The Vitamin Decoder 2.1 is used to connect to many popular DLink and Vivotek models, such as the DCS-2000,2100 and 3220, as well as the 4XEM MPEG4 cameras. Private IPs are good for a LAN. Home » Blog » About Technology » Understanding IP Camera Specifications, What’s Important, This article was updated on 4/12/2018 to reflect new IP cameras. 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. 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. Yes, there are a few applications where you want higher frame rate, such as in gambling casinos, or in special testing situations, where you need to see very fast motion, but in most cases, you can save bandwidth and storage by reducing the frame rate. Lenses can have a fixed focus (that canât be changed), manual focus or auto-focus. This is a very nice feature that makes installation much easier. The fields were interlaced, so we wouldnât see the flicker. Once you know the distance and field of view, you can select the right lens. There are many things that are need for an IP camera setup. The smaller the iris opening the longer the depth of field. It depends on what you think is an acceptable image. This specification comes from the video broadcast market rather than the security market and can be totally confusing. The low light level image you see is not only dark but can also be very noisy. Each field had half the number of lines. The video is very smooth even at 10 fps. DVR/NVR tend to use a bit more than CCTV security camera or PoE security camera. The better manufacturers also include the relative level of the signal (IRE), which is a measure of how hard the amplifier has to work. Planning. With a PoE IP camera switch, you only need to plug the Ethernet cable of all the cameras with PoE into the switch, connect the PoE switch to the router, and then power the system up. See IP camera. The resolution of a camera is defined not only by the sensor, but also the lighting, lens and the electronic circuits. In the old days, the resolution was measured in TV lines, and they used a TV test pattern to analyze the resolution. The resolution of IP cameras is measured in Megapixels. 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. I moved this specification to this section because these days frame rates are not critical in most applications. 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. We have a lot of experience with IP security systems, so Iâm sure we can be helpful. 75 ohm coax cable. When the iris is closed all the way, it can reduce the clarity of the image (when used with megapixel cameras). Installation Requirements. Back in the old days, TV had only 525 horizontal scan lines per frame. 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. 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). Many of them with PTZ support. IP cameras don’t require professional installation, saving time for home and business owners. IR light can bend at a different angle than visible light when the wrong type of glass is used in the lens. CCTV Power Supplies / Battery Packs / Converters and much more. The total number of horizontal lines in a frame was made up of two fields (262.5 lines per field). For example, a 1.2 Megapixel sensor on the Sony SNC-EM600 camera has 1280 horizontal pixels and 1024 vertical pixels. 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 aspect ratio (vertical to horizontal ratio) is usually 4:3 or 9:16 (wide). 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. The minimum illumination is the lowest light level that provides a reasonable image from the IP camera. Most megapixel cameras support reasonably good frame rates. Planning before installing a CCTV camera. This discourages them from purchasing one, preventing them the security they require. There is some difference between the definitions of the television industry and the security market. 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. This means some areas that are close or far away are not in focus. CCTV Camera Housings. It is a good idea to draw a floor plan with camera locations, this will help you in deciding … PC requirements for 3-1. contrast 4-5. General Specifications a. This translates to a maximum frame rate of 2 fps. The sensor may have the megapixels, but the lens may be plastic, and the result is a very low-quality image. CCTV Mounting Brackets. Before reviewing the specifications, make sure you know your application and objectives. Many IP cameras come with a lens. The angle of the lens depends on the size of the sensor and the distance from the sensor to the lens. On the other hand, when the view is very dark, the camera tries to open the iris to let in as much light as possible. 2) Is compatible with encoder integral to IP camera. Today the cameras and displays (monitors and TVs) have a single progressive frame that includes all the lines (pixels) at one time. IP Camera manufacturers provide product specification sheets that help you select the right camera for your IP security and surveillance system. You also will require audio in applications like police interrogation rooms. 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. The focus can be adjusted at the computer, instead of at the camera. Many consumers find the need for a professional IP based security camera system for their home, business, or property, but are under the assumption that IP systems are complicated and too tech-heavy. âBack focusâ is not part of the lens, but is usually listed with the lens specification. This is called the signal to noise (S/N) ratio. For a more practical guide to how IP cameras perform at low light, take a look at our âIP Camera Low Light Testâ which compared a number of IP cameras at low light levels. If you increase the shutter speed to 0.5 seconds, the maximum frame rate is only 2 fps. You do get what you pay for. The most important aspect of installing a CCTV camera … The longer the shutter is opened the more light can reach the sensor. But, which specifications are important? A variable lens can be manually adjusted through a range of angles. The zoom lens is similar to the variable lens, but it can be controlled remotely. The importance of each of the camera specifications depends on your objective and application for your IP camera system. 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. It has to do with the pixel size. At the low light level, the amplifiers are working very hard and there can be circuit noise that affects the video image. The âpâ indicates “progressive” rather than “interlaced.” The older TVs used two interlaced fields to make one frame. This is most apparent at the higher resolution. We use cookies to provide the best browsing experience. What is reasonable? 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. By using our website you accept our use of cookies. 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. HD IP CAMERA SYSTEM MATERIAL SPECIFICATION . In the old days, people said you needed at least 30 fps. Be careful. Audio capability can be very important in some applications. D. DHCP, obtaining IP address through 3-1. The lens also can affect some of the other specifications such as minimum illumination, frame rate, and resolution. You can also select a camera with a built-in microphone, but be careful because itâs always best to have the microphone close to the person talking. 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. Well, it depends on the application. Getting Started Minimum System Requirements Fax Number: 914-944-0717, Copyright © 2020 Kintronics, Inc | All rights reserved |, Integration of IP Cameras and Door Access Control and more, Smartphone Door Access Using Bluetooth Reader, White paper: Video Management Software for IP Cameras, Calculating the Wire Gauge for Power to Your Device.

There are a few components that you will need to be able to install this type of security camera system. We are an engineering and consultation company that sells complete IP security solutions at the very best prices. If the IP camera doesnât include a lens, it usually includes a standard type CS (or C) mounting capability, so you can use various third party lenses. IR Corrected Lenses: Lenses bend the light to achieve the right focus and magnification. Today resolution is defined by the total number of pixels in the sensor or the horizontal and vertical pixels. For further setup and detailed feature descriptions, please refer to the user's manual on the software CD. The Sony 4K IP camera has a chip with 4096 H à 2160 V pixels which run at up to 60 fps and conforms to the Digital Cinema Initiative. The DC auto Iris lens is usually used with outdoor cameras. This is a list of relevant British, European and International standards for installers and maintainers of surveillance cameras. accessing 4-5. description 4-2. displaying 4-2. connecting, to the IP camera. H. help, for IP camera windows 4-2. For example, if you want to use the camera outdoors where it can get dark, then the low light specification is important. As the iris increases the depth of field is reduced. However, if not it’s almost certainly better to get a professional to do it. These two factors are a big part of why IP camera systems have become drastically more popular over the last few years. 2. For example, frame rates tend to be lower in very high-resolution cameras (over 3 Megapixel). The aspect ratio is 1280/1024 which is 1.24 or close to the 4/3 ratio (1.3). The lower the number the wider the viewing angle. IR corrected lens compensates for the focal difference and provides a much clearer image. The biggest problem with IP camera is to understand how it works, this step by step approach explains how to install an IP camera. Iris: Iris control adjusts how much light falls on the sensor. If you’re looking to save money and are reasonably technical then it can be done. If you are only using the IP camera indoors, you may be more interested in the how wide a viewing angle you can achieve. The lower the f-number of the lens the more light it will let through. The minimum light level is also affected by the shutter speed, which relates to the frame rate. It can be very confusing. It provides Plug & Play Ease of Use. 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. The frame rate can also be affected by very low light situations. It has approximately 4,000 horizontal pixels. Here’s what each of the terms means: Megapixel Camera: This i… By increasing the time that the shutter stays open, you can improve the low light performance of most cameras. When the scene is very dark the lens iris opens and the field of view is reduced. The minimum illumination level is also determined by the lens. Once you have holes drilled for your cameras, it’s time to … for the first time 3-1. For IP cameras: IP camera with Power over Ethernet (POE) feature. You don’t need to worry about the things you require for the setup of IP camera. The first step is to identify the location and the purpose of the camera. The installation time makes a big difference in the total cost of an IP camera system installation. Lens light capability: The f-number of the lens indicates how well the light is transferred through the lens. Required Bandwidth = 1 * 6144 kbps + 1 * 1024 kbps =7168 kbps = 7.168 Mbps. The 2 megapixel Samsung SND-6084 dome camera has 1920 x 1080 pixels, and the aspect ratio is closer to 16:9. The wide dynamic range has been dramatically improved in the latest cameras. Today resolution is defined by the total number of pixels in the sensor or the horizontal and vertical pixels. 720p cameras usually have a sensor with at least 1.0 megapixels. Cat-6 Ethernet cable. There are many cameras that have over 1-megapixel resolution. The lens angle can affect the f-number, the wider the angle the more light can get in, so the illumination spec is usually measured at the widest lens angle (when a variable lens is included). Such as: CCTV Cable and Wire. Here is a review of the important specifications. 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. Understanding the specifications, allows you to select the right camera for your IP camera system. Solution 3: IP Camera with PoE – NVR – Router. In the old days, the resolution was measured in TV lines, and they used a TV test pattern to analyze the resolution. Combining low-light monitoring capabilities and high-definition recognition, Hikvision smart IP cameras can easily meet the requirements of enterprise projects. Run Cables to Each Camera Location. A P-iris camera system works with the camera electronics to prevent the iris from closing all the way. For example, when you view a lobby with a large window, you will need a camera that either provides backlight control or better yet WDR. The 1080p HD camera has at least 1080 vertical pixels (or horizontal lines). Check out our short guide below to help you with your choice. 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 thatâs far away. Thinking about installing a CCTV system yourself? Pixel resolution is 1280 x 1024 (like the Sony SNC-EM600 1.3 megapixel camera), or it can be 1280 x 800 (like the Axis M3004 1.0 megapixel camera). The f-number will also appear as part of the minimum illumination spec. The Arecont 10 Megapixel cameras support frame rates up to 7 fps, which isnât too bad for most applications. For example, Axis introduced a camera with 3840 x 2160 which runs at up to 30 fps (which they called Ultra HD). We review the packaging, remote setup capability, and software management tools that reduce the time to install your IP camera system. P-Iris lenses are similar to the DC auto iris lens, except they add additional intelligence to the lens opening. When you are trying to view an area with challenging lighting conditions itâs best to select a camera that provides a good wide dynamic range (WDR). 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. The number of vertical and horizontal pixels and the aspect ratio are defined differently. Ensure High Definition IP Camera System is compatible with existing architecture and conforms to the following specifications: A. This quick installation guide briefly explains the installation procedure as well as some basic configurations of VIVOTEK VAST central management software. Camera specifications such as resolution, low light sensitivity, and the lens are some of the important factors to consider when selecting your camera. The IP address of a network camera is a private IP. Contact our support if you prefer a special camera type. 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. NETWORK IP SYSTEMS IP cameras use digital video transmission over CAT5 or CAT6 cable. The marketing people call all these cameras “4K”. In many cases you donât have to pay more for this capability, you just have to select the right camera. 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 Hanwha (Samsung) PNO-9080R has a resolution of 4000 x 3000 pixels. Marketing people also use the term “HD” and “720p” or “1080p”, and most recently “4K”. The lens allows you to frame the area that you want to see. In this case, you need a camera with audio input capability. Does DVR/NVR Use a Lot of Electricity. Resolution. Camera Video & Control window. Home window. There are fixed lenses, variable, and zoom lenses. Marketing people also use the term âHDâ and â720pâ or â1080pâ, and most recently â4Kâ. Either system can have recording capability, but the equipment will be different. This is not the actual resolution, but rather physical scans of an electron beam on a CRT (Cathode Ray Tube). If you plan to use a megapixel IP camera system, then make sure you get the IR type lens. The lower the IRE number, the harder the amplifier has to work to boost the signal so it can be seen. This can be very subjective. That, of course, is not true in most applications. This means that Hikvision equipment can be easily tailored to your budget and requirements, leaving you with a security system that suits your business. More cameras will follow in the next updates. WDR is measured in dB. Sometimes the specs are confusing, so always check with us if you have questions. In most cases you run your video and power to and from the camera on the same CAT5 or CAT6 wire, assuming you are using a POE (Power Over Ethernet) power source such as … Lenses.
