Outdoor Exterior Security Camera Software

In this article we are going to talk about outdoor exterior security camera software. We’ll talk a little about what it is and how it works and what type of outdoor security camera equipment you can use with it.

So exactly what is outdoor exterior security camera software? There are basically two types of software. The first type is software that is used on a standalone digital video security camera system and the second type is software that is used with outdoor exterior security cameras and your personal computer. Although the name “outdoor exterior security camera software” refers to a computer based program, both types serve different roles in a digital video security camera system.

The first type of outdoor exterior security camera software that we refer to is used with a standalone digital video security camera system. These systems normally consist of one to several cameras, a Digital Video Recorder or DVR with a Digital Signal Processor or DSP, and a monitor. The outdoor exterior cameras capture the video image and send it in digital form to the DVR unit that includes the DSP. The DSP interprets the digital data and uses a special program utility, called a COmpression/DECompression or CODEC to create a digital video file. The digital video file is stored on the DVR and can be viewed on the monitor in real-time (live) or at a later time.

The outdoor exterior security camera software in this case is used on the DVR with the DSP to coordinate each component in the standalone system and provide any additional camera, DVR, or monitor functions. For example, outdoor exterior security camera systems are often used in commercial settings such as providing security in store parking lots. In this example the software coordinates the functions of the cameras with the DVR and DSP, may provide the programming necessary for the CODEC that is used, and directs the DVR to store the digital video file that is created.

In addition, this particular outdoor exterior security camera software may also include special functions that either operate or control the camera, DVR, and monitor. A specific example of this type of software is often used in the store parking lots already mentioned. In this setting, it may be advantageous for the user to follow or “track” a person or vehicle. Pan-Tilt-Zoom (PTZ) cameras used with DVRs that have software with this capability can detect motion. Once the motion is detected (by the software programming) the camera is controlled by the software to Pan, Tilt, or Zoom in order to provide the best possible video of the object as it moves in the field of vision of the camera. Usually, this software is provided by the manufacturer of the DVR at the time of purchase of the unit.

The second type of outdoor exterior security camera software that we mentioned earlier is used with cameras and a personal computer. Although this software may be able to perform the same functions as the standalone security system, it has an additional responsibility of coordinating the digital video cameras with the computer. In these systems the personal computer takes the place of the DVR and DSP as well as the monitor.

These systems are advantageous because they enable the use of an existing personal computer with the digital security cameras. The computer is connected to the cameras via a PCI type computer card that serves as the bridge between the two. Ultimately, for just the cost of the digital video cameras and outdoor exterior security camera software and PCI card, an entire digital video security system can be constructed without the need to purchase a DVR and monitor.

Since computer and electronic technology is rapidly advancing, there may be a third type of outdoor exterior security camera software to consider as well. Although this system uses components that are not specifically designed as digital video security equipment, it may make an economical suitable substitution in some instances. This third type of software allows the use of a webcam or other similar device to be used as a security camera.

This should give you with some good introductory working knowledge about outdoor exterior security camera software. There are as many different brands of software as there are manufacturers of equipment; too many in fact to mention in this article.

Camera Surveillance System Features

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.
