Your property will have the added protection of your alarm system, but what other security issues should you have?

One possible threat might be the people that you allow onto your property. What about the technician who shows up to install, maintain and repair your alarm system? How do you know if they are trustworthy? How well have they been screened? Do they have the proper certifications?

That will depend on who your security company hires as technicians and what type of screening and training they have to go through.

At Alarm Detection Systems, we take the hiring, training, and the certification of our technicians, and all employees, very seriously.

We have a thorough screening process for all new employees. These employees will then go through an onboarding, training, and certification process to ensure that they meet the highest standards. As a result, our skilled and professional technicians are some of the most qualified in the industry.

Therefore, at ADS our employee requirements are:

    • Employees carry photo identification along with their employee number for verification onsite
    • Technicians are bonded and insured
    • All staff undergo extensive background checks including a drug screening and polygraph test
    • Everyone at ADS has a State of Illinois Permanent Employee Registration (PERC) card
