Smart Security Products for Newmarket Homes
Smart Doorbell Camera for Newmarket Homes
A smart doorbell camera shows you who is at the door of your Newmarket home — whether you’re upstairs, at work or out at Upper Canada Mall. It records every visitor and delivery, flags motion at the porch and ties into your alarm system, so a package left at the door doesn’t have to sit there unwatched.
Smart Security Cameras for Newmarket
Smart security cameras give you clear footage of the places you can’t watch — the driveway, the side gate, a backyard that opens onto a trail or ravine. Each camera integrates with your alarm system and 24/7 monitoring, records key moments and sends alerts to your phone the second something moves.
Smart Lock Protection for Newmarket Homes
A smart lock ends the hidden-key habit. Let the kids in after school, give a contractor a one-time code, and confirm from your phone that the front door locked behind them. It works inside your Grand Alarms system at home and doubles as simple access control for a Newmarket business.
All in One Security System for Newmarket Homes
One smart panel runs everything — alarm, cameras, locks, thermostat and 24/7 monitoring — with one app for the whole family. It’s a complete security setup for a Newmarket home or business without the complexity of juggling separate devices and subscriptions.
Professional Newmarket Security Installation
Our own trained technicians install and service every system we sell in Newmarket — most homes are done in a single visit, including app setup and a walkthrough. And because we service what we install, follow-up support comes from the same local team, for the life of the system.
Security for Newmarket Neighbourhoods
From estate lots in Stonehaven–Wyndham to century storefronts on Main Street South, every Newmarket neighbourhood has its own security profile. Grand Alarms technicians work across all of them — here’s how we match the system to the street.
Grand Alarms Ltd. | 9000 Keele Street Suite 12 Vaughan Ontario L4K 0B3
Home Security and Alarm Systems in Stonehaven–Wyndham
Stonehaven–Wyndham’s executive homes near the Magna Centre sit on some of Newmarket’s largest lots, which means longer sightlines and more entry points. We cover them with outdoor cameras, glass-break sensors and full-perimeter monitoring built for bigger properties.
Smart Home Security in Glenway Estates
With ongoing infill construction around the former Glenway golf lands, west-end residents see more unfamiliar vehicles and trades traffic than most of Newmarket. Video doorbells and driveway cameras give Glenway Estates homeowners a clear record of who comes and goes.
Security Systems and Alarm Monitoring in Summerhill Estates
Summerhill Estates is commuter country — busy families heading down Yonge Street or to the GO station each morning. Smart locks and app-based arming let parents confirm the kids are home from school and the doors are locked, from anywhere.
Woodland Hill
Newmarket’s newest subdivision near Yonge Street and Davis Drive is full of recent builds, many pre-wired by the builder. We integrate what’s already in the walls and complete it with monitored sensors, cameras and smart-home control — usually in a single visit.
Armitage
Armitage’s mature crescents off Yonge Street are quiet, established and popular with long-time owners who travel. Monitored intrusion protection plus freeze and water sensors keep an empty house safe through a winter getaway.
Bristol-London
Close to the Yonge–Davis corridor and Upper Canada Mall, Bristol-London mixes townhomes, semis and rentals where doors and windows sit close to busy sidewalks. Compact wireless systems with door, window and motion coverage fit these homes without renovation.
Gorham–College Manor
East of Main Street around Pickering College and Southlake Regional Health Centre, Gorham–College Manor blends century homes with newer streets. Shift workers and hospital staff especially value 24/7 monitoring that doesn’t depend on a neighbour noticing something wrong.
Huron Heights–Leslie Valley
Backing onto the East Holland River valley and its trail network, many Huron Heights–Leslie Valley yards are open to the ravine. Outdoor cameras and motion-activated alerts cover the back fence line most houses can’t see from inside.
Historic Downtown / Main Street South
Newmarket’s Main Street Heritage Conservation District is home to century storefronts with apartments above. Wireless sensors protect heritage plaster and trim, and after-hours monitoring covers shops, restaurants and offices when the street empties out.
Newmarket Business Park (Harry Walker Parkway)
Warehouses, contractors and light industry along Harry Walker Parkway need more than a door contact. We build commercial systems with cameras, monitored intrusion and fire protection, and access control that tracks who entered the shop and when.
24/7 Home and Business Monitoring in Newmarket
Our own trained technicians install and service every system we sell in Newmarket — most homes are done in a single visit, including app setup and a walkthrough. And because we service what we install, follow-up support comes from the same local team, for the life of the system.

Olivia T., Newmarket
I wanted a smart home setup that allowed full control from my phone. Grand Alarms built a system that fits our home perfectly. Their monitoring service gives us peace of mind when we are away.
Newmarket Security System FAQ
How does a home alarm system help Newmarket families?
A monitored alarm system protects your doors, windows and interior spaces, and alerts our ULC-listed monitoring station the moment something trips. For Newmarket families that means faster response than a phone notification you might miss — and a record of exactly what happened and when.
Does your company install systems for Newmarket businesses?
Yes. Our company installs smart alarm systems for both home and business properties. Many Newmarket businesses rely on cameras, sensors and monitoring to maintain a secure environment.
Are smart home devices easy to control?
Smart devices work through a central panel and a mobile app. Homeowners in Newmarket use these controls to manage alarm settings, view cameras and adjust security preferences.
How long does installation take?
Most home or business installations in Newmarket take a few hours. The technician sets up sensors, connects the alarm system and ensures the smart controls work correctly.
Do you provide same day service in Newmarket?
Our company offers prompt service for Newmarket homeowners. Response times depend on scheduling, but we work to support every home and every business quickly.
Can I expand the system later?
Yes. Alarm systems in Newmarket can grow as your home or business needs change. You can add cameras, smart locks or additional sensors at any time.
Do you offer support for moving within Newmarket?
We assist customers who move to another Newmarket home. We help transfer systems, reinstall smart devices and update monitoring details.
Are professional monitoring services required?
Monitoring is optional but strongly recommended. Newmarket homeowners gain faster response and better security with real monitoring instead of app only alerts.
Do your systems work during power outages?
Yes. The alarm system includes backup power. This keeps home and business security active in Newmarket during power interruptions.
How much does a home alarm system cost in Newmarket?
Grand Alarms packages for Newmarket homes range from $32.99 to $59.99 per month, with $0 upfront options and a 3-year price lock. Every plan includes 24/7 ULC-listed monitoring, and installation is handled by our own technicians.
Which Newmarket neighbourhoods do you serve?
We install and monitor alarm systems across all of Newmarket, including Stonehaven–Wyndham, Glenway Estates, Summerhill Estates, Woodland Hill, Armitage, Bristol-London, Gorham–College Manor, Huron Heights–Leslie Valley, Central Newmarket and the historic Main Street district, plus the Newmarket Business Park on Harry Walker Parkway.
Can you install a security system in an older home near Main Street?
Yes. Our wireless sensors and cameras install cleanly in Newmarket’s older and heritage homes without cutting into original plaster, trim or brick. The system communicates over a cellular connection, so no new wiring is required.
I’m in a new build in Woodland Hill — can you work with what’s already there?
In most cases, yes. Many newer Newmarket homes come pre-wired or with builder-installed panels. Our technicians assess what is usable, integrate it where it makes sense and add the sensors, cameras or smart locks your family actually needs.
Will a monitored alarm system lower my home insurance in Newmarket?
Many insurers offer a discount for homes with professionally monitored, ULC-listed alarm systems. Ask your insurance provider what documentation they need — we can supply a monitoring certificate for your Newmarket property.
