I HAVE HAD A LOT OF PROBLEMS WITH THE EQUIPMENT I HAVE PURCHASED FROM THIS COMPANY. THEY WILL NOT STAND BEHIND THE EQUIPMENT THAT HAS FAILED. I HAVE SENT EQUIPMENT BACK TO THEM FOR SERVICE, AND THE EQUIPMENT IS SENT BACK AFTER BEING REPAIRED NON OPERATIONAL. iT IS VERY HARD TO GET A RETURN PHONE CALL ABOUT PROBLEMS. MY SECURITY COMPANY WILL NO LONGER USE THIS COMPANY, AND I RECOMMEND NOT USING THIS COMPANY.
