**Special promotion on now: free alarm installation + 15% off the first year of monitoring** (valid for new installations only) By strategically locating devices designed to detect intrusion, Safetech's acquired a unique ability to successfully protect both people and property. By blending together different security technologies and procedures we achieve the highest security standard possible with the lowest “rate of loss” among our clients in the industry. Only by taking a comprehensive integrated security approach to the needs of our clients can the best results be achieved. For instance, statistically adding an alarm will reduce a chance of a ‘break and enter’ by 10x when compared with a home that has no alarm system. However, if you combine one or more surveillance tools together, such as an alarm system combined with video surveillance cameras, your chance of a ‘break and enter’ is reduced by 40x when compared with an unprotected property. Furthermore, even if you do end up being a victim of a ‘break and enter’ the amount of property stolen is 50% less than it would be if the premise only had an alarm system. Compare this to a property that has little or no protection (no alarm or video cameras) the savings are even greater, with a total 80% reduction in loss of property value. Therefore, security surveillance tools work even better when used in tandem to prevent property loss and are a very effective way of deterring and reducing crime. Good Protection Starts with Good Design Safetech loss prevention advisors are trained to ensure clients receive proper security coverage using the significant arsenal of security tools and techniques they have at their disposal. An advisor will begin first by having a detailed discussion with our potential clients to determine their specific application and security needs. Once an advisor is satisfied that they have an understanding of the clients needs a security solution will be recommended. There is absolutely ‘no obligation’ to follow any recommendation given and there is no charge for our security evaluation. Good protection may start with good design but it can only be maintained with good monitoring and management procedures.Most people think that a 24 hour monitoring station exists solely to respond to emergency signals. However, equally important is the need to respond to no signals when one is expected, or to trouble signals coming from the control panel. A trouble condition may arise when a client’s alarm panel fails to send its scheduled weekly test signal to the monitoring station, or, if it sends a signal indicating that the power has failed or the back up battery is low. “How quickly a security company deciphers and responds to these conditions is a true measure of the quality of their service”.
