There are a few institutions that certify installers, and although this is good, this by no means guarantees a good installation, but it shows they took the time to be certified. The absence of this certification does not necessarily mean you'll get a bad install, and it can be offset by years of experience, but I'd ask to see credentials if possible. Ask to see some work.

Any reputable shop gives warranties on their labor.
It shows confidence in their installer's work. Ask for follow up maintenance plans. Ask to see what a prospective shop has in mind. Fine tuning and diagnostics of a security system's sensors is almost always required because as the system ages, conditions may change which change the sensitivity and effectiveness of the sensors in your security system.
