That camera? best to monitor?

We send all data / images / illustrations referred to in this article, click here. BSTRACT / strong> Looking for a digital camera for use in performance monitoring? Well, technological improvements in CCD and CMOS image sensors, as well? the introduction of new high-definition playback and recording formats have certainly led to the introduction of many different models of digital cameras. Due to the large differences in features and price,? pi? harder than ever to select the best digital camera. Certainly, some models are better than others because of the specific application for which? for the camera and the functions needed. Why? There are true? many factors involved in making a selection, and since the new models are often introduced? best to provide guidance when considering designs for a specific application. Then, when the new models are available, you? compared with current models based on the guidelines. The purpose of this work? to establish guidelines that must be considered when evaluating cameras for surveillance applications. These applications are used by military, police and special investigative services staff to gather evidence or Electronic News Gathering and races usually include remote viewing. Although these helpful guidelines for understanding the specific camera importantly, before you purchase decision camcorder, you need to carry out its own research models available and based on these guidelines, select models that are designed to offer the best performance and number of tests to do in real life situations. You? Learning that other factors may be important for your specific application and that the final decision? a compromise of these other factors. Monitoring the quality Optical image? of paramount importance. Camera sensitivity and resolution? factors are the primary treatment, with a variety? related factors such as image pixels and field-of-view, pixel size, as well? the tariff structure stabilization photos, options and alternatives interchangeable lenses? objective of integration ‘mode?, digital zoom and resolution display screen, user interface, video formats, recording media, Manual Gain fashion? infrared, video compression, external audio inputs, viewfinder, robustness and video compression. Camcorders resolution The video resolution? working? influenced by a variety? various features of the camera. And know that the high-definition camcorders a higher resolution than standard definition format to deliver. Right? important to realize that if your camcorder You to sequences of images that follow (record instead? use the camera for viewing the video output in real time) and the optical resolution and the recording format to be seen in To be decided on the final solution. individually, the optical resolution is not only dependent on the size detector array, but also the image pixel and vision. HD recording format also affects the resolution. Finally, there are other factors that may deserve a resolution reflecting the ultimate resolution camera to determine. Detector Array Size: It seems that every camera has a slightly different imaging detector. Although the format of HD recording to? are 1280×720, 1440×1080, or 1920×1080, imaging detectors can vary? run a bit. ” As shown in the table for a selection of mid-range cameras, the detector array size can vary? S single-chip cameras have arrays as large as 1920×1080 (Canon HF-10 and Sony HDRSR11) block of three chips with sensors so large as 1440×1080. The physical dimensions of the image detector varies from camcorder to camcorder. image pixels and the Field: /> p

As shown in the accompanying chart (see link above), the combination of physical size of the camera detector image (eg 1 / 3 “) and the focal distance of the target population (eg 50 mm) produce images View (FOV), defined as the angle from which the image information is received. There are different angles, which correspond to horizontal and vertical directions, depending on the aspect ratio image. For video formats in widescreen, the vertical? FOV 9 / 16 horizontal FOV. All cameras have zoom lenses where the focal length varies from one angle (the longest angular FOV) in a remote mode ( with the most? small angular FOV). The result is a small area in a higher magnification image, as would be required for viewing small objects at a distance. imaging detectors creating more small corner of the eye? limited when used with the same focal length lens. For example, a 50mm lens offers a horizontal field of view May 5.? and 3. 7? when using a 1 / 2 “and third” detector size, respectively. Based on changes in size of the detector and the focal length of the lens, the angular field of view of the cameras varies accordingly. The image FOV batch can be determined for each camera based on a simple formula. The GV-pixels (also known as the instantaneous field of view or IFOV)? a measure of the resolution of an imaging system. although related, pixels and FOV FOV are distinct and a narrow FOV camera with image need not be a narrow FOV pixels. As shown in the table ( see link above), while the Canon cameras have more? small image pixels and FOV values, the Sony HDR-SR11 has a small field of view FOV, despite a pixel image? almost two times more? wider than Canon. < / P> A handy calculator FOV can be used to set values for certain candidate FOV camera to set . Pixel FOV is calculated as the detection, identification and detection range of values for certain formats specified object to a certain distance. Recording Format: The difference between the various formats of HD recording? outside the scope of this document. However, the impact of the recording format of the resolution? essential to the performance of imaging techniques for surveillance applications and is described here. As shown in (reference: the first link article), standard definition camcorders (with an aspect ratio 4:3) recorded video with 480 horizontal lines per frame, giving a resolution of 640 x 480. (This? NTSC. PAL recorded with 576 lines per frame, giving a resolution of 640×576). the widescreen versions of these standard-definition camcorder with a 16:9 aspect ratio available and recorded with a resolution a little more? larger than 720 x 480 (720×576 for PAL versions). Given the limitations of recording format, it would not useful for a high resolution of a CCD / CMOS detector pi? large 720×480 pixels in NTSC standard definition video camera, except in certain circumstances (such as zooming in on the central pixel can be seen). However, with the introduction of high- resolution formats for recording, higher resolution detectors sense. Sensitivity camcorder High Definition video includes a higher resolution than standard definition and more? often refers to resolutions on the basis of either 720 lines per frame or 1080 lines / frame. Recording Formats Can 1920×1080, 1440×1080 and 1280×720. Consequently, there are at 720 or 1080 lines per frame recording formats with a resolution of 1280×720 and 1920×1080 , respectively. It is important to the recording format for each camera in question to understand. If the full resolution of the sensor? necessary for the monitoring function and to perform, ensuring that the camcorder records in sufficient resolution. If this was white paper on digital cameras, the debate over the recording format was sufficient to impact on the quality of the image to describe. However, given the videotaped movement, the fact that some “cameras “interlaced video, while other video recordings of the” progressive has some relevance, especially when the movement? important for the type of ongoing monitoring. Otherwise, the relevance of interlaced vs. progressive scan? less important. Other factors Resolution: It is worth remembering that in those three cameras sensors, the pixel-shift technology used operates in the horizontal axis to incremental improvements to the sensor resolution by interpolation. This complicates the calculation of the optical resolution a bit ‘, but can not? a primary factor. sensitivity? Camcorder mostly low-light? important for surveillance applications, especially when imaging at dusk or dawn, but even when accompanied by a form of night vision that intensifies ambient light. The guidelines for the evaluation camcorder are listed below. We recommend an examination of the following factors: Recommended Minimum Illumination Specification, Objective Lens F-number, detector pixel size, availability? the form of night vision. as such, but the criteria that allow the comparison of these, including: F-goal target number, pixel size, electronic noise? It is clear that the low-light performance, as indicated in the list of specific cameras because? different cameras can lead to different results, but the specifications may? comparable. Therefore, once you have you? An unidentified couple of different cameras that the features of interest and performance you need? strengthening the capacity to test? low brightness camera. Recommended Minimum illumination specification: Very often, low-light performance specifications are available on data sheet of the camera. These are usually described as “low sensitivity light” or “minimum illumination” and the result? expressed in lux. Pi? low? lux rating, the better? the camera performs in low brightness. However, since? Details describing how these measures are often made in low light? expected? extremely difficult to compare data in different models of camcorders from different manufacturers to compare. (What? The reflectivity? Taken objects seen?: What is the signal to noise ratio? Brightness screen? Etc..) As such, the use of these specifications? complicated and often unsatisfactory. And of course better to test yourself camcorder. Some websites (such as www. Camcorder Info. Com) to meet their rigorous testing. detector pixel Size: Not only the size of the detector array is important, but the physical size of the sensor? important for several reasons. Very often small scale detector (such as 1 / 6 “format) are in the less expensive cameras, while the larger detectors (eg 1 / 3″ format) are high-quality cameras. Smaller detectors are physically small, slow and result in less expensive compact cameras at low cost. For surveillance applications, an important consideration? which decreases the sensitivity? light in the pixel format. While large pixels, in general, have a sensitivity? pi? and slightly higher when the images in low light or at night, plus? pixels also result in lowering the resolution (especially in light of a focal length of the lens). Moreover, there are more? large pixel size of matrix array of outstanding achievement in large and large lenses. What?, More pixels? children are often preferred. You should compare the sensitivity? video with the most? small pixels with other cameras in question. pixel size for a range of digital cameras are shown in the table (reference: the first link in the article). Objective Objective F number: What SLR camera lens F-number? extremely important for a low sensitivity? light camera. All parity? other conditions, a lens with a low f-number (like F1. 4) focuses largely on the stage of light-sensitive imaging detector camera. A lens with a number of F-what? twice more? high (F2. 8) passer? only 25% of the light which the camera is 25% sensitive. This? a lot! For compact cameras with you? Integrated lenses, sometimes the “target must be designed with a relatively high number of F, in order to maintain the compact design and deliver the zoom range is desirable. In particular, we find that F-number increases at most? values of the focal length slightly. The numbers in the F-maximum zoom setting for a series of digital cameras are listed in the attached table. Night Vision Module Availability?: for the cameras used for surveillance applications, the availability? a form of night vision can? very important, particularly for imaging at a distance and at night. Cameras just do not have sufficient sensitivity? light for imaging in these environments. However, _blank enclosing a form of night blindness, as shown here , the sensitivity? light camera? F-stop be increased to ten. How? known, the resulting image Night vision? Green, the absence of all colors. But images can be quite? produced in the light of the stars and the moon. Some of these forms of night vision equipment you? See the link below. Factors others The assessment of cameras for surveillance applications, the resolution and sensitivity? Usually the main considerations, but other factors deserve attention. Some of these are listed below. Media: “Media” refers to the point where the video will be? stored. Many cameras use different types of media. The following species media and a number of considerations for surveillance applications: MiniDV Tape – These are used for many years. The downside? the need? fast forward and rewind instead of direct access. They are known as very reliable, are widely available and robust. Moreover? often useful to a physical medium with the images of the surveillance, rather than a soft copy could only have more? easily misplaced or mislabeled.

MiniDVD – Even as a family, can? not be profitable as expected after the DVD is often not included in the DVD player. Moreover, the inclusion of high quality has resulted in some capacity? significantly more? low.

Hard Disk Drive (HDD) – This is the average capacity? generally high (eg 120 GB) to record time-consuming. Backup? obviously important and necessary. Also note carefully whether compressed video is used for storage in order to increase capacity? available.

Flash Memory – flash memory (such as solid state memory and memory cards)? very interesting because there are no moving parts, resulting in a compact and efficient? nt. Capacity? are increasing each year.

Stabilizer: Image stabilization? functionality? video camera that improves the quality? picture during the video recordings by hand, which reduce blurring caused by camera shake. Stabilizer corrects camera directly as to shake the images freehand full telephoto (like the video taken from a car in motion) are regularly and consistently. This image stabilizers? optical or digital design. optical image stabilizer usually treated in a prism lens to the image projected on the camera sensor to stabilize. digital image stabilizer usually the feeling of movement and camera, using additional rows and columns? on the edge of the detector, moving the image of an appropriate amount for certain types of traffic to stabilize. Normally, optical image stabilizers, although most? expensive, are better because the better the fading part of the movement to abolish. interchangeability? Goal: Many camcorders cheap lenses are not removable. These lenses are compact and strong you? Integrated in the camera body, have a large zoom range and power? macros. Normally, the vision of you? Integrated zoom lens? selected to obtain the desired FOV range for most applications. However, for greater versatility?, High-end cameras have a removable lens and lens support so that a series of lenses? be offered for a change in pi? broader applications, including the most? a wide viewing angle and telephoto plus?. (See the list of mid-range cameras have removable transparent here). For non-interchangeable lens cameras, as the angle pi? wide or more? remote field values is required, the cards may be offered to increase as the desired change. But the result? a reduction in quality? optics. For monitoring videographer, interchangeable lenses? very useful if the magnification offered by fixed lens cameras can not? sufficient for the desired application. Moreover, the modules for night vision cameras that are designed to fit between the interchangeable lens and camera and keeps us all? objectively ‘features including motorized zoom, image stabilization and auto-iris. Digital Zoom: digital zoom? an important feature for each camera. Since? not? , all in the resolution imaging detector on the camera viewfinder or display value, digital zoom makes it possible to see details on the viewfinder that would otherwise go unnoticed until the digital images were then analyzed. Moreover? useful to a detector with an array of pixels pi note? large operator can perform the digital zoom more? that a camera with a sensor more? small, without the effects of pixelization. User Interface: Each camcorder operator to confirm? that accessibility? services? of some importance. Drilling already? through sub-menu after sub-menus to access features are not routine? a desirable thing to do while in the field. IR: Some cameras have sensitivity? near-infrared light by using an infrared spotlight for easing the sc? ne. For some reason, these lights do not apply to many situations supervision. First illuminators usually supplied with the cameras do not project enough light at a distance of interest. They can also be detected by others with more? CCD cameras and camcorders. Manual Gain: For low light, some cameras have a mode? Manual Gain allowing the user to manually adjust the gains in video image, usually rises to 18 dB. Although grainy surveillance applications, video-images are usually not present a significant improvement or even self-acquired versions. Speed? Shutter: To maintain the standard frame rate (eg 60 Hz) not? required because the objects under observation are not moving fast, the frame rate? and speed? shutter speed detector? be reduced (eg 1 / 3 sec), so each pixel is the integration of the sensor? more light on the periods? long that are exposed. In a dark environment, selecting the most? acceptable long integration can? enough to a usable image sunset or sunrise services. external audio inputs: To ensure the appearance of playing as a pure optical geek prevented? Remember that the audio quality and access to external audio inputs? important for video surveillance. The microphone is not always good at taking pictures away or if you need something more? directional filters out ambient noise. Viewfinder: If you are covert, with a viewfinder of the camcorder on again? important to the bright lights of the LCD panel to prevent. stability: Another serious danger? the lack of robustness in the camera hardware – switches and controls stress vulnerable because videographers. If you’re on the field in potentially dangerous conditions, not only wants to play with the controls and LCD panels that easily. Price: Of course, the price? always a consideration in assessing the patterns of many, many cameras available today. But how are these directives show? that very often, most camcorders? not expensive? the best for a particular question. Understand which features the most? useful for your application because the price of cameras. Conclusion technological improvements in CCD and CMOS image sensors, as well? the introduction of new high-definition playback and recording formats have led to the introduction of many different models of digital cameras. Guidance was provided in assessing applications for surveillance cameras. Monitoring the quality Optical image? of paramount importance. Camera resolution and sensitivity? are the main factors to consider, with a number of factors such as image and pixel of the image, the pixel size, so? as frame rate, image stabilization, alternative options and compatibility? slow slow integration mode?, digital zoom and resolution display, interface, video formats, recording media, have manual mode? infrared, video compression, external audio inputs, viewfinder, robustness and video compression.
