CCTV Systems

Written By:
Tuesday, March 22nd, 2011

The phrase CCTV systems can cover a broad range of different video camera systems.  Generally speaking, when we think of a CCTV system, we are usually referring to a video monitoring, surveillance, and/or security system.  CCTV is an acronym for Closed Circuit TeleVision however, more often then not in today’s age of technology, these systems are often called digital video security and surveillance systems.

CCTV systems got their name because of the way the systems were initially developed.  Closed Circuit Television basically referred to a system by which a video camera transmitted the video images it created through a cable directly to a monitor or Digital Video Recorder or DVR.  This differed from the studio broadcast television that sent their video images through an antenna out to the general public.  Anyone with a television or other type of receiver could view the broadcast audio and/or video image.

Today, CCTV systems are based on the same idea; however, the transmissions are no longer confined to being sent over a dedicated video transmission cable. A CCTV system today may send its video and audio wirelessly on a specific frequency to a specific receiver or they can even utilize the Internet to send their signals just about anywhere in the world (again, to a specific “receiver” or group of individuals).

CCTV systems today share some of the older terminology relating back to the original analog video systems.  For example, older analog CCTV monitors were actually electronic tubes, Cathode Ray Tubes or CRTs to be exact.   These tubes shoot electron beams in horizontal lines on the glass screens to produce a video image.   Thus, the clarity or resolution of these cameras was usually designated by the number of Television Lines or TVLs that it created.  Lower resolution cameras produced around 300 TVL and maximum high definition cameras produce up to 650 TVL.

The cameras and monitors today are digital, and therefore produce their images using pixels, tiny dots of color analogous to the dots seen in newsprint up close.  However, they often still use the TVL designation to define the resolution of the cameras.  One reason for this is that although CRT monitors are seldom marketed anymore, consumers may still have plenty of CRT type monitors they can use for their system.

Today, a complete CCTV system usually consists of one or more digital video cameras, a Digital Video Recorder or DVR, and one or more optional monitors.  Security Camera King offers several complete CCTV system packages to meet just about every security, surveillance, and monitoring need.   Our featured package systems are based on our three signature DVRS, the Elite-Mini, the Elite Series, and the Ultimate Series.

These package systems are further available based on the system being a 4, 8, 16, or 32 channel (camera) system.  Note:  The 32 channel system is only available with the Elite Series DVR.  Finally, we break each one of these packages down based on cable and power supplies.  We offer each system with either “plug ‘n play” pre-cut and connector fitted cables and space saving power supplies or with bulk cable, connectors, and a power distribution supply box.

Our Elite-mini and Elite Series systems come with the appropriate number of 420TVL Vandal Proof Indoor/Outdoor Dome Day/Night Infrared Vision cameras.  The cameras have an approximate infrared range in total darkness of about 50 to 60 feet.  The cameras have an outdoor rating of IP66 and so are very suitable for outdoor or indoor use (our part number for the camera is Product# OD-LX420IR50 for additional details and specifications).

Our Ultimate Series systems come with the appropriate number of 520 TVL Vandal Proof Indoor/Outdoor Dome Day/Night Infrared Vision cameras.  This cameras are true high definition cameras with a resolution of 100 TVL more than those above.  These cameras also have an approximate infrared range in total darkness of about 50 to 60 feet.  They are also suitable for outdoor or indoor use (our part number for the camera is Product# OD-LX520IR50 f0r additional details and specifications).

Security Camera King has put together this system packages to offer you the highest quality yet simplest to install CCTV systems on the market today.  By offering you these as complete system packages, we can make them available at competitive prices that are hard to beat anywhere else for equipment with the same features.  In addition, we allow you to make upgrades if necessary, so that you may “tailor fit” your system to your specific needs.

Tuesday, February 22nd, 2011

Security Camera King features several different digital video security systems and each of them is a web ready DVR security system. We take pride in offering the highest-quality most up-to-date security merchandise, and that includes our web ready Elite Mini, Elite Series, and Ultimate Series Digital Video Recorders or DVRs.

These days everyone’s work and personal situation is different so versatility is the key to digital video camera security system that can work for all. Security Camera Kings do-it-yourself security systems are easy to install and a cinch to set-up and operate. What’s more, since each DVR is a web ready DVR security system, once installed you can access your system anywhere in the world where there is broadband internet access, and that includes using your 3G or 4G smartphone.

There are several ways of using the Internet with digital video security system components. These components are usually designated as IP or Internet Protocol ready, such as an IP Digital Video Security Camera. They are also referred to as “Web ready” such as a Web ready DVR security system. In the following article, we’ll take a look at the differences between IP ready cameras and IP or Web ready DVR security systems and look at some of the benefits or features of a Web ready system.

Web ready digital video cameras are different from ordinary digital video cameras in that they do not directly connect to the DVR. In fact, Web ready cameras don’t have to connect to a DVR at all. Web ready or IP cameras use the internet as a vehicle for networking. They can connect to a DVR remotely, thousands of miles away, via the internet. They can also be viewed and controlled via the internet.

Each IP ready camera contains its own web server technology and connects directly to the Internet via a broadband internet connection. The connection is usually via a Cat 5 Ethernet cable or wirelessly to a wireless broadband modem or router. Of course, most are WiFi compatible. The camera’s digital information is streamed over the Internet. It may be downloaded and saved on a personal computer or Internet connected DVR and it can also be viewed live using a personal computer, a Web browser, and an Internet Connection.

Another way of taking advantage of the versatility of the Internet is by using a web ready DVR security system. Like the IP digital video camera, the DVR contains the Web server technology. However, having a web ready DVR security system is far more powerful that just a Web ready camera.

In a typical Web ready DVR security system, each camera connects directly to the DVR first. It may do this using a video data transmission cable such as an RG-59 Siamese cable or it may connect wirelessly using an on-board transmitter and a corresponding receiver that is connected to the DVR. The system can be used like any non-web ready system. The cameras send their video data to the DVR unit which also includes a Digital Signal Processor that runs on an operating system. The unit compiles the camera’s data and creates a digital video file that can be stored on the DVR’s hard disk drive and/or viewed live on a monitor.

However, since the Web ready DVR security system is connected to the Internet, the cameras may also be monitored remotely, anywhere in the world there is broadband internet access (including smartphones). You can even record them remotely, as well as on the parent DVR. But there are some additional benefits as well.

For example, any Pan-Tilt-Zoom (PTZ) camera not only can be monitored remotely but can be controlled remotely via the Web ready DVR Internet connection. Security Camera King’s featured systems support two-way audio over the Internet as well. Further, the DVRs support up to 10 network or Internet users simultaneously.

Also, many web ready DVR security systems require a static IP address that normally will cost extra through your Internet Service Provider or ISP. Our web ready systems use Dynamic DNS support, which means a static IP address is not necessary.

Last but not least, our Web ready DVR security systems also support standard POP email accounts. This means you can program the system to email you anywhere at anytime based on several different triggers that you set.

So when it comes to versatility Security Camera King’s Web ready DVR security systems do it all.

Color Security System

Written By:
Friday, February 4th, 2011

Color Security SystemA digital video color security system is a video camera based protection and monitoring component system. Although a bear-bones system may only require two separate devices to operate, it normally consists of three or more. At a minimum a color security system requires at least one camera and a Digital Video Recorder or DVR. However, if you want to be able to watch what your system is recording, you will also want to use the third component, a color monitor.

The “work flow” of a color security system begins with, and is really based on, the digital video color security camera. A color security system may have only one camera, or it can consist of as many as sixteen when the system utilizes one DVR. The camera or cameras send their color video data to the DVR unit which contains an on-board computer processor designed specifically to do work with color video data and coordinate the color security system functions. Once the processor has interpreted the digital data from the camera, it compiles the data into a digital video file which can be viewed live if a monitor accompanies the system and/or saved for later use on the DVR hard disk drive.

The digital video camera in a color security system records digital images by converting light energy into electrical energy. It does this using one of two different sensors that create measurable electronic charges when light strikes their photosites. The sensors are known as Charged Coupled Devices or CCDs or Complimentary Metal Oxide Semiconductors or CMOSs.

These sensors have tremendously small diodes in an incredibly small amount of area. Most color security system cameras’ sensor chips are less than 1/2 inch square in size. The lens focuses the light image on this small area, which on a typical 1/2 inch CCD can contain 300,000 to 500,000 photosites. The sensors’ photosites are usually designated to detect red, green, or blue light. This configuration is often called a Bayer filter. When the data from all of the red, green, and blue sensing diodes or photosites is compiled it creates a high quality electronic color image.

The color security system further processes the electronic image by passing it through an on-board circuit chip called an analog-to-digital converter. This converts the electronic analog signals into binary or digital data that is then transmitted in a variety of ways, one of the most common being along an RG-59 coaxial video transmission cable. (Signals can also be sent wirelessly via radio waves).

The other end of the cable is connected to the DVR unit. The data from the color security system camera is still unrefined and it is the responsibility of the DVR unit with its accompanying Digital Signal Processor or DSP to add the finishing touches. It does this by using a utility, either in software form or contained in an on-board microchip, that reduces the size of the otherwise incredibly large digital video file without sacrificing a significant amount of quality.

Digital video, like cinematography, actually consists of several photographs (digital-based in this case) that are taken in a very short period of time. The human eye and brain are slow enough to fool into thinking they are seeing fluid, motion video if the photographs pass by quick enough. The number of photographs taken in one second is usually called the “frame rate” and is designated as “frames per second” or fps and is typically around 29 fps.

Consider the file size of a typical high quality digital camera. Now multiply that size times 29 and you have the size of the digital file for one second. Multiply that times 60 seconds, and again times 60 minutes, and the result for one hour of video at that rate is 104,400 times the size of one digital photograph. You can appreciate how large the file size can be.

Every color security system uses a form of the utility mentioned above. One of the most recent and efficient COmpression/DECompression or CODEC utilities is the H.264. Using the CODEC makes the files much easier to handle and increases maximum storage capacity of the DVR.

Security Camera King features several different color security systems including our Elite Mini, Elite, and Ultimate DVRs. We’ve designed our color security systems to give you the freedom to change components to make the system fit your specific needs. Contact one of our security experts today for more information.

Security Flood Light DVR Camera

Written By:
Thursday, January 20th, 2011

Nothing says “”Gotchya!” to a potential intruder, vandal, or burglar better than a security flood light DVR camera. Thanks to modern technological improvements these devices are an entire compact digital video security system. They can be used in both residential and commercial applications and can be extremely effective when placed in the proper location.

Not only does a security flood light DVR camera help to protect and prevent perpetrators from causing damage or breaking and entering, but it also offers positive deterrence. It’s already been proven by the law enforcement agencies in London, England and New York City that the mere presence of digital video cameras deters criminal activity.

However, the security flood light DVR camera takes it one step further. Not only does it record still digital photographs or digital video images of the intruder, but once the unit senses motion, it snaps on a powerful high wattage flood light illuminating the surrounding area and “spotlighting” the intruder as well.

In addition to protecting homes and businesses, these units are great for protecting other property as well. Boat docks with electricity, barns, storage areas, specific portions of land, back entrances of retail stores, and no-trespassing industrial areas as well can benefit from the protection of a security flood light DVR camera.

The units are relatively easy to install and use as well. Basically, all that is required for installation is to mount the unit, connect it to a standard residential type power line, and select the settings you desire. Then walk away and be confident that your security flood light DVR camera will protect you and/or your family, business, or property.

Before we provide some detail about the design and function of a standard security flood light DVR camera, let’s briefly describe a typical digital video security camera system and how it works.

Most standard digital video security camera systems contain one to several cameras, a Digital Video Recorder or DVR, and perhaps a monitor. The cameras are mounted in various strategic locations and send their digital video data to the DVR unit by means of a digital video cable run from each camera to the unit, or wirelessly using radio signal transmitters and receivers.

The DVR unit, much like a highly specialized personal computer, contains a hard disk drive like those found in computers. The DVR unit processes the digital data and creates a digital video file that can be viewed live on a monitor and/or saved on the DVR for later use.

A security flood light DVR camera is basically a miniature version of the basic system without the monitor. The unit contains all the devices (sans the monitor) within one relatively small, compact fixture. The floodlight is usually a powerful 500 watt halogen flood lamp. These lights can project a powerful beam of light in a relatively wide field of vision.

Connected to the light, DVR, and the camera is an infrared motion detector. The motion detector, known as a PIR or Passive InfraRed sensor, can detect the infrared radiation emitted by the objects in its field of vision. When this “heat signature” changes greatly or rapidly, the sensor interprets this as motion. The sensor activates a relay that switches the security flood light, DVR, and camera on. Depending on the model, the entire unit switches off either after motion is no longer detected or specified time period after the initial “On” state.

When the camera is switched “on” it immediately begins capturing digital video images (or stills), with the flood light helping to provide a crisp, clear, bright picture. An on board processing chip saves the data either as digital photographs or digital video files to the DVR.

The DVR in this case is not a large hard disk drive, but usually consists of an SD card (Secured Digital card), a compact flash card, thumb drive or similar mini-portable memory device. All the user needs to do is remove the SD card, transfer the files to their personal computer and view, print, or make movies disks of the saved data.

Although a security flood light DVR camera cannot provide the extensive precise coverage of a full size standard digital video security system, it does offer an economical alternative and can be quite useful for specific situations.

IP Cameras Security Surveillance

Written By:
Friday, January 7th, 2011

One of the ever increasing most popular digital video camera security systems is the IP cameras security surveillance. This camera system is unique in that it utilizes the internet as a medium for sending video images and remotely controlling the camera making accessibility nearly ubiquitous throughout the world.

There are a few variations on the theme on how these cameras and/or camera security systems operate, but the end product is the same. A digital video file that can be viewed virtually anywhere there is broadband internet access and stored on a personal computer’s hard drive for later use or archiving.

Let’s take a quick look at an average standalone digital video security camera system and how it works so we can better understand how IP cameras security surveillance systems work. A standalone system is so named because it can be used by itself without any additional outside equipment (i.e. other than the standard system equipment, no additional PC or other device for example is required).

A typical standalone digital video security system contains one or more digital video cameras, a Digital Video Recorder or DVR with a Digital Signal Processor or DSP, and a monitor. The digital video cameras in these systems capture light images and transform them into electronic video images. The camera normally contains an analog-to-digital processor chip that sends the video image data in binary or digital form to the DVR unit.

The DVR unit consists of three primary types of devices; the Hard Disk Drive (HDD), the DSP previously mentioned, and any additional peripheral type devices such as CD or DVD recorders to make portable copies of video files. The digital signal comes from the camera via an RG-59 coaxial video transmission cable to the DVR unit. Each individual camera must have its own cable run from the camera to the DVR unit.

When the data reached the DVR unit the DSP processes the data, applies a COmpression/DECompression utility (or CODEC) that greatly compacts the information and reduces the final size of the digital video file. The digital video files is then viewed on a monitor (live) and/or saved to the HDD for later use.

IP cameras security surveillance systems differ in that they normally connect to the Internet instead of using a video transmission cable to relay the camera data to the DVR unit. Furthermore, IP (which stands for Internet Protocol ready) cameras do this normally by one of two methods; either the data is sent via a Cat 5 Ethernet cable to a router or modem or wirelessly to a wireless router or wireless modem.

Using the internet, especially the wireless technology, creates a great advantage for this system. Once the signal make it to an Internet connection the cameras can be viewed and/or controlled from anywhere in the world that broadband internet is accessible. This includes working in tandem with devices such as a Personal Computer or Mac Computer, iPhones, iPads and the like, and many 3G and 4G smartphones. Literally, you can see what is going on at home in Miami when you are on business travel in Paris.

Another advantage of the IP cameras security surveillance system is the ability to use wireless internet technology. This eliminates the need to run the RG-59 coaxial cable from each camera to the DVR unit, greatly reducing installation time and making the process a do-it-yourself project that is a snap.

IP cameras used for security surveillance are able to work by processing the video signal on board and sending it via the camera’s on board web server technology. A variation on this theme is the IP DVR. In this instance the standard cameras are used in conjunction with the DVR but the DVR has the IP capability and is connected to a router or modem. The files are stored on the DVR units HDD but are accessible via the internet to the user.

On the receiving end of an IP camera security surveillance system that uses a personal computer the digital video files are stored on the computer’s HDD and viewed on the computer’s monitor. Normally this systems work in tandem with common internet browsers such as Internet Explorer, Safari, etc. Installation setup normally consists of a self installing software CD so for many systems no prior computer networking knowledge is needed.
