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 â1080Pâ 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. The âpâ indicates “progressive” rather than “interlaced.” The older TVs used two interlaced fields to make one frame. PC requirements for 3-1. contrast 4-5. Planning before installing a CCTV camera. Getting Started Minimum System Requirements Security Camera H.VIEW 5MP IP Camera with 2.8mm Lens Super HD Dome POE Outdoor Camera, Audio, H.265, Motion Detection, Smart IR, Easy Setup, Easy Install 4.0 … The relationship between the horizontal and vertical pixels is called the aspect ratio. 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 itâs 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. Contact our support if you prefer a special camera type. IP cameras are Digital and connect via Cat5 (Networking) Cable or WiFi. If you plan to release a door lock, you need an output signal to control a relay that can open an electric lock. Transmission 36 4.1 Wired Transmission 36 4.2 Wireless Transmission 39 4.3 IP Network Transmission 42 5. The better manufacturers also include the relative level of the signal (IRE), which is a measure of how hard the amplifier has to work. 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 donât 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 âHow the Video camera Worksâ 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. Hereâs 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 âHDâ and â720pâ or â1080pâ, and most recently â4Kâ. 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. âBack focusâ is not part of the lens, but is usually listed with the lens specification.

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 âHD cameraâ. In the old days, the resolution was measured in TV lines, and they used a TV test pattern to analyze the resolution.
