Alarm monitoring and security system installation prices at Jadtec Security Services are among the very lowest in the industry. Monitoring is done locally at the company's Orange, California headquarters. Rates start at $13.95 per month on a quarterly basis, plus a one-time $65 connection fee. If you need to cancel your service, Jadtec will even refund the unused portion of the prepaid fees with no penalties. Jadtec can monitor 99 percent of existing systems with no adjustments needed. New system installations start as low as $425. There are no equipment leases or rentals -- Jadtec customers own their systems. And Jadtec does not install proprietary equipment or use lockout codes that would prevent alarm monitoring by other companies.
