差距不止10ms 民用监控硬盘录像机横评
差距不止10ms 民用监控硬盘录像机横评也许你会诧异为什么评测硬盘录像机要以监控延时做参考，模拟监控系统打响了安防监控;;零延时;;口号，模拟监控延时能够判定处理速度是否给力。
从一名普通消费者角度出发，选购什么品牌的硬盘录像机才算好？录像机延时只是其中一点，关于画质，操纵还有更多对比。
老百姓讲求的就是个实在，花1000多块钱买个设备回家，就要物有所值。
第一关就得验证传输速度。
为了供大家多项选择，本次测试选择了海康威视DS-7808HW-SH、大华DH-DVR5104、蓝色星际BSR-8008N、汉邦高科7008KC四家不同厂商产品进行评测。
差距不止10ms民用监控硬盘录像机横评模拟监控：监控延时存差异网络监控系统存在延时是很正常的情况，那么作为传统的模拟系统，监控延时是否能够控制在理想数值呢？视频信号经过数模转换的确会花费一定时间，被业内称作;;零延时;;的硬盘录像机，在横向对比上不知能否取得好成绩。
我们对这四款硬盘录像机进行了延时测试，测试环境为局域网内，不存在网络传输及带宽问题，直连输出视频信号。
经系统运行稳定后抓拍了实时显示效果。
从下面张图可以看到，分别对应着上述硬盘录像机的延时时间，表现最好的是海康在0.1s~0.11s之间，其次是大华为0.11~0.16秒，其次是蓝色数据维持在0.16~0.2秒，汉邦表现略逊一筹，延时时间超过了0.2s以上。
海康威视DVR延时0.1s大华DVR延时0.16s蓝色星际DVR延时0.17秒汉邦高科DVR延时0.21虽然各款设备延时时间把控较合理，但是内部比较来看，仍存在较大的差异。
试想如果连接多路设备，延时时间是否更长，那么实时性效果将大打折扣。
当然，上述4款硬盘录像机的差距不仅局限在延时上，真正的差距也不只有10ms…大体积设备开机慢有人说系统越复杂，开机时间就越慢。
不知硬盘录像机是否也存在这样的问题。
从外观来看，4款录像机体积差异较大，以最小的大华硬盘录像机看似更适合民用领域，蓝色星际大体积录像机在连锁商铺上一定有用武之地。

波士顿安全DINION IP Starlight 8000 MP摄像头说明书
The DINION IP starlight 8000 MP camera provides clear images 24/7 – even at night or under low-light conditions.High sensitivity in color (0.022 lx at 5MP and even0.013 lx at 1080p) enables this camera to work with a minimum of ambient light. This exceptional light sensitivity combined with Content-Based Imaging Technology (C-BIT) ensures crisp, clear, detailed images in all lighting conditions.System overviewCompared to HD cameras, the DINION IPstarlight 8000 MP offers much higher resolution, best-in-class sensitivity, highest frame rates for MP camerasin the industry, and highly usable images even in low-light and HDR scenes. And yet the camera is bandwidth efficient due to the state-of-the-art sensor, the intelligent noise reduction and advanced compressor.FunctionsExceptional low-light performanceThe latest sensor technology combined with the sophisticated noise suppression results in a sensitivity of 0.022 lx at full 5MP resolution in color. The low-light performance. In IVA versions, the intelligent Automatic Exposure (iAE) technology, for example, allows you to view moving objects in bright and dark areas of a scene.iDNR reduces bandwidth and storage requirements The camera uses intelligent Dynamic Noise Reduction (iDNR) which actively analyzes the contents of a scene and reduces noise artifacts accordingly.The low-noise image and the efficient H.264 compression technology provide clear images while reducing bandwidth and storage by up to 30% compared to other H.264 cameras. This results inreduced-bandwidth streams that still retain a high image quality and smooth motion. The cameraprovides the most usable image possible by cleverly optimizing the detail-to-bandwidth ratio.Area-based encoding is another feature which reduces bandwidth. Compression parameters for up to eight user-definable regions can be set. This allowsuninteresting regions to be highly compressed, leaving more bandwidth for important parts of the scene.allows fast and easy configuration. Nine configurable user modes are provided with the best settings for a variety of applications:•Indoor – general day-to-night changes without sun highlights and street lighting (e.g. office environments)•Outdoor – general day-to-night changes with sun highlights and street lighting•Night optimized –optimized for sufficient details at low light (at the cost of a lower frame rate and more motion judder)•Low bit rate – optimized bandwidth (at the cost of reduced contrast, less detail and less sharpness)•Intelligent AE – optimized for scenes with moving objects against bright lights (this mode will switch to BLC if no IVA is available)•Vibrant – similar to Indoor mode with enhanced contrast, sharpness and saturation (at the cost of a higher bit rate and less details visible in darker areas)•Sports and Gambling – enhanced color and sharpness (for use in casinos)•Traffic – for monitoring traffic movement at roads,Cloud-based servicesThe camera supports time-based or alarm-based JPEG posting to four different accounts. These accounts can address FTP servers or cloud-based storage facilities (for example, Dropbox). Video clips or JPEG images can also be exported to these accounts.Alarms can be set up to trigger an e-mail or SMS notification so you are always aware of abnormal events.Access securityPassword protection with three levels and 802.1x authentication is supported. To secure Web browser access, use HTTPS with a SSL certificate stored in the camera. The video and audio communication channels can be independently AES encrypted with 128-bit keys by installing the optional encryption site plete viewing softwarelighting conditions.Easy installationPower for the camera can be supplied via a Power-over-Ethernet compliant network cable connection.With this configuration, only a single cable connection is required to view, power, and control the ing PoE makes installation easier and more cost-effective, as cameras do not require a local power source.The camera can also be supplied with power from +12 VDC power supplies. To increase system reliability, the camera can be simultaneously connected to both PoE and +12 VDC supplies.Additionally, uninterruptible power supplies (UPS) can be used, which will allow continuous operation, evenduring a power failure. For trouble free network cabling, the cameras support Auto-MDIX.Varifocal SR Megapixel LensRugged varifocal SR megapixel IR corrected lens.1/1.8” sensor; CS-mount; 4-pin SR-iris; 5MP;4.1 to 9 mm; F1.6 to F2.4Order number LVF-5005C-S4109AccessoriesMonitor Cable SMB 0.3MAnalog monitor cable SMB (female) to BNC (female).0.3 meterOrder number NBN-MCSMB-03MMonitor Cable SMB 3.0MAnalog monitor cable SMB (female) to BNC (male).3 meterRepresented by:Americas:Europe, Middle East, Africa:Asia-Pacific:China:America Latina:Bosch Security Systems, Inc. 130 Perinton Parkway Fairport, New York, 14450, USA Phone: +1 800 289 0096 Fax: +1 585 223 9180***********************.com Bosch Security Systems B.V.P.O.

The use of an intelligent DSP design eliminates push buttons and allows all programming to be done either via an integrated touch-screen or a mouse interface. In addition, IEEE-488, Ethernet, and USB interfaces have been added to extend remote operation capabilities. The display can be set for one of three display modes; 0-360º, ±180°, or Degrees, Minutes, Seconds. A wide (47 Hz to 20 KHz) frequency range is standard. As an option, a programmable 2.2 VA internal reference supply can be specified.Improved flexibility is provided by two fully independent inputs that can be used to simultaneously read two separate input signals or can be combined to measure multi-speed Synchros or Resolvers. The gear ratio, for the two-speed mode, is programmable from 2:1 to 255:1Built-in phase correction eliminates errors caused by quadrature and harmonics when reference and signal are out of phase by as much as 60°.The 8810A automatically accepts and displays input voltages from 1.0 to 90 V L-L and Reference voltages from 2 to 115 Vrms over a broad frequency range of 47 Hz to 20 KHz.Therefore, one Instrument can handle most known Synchro and Resolver measurement requirements.The 8810A is a direct replacement for all variations of the previously supplied North Atlantic Industries Model 8810.

Genelec 8351B 智能活动监控器操作手册说明书
8351BSmart Active Monitor Operating Manual2IntroductionThank you for choosing Genelec! Fulfilling your dreams by offering the most truthful sound reproduction has been the source of our enthusiasm since 1978. Already over one million Genelec monitors are in use around the world - welcome to our story!Genelec monitors are designed to last long our spare part support extends far into future. They are hand-built in Iisalmi, Finland, using certified sustainable methods. They are individually tested and calibrated for the highest performance. They have also all been designed for low power consumption in use and in standby.Please register your monitor atmunity. /and receive an extended five-year warranty for spare parts. For more information about our service and technical support, please visit/customer-service.System CharacteristicsEach 8351B is supplied with a mains power cable, five-meter GLM network cable and this operating manual. The Genelec 8351B is suitable for all professional monitoring applications calling for very high precision and reliability. The 8351B combines many remarkable Genelec technologies to provide the benefits of a point source and controlled directivity over an extraordinarily wide audio bandwidth. The 8351B may be oriented horizontally or vertically. Listening distances can vary from less than one meter to more than 4 meters, depending on the room size and maximum sound level requirements. Genelec Loudspeaker Manager™ (GLM™) Software and GLM User KitThe GLM software tailor-fits the 8351B to your room. It is downloadable free of charge at /glm. Check regularly for updates and new features, and consider using the cloud-based GLM services for the most up-to-date methods.A GLM User Kit, comprising a USB adapter device and measurement microphone, enables precise acoustic calibration and operation of the GLM loudspeaker management network.Minimum Diffraction Coaxial (MDC™)The minimum diffraction coaxial transducer MDC design implements a coaxial driver with unparalleled acoustic directivity control. A powerful midrange transducer surrounds a high output tweeter transducer, enabling a high resolution response extending to ultrasonic frequencies. The MDC minimizes acoustic diffraction, produces a flat frequency response on the acoustical axis, and a neutral off-axis sound character. Directivity Control Waveguide (DCW™) and Acoustically Concealed Woofers (ACW™) The 8351B has an exceptionally large Directivity Control Waveguide extending over the whole enclosure front. The midrange transducer cone forms a part of this DCW. Two woofers radiate low frequencies through openings at the enclosure edges and sum acoustically placing bass on the same acoustical axis with the coaxial transducer. This unique design enables directivity control of all audio down to low bass frequencies.Smart Active Monitoring (SAM™) Smart Active Monitors automatically tune several parametricfilters in themselves to precisely compensate for room colorations using Genelec Loudspeaker Manager (GLM) software. This enables SAM monitors to sound neutral and achieve precise stereo imaging in all acoustical environments, improving accuracy of monitoring.Audio InputsThe 8351B inputs support balanced analog line-level audio and AES/EBU digital audio. At maximum sensitivity, -6 dBu analog and -30 dBFS digital audio signals produce 100 dB SPL level at one meter distance in free space.The analog input is selected when a digital signal is not present. The digital input is selected automatically when a digital signal is present even when the signal is silent. The GLM software can select either input.When the digital audio source can adjust level, it is advantageous to lower the output level of the 8351B using the rear panel controls or the GLM Master Fader. This enables a higher output level at the source with more resolution while taking full advantage of the impressively low self-generated noise of the 8351B.An AES/EBU digital audio signal carries two channels in one cable. A channel is selected using the DIP switches or GLM software. The DIGITAL OUT carries an unaltered copy of the input, enabling daisy-chaining of up to four monitors.Power ManagementThe mains power input supports any mains voltage (100-240 VAC, 50-60 Hz) and the 8351B always delivers full power even when the mains voltage fluctuates. When powered with a generator, inverter or UPS device, we recommend filtering the mains power to remove harmonics.The energy saving function Intelligent Signal Sensing (ISS™) puts the monitor to power educed sleep mode when no signal is present. Upon sensing an input, the monitor wakes up. The function is activated using GLM software or the ISS dip switch on the monitor. With GLM the time before entering the sleep mode can be adjusted, the ISS dip switch activates a fixed 60 minute time.Setup Using The GLM™ Control Genelec recommends setting up the 8351B and other SAM monitors using GLM. This is described in the GLM System Operating Manual. Although it can be used without GLM and the network, the 8351B reaches its full potential with this method. GLM software runs on Mac or Windows computers. GLM also works as a monitor controller, for switching between sets of loudspeakers, soloing, muting, invoking calibrated levels, etc. Setup with the GLM User Kit consists of the following steps: 1. Connect a CAT5 (RJ45) cable to each monitor (and subwoofer) and finally to the GLM Adapter device (see Figure 1).2. Connect the GLM Adapter device to computer USB connector.3. Using a microphone stand, place the Genelec measurement microphone (in GLM Kit) at the listening location. Point microphone upwards. Place the microphone top at the ear3Figure 3. Connector panel detail.height for typical listener.4. Connect the microphone to the microphone input in the GLM Adapter device.5. Download and install the GLM software at the Genelec web site (). Follow instructions in the software to measure and set up your monitors.6. If you plan not to use a computer for managing monitors, store settings in monitors with GLM software (menu item “Store | Store the Current Group Settings…”).Enable stored settings by turning the DIP switch “Stored” on the monitor to ON after the network has been disconnected.The CONTROL NETWORK RJ-45 connectors are not Ethernet LAN compatible. Do not connect to Ethernet LAN.Stand-alone Mode: Setup Without UsingThe GLMYou can adjust the 8351B without GLM using the controls on the back of the monitor. These stand-alone settings are limited and provide some fundamental compensations for room acoustic effects, input selections and input sensitivity. To use, disconnect the GLM management network and set the DIP switch “Stored” to OFF position.Stand-Alone FunctionalityBass Roll-Off ControlThe Bass Roll-Off setting reduces bass level for spaces with strong low frequency reverberation. It reduces output near the4MonitorMounting Position Treble Tilt Bass Tilt Bass Roll-Off Desktop Flat anechoic response None None None None Free standing in a damped room None -2 dB None None Free standing in a reverberant room None -4 dB None None Near field ona reflective surface None -2 dB None -4 dB In a cornerNone-4 dB-4 dBNoneTable 1.

Attenuation can be selected by combining settings on one or more switches.Desktop reflection compensationThe desktop control reduces frequencies near 160 Hz by 4 dB. This compensates the boost when the monitor is placed on a meter bridge or table.Bass Tilt ControlThe Bass Tilt control offers three attenuation levels for the response below 800 Hz. This control is used when monitors are placed near wall or room corner. Attenuation can be selected by combining settings on one or more switches.Treble Tilt ControlThe Treble Tilt control adjusts the high frequencies above 5 kHz. It corrects bright or dull sound and compensates high frequency loss when a monitor is placed behind a screen.LED DisableThis switch turns off the front panel LED light.ISSThis switch activates and deactivates the ISS power saving function when the 8351B is used in a Stand Alone mode. The default time for going to power save mode is 60 minutes, but this can be adjusted in the GLM software.DigitalThe Digital switch selects the digital audio signals A and B carried in one AES/EBU cable. Turning on both switches reproduces the sum of the signals. When both are selected, a 6 dB attenuation is applied to avoid an overload.LevelThe Level switches reduce the monitor output in 10 dB steps (-10 dB, -20 dB and both switches -30 dB). The switches combine with the rotary level adjustment. The total adjustment range is 42 dB. GLM software enables wider level adjustment.StoredThe Stored switch selects between the controls on the monitor back panel (OFF position) or applying the settings stored in the monitor using the GLM software (ON position). Operating EnvironmentThis product is designed for indoor use only. The permissible ambient temperature is 15-35 degrees Celsius (50-95°F) and relative humidity 20% to 80% (non-condensing). To prevent condensation after the product has been in a cool environment, wait at least one hour before opening the packaging and connecting the mains power.Cooling of the 8351B must be ensured. The minimum clearance behind, above and on both sides of the monitor is 50 mm (2 in). When 8351B is installed in a recess, the recess space must be ventilated sufficiently to remove the heat.Mounting and Placing MonitorsMounting OptionsThe Isolation Positioner/Decoupler™ (Iso-Pod™) stand allows tilting of the monitor and isolates vibrations. As delivered from the factory, the Iso-Pod retainer spring is attached to the bottom of the enclosure for vertical orientation. If you want to use the monitor in horizontal position, remove the retainer spring and reattach it5Table 2.

Never use the iso-Pod without the retainer spring as this may cause the monitor to fall.Aim the acoustic axis of the monitor towards the listening position (see Figure 4). Place monitors symmetrically and at equal distances from the listening position. Preference should be made in placing the listening position on the left-right centerline of the room (see Figure 5). If a monitor is placed far (1.0-2.2 m, 3-7 ft) from the acoustically hard wall behind the monitor, a reflection from the wall may reduce bass output. Avoid these distances.Place monitors away from acoustically reflective surfaces. Reflections from desks, cabinets, computer monitors and such objects can colour audio and blur sound images. Place monitors on stands behind and above a mixing console as this usually improves audio compared to placing monitors on a meter bridge. Ceiling and wall mounts are available through Genelec dealers. Monitor mounts attach to four M6 x 10 mm threaded holes on the enclosure back. Consult the Genelec Accessories Catalogue at or distributor/dealer for information.Front Panel LightThe light on the front panel is normally green. Red and yellow colours indicate special situations. See Table 2.Use with SubwoofersGenelec recommends 7300 series subwoofers and the W371 Adaptive Woofer System for 8351B. Consult the on-line Genelec Product Selection Tool at .MaintenanceDo not open the monitor enclosure. Opening the monitor may lead to loss of the monitor calibration and may damage components. There are no user serviceable parts inside. Maintenance or repair can only be done by Genelec certified service.Safety ConsiderationsThe 8351B follows international safety standards. To ensure safe operation, the following warnings and precautions must be observed:• Servicing and adjustment must only be performed by certified Genelec service personnel. The monitor enclosure must not be opened.• Use the product only with a mains cable having a protective ground terminal and with a mains connection with a protective earth terminal. Failing to do so may lead to personal injury.• To prevent fire and electric shock, do not expose the unit to water or moisture.• Do not place objects filled with liquid, such as vases, on the monitor or near it.• Note that the device is not disconnected from the AC mains service unless the power cable is removed from the monitor or the mains outlet.• Free flow of air behind and around the monitor maintains sufficient cooling. Do not obstruct airflow around the monitor.WARNING!The 8351B is capable of producing sound pressure levels in excess of 85 dB, which may cause hearing damage. Sound exposure level integrated over eight contiguous hours should be limited to Leq=80dB(A) to reduce the risk of permanent hearing damage.

泰克公司WFM8200 8300系列波形监视器使用指南说明书
LQV (Luminance Qualified Vector) Measurements with the WFM8200/8300How-To GuideIntroductionThe patented Luminance Qualified Vector (LQV) Display enhances the current Diamond/Split Diamond, Arrowhead and Vector Displays by allowing the user to view chrominance vectors within specified luminance ranges.Colorists often divide the total tonal range into the High, Mid and Low tonal ranges during the Post Production process. Doing so allows them to make more precise adjustments and enhancements to the scene content. The Vectorscope along with the exclusive Tektronix Diamond and Split-Diamond displays have been extremely valuable tools in terms of detecting and correcting color cast in the overall scene. The addition of LQV enhances these capabilities even more.Figure 1: RGB, LQV High, Vector, LQV LowFigure 1 shows the RGB Waveform in Tile one, LQV (High) in Tile 2, Full Vector in Tile 3 and LQV (Low) in Tile 4.The Luma Qualified Vector (LQV) display adds the capability to see color cast in the High, Mid, and Low tonal ranges. This is a significant enhancement because it allows the user to view color or color cast in specific regions of the picture. For example, when doing rock concerts the bright lighting often causes problems and up to now there has been no real way to easily know if you are balanced in these bright areas. LQV provides the tool needed to make sure balance is right in the Highs & Lows. The user can set upper and lower limits that can define different ranges for variety of applications.While it is possible to show up to four LQV Displays simultaneously depending on the user’s specific application, it is more likely that the focus would be placed on monitoring the Highs and Lows along with the Full Vector as shown in Figure 1.The terms HIGH and LOW as used here are somewhat relative. That is to say, that the range of values considered as being HIGH or LOW may vary according to user preference or the specific content being evaluated. In this case I simply chose approximately the top 20% of luminance levels to represent the HIGHS and the lower 20% of luminance levels to represent the LOWS.The terms HIGH and LOW as used here are somewhat relative. That is to say, that the range of values considered as being HIGH or LOW may vary according to user preference or the specific content being evaluated. In this case I simply chose approximately the top 20% of luminance levels to represent the HIGHS and the lower 20% of luminance levels to represent the LOWS .To Set Up the LQV Display(s):1. First select the tile you want to place the LQV Display (Tile 2 in Figure 2):2. Next depress the Vector Button below the display screen to place the vector display in that tile as shownin Figure 2:Figure 2. WFM8300 Front Panel3. Next Depress and Hold the Vector Button to display the Menu as shown in Figure 3 and use the up/downselection keys to select the Luma Qualified Vector and then use the Right Arrow Key to set this to the ON position.4. Now use the up/down selection keys to select the Luma High and Luma Low settings using the GeneralKnob (upper right hand corner) to set the luma limits you want to establish.5. Press the Vector button to clear the menu.6. Repeat this process for any addition LQV Displays you wish to set up with different ranges.See if you can duplicate the display in Figure 1.Figure 3. LQV Range MenuOnce you have these set-up the way you like it you can save the setting as a Preset for fast and easy recall. In fact you’ll probably want to save several variations of this based on specific applications.

银河插卡数字机的几个实用功能
银河插卡数字机的几个实用功能作者：从容来源：《卫星电视与宽带多媒体》2011年第11期香港天浪直播系统，可以说是第一个真正的直播到户的中文节目卫星直播系统，因其采用DBS转发器，圆极化大功率直播，所以用很小的天线就可以满意接收。
天浪启播于2005年1月7日，止播于2009年6月30日，仅存在了四年半的时间，也可能是存在时间最短的卫星直播系统。
天浪直播采用爱迪德（IRDETO）加密系统传送，理论上只要是能解此加密系统的接收机都可以使用，或用爱迪德模块配以解码智能卡使用均可。
天浪官方推荐使用的是一款同洲的机器，当然是一款家用机型，但因其购买非常费劲，而且价格高昂，实际市场上并没有多少此型号机器在使用。
尽管最常见的XSAT410系列机器都可以刷成IRDETO系统，但后来天浪反制均出现黑屏而无法正常使用。
真正大量使用的机器实际上是银河的几款IRDETO正版系统的插卡机。
因为是正规大厂的机器，尽管也定位于家用机型，但仍被许多商家用于系统前端作工程传送使用，可见此机品质非同一般。
本人接触了许多这类银河机器，从2005年至2007年三年间，这类机器也经历了多种版本的变化，在硬件上也有些许不同，但其性能一如既往的稳定，在众多商家中有较好的口碑。
大家所说的银河机，在机器及其包装上其实从没有出现“银河”二字，真正的品牌是Supernet，型号有两个，一个是2580I，另一个是488，两个型号主要的区别就是是否有色差输出，当然在主芯片上也有所不同，前者用富士通的MB86H25A，后者用的是MB86H20B，具体差异见附表。
当然它们还有一个共同的特点，就是都是出口机型，虽然有包括英语在内的多种语言的菜单，但唯独没有中文操作菜单。
我们先来看一下几种机器外观上的差别。
图1是后面板输出端口的差异，很明显，最上面的一台是有色差输出的机器，另有一组AV输出，一个RS-232串口（公头），一入一出式的卫星一体化调谐器，一入一出式的调变频调制器，右侧条码标签上的生产日期是2007年。

系统建设的历史问题造成视频监控、一卡通、入侵防盗、安全生产管理等业务需要支出较大的人力、物力，耗费了很大的资源，且无法做到中心统一管理，延迟了紧急事件的响应时间，无法起到事故防范的作用。
因此，行业迫切需要实现对整个生产园区日常生活管理、生产作业、运输等各个环节的统一监管。
视频监控系统与其他管理系统集成，构建整个生产园区的可视化管控平台是重要的科技手段之一，统一管理成了必行之势。
