For more about IP Camera Resolution take a look at our blog article. When the scene is very dark the lens iris opens and the field of view is reduced. As the iris increases the depth of field is reduced. The Hikvision IP camera lenses have a wider coverage, so whilst they are more expensive than standard CCTV cameras, you will need to purchase less of them to cover the same area. Thinking about installing a CCTV system yourself? 2) Is compatible with encoder integral to IP camera. General 1. 2. This is called the signal to noise (S/N) ratio. The most common range is -, followed by - Lens light capability:  The f-number of the lens indicates how well the light is transferred through the lens. This is most apparent at the higher resolution. The iris affects the depth of field. If the IP camera doesn’t include a lens, it usually includes a standard type CS (or C) mounting capability, so you can use various third party lenses. We review the packaging, remote setup capability, and software management tools that reduce the time to install your IP camera system. TV / monitor with composite video input. IP cameras don’t require professional installation, saving time for home and business owners. Private IPs are good for a LAN. The 2 megapixel Samsung SND-6084 dome camera has 1920 x 1080 pixels, and the aspect ratio is closer to 16:9. Many of them with PTZ support. That, of course, is not true in most applications. For example, a camera that is operating at 30 IRE is receiving 30 percent of the signal from the sensor circuits, while one operating at 50 IRE is receiving 50 % of the signal. The first step is to identify the location and the purpose of the camera. Resolution. The latest sensors (especially the ones that claim 4K resolution) have different aspect ratios that are similar to the very wide formats used in the cinema market. Pro Series (EasyIP) Hikvision Pro Series network cameras aim to provide just the right components, including intelligent features that are affordable and easy to use. The sensor may have the megapixels, but the lens may be plastic, and the result is a very low-quality image. There are many cameras that have over 1-megapixel resolution. 4K Camera:  This usually refers to a camera with over 8 Megapixels of resolution. Most megapixel cameras support reasonably good frame rates. A manual iris lens is usually used with indoor cameras where there is a small light variation. There are quite a few types of IP cameras in the market and we have taken one of the best selling generic IP camera and software. Lenses. For example, a wide-angle lens could be used to view a small room, while a narrow-angle lens (with more magnification) can be used to see an area that’s far away. Camera specifications such as resolution, low light sensitivity, and the lens are some of the important factors to consider when selecting your camera. IP Camera Bandwidth Requirement. For example, Axis introduced a camera with 3840 x 2160 which runs at up to 30 fps (which they called Ultra HD). The marketing people call all these cameras “4K”. Since the bandwidth calculation of IP cameras would be too overwhelming, you can view the below IP camera bandwidth chart to see the overall Internet speed needed by your security IP cameras.

The longer the shutter stays open, the lower the frame rate. The IP address of a network camera is a private IP. There are some camera specs that indicate very low minimum illumination (0.0001 lux), but this is measured at a shutter speed of 0.5 sec. Today resolution is defined by the total number of pixels in the sensor or the horizontal and vertical pixels. You also will require audio in applications like police interrogation rooms. Once you have holes drilled for your cameras, it’s time to … There are fixed lenses, variable, and zoom lenses. A P-iris camera system works with the camera electronics to prevent the iris from closing all the way. This is an important specification. 720p cameras usually have a sensor with at least 1.0 megapixels. You do get what you pay for. It can be very confusing. At night it opens the iris and when there is bright sunlight it closes the iris. But, be careful. Camera Video & Control window. F. factory reset 4-4. Ethernet switch with POE output. We sometimes see megapixel IP cameras selling for under $200. This is a very nice feature that makes installation much easier. The lower the number the wider the viewing angle. The wide dynamic range has been dramatically improved in the latest cameras. For more details about this take a look at IP Camera Low Light Sensitivity blog article. The f-number will also appear as part of the minimum illumination spec. The minimum light level is also affected by the shutter speed, which relates to the frame rate. WDR is measured in dB. This is an important specification. General Specifications a. This means that Hikvision equipment can be easily tailored to your budget and requirements, leaving you with a security system that suits your business.

A 2 mm lens may have an angle of about 110 degrees, while a 50 mm lens has an angle of about 5.5 degrees. The fields were interlaced, so we wouldn’t see the flicker. D. DHCP, obtaining IP address through 3-1. This translates to a maximum frame rate of 2 fps. Cat-6 Ethernet cable. There is some difference between the definitions of the television industry and the security market. Here’s what each of the terms means: Megapixel Camera: This i… Back in the old days, TV had only 525 horizontal scan lines per frame. It has to do with the pixel size. By using our website you accept our use of cookies. For example, if you want to use the camera outdoors where it can get dark, then the low light specification is important. It is very important to use PoE equipment that is compliant with 802.3af or 802.3at standards, which ensures correct power delivery to the cameras. The noise level can be as high as 20% of the signal so the resulting video can look very noisy when the signal level is very low. This means some areas that are close or far away are not in focus. Back there was not easy yet to find a wireless IP camera, but that was not a problem to design the surveillance system, you are going to see why later. The Arecont 10 Megapixel cameras support frame rates up to 7 fps, which isn’t too bad for most applications. When you are trying to view an area with challenging lighting conditions it’s best to select a camera that provides a good wide dynamic range (WDR). Understanding the specifications, allows you to select the right camera for your IP camera system. The aspect ratio (vertical to horizontal ratio) is usually 4:3 or 9:16 (wide). There are a few components that you will need to be able to install this type of security camera system. USA Phone: 1-800-431-1658 The most important aspect of installing a CCTV camera … This specification comes from the video broadcast market rather than the security market and can be totally confusing. If you increase the shutter speed to 0.5 seconds, the maximum frame rate is only 2 fps. To confuse us, some manufacturers specify their 3-megapixel or 5-megapixel camera as “1080P” as well. If you want to detect that a door has been opened and start recording video, then you will require an IO input connection to the camera. IR Corrected Lenses:  Lenses bend the light to achieve the right focus and magnification. Check out our short guide below to help you with your choice. Solution 3: IP Camera with PoE – NVR – Router. The pixels are organized in a matrix of horizontal and vertical pixels. The frame rate can also be affected by very low light situations. It provides Plug & Play Ease of Use.

In general, security cameras, either CCTV analog cameras or PoE IP security cameras, are not energy-consuming as other gadgets like computers or bread toasters; they only need a very little electricity to work. Finally another standard called IEEE 802.11n came out and kept the same 2.4 Ghz frequency but increased the speed from 54Mbps to 300Mbps and now the new computers and laptops could also use such standard. CCTV Mounting Brackets. By increasing the time that the shutter stays open, you can improve the low light performance of most cameras. The lens also can affect some of the other specifications such as minimum illumination, frame rate, and resolution. The traditional and well recognized type of IP Camera is the Pan and Tilt, which requires the user input to move the camera to wherever he wishes to look into. Be careful. IP cameras can be powered near the installation point with 12V DC adaptors, or can utilize PoE technology in the PoE switch that provides power and data from one convenient device and over one cable. For example, a 1.2 Megapixel sensor on the Sony SNC-EM600 camera has 1280 horizontal pixels and 1024 vertical pixels. If you plan to use a megapixel IP camera system, then make sure you get the IR type lens. This is a list of relevant British, European and International standards for installers and maintainers of surveillance cameras. In certain cases, the frame rate has to be reduced. But, which specifications are important? The longer the shutter is opened the more light can reach the sensor. The angle of the lens depends on the size of the sensor and the distance from the sensor to the lens. The lower the f-number of the lens the more light it will let through. You can also select a camera with a built-in microphone, but be careful because it’s always best to have the microphone close to the person talking. DVR/NVR tend to use a bit more than CCTV security camera or PoE security camera. This crossover of IP cameras to home use is partly due to the device’s self-installation.

Our team of security experts will help you learn how to install security cameras, including where to place the cameras, as well as overall installation tips. This article reviews the important camera specs, and how to avoid being fooled by specsmanship (from the marketing department). Kintronics provides everything you need to create a complete surveillance and security system. In many cases you don’t have to pay more for this capability, you just have to select the right camera. Planning. The 1080p HD camera has at least 1080 vertical pixels (or horizontal lines). The p-iris lens prevents the lens from opening all the way and compensates by increasing the camera amplification of the video signal. CCTV Power Supplies / Battery Packs / Converters and much more. Take a look at our video “How the Video camera Works” for more details about frame rates and how they have evolved from the old days of TV. A camera with an f-number of f1.2 can pass more light than one that has f2.0 lens. After identifying them, you can mount the camera and junction box, please note that some cameras may have a deep base for cable management, but this particular camera needs a junction box to hide cable connections like RJ45 connectors and power leads. It has approximately 4,000 horizontal pixels. Either system can have recording capability, but the equipment will be different. Once you know the distance and field of view, you can select the right lens. Here’s what each of the terms means: Megapixel Camera:  This is a general term used for any camera that has over 1 million pixels in the sensor. On the other hand, large businesses and commercial spaces, like malls, require high-resolution videos (i.e., 4K), many cameras, and professional applications to accommodate the installation and management of the cameras. Marketing people also use the term “HD” and “720p” or “1080p”, and most recently “4K”. The Hanwha (Samsung) PNO-9080R has a resolution of 4000 x 3000 pixels. Pole-mounting: Two metal straps (not included) Shielded Category 5 (or above) cabling with drain wire should be used for all outdoor wired Ethernet connections and should be grounded through the AC ground of the PoE. It depends on what you think is an acceptable image. IR light can bend at a different angle than visible light when the wrong type of glass is used in the lens. The focus of the IP camera can be adjusted either by manually adjusting the lens or by remotely adjusting the distance between the lens and the sensor (back focus). accessing 4-5. description 4-2. displaying 4-2. connecting, to the IP camera. The DC auto Iris lens is usually used with outdoor cameras. Well, it depends on the application. IP Camera manufacturers provide product specification sheets that help you select the right camera for your IP security and surveillance system. The low light level image you see is not only dark but can also be very noisy. The number of vertical and horizontal pixels and the aspect ratio are defined differently. International: 914-944-3425 The aspect ratio is 1280/1024 which is 1.24 or close to the 4/3 ratio (1.3). The lower the IRE number, the harder the amplifier has to work to boost the signal so it can be seen. Ensure that the camera: 1) Is a dome or positional type as specified in the contract. It is a good idea to draw a floor plan with camera locations, this will help you in deciding what type of cameras to buy. IP cameras are gaining in popularity for its high definition picture quality, they are not expensive as they were in the past, many CCTV installers have started using IP cameras. “Back focus” is not part of the lens, but is usually listed with the lens specification. It can be very confusing. The importance of each of the camera specifications depends on your objective and application for your IP camera system. Home window. The lens allows you to frame the area that you want to see. for the first time 3-1. 1080p cameras have at least a 2-megapixel sensor, and it is considered to be the higher resolution “HD camera”. In the old days, the resolution was measured in TV lines, and they used a TV test pattern to analyze the resolution.
