Frequently Asked Questions: Security Cameras in Thornhill
How much does it cost to install security cameras in Thornhill?
It depends on the number of cameras, the resolution (4MP, 5MP or 4K), cable lengths and the property. Large homes in Uplands or Bayview Glen often need six to eight cameras. Every Blaze Alarms quote is written and upfront, and includes installation, hidden cabling, NVR setup, app setup and a walkthrough, with no monthly fees.
Do I need a permit to install security cameras on my Thornhill home?
No. Homeowners don’t need a municipal permit to install exterior cameras on their own house, as long as the cameras cover your own property. Avoid aiming cameras into a neighbour’s windows or yard. For a business, we’ll tell you at the assessment if anything else applies.
Are you really based in Thornhill?
Yes. Our office is at 30 North Park Rd, Thornhill, ON L4J 0G6. Most of Thornhill is a few minutes away for assessments, installs and service calls.
Do you install cameras for Thornhill businesses?
Yes. We install CCTV for shops, clinics, restaurants and offices along Yonge Street, Bathurst Street, Highway 7 and in Commerce Valley, with entrance, cash and parking coverage and remote viewing for managers.
Will my footage be useful to York Regional Police?
Clear footage gives police the best chance to identify people and vehicles. Our 8MP (4K) cameras capture faces and licence plates in sharp detail, and you can export clips from the app in minutes. No camera can guarantee an arrest, but good footage makes a real difference.
Will security cameras hold up through Thornhill winters?
Yes. Our cameras are IP67 weatherproof and rated down to -30°C. Hard-wired cameras have no batteries to die in the cold.
