Security alarms designed around your site. your home. your business. your farm.
Security alarm installation for homes, shops, warehouses and commercial sites in Whanganui, the Manawatu and across New Zealand. We walk your property, find the weak spots and build a system that fits, not a one-size-fits-all package.
It starts with a walk around your property.
Everyone wants the same thing from an alarm: to feel protected. How you get there depends on the building, the people in it and what you are worried about.
Site inspection
We walk the site, check entry points and listen to what actually worries you.
The right panel
Wired or wireless, one keypad or twenty zones. We match the system to the site.
Tidy install
Clean cabling, labelled zones and a system tested end to end before we leave.
Trained and supported
We show your staff or family how to use it, and we are here when you need us.
The right sensor in the right place.
A good alarm is a mix of devices, each chosen for the room it protects. We plan them around how someone would actually get in.
Motion sensors
Pick up movement in a room or hallway, with pet-friendly options so the dog does not set it off.
Door and window contacts
Trigger the moment a door or window opens, before anyone is inside.
Glass break sensors
Listen for breaking glass, so a smashed window is caught straight away.
Sirens and strobes
Loud inside to drive intruders out, and visible outside so neighbours and patrols know where to look.
Keypads and app control
Arm and disarm with a code, a tag or your phone, with separate codes for each user.
Panic buttons
A fixed or portable button to call for help when you need it, day or night.
Homes
Keep your family and property safe, with an alarm you can arm and check from your phone.
Retail and service stations
Protect stock and staff with duress buttons, monitored zones and fog cannons where they are needed.
Commercial and industrial
Keep plant and equipment protected after hours, with areas, schedules and user codes for every team.
An alarm nobody hears is just noise.
Connect your alarm to 24/7 monitoring and a break-in gets a real response: keyholders called, patrol sent, and every step logged.
Two ways to build an alarm. We will tell you which suits.
Both are secure and both can be monitored 24/7. The right choice depends on the building, how big the site is and what else the alarm needs to connect to.
Wired alarms
Sensors cabled back to a control panel. The most robust option, and the best fit when an alarm needs to work with access control.
Wireless alarms
Encrypted wireless sensors with no cables through your walls. Fast to install, tidy and run from a phone app.
Neat on the wall, neater in the cabinet.
“After having numerous problems with previous security systems we changed to Sectek. No problem has been too big and gone unsolved.”
Keep it, fix it, or upgrade it.
Takeovers and upgrades
We work on all systems, any brand. If your alarm was put in by someone else, we check what you have, keep what still works and upgrade only what needs it.
Alarm health checks
A flat battery or a dead sensor usually goes unnoticed until the night it matters. A regular service covers:
Security alarm questions, answered.
Can you take over an alarm another company installed?
Yes. We work on all systems, any brand. We will check what you have, fix any faults and tell you honestly whether it is worth keeping.
Wired or wireless?
Both have their place. Wired suits new builds and big commercial sites. Wireless, like AJAX, suits finished homes and shops where running cable is hard.
Can I control it from my phone?
Most modern systems we install can be armed, disarmed and checked from an app. We set it up and show you how it works.
Do I need monitoring?
It is not compulsory, but without it an alarm relies on someone hearing it. Monitoring means every activation gets a response, day or night.
How much does a security alarm cost?
It depends on the size of the property and the number of sensors you need. We visit for free, walk the property with you and give you a clear written quote.
Will my pets set it off?
Not if it is set up properly. We use pet-friendly motion sensors and place them so a cat or dog can move around freely while the alarm is set.
What happens in a power cut?
Every alarm we install has a backup battery, so it keeps protecting you and reporting to the monitoring centre while the power is out.

New install, a system nobody looks after any more, or a second opinion. Tell us a bit about the property and we will be in touch, usually the same day.
