Alarm systems designed for Ontario homes and businesses.
Door and window sensors, motion detection, and smart panels tuned to your Ontario property, monitored 24/7 by our own team.
Policed by the Ontario Police Department
Ontario maintains its own police department, so alarm permits, false-alarm response, and dispatch all run through the Ontario Police Department.
Ontario’s enormous logistics and warehouse footprint near Ontario International Airport means many of our installs here are commercial and industrial systems built for large distribution properties, alongside residential work throughout the city.

Designing a security alarm system for Ontario properties
Ontario is built around airport-adjacent logistics, large distribution campuses, and expanding residential, and that shapes how an alarm system should be laid out. A property along Holt Boulevard, Archibald Avenue, and Mission Boulevard has different exposure than one set back on a residential street, and the device plan should reflect that rather than following a generic package. We walk the property first, look at how people actually enter and move through it, and then decide what needs a sensor.
Most of the work we do here is for logistics, air freight, manufacturing, and distribution. The recurring theme is that distribution buildings here are large enough that WiFi and camera coverage need a survey rather than an estimate. Getting that right at the design stage costs nothing extra; discovering it after installation usually means pulling equipment back off the wall.
Building stock matters too. Ontario has large-footprint modern warehouse and older industrial, which affects whether we can run hardwired sensors cleanly or whether wireless devices make more sense in certain areas. We install both, and we will tell you honestly which one suits your building instead of defaulting to whichever is faster for us.
Every system we put in is monitored by our own central station, and long-term agreements convert to month-to-month once the term ends. If you already have a panel from another company, there is a good chance we can take over monitoring on it without replacing hardware.
Since AllTime installs systems throughout the region, is service available in Ontario?
Yes — we regularly design, install, and monitor alarm systems for homes and businesses in Ontario.
How much does a security alarm system cost in Ontario?
Cost depends on property size, number of doors and windows, and whether you choose a wired or wireless setup. Try our free security alarm system cost calculator for a ballpark, then we'll confirm exact pricing with a free on-site consultation in Ontario.
Do you install wired or wireless alarm systems in Ontario?
Both — we install hardwired systems for new construction and larger commercial properties, and wireless systems for retrofits or where running cable isn't practical, and we'll recommend the right fit for your Ontario property.
How quickly can you get to a Ontario property for service?
We dispatch from our Alhambra office and cover Ontario with our own technicians, not subcontractors. For existing monitoring customers we prioritize service calls, and for new installs we can usually schedule a free walkthrough within a few days.
Can you take over monitoring on an alarm system already installed in my Ontario building?
Usually yes. We take over most existing panels without replacing hardware, which keeps switching costs low. If your panel is genuinely at end of life we will say so rather than quietly monitoring equipment that is going to fail.
