CCTV Camera Security System

If you are seeking total security and protection at home or at the office, try a Closed Circuit TeleVision or CCTV camera security system.  There are many different types of systems for just about every application and budget.

Due to advancements in computers and electronics, CCTV Camera Security Systems have become so versatile that it’s actually hard to find an application that they can’t cover.  Let’s take a look at how a CCTV Camera Security System
works then will review some of Security Camera King’s specific models.

First, the term “CCTV” is a carryover from the earlier analog systems.   A CCTV Camera Security System was so designated be cause the entire system was connected by cable in a closed circuit.  This was contrary to a typical studio analog system where the camera recorded the image and past it along to a control room where it was manipulated and amplified and sent out to a fairly large and tall antenna.  Under this system, anyone with a TV could become part of the system (by tuning their TV to the right channel).

A closed circuit television system by comparison was designed to be seen by only those who were directly hard wired into the system, hence the term “Closed Circuit.”  Today, the term is used a little more loosely, but the general meaning still applies.  Even though there are cameras that are wireless and therefore transmit their signals via an on-board antenna, the radio signal is usually a vary specific frequency that designated receivers or DVRs possess to receive the information.  In other words, a CCTV camera security system is still meant for only those people to receive that are within the defined circle of users.

CCTV camera security systems are rapidly becoming the system of choice for both commercial and residential applications.  One of the reasons for this is because the system is digital.   Since the system is digital, it is able to share a lot of the same equipment and programming as a typical personal computer. This has great beneficial implications for a CCTV camera security system.  For example as hard disk drive technology increase creating storage capacities well into the Terabyte (TB) range, the video security camera system can take advantage of this large storage because video files are stored on such a mechanism.  Greater storage capacity yields a longer turn around time before the DVR re-writes older video files with new ones.

Today’s CCTV camera security systems are basically component systems which provide even for flexibility.  Generally, cameras and other peripherals to the Digital Video Recorder can be mixed and matched to the users utmost benefit.  For example, a typical 8 channel system may have 2 vandal proof dome cameras, an indoor box camera, 3 outdoor dome cameras that also have infrared “vision,” a door monitor camera with two way audio, and a Pan-Tilt-Zoom or PTZ camera covering the driveway and street entrance.

Security Camera King offers a tremendous variety of components to create your own tailor-made system.  Basically, these systems are based on the DVR’s that coordinate them.  Therefore, Security Camera King has 4 of their own proprietary DVRs so we’ll take a quick look at the four.

Elite Mini Economy

This DVR carries the same basic features as the other DVRs with a few exceptions.  It only has VGA and BNC connectors (no HDMI).  A PTZ control interface is also absent on this entry level DVR.  This DVR can record CIF quality on all channels at once, with D1 quality on channel one, all at 30 fps.

Elite Mini HD

This system has everything the Elite Mini Economy has except it does have an HDMI interface and can display high definition at 1080 p.

Elite Series

The Elite series has a multitude of features.  It offers everything the Elite Mini’s offer and more.  For example, in addition to camera hooks up that Elite DVR can accept alarm input channels and alarm output channels.  It can produce a display in High Definition (1080p) but also has video loop output options as well as video matrix output.  This DVR also contains a DVD-RW burner for making backups of digital video files held in storage on the hard drive.  PTZ control is also avilable on this model.

Ultimate Series

The ultimate Series has everything that the Elite has to offer with the significant difference being in recording power.  The Ultimate Series DVR package includes 520 TVL cameras and can record 704-480 at 30 fps on all channels simultaneously.

School Security Systems

Written By:

These days school security systems consist of a little bit more than just a truant officer of the 1970′s and before.   Thanks to always evolving technology and reduced prices, a digital video security camera system usually plays a big part in school security systems as well as maintaining order within the classroom.

Many schools have gone to total digital video with a camera with audio in every room.  This provides superior documentation in the event of a student disturbance.  Likewise, the “camera in every room” policy can not only protect teachers but can protect students as well especially by documenting teacher-student situations as they occur.

The whole idea of installing a digital video camera in every classroom is not as far fetched as it may seem.  After all, before the advent of cheaper yet higher quality digital video systems, most schools used an older method of communication; the intercom.

Today, we have the advantage of disposing of the intercom and using the digital video school security system.  Not only can the school’s front office communicate with the teacher (or student) in the room via two-way audio, but a video image can be seen at the same time.  Should there be any doubt as to an altercation between two students or between a student and teacher, the entire episode is captured and recorded on the Digital Video Recorder or DVR which is usually located in the front office.

There are a variety of digital video camera security systems that can be used as school security systems.  Security Camera King has an ample supply of equipment and down-to-earth reasonable prices.  To equip a school properly, all rooms should contain at least one camera.  This includes the cafeteria, gymnasium, band room, as well as each class room.

Typically, Security Camera King’s complete 32 channel Elite DVR security camera package will do the job.  If 32 cameras are not enough to adequately monitor the school, then more (4, 8, 16, or 32 camera) systems can be added until the optimum number is achieved.

Security Camera Kings 32 channel system is particularly useful in this situation.  First of all the unit comes with 32 420TVL infrared cameras.  This means you get 24/7 full coverage.  During the daylight hours the camera captures highly detailed color video and at nighttime when school is over for the day and the lights are out, the infrared (IR) technology is automatically switched on and video camera coverage continues.

However, it is not necessary to use all of the same cameras for the entire system.  For example, if you want to include surveillance of a parking lot, you could upgrade a camera to a Pan-Tilt-Zoom (PTZ) camera.  A PTZ camera is an incredibly versatile camera that allows the user to move the camera horizontally (Pan), vertically (Tilt), or zoom in on an object.  In addition a PTZ camera usually has the ability to track and follow objects such as people and vehicles.  This would provide a good handle on who is approaching the school from the outside.

All of Security Camera King’s DVRs are internet ready, so when installing your system, don’t for get to supply the DVR with an active Ethernet Cat5 cable.  Once connected to the internet, the principal, superintendent, maintenance personnel  and any one else as necessary can be set up to monitor the entire system remotely from their smartphone.

Security Camera King’s school security systems are designed to be easy to install, so easy that a maintenance employee should be able to install the system with absolutely no problems.  However, should some sort of difficulty occur, our support team of security experts are readily accessible to help you every step of the way.

In fact, our security experts can be contacted on-line by using “Live Chat” or by telephoning 866-573-8878 Monday through Friday from 9AM to 6PM EST.  They will walk you through every step of the process from the very beginning to the very end, if need be.  They’ll even help you design your system to determine what kind of equipment, how many cameras you’ll need, and so on.

So if you’re looking for a solution for theft, burglary, vandalism, bullying, student discipline and documenting student to student or student to teacher behaviors a school security system sounds like just what the doctor ordered.  We’d love to help you upgrade your school security system, so please, contact us today.

Evaluations Of Camera Security Systems

Written By:
Tuesday, January 4th, 2011

In this article we will talk about evaluations of camera security systems and what you need to do and know to perform your own evaluations of camera security systems.

Evaluation of camera security systems can be difficult to do comparatively because of subtle differences in manufacturers’ digital video systems; so when trying to determine what system type or component to purchase, consider performing your own needs assessment first. Then search for the equipment that satisfies those requirements. Finally, you can compare different manufacturers’ or vendors’ brand offerings and prices.

Let’s cover the basics of performing a needs assessment based on the technological capabilities of digital video camera security systems. In order to make things a little easier to compare, we’ll break up the system into its three component parts and consider each component separately.

A typical digital video camera security system consists of one or more digital video cameras, the Digital Video Recorder or DVR, and a monitor. We will confine our evaluations of camera security systems here to standalone systems only.

First, determine what you need to protect or monitor. A room, a building, land, property located outside or inside, a parking lot, people, shoppers, cash register or teller areas, etc. Once you know exactly what you need to record, you can move on to deciding how you will record it. This is where the expertise of a professional installer is particularly helpful. An experienced installer can assess your situation and determine the precise placement and minimum number of cameras needed to do the job.

Once you know how many cameras are required, you can begin to narrow your evaluations of camera security systems. Generally speaking, the maximum number of cameras in a system determines the type of DVR that you will need. Customary DVR camera configurations include four, eight, and sixteen potential cameras (Note: The number of cameras is also referred to as “channels” which is not to be confused with another use of the word “channels” that describes specific radio frequencies). If a system requires more than sixteen cameras additional DVRs are used to satisfy the need.

So let’s assume our system will require seven cameras. We now know we will need an 8 channel DVR, but we aren’t ready to select the DVR just yet. Now let’s go back to the cameras. Of our seven cameras we know that four will be used outside and three will be used inside.

Now you must ask yourself what kind of digital video monitoring do you need? Do you require full time (24/7) day and night, do you track or follow objects (cars and people for example), and is audio required, and so on. Once you know the exact requirements of the camera you can determine exactly what type of camera you will need.

Let’s assume we need four outdoor, wireless, night vision infrared digital color cameras with a motion detector. These cameras will also be battery operated. In addition, we’ll need three indoor cameras without any special functions. However, we do need to determine how we will mount these cameras so we know what type of camera we will need for each of the seven cameras (dome, bullet, or box type cameras).

In performing your evaluation of camera security systems for this set-up you will also need to purchase a four channel receiver unit (a receiver unit that can accept four camera inputs and receive each on a separate frequency). This unit will be attached to the DVR. Speaking of which, we can now return to the DVR to consider what to purchase.

We know we need an 8 channel DVR. Do you want to be able to record for long periods of time without erasing over pre-recorded monitoring? If so, you should consider a DVR with a large capacity hard drive. Do you want to make copies of files on DVDs/CDs or other media? Do you need the DVR to connect to the internet? These questions will help determine the type of DVR you require.

Finally, ask yourself what type of monitor you will need. Will the monitor be used for setting up the system and occasional use or will the monitor be watched the majority of the time? (Monitors used for setup can be very small; monitors that will be used frequently should be large enough to view all seven cameras clearly).

After considering what we need, we can now perform evaluations of camera security systems to determine the best prices and products for our application.

Camera Security Systems with Cameras

Written By:
Monday, August 16th, 2010

Digital video camera security systems with cameras are the one of the most popular anti-theft, alarm, and surveillance systems in use today. Innovative technology including advancements in the digital video camera industry and computers have made these security devices not only versatile for use just about anywhere, but low in cost to be so economical that businesses and residences alike are using them for protection.

Camera security systems with cameras are basically component systems; they are individual pieces linked together to operate as one system. This produces several advantages for the system as a whole. First, individual parts or devices of the system can be made by different manufacturers. In addition, these components can be purchased so that each individual part is highly customized to serve a specific need, while maintaining the integrity of the total system. This allows “mix and match” system building.

Typical digital video camera security systems with cameras contain three major components: 1) Cameras; 2) Digital Video Recorders or DVRs; and 3) Monitors. Keep in mind that since these are component systems, every system can vary in the number of basic and additional components used. For example, camera security systems with cameras used for industrial areas may contain 16 or more cameras whereas residential camera security systems with cameras may contain only two or three.

Further more, each component type of the system can be different to accommodate the needs of the user. That is, a residential system may have 5 cameras, with each camera being of a different type or for a different function. One camera may be an outdoor camera with day/night vision that monitors a driveway, another may be an outdoor camera with day/night vision and audio recording for monitoring the front door, and a third camera may be an indoor camera that monitors the living room and hallway areas. A fourth camera may be an infrared night vision camera used as a baby monitor and a fifth and final camera may be a motion detection activated camera for protecting a home office. All of these cameras can be used together easily in tandem even though each one may be a different type and model.

In fact there are many features and/or options available for each component of the system. The following is a partial list of the most common features/options available for the components of camera security systems with cameras:

Cameras
• Box, dome, and bullet shaped cameras
• Indoor/outdoor cameras
• Extremely sensitive day/night vision cameras that use very little visible light
• Night vision infrared cameras that use near infrared radiation to illuminate their targets (this “light” is invisible to human eyes)
• “Wireless” cameras that send their video signal via radio waves instead of coaxial cable
• Cameras that record both video and audio
• Internet Protocol or IP ready cameras that can be immediately connected to and networked via the internet
• Cameras that capture high quality black and white or full color video
• Pan-tilt-zoom or PTZ cameras that can vary the position of the camera to increase its field of view — when used with additional programming for the DVR unit these cameras can even track or follow a moving object
• Hidden or disguised camera types for covert monitoring

Digital Video Recorders
• Various storage capacities are available from Gigabytes to Terabytes — the larger the storage capacity the longer the recording time capability and/or the larger the number of cameras being recorded
• Flash card digital recorders are available for small, light-weight portable digital video recording
• Various COmpression/DECompression utilities or CODECs are available for creating digital video files
• Internet ready DVRs that can be networked using the internet
• DVRs that can handle 4, 8, 9, or 16 cameras at one time

Monitors
• These days, most monitors are the equivalent to LCD computer monitors so they can vary accordingly in size, type and resolution
• Small individual camera monitors are also available
• Individual use wireless monitors such as those used as baby monitors

As you can see, camera security systems with cameras have a tremendous variety of features and additional options that make them incredibly versatile. These features combined with the component functionality of the system make them useful for the largest business as well as small residential use. In addition, technological advancements have resulted in economical pricing making these systems affordable for just about anyone.
