Mississauga’s lakeside village mixes century-old homes with new mid-rise condos and steady weekend foot traffic along Lakeshore Road, so a video doorbell and exterior cameras keep watch over entrances when the patios and marina are busy.
Lorne Park
One of Mississauga’s most established neighbourhoods, Lorne Park is known for large detached homes on deep, tree-lined lots, where perimeter sensors and well-placed cameras cover the long driveways and side yards that bigger properties create.
