Wireless Security Products for your Home and Business


Pre-Lock Security Services has been installing some form of Line Security Back up for almost 35 years from the days when DVAC line security was the best you could get.    Our beliefs right from the start is offering security that works is our most important goal.  We understood from the start that we could not rely 100% on telephone line transmission for our security and always offered alternatives that provided our customers the best possible security services available.  

Unlike most security providers we offer different backup protection for different security systems we sell.  We match the line security technology to the alarm panel we are installing and the features that the panel transmission is capable of providing.    With our team of professionals you can count on our technology to provide your family with backup protection when you need it most.

Over the Last 5 years we started putting in GSM Radios.  We offer them for all our systems, in fact we don't need to connect to the phone lines anymore to offer you the best services ever.  This is great news for cell phone only homes or VoIP customers. 

Our customers are extremely pleased with our wireless technology solutions that provide the highest level of secured transmission available today.  With Real-time 24/7 Cellular backup you will know what happens the minute it actually happens.  Every home protected by cellular backup monitoring is constantly monitored in real time from our professionally staffed central monitoring station right here in York Region.  If an alarm is activated by your system, our central station will know about it instantly and so will you when you subscribe to our new e-alert service.

If you are considering a security system without line security consider this. 
Without it you don't have security it's that simple.

Call us today to see which technology will work best for your system.
