What is the Right Sound Level for Your Paging Speakers?

Posted on December 17, 2014June 17, 2021 by Bob Mesnik

Whether it’s an emergency announcement or page in a school, how do you determine the speaker and amplifier required for a specific location? IP paging systems can provide exactly the right sound level to exactly the right location, but what is the right sound level?

How loud does the emergency paging system need to be? How much sound is needed to hear an announcement in a classroom or in a sports field where there is a lot of background noise?

This article provides the technical background and practical information needed to help you determine the right power and speakers required.

Actually many of these jokes are not really technical, but us tech guys think they’re funny…

Answering machine message,

“I am not available right now, but thank you for caring enough to call.

I am making some changes in my life. Please leave a message after the beep.

If I do not return your call, you are one of the changes.”

In Cases of Emergency

Posted on December 11, 2014June 1, 2020 by Virginia Fair

An emergency once set in motion, can not be taken back. All we can do is assess the situation, spread the word, then throw roadblocks in its way. No one knows this better than those responsible for school safety.

Whether it’s the principal, vice-principal, or security officer, all he or she can do when an emergency looms is is learn as much as he/she can, and based on the specific situation, alert teachers and students in classrooms – and oh, yes, hope that the countless hours spent in repetitive fire, evacuation, or lock-down drills have taken root.

The good news is that if the school is protected by an IP Physical Security System, they’ll have a head start.

VCA and Safe/Smart Cities: Applications of the Future

Posted on December 3, 2014June 1, 2020 by Virginia Fair

Cities are getting smarter and safer, thanks to VCA and video surveillance. But before we get started, let’s define the difference between VMS and VCA which is actually a trick question since Video Content Analysis (VCA) stems from algorithms written into Video Management Software (VMS).

Also, known as Video Analysis, VCA analyzes streaming surveillance video to detect spatial and temporal events.

The earliest applications were used to alert security personnel to the real time presence of intruders, loiterers, unattended packages, and cars in a no park zone.

Surveillance News Flash!

Posted on November 17, 2014June 1, 2020 by Virginia Fair

It’s always rewarding to find that one of the technologies we specialize in has been cited in a story. Wednesday, November 12 was just such a day.

An article in The Journal News which covers our area, New York’s lower Hudson Valley bore the headline Harrison Cops Bust Cul-de-sac Burglary Ring.

The arrests came after a two-month long investigation by the Harrison, NY Police, the Westchester County District Attorney’s Organized Crime Division, and the Special Investigation Squad of the Bergen County, NJ Prosecutor’s Office into what grew to be twenty-five break-ins in the tri-state area. The burglary ring would strike the expensive homes between 10 AM and 1 PM, when no one appeared to be at home, to steal jewelry and other property, often hauling away safes that contained them.

Seven burglary suspects were taken into custody as well as a Diamond District Dealer who was acting as ring leader and “fence.” The capture could not have happened without the cooperative effort of the three agencies who trailed the suspects for weeks into nearby New York, Connecticut, and New Jersey, using the latest forensic technology to obtain evidence – video from IP security cameras, and information obtained from police license plate readers.

“Lexophile” is a word used to describe those who have a love for words, such as “you can tune a piano, but you can’t tuna fish”, or “to write with a broken pencil is pointless.” Here are some examples:

The batteries were given out free of charge.

A dentist and a manicurist married. They fought tooth and nail.

A will is a dead giveaway.

With her marriage, she got a new name and a dress.

A boiled egg is hard to beat.

Digital Doorman on Duty

Posted on November 12, 2014June 1, 2020 by Virginia Fair

One of the draws of the luxury apartment buildings on New York’s Park and Fifth Avenues has been the access control provided by uniformed doormen; trusted employees who know every resident by sight and can be counted on to screen all visitors and grant them access only after announcing them and gaining permission over the apartment’s intercom.

The cost for such security: co-op and condo prices that reach into the two-digit millions. But there’s an alternative for those of us who cannot afford to live in such luxury – a digital doorman.

Long Range IR PTZ Cameras – How Long is Long?

Posted on November 4, 2014June 1, 2020 by Virginia Fair

IP surveillance cameras are ubiquitous today. Everyone who sets foot out his door is well aware that somewhere, sometime on his journey he will enter into and out of several cameras’ fields of view.

Since very few everyday security cameras are covert, one has only to look several feet up at buildings, light poles, retail store ceilings to see this is true. There is a reason for this – the sight of a surveillance camera can be beneficial in deterring crime.

But there are also cameras capable of surveying an area, sight unseen, from, literally, miles away. These surveillance cameras fall under the heading, long-range cameras.

Physical Security Systems

Posted on October 31, 2014June 1, 2020 by Bob Mesnik

A physical security system is a collection of equipment and software that provides security and safety. It can use a variety of network-attached devices as well as a number of software products that can be integrated to provide a unified solution.

To be more specific, the integration of the latest video management software (VMS), with door access control software, and emergency paging software along with IP cameras, IP sensors, IP door readers, and IP paging amplifiers can provide a very complete physical security system. These IP based security systems provide similar capability to Physical Security Information Management (PSIM) software at much less cost.

Are IP Cameras Better Than Analog CCTV Cameras?

Posted on October 24, 2014June 1, 2020 by Bob Mesnik

Comparison of IP Cameras and Analog Cameras

Why should I use an IP camera when the analog cameras are so much cheaper?

That’s a question we get especially from those people who have been using analog CCTV (closed-circuit TV) systems for many years. Actually CCTV has been around for over 45 years. Olean, NY was the first municipality in the US to use cameras on its main street to help reduce crime (according to Wikipedia this was back in 1968).

Not only have the analog CCTV systems been around for a very long time, but they also haven’t really changed from their original capability. Well yes, they have gotten much cheaper, and there are efforts to use higher resolution cameras, but their capability hasn’t changed. The first systems were based on the TV standards established by the National Television System Committee (NTSC). The standard indicated that there should be 525 vertical TV lines, with a frame rate of 30 frames per second. Take a look at our video, How the Video Camera Works.
