the part a fence cannot do, which matters even more on a site we are not driving past every day.
Are your installers qualified and insured?
Yes. All installers are fully qualified and carry comprehensive public liability insurance, on a Derry hire the same as on any job closer to our base.
What happens once the Derry site is finished?
We collect the equipment on a planned visit, and if the finished building needs permanent CCTV, alarms or access control we can quote that separately using the same team.
