Oshawa Security Systems prefers to use of control panels that require the installation of wires. Wired systems in the opinion of this company outperform wireless counterparts. The installation of a wired system takes longer but the advantages outweigh future problems. Many larger companies promote the 2 door contacts and one motion with a long-term monitoring contract to sign. Oshawa Security promotes complete systems without long-term contracts. This direction in focus is why Oshawa Security is going into its 30th year of business.
