Q: How much does a small business alarm system cost?
The cost of a small business alarm system depends on the size of your property, the level of security required, and the type of equipment installed. Basic packages with intrusion detection and monitoring can be very affordable, while advanced solutions with CCTV, access control, and smart integrations may cost more. We provide clear, upfront quotes with no hidden fees, and financing options are available to help businesses of all sizes. Many clients find that the peace of mind and protection quickly outweigh the investment.
Q: Are your monitoring services ULC certified?
Yes. All of our monitoring is handled through a ULC-listed and certified station, which means it meets the strict standards required in Canada for fire and security alarm monitoring. ULC certification ensures faster response times, reliability, and compliance with insurance requirements. When an alarm is triggered, trained professionals at our station act immediately, contacting you and dispatching emergency services if needed. This certification provides an added layer of assurance for businesses that demand the highest level of protection.
