IP Network Camera


Network IP Camera, often referred to as IP-Surveillance for specific applications within security surveillance ,remote monitoring and Security Camera, is a system which gives users the ability to monitor and record video over an IP network (LAN/WAN/Internet)

Unlike analog video systems, network IP camera uses the network, rather than dedicated point-to-point cabling like Siamese, as the backbone for transporting information. The term network video refers to both the video and audio sources available throughout the system. In cable (Coax) a network IP camera (video application), digitized video streams are transferred to any location in the world via a wired or wireless IP network, enabling IP video monitoring and recording from anywhere on the world.

Remote accessibility
Access live video at anytime, from anywhere
You can access real-time video at any time from any computer anywhere. DVR Master Network IP cameras products provide an easy way to capture and distribute high quality video over any kind of IP network or the Internet. The video can be stored at remote locations for convenience and security, and the information can be transported over the LAN or Internet. This means that even companies with several offices across the world can make effective use of a network video solution for security surveillance and remote monitoring purposes.

Network IP camera can be used in an almost unlimited number of environments; however, most of its uses fall into one of the following two categories:

·                     IP Security surveillance
Network IP's advanced functionality makes it highly suited to the applications involved in security surveillance. The flexibility of digital technology enhances security personnel’s ability to protect people, property and assets. Such systems are therefore an especially attractive option for companies currently using CCTV.

·                     Remote monitoring
Network IP Camera gives users the ability to gather information at all key points of an operation and view it in real-time. This makes the technology ideal for monitoring equipment, people and places both locally and remotely.

Network IP Camera Overview









Selecting camera for Surveillance DVR environment is important as choosing the DVR itself. Choosing the right camera for the job will give you the desire performance and picture quality depend on the environment the camera is in. The environments are divided to number of categories. First question we need to answer is if the camera is an indoor or out door camera. Answering this question will eliminate half of the trouble. Second question we need to answer is the distant between the camera and the viewing object. If we need to focus on a entrance door from a 24Ft ceiling we cannot use a fix lens that exist in most dome and bullet camera, we will need to use a camera that have the capability to manually or remotely zoom on the object, for this kind of scenario we are usually use CCTV Box camera with suitable lens.

Understanding camera spec will let you make wise decision on selecting the right camera for your environment cameras. All the cameras listed meet and exceed the minimum standards for professional surveillance applications. A lot of this information is good to review but you really do not need to memorize it.


CCTV Camera Resolution (Picture Quality) 

All cameras performance and picture quality is based on the number of horizontal lines the chip in the camera provides. Called the lines of resolution or TVL which specified the quality of the video the camera can produce. The higher the TV lines of resolution are, the better the quality of the image the camera send to the DVR.


Standard Image Quality

380TVL  To 420TVL

High Image quality

420TVL To 480TVL

Very High Image Quality

480 TVL to 570TVL

The Lens (Optics)
Lenses (Optics) play an important role in the design of a CCTV system. Their primary function is to
collect reflected light from a scene and focus a clear, sharp image on the camera's imager. Typically, the more light that passes through a lens, the better the quality of the picture.

Selection of a lens is especially critical because it directly affects the size, shape, and sharpness of the image to be displayed on the imager. Factors such as distance from the scene, focal length, desired field of view, lighting and format affect the size and clarity of the image on the camera's imager.

Field of View
The field of view (FOV) is the actual picture size (height and width) produced by a specific lens. If the field of view is not suitable, you may consider using a different lens (wide angle, telephoto, etc.) to increase or decrease the field of view. Tables are available to calculate the proper imager size, lens and distance combination needed to produce a desired field of view. See page 92 of this catalog.

Camera lenses can be divided into two basic types: fixed focal and varifocal (or zoom). A fixed focal lens has a constant focal length, while a varifocal lens can change its focal length. Focal length is simply the distance from the optical center of the lens to a focal point near the back of the lens. This distance is written on the lens (in millimeters) and indicates the field of view produced by the lens (See figure 7)

Figure 7: Focal length.

Fixed focal length lenses are available in various wide, medium, and narrow fields of view. A lens with a "normal" focal length (Ex: 8.0mm on a 1/3" camera) produces a picture that approximates the field of view produced by the human eye. A wide-angle lens has a short focal length, while a telephoto lens has a long focal length (See figure 8). When you select a fixed lens for a particular field of view, bear in mind that if you want to change the field of view, you must change the lens.

Figure 8: Wide angle vs. telephoto.

When both wide scenes and close-up views are needed, a varifocal or zoom lens is best. A zoom lens is an assembly of lens elements that move to change the focal length from a wide angle to telephoto while maintaining focus on the camera's imager. This permits you to change the field of view between narrow, medium, and wide angles, all on one lens.

The ability of a lens to gather light depends on the relationship between the lens opening (aperture) and the focal length. This relationship is symbolized by the letter f, which is commonly referred to as the "F-stop," and can be found printed on the side or front of the lens (see figure 9). The lower the F-stop number, the larger the maximum lens aperture and the greater the lens' ability to pass light through to the camera's imager.

For example, a lens with an F-stop of f/1.2 can gather a great deal more light than a lens with an F-stop of f/4.0. A lens with a low F-stop number is called a "fast" lens

Figure 9: The F-stop indicates the lens' light gathering ability.

Depth of Field
Another consideration when determining the proper lens is depth of field. Depth of field is the area in focus before and behind a subject (see figure 10). This means that when you focus precisely on a subject, a certain distance in front of and behind the subject also will be in focus, although not as sharp. Depth of field increases or decreases based on the 1.) Length of the lens, 2.) The lens aperture and 3.) Distance from the camera to the subject.

Figure 10: Depth of field.

Each of the three depth of field factors will yield the following:

 1) Lens length

Short lens (i.e. wide angle)

= longer depth of field

Long lens (i.e. telephoto)

= shorter depth of field

 2) Aperture

Wide aperture (low F-stop)

= shorter depth of field

Narrow aperture (high F-stop)

= longer depth of field

 3) Distance to subject

Short distance

= shorter depth of field

Long distance

= longer depth of field

Purchasing and planning decisions should take these factors into account since depth of field can affect image quality (and may jeopardize the ability to identify and prosecute subjects). If depth of field is important, you may want to explore options such as increasing artificial lighting or installing cameras with normal lenses rather than telephoto lenses, etc.

Lens Mounts
Camera lenses generally come with either a C-mount or CS-mount and must be matched appropriately to the camera's mounting requirements. The difference between the two mounts is the distance of the lens optics from the camera imager. The C-mount lens is 17.5mm from the imager; the CS-mount lens is 12.5mm from the imager.
