Kia ora, I’m Jason Whyte
When you call OneSecurity, you get me. I answer the phone, walk your site, do the install and look after it afterwards.
I’ve spent more than 30 years designing, installing and servicing CCTV, alarms, access control and 24/7 monitoring. OneSecurity is owner-operated and based in Masterton, looking after homes, farms and businesses across the whole Wellington region: Wellington, the Hutt Valley, Porirua, Kāpiti and the Wairarapa.

What you can expect
- One point of contact, from first visit to aftercare
- A written plan and quote showing camera positions, alarm zones and options
- Neat, labelled, tested installs, cleaned up before I leave
- Straight advice: I’ll service or reuse good existing gear rather than replace it
- A reply to every enquiry within one working day
“Jason was excellent: very prompt in responding to our initial inquiry, always kept us well informed on progress, turned up exactly when he was expected.” — Kathie and Steve, Masterton
