Physical Security Systems

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?

Comparison of IP Cameras and Analog Cameras

Sony Dome IP Camera SNC VM632

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.

Technical Jokes and Cartoons 3A

We included the latest technical topics as well as some classic jokes from Henny Youngman, a comedian who was popular years ago.  He was known for his “one-liners”.  for example,

I’ve been in love with the same woman for forty-one years. If my wife finds out, she’ll kill me.

Comparison of Door Access Control Systems

IP Access Control System

Remember when door readers were connected to the central control panel and how difficult it was to run all the connections?

Oh wait, people are still doing that.  The new IP connected readers have been available for a number of years and it’s surprising that they haven’t made more of an impact in the market.  I talked to a number of people about this and the conclusion is that security dealers like to do what they know and find it difficult to work with computers and networks.

Are the IP door readers actually better, or as some people say, too expensive?

In this article, we reviewed the cost of the two technologies for an 8 door system.

IP Camera Low Light Test and Evaluation – Sony vs Samsung vs Axis

Samsung SSDR off WDR off

We tested a number of IP cameras so we could recommend the right camera for low light level applications.

Other key features include resolution, wide dynamic range, and frame rate, which we evaluated in our other posts.

In our latest product test, we compared the low light performance of the new Sony SNC-VM630, Samsung SNV-6084R, and Axis P3384 IP cameras.

The Samsung dome IP camera includes a built-in IR illuminator which we turned off for the test.

IP Camera Test and Review of Wide Dynamic Range – Sony vs Samsung vs Hikvision

WDR Dark

Some applications require IP cameras with a wide dynamic range (WDR). What is a wide dynamic range? It means that the video will look much better in situations where there are very wide light differences in the scene. You may have seen this type of problem, where you are viewing a person in front of a bright background. The background is clear, but the person is very dark and hard to see. The older IP (and analog) cameras used “Back Light” control to enhance the darker area (foreground) and ignore the background.

In this case, you can see the person but the background is lost in a bright haze. If there are people in the background you can’t see them. Today’s new IP cameras use a wide dynamic range to allow you to view both the foreground and background.

Wireless IP Camera Systems

Wireless Camera Systems

Wireless IP cameras can be used whenever you can’t wire the camera to your network switch. Cameras with built in wireless radios are used indoors, while cameras with external radios are used outdoors and in remote locations.

Cameras with built in radios are usually for indoor home use. But when it comes to outdoor use, cameras that use external radios are preferred because they are reliable and can cover much longer distances.

There are two types of wireless connections; Wi-Fi radios that use a dedicated connection between two points, and 3G / 4G that use the telephone wireless network.
