internet surveillance cameras Do you fear what is happening in your home when you are not there? For these homeowners, Internet security cameras offer much security. They are easy to install and offer great security. There are many options on the market today. New options are being developed each day. However, understanding the basics will allow you to make an informed decision on what is right for your home. Homeowners interested in installing an Internet security camera often become confused about the specifics that they need to look for. It really becomes an individual choice once the homeowner understands the basics.

Important Points to Remember When Purchasing an Internet Security Camera

Each Internet security camera system requires a network video recorder. This recorder acts as the brains of the Internet security camera system. It controls the configuration, it allows the user to playback the photos, it allows the user to expert the data for other users and it allows the Internet security cameras to connect with other Internet devices depending on the user’s direction.

Internet security cameras are a great asset in a home security system. It is, however, only as good as the monitoring that accompanies the system. Unless you are prepared to look at the feed 24 hours a day, 7 days a week, it may be wise to also hire a monitoring company. The monitoring company can alert emergency personnel when needed to your address.

Internet security cameras are either analog or PTZ. Users need to decide which is right for their individual circumstances. The main advantage of an analog camera is the cost. The main advantage of the PTZ system is that it can zoon in on user demand to get better photos. Whichever system is chosen, make sure that the camera will capture a 360 degree view and has the ability to track the main subject in a scene.

Look for an Internet security camera that will allow the user to install a large SD card. While the main recording is done in the network video recorder, the SD card can be an important back up system. The more memory the SD card has the more information that can be captured on it. If there is an interruption in the network, then the SD card will still capture the information should something occur. It is also important to also consider the amount of bandwidth the system will use and the cost of that bandwidth.

It is important to consider the power source when purchasing a camera. Internet security cameras require electricity. Think about this before you buy the camera as it may determine the type of camera that you ultimately purchase.
It is also important to consider the best color of camera to purchase. No one wants an ugly Internet security camera or cables. Both are available in a multitude of colors. Buying the right color will also help the camera and cables blend into the background.

Types of Internet Security Cameras

Internet security cameras come in several basic types. Each types has its own advantages and disadvantages.internet surveillance cameras
The first type of Internet security cameras are box cameras. These are the most popular option. They are used in many businesses and in some homes. They are usually rather large and may deter some crime by their mere presence. When purchasing a box Internet security camera it is very important to consider what type of lens is right in each circumstance. These cameras work best in circumstances where there is enough available light to take the photo. The box camera can be equipped with infrared lenses to take lights in low light circumstances. The box camera can also be installed in special housing to make it waterproof. Remember whatever type of box camera you choose that you install it so that it will cover the majority of the room. These cameras only take photos in one direction. It is important to keep this in mind when installing the camera and figuring out how to power the camera.

The second type of Internet security cameras are dome cameras. These cameras are more attractive to some homeowners because it is hard to tell exactly where the dome camera is taking the photos. These cameras are easy to install and waterproof dome cameras are available. Look for a dome camera with interchangeable lenses so that the homeowner can be assured of having the right lens should circumstances change. Like the box camera, these cameras are only capable of shooting in one direction. Expect to cover only about 25 percent of a room with a dome camera.

The third type of Internet security camera is the PTZ camera. These cameras are among the most flexible on the market today. PTZ cameras work best when mounted in open situations since PTZ cameras take 360 degree photos with a fisheye lens. These cameras take their name from the fact that they can be remotely panned, tilted and zoomed. This is a distinct advantage in monitored security systems where someone is actively watching the system all the time. These are the newest Internet security cameras and the quality continues to increase.

The fourth type of Internet security camera is the bullet camera. These cameras come in two different sizes. They are usually the least expensive option on the market. The homeowner gives up a clear photo in exchange for the cheaper price. These cameras are usually waterproof so they make a great option for outside use without modification. Most bullet cameras do not have interchangeable lenses so it is important to know where you are going to place the bullet camera before you buy it, so that you can buy a camera with the right focal length lens. It is nearly impossible to find support for these cameras. These cameras can only shoot in one direction, so make sure that you install the bullet camera in exactly the right place.

The fifth type of Internet security camera is the spy cameras. Basically, spy cameras rely on analog. It is possible to buy an Internet security camera that is hidden in a clock, pen or almost any other device. Make sure to check out the individual device as many manufacturers are trying to get too much technology into too small a package. The result is unclear photos or problems connecting to the Internet. Make sure to know the local laws where you intend to use these devices. Spy cameras can be hidden in clocks, pens and almost anything else. These cameras only take photos in one direction so strategic placement of the spy camera is mandatory. Look for a camera that will not make any noise and will work with the available light. These cameras are great for people who may need to move the camera around depending on different circumstances in the home. Most spy cameras are small enough to be carried with you on business trips or when someone else is using your car.

internet surveillance camerasBuying an Internet Security Camera by the Number

Regardless of the type of camera that one is considering purchasing, there are three factors that need to ultimately be considered.
The first of these considerations is the frame rate. It is often known as the FPS rate. This is the frames per second that the camera can be operated at. The top FPS is 30. The lower the FPS is the less fluid the pictures coming from the camera will be. A lower FPS will result in photos that are intermittent. If more than one camera is connected to the same network, the FPS for the entire system must be considered.

The second number that needs to be considered is the television line. This number is especially vital for analog cameras. The higher the number, the better the picture will be. The top television line number is 700. Look for numbers close to 700 to make sure to get crisp, clear photos.

The third number that needs to be considered is the megapixel number. Security cameras should have at least a 5 megapixel. Generally, the higher the megapixel, the lower the FPS number will be. It is a trade-off that must be carefully considered. Higher megapixels will allow the authorities to enlarge a single frame, while authorities can also learn much from watching the mannerisms in a moving film. Researchers are working at finding solutions that will allow cameras to have both higher megapixels and higher FPS.

Taking time to investigate all the options on the market is important before you buy. First, consider what you want the camera to accomplish. Consider how you will power the camera and associated equipment. Then, consider how the camera will blend into your existing décor. The next step is to consider the type of security camera that is right for your budget and your circumstances. Finally, look at the numbers. Consider the FPS, the television line and the megapixels. Understanding the basics will help you make the right decision to begin with. Each circumstance is different and there is no one right answer for everyone. Now that you are armed with the right information making an informed decision is easy. Visit Security Camera King’s inventory today to find the right Internet security camera for you.

Wireless Security SolutionsTwenty first century electronic technical advances have created more reliable yet cost effective wireless security solutions than ever before. Most wireless security solutions are generally easy to install and simple to operate. In fact, they are often considered as do-it-yourself type projects and are specifically designed with that intention in mind.

There are basically two types of wireless security solutions, wireless security alarm systems and wireless digital video security camera systems. Each takes advantage of up-to-date wireless technology to enhance the features of their systems. Let’s take a look at each and see what is currently available.

As previously mentioned, one type of wireless security solution is the wireless security alarm system. There are two big advantages to using a wireless alarm system. First, the system itself is easy to install and operate. Second, aesthetically speaking, a wireless alarm is much more pleasing to the eye because it doesn’t require that a wire be run from each and every sensor to the master control panel.

Wireless alarm systems can be used for just about any application anywhere. A basic residential alarm system typically has door and window sensors on any readily accessible door or window (usually those above the second floor are not armed with sensors due to their inaccessibility). In addition, the system may utilize one or more motion detectors as well.

Each of these devices must communicate with the master control panel. They use this line of communication to tell the control panel that something has occurred (an event) and that their internal mechanism (usually some sort of switch) has been activated (triggered). Each sensor in an alarm system must have a separate transmitting wire that is run to the master control panel.

Wireless security solutions for alarm systems eliminate the need for this wire. Instead, each sensor usually has its own on-board power (a battery) and transmitter in addition to the switching device that is used to detect an event. When a trigger activates the sensors switch, the transmitter is turned on and sends a signal to the master control panel to initiate the alarm.

These sensors, including their batteries and transmitters can be quite small. The manufacturers take advantage of the latest electronic technology so the entire circuit to run the switching mechanism and transmit the signal can be created on an Integrated Circuit (IC) chip less than an inch in size.

The other major type of wireless security solution is a wireless digital video security system. Technological advances in these systems has taken leaps and bounds, compared to the original, bulky, analog parent cameras. In addition, the with the advent of digital video, the digital video security camera industry has been able to reap the constantly improving benefits produced by the computer and cell phone industries as well.

A typical digital video security camera system has three components. The camera or cameras capture video light images and transform them into electrical images. These images are part of a digital video file that is created by a Digital Signal Processor or DSP that accompanies the Digital Video Recorder unit or DVR. The digital file can be viewed live or at some later time on the monitor.

There are basically two different types of wireless digital video security systems. Both systems involve using radio waves to send their signals wirelessly but each type uses a different technology.

The first digital wireless security solution is the use of wireless digital video cameras. These cameras are no different than their “wired” counterparts accept they do not require a video transmission cable (usually RG-59 coaxial cable) to be run from each camera to the DVR unit. Instead, they send their data which is digital, in radio wave form either to a receiver that is connected to a DVR or to a wireless DVR that has a receiver built in.

The second digital wireless security solution is the use of wireless digital video cameras call Internet Protocol or IP ready cameras. These cameras contain on-board circuitry to not only capture and create digital data, but to transmit it in the form of a file that can be sent long distances using the Internet as the vehicle for networking. These cameras usually contain their own web server technology and transmit using WiFi technology.

So, as you can see there is a lot to talk about concerning wireless security solutions. If you are interested in a specific technology, check Security Camera King’s CCTV Learning Center for more information.

Camera Surveillance System Features

Written By:
Monday, September 27th, 2010

If you are looking for a digital video security and surveillance system, you should be aware of the more common camera security system features. Recent advances in digital video camera technology, digital video processing technology, and digital video storage capacities have provided an abundance of useful features and options.

Today’s camera security system features allow the user to have a complete standalone system, a system that can work using a personal computer to replace some of the components of the system (usually resulting in a less expensive system), or a system that can be remotely viewed and controlled via the internet. In addition, most contemporary security camera systems are component systems; that is, the individual parts of the system can be mixed and matched without regard to type or manufacturer with relative ease so the user can create a custom designed system to suit their needs.

Today a typical digital video camera security system features one to several cameras, a processor/Digital Video Recorder or DVR, and a monitor. Let’s examine the camera security system features by looking at the two main components; digital video cameras and processor/DVRs.

Digital Video Cameras
These cameras have a variety of options or features including:
• Specifically made for indoor or outdoor use
• Wireless technology, eliminating the need for a video transmission cable
• Powered by rechargeable batteries (this feature combined with wireless transmission technology makes these cameras truly wireless)
• Light Sensitive Day/Night vision that can produce high quality video images in very low light conditions
• Night vision infrared that can produce high quality black and white video images in total darkness
• Audio recording
• Pan-Tilt-Zoom (PTZ) functions-combined with software or circuit programming these cameras can “track” or “follow” objects
• Motion activated-these cameras do not begin capturing images until a motion detector senses movement
• IP (Internet Protocol) Ready-these cameras have their own built in server and can be networked using the internet
• Hidden or Disguised Covert Cameras-these cameras are so small they can be easily hidden in other objects or the cameras are built already embedded or disguised within other objects

Processors/DVRs
The processor/DVR handles several tasks and is the “brain” of the system. The processor handles the digital video signals sent by the cameras and uses a COmpression/DECompression or CODEC utility to make the digital video files easier to handle. It may also handle other functions like motion detection or PTZ controls. Finally, the DVR is equivalent to a personal computer’s hard disk drive. It stores the digital video files for archiving or later use.

One of the main features of this unit is the number of channels or cameras it can handle at once. Most units offer 4, 8, or 16 channel capability.

Camera security system features for the processors used today offer a variety of different CODEC utilities. There are many other choices for CODEC utilities includingH.264, MPG1 H.26 to MPG4, MOV, and DIV to name a few.

The DVR’s main feature is its storage capacity. Currently DVRs can be purchased that have storage capacities ranging from Gigabytes to Terabytes. As computer hard drive technology increases, storage capacity seems to increase and price usually decreases.

The processor/DVR unit is much like the case of a desktop computer. In addition to the features already mentioned these units may have additional bays or slots to add additional PCI cards or hardware. Common optional features of this type include CD/DVD writers or Flash Card writers that can copy the digital video files from the DVR to more portable media. This is useful for providing the video to police, insurance agencies, etc. or simply for archiving.

Another camera security system feature for the processor/DVR is a computer PCI card that works as a processor/DVR or utilizes a typical personal computer as the processor/DVR. This feature is great for residences because it normally reduces the cost of the system considerably.

As you can see, there are many different camera security system features existing today. This should give you a good working knowledge of the most common features that are available for your use and that will allow you to design your own custom component system.
