Services
Welcome to S.E.M. Security Systems your full service Electronic Security Company serving New York and New Jersey for all your Home and Business needs. We are experts in designing, installing and Monitoring, Burglar Alarms, Security Systems, Certified in Fire Alarms, Camera Systems, CCTV, Access Control, and more.
When your monitored alarm is triggered a Central Station Alarm Monitoring Provider such as S.E.M Security Systems receives the alarm and then provides the alarm monitoring Call Verification that verifies the event and most importantly we place a 'Call to Dispatch' to the appropriate authorities once the monitored alarm event has been verified.
You are probably familiar with the basic burglar alarm system in homes that includes an alarm panel, motion sensors, glass break sensors, etc. There are also add-ons to the system you can take advantage of for added security. One such add-on is a panic alarm, which is designed to sound the moment they are activated.
Video surveillance (once known primarily as CCTV - Closed Circuit Television) has undergone a major technological re-definition (i-Cloud) in recent years. Their reliability and ease of use compared to the traditional 'Tape Based' (VCR) counter-parts is beyond imagination. Standard CCTV systems are most easily recognizable as the series of black and white video monitors we have all seen either at local convenience stores and other retail outlets.
With over 30 years of experience; of all services S.E.M Security provides, no single service has undergone more of a technological revolution than access control systems. What was once considered the realm of science fiction is now reality with systems that incorporate features such as finger print analysis, voice analysis as well as the ultimate in access control, retina scanning.

I dealt with the owner who was extremely arrogant. I recommend finding a local family company who will appreciate your business.

I have hired several different security company's and have been disappointed. Finally threw a recommendation I was told about S.E.M. they are used in my business as well as home. I DId my due diligence and found everything I was told was true. 1 They do what they say. 2 There is no bait and switch. 3 They do not over due a system just to sell you. 4 When they give you a time they show up and never miss an appointment. 5 Extremely reliable. 6 They are neat & clean up after themselves. 7 They are first in their class.
