Intruder Alarms in Harlow
Commercial premises with staff access, and consistent estate housing stock.

Intruder Alarms in Harlow: what we come across
Commercial alarms in Harlow bring a requirement domestic ones do not: multiple people needing to arm and disarm without sharing one code between everyone. We set up individual users so you can see who set the system and when, and remove someone the day they leave.
The residential side is more straightforward. The estate housing across Church Langley, Newhall and Old Harlow is consistent enough that we can usually scope a system accurately on a short visit, and wireless suits nearly all of it.
Where a unit is unoccupied overnight, pairing the alarm with CCTV matters more than either on its own: the alarm tells you something happened, the cameras tell you what.
Typical jobs here
- Multi-user commercial systems on industrial and business park units
- Wireless domestic systems across the estates
- Alarm and CCTV specified together for unoccupied premises
- App-controlled systems for landlords and managing agents
- Servicing and takeovers on existing commercial panels

Questions
Intruder Alarms in Harlow: common questions
More general questions are answered on our Intruder Alarms page.
- Can different staff have their own alarm codes?
- Yes. Individual users mean the log shows who armed or disarmed the system, and you can remove someone instantly when they leave rather than changing a shared code for everyone.
- Should we have an alarm or CCTV for a commercial unit?
- For an unoccupied premises, both. The alarm gets you a response, the cameras tell you what happened. Specified together in one visit it costs less than doing them separately.
- Do you cover Church Langley and Newhall?
- Yes, along with Old Harlow, Potter Street and the rest of the town.

Testimonials
Trusted across Essex
“I couldn't be happier with the service I received. From start to finish, everything was handled professionally and with great attention to detail. The AJAX alarm system was installed to a very high standard, and everything was explained clearly so I felt confident using it straight away. Mitch was punctual, friendly, knowledgeable, and took real pride in their work. They left everything clean and tidy, and it was obvious they genuinely cared about doing an excellent job rather than rushing through it. If you're looking for someone reliable who provides outstanding workmanship and first-class customer service, I wouldn't hesitate to recommend them.”
