1.3DDNR: 3-D Digital noise reduction. For processing thevideo so there is less noise (noise are something like those colorful static, snowy things on the video, can be from any electrical interference.
2. Auto Iris: The Auto Iris Lensis a type of lens that can be electronically controlled. This type of lens allows maintaining the lighting level. It is applicable where the light condition varies continuously. Auto iris lens allows the camera to adjust to get the best picture in the given lighting conditions. There are two types of Auto iris lenses, Fixed Auto Iris lenses and Varifocal Auto Iris lens. Auto iris lenses are best lens to use in any application as they are flexible and can adjust to changing light levels. Auto iris lenses are used to produce consistent video signals from cameras that view scenes in any varying light levels. Auto iris lenses combines an electronically controlled iris, which allows the lens to maintain one light level making them ideal for outdoor users any other applications.
3. Baud Rate: The baud rate is associated with many mathematical formulas. Its units are either symbols per second or pulses per second. Baud can be determined by using the following formula: Baud =(Gross Bit Rate /Number of Bits per Symbol). This can be used to translate baud into a bit rate using the following formula: Bit Rate =(Bits per Symbol * Symbol Rate). Baud can be abbreviated using the short eneddform “Bd” when being used for technical purposes. Setting for PTZ, Baud rate/Camera address/Protocol on camera must be the same as on the DVR in order to make the PTZ from the DVR.
4.Cables VGA: Video Graphics Array (VGA) refers specifically to the display hardware first introduced with the IBM PS/2 line of computers in 1987. BNC: The BNC connector (Bayonet Neill–Concelman) is miniatures quick connect or disconnect RF connector used for coaxial cable. It features two bayonet lugs on the female connector; mating is
achieved with only a quarter turn of the coupling nut. BNC are ideally suited for cable termination for miniature-to-subminiature coaxial cable. HDMI: High-Definition Multimedia Interface is a compact audio/video interface for transferring uncompressed digital video data and compressed/uncompressed digital audio data from an HDMI-compliant device (“the source device”) to a compatible digital audio device, computer monitor, video projector, or digital television. HDMI is a digital replacement for existing analog video standards. HDMI support 1080P.
5. CCD: Charger-coupled-device also refers to the camera’s image sensor.
6. CMS: Central Management system, the software on the CD that ships with our DVR is this program, allowing multiple DVR and up to 1000 cameras to be view at the same time.
7. CMOS: Complementary metal-Oxide-semiconductor refers to the camera’s image sensor technology. (cheaper to manufacture, also smaller, uses less power and a
newer technology)
8. CS Mount( Sea wolf box camera): refers to the mounting style of the lens, the way the lens screw into the box camera.
9.DVR: A digital video recorder (DVR), sometimes referred to by the merchandising term personal video recorder (PVR), is a consumer electronics device or application software that records video in a digital format to a disk drive, USB flash drive, SD memory card or other local or networked mass storage device. The term includes set-top boxes (STB)with direct to disk recording
facility, portable media players (PMP) with recording, recorders (PMR) as camcorders that record onto Secure Digital memory cards and software for personal computers which enables video capture and playback to and from a hard disk drive. A television set with built-in digital video-recording facilities was introduced by LG in 2007, followed by other manufacturers.
10. Dual stream: Master stream and Sub stream. Master stream: same FPS and resolution at live view and DVR (ex: D1 at 30 fps), required more bandwidth. Sub stream: lower the FPS and resolution of the live video (ex: D1 at 30 fps at the DVR will become CIF at 7fps in internet explorer, can be change inside setting, and required more bandwidth). Sub stream is good for networks with slow upload speeds, all the cameras are on sun stream by default when you access it remotely.
11.Digital Zoom: Digital zoom on the other hand is not a true form of a zoom function. The image itself doesn’t actually come any closer as the optics in the camera stays the same.
The way the digital zoom works is much the same way as it does on your PC at home. The idea behind digital zoom is that it takes a portion of the image and expands that image to the full size of the picture. What happens here isthat the section of image that you are looking at becomes bigger, not closer. The image does look closer because it has been expanded however all that has
happened is that the image quality has been reduced because it has been expanded with no new data for the image. There is nothing digital zoom can do that you can’t do on any standard art package at home. You may as well take the picture like you would a normal camera and then alter the zoom to exactly the way you want it at home. It will be no better or worse doing it this way
that it would using a digital zoom function.
12. Dual core:refers to the processor in the motherboard of the DVR, will be able to format hard drive faster, and boot up faster, same as old DVR, but faster.
13. DVD RW: DVD burner for the DVR.
14.E-Map: One of the function of CMS, able to take a picture (ex: a floor plan)click and drag connected cameras to specific spots on the picture (ex: Drag the front door camera to the front door spot on the floor plan) and double clicking the camera icon will pop up a live view of the camera.
15.FPS: Frame rate (also known as frame frequency) is the frequency (rate) at which an imaging device produces unique consecutiveimages called frames. The term applies equally well to film and videocameras, computer graphics, and motion capture systems. Frame rate is mostoften expressed in frames per second (FPS) and is also expressed in progressive scan monitors as hertz (Hz). 30 FPS is real time.
16. Fisheye camera: A fisheyelens is an ultra-wide-angle lens that produces strong visual distortionintended to create a wide panoramic or hemispherical image.[1][2] Fisheye
lenses achieve extremely wide angles of view by forgoing producing imageswith straight lines of perspective (rectilinear images), opting instead for aspecial mapping (for example: equisolid angle), which gives images acharacteristic convex non-rectilinear appearance. In simple, fisheye cameracan have a really wide angle view.
17.GB/TB: refer to the harddrive size. Gigabyte/ Terabyte, 1000GB=1TB.
18. HD: High Definition 720 P (1.3Megapixel, 1280×1024) Full HD: Full High Definition 1080 P (2.1 Megapixel, 1920×1080)
19.DSP: Digital Signal Processing, a technique by which video quality can be improved by adjusting parameters of the video signal.
20. HD-SDI: Serial digitalinterface (SDI) is a family of video interfaces standardized by SMPTE (TheSociety of Motion Picture and Television Engineers). For example, ITU-RBT.656 and SMPTE 259M define digital video interfaces used forbroadcast-grade video.A related standard, known as high-definition serialdigital interface (HD-SDI), is standardized in SMPTE 292M; this provides a nominal data rate of 1.485 Gbit/s.
22.IP camera: An Internet protocol camera, or IP camera, is a type of digital video camera commonlyemployed for surveillance, and which unlike analog closed circuit television
(CCTV) cameras can send and receive data via a computer network and the Internet. Although most cameras that do this are webcams,the term “IPcamera” or “netcam” is usually applied only to those used for surveillance. can be hooked into a router with a PoE witch, can be uses with a NVR or just by itself (access the IP camera with its IP address or theprogram that comes with it called PSS (Pro Surveillance System), can also be accessed with smart phone app iDMSS after ports are opened on the router forthe IP camera.
23.IR cutter : Infrared cut-off filters, sometimes calledIR filters or heat-absorbing filters, are designed to reflect or blockmid-infrared wavelengths while passing visible light. They are often used indevices with bright incandescent lightbulbs (such as slide and overheadprojectors) to prevent unwanted heating. There are also filters which are
used in solid state (CCD or CMOS)video cameras to block IR due to the highsensitivity of many camera sensors to near-infrared light. These filterstypically have a blue hue to them as they also sometimes block some of thelight from the longer red wavelengths. In simple, an IR cut filter is anextra filter inside the camera that moves behind the camera lens when it havelow light source. A camera with an IR cut filter will produce very highquality images in low light condition.
24. Lux Rating: A LUX,abbreviated lx, is the International System of Units (SI) measure of theintensity of light. It can be thought of as the strength of light asdetermined by the human eye. A LUX is based on another unit of lightmeasurement called a lumen, which is based on yet another unit called acandela. In the United States, the non-SI unit to measure light intensity is
the footcandle. One foot candle is approximately equal to 10.8LUX. In orderto put things in perspective, here some are some setting examples with theirequivalent LUX rating:• A quarter moon-lit night produces about .01 LUX• Afull moon on a clear night produces about 0.27 LUX• A full moon on a clearnight near the equator produces about 1 LUX• An average family room produces about 50 LUX• An overcast, dark day produces about 100 LUX• Typical officelighting ranges from about 300 to 500 LUX• Direct sunlight can range fromabout 30,000 to 130,000 LUXThe LUX rating of a security camera is based onseveral factors, three of which are the lens,sensor chip, and “F stop.” Thelower the LUX rating of a security camera the less light is needed for the camera to produce a usable picture (video).
25. Manual Iris: The Manual Iris lens is the simplest type of iris control lens with manual adjustment toset the iris opening in a fixed position. These are generally used for fixed
lighting applications or where the camera to be used is readily accessible.The lens is outfitted with a ring on the body that can be turned to alter theaperture directly. There are two types of Manual iris lenses, Fixed ManualIris lensesand Varifocal Manual Iris lens.The Manual Iris lens is convenientto use where it is not necessary to adjust the lens continuously for correctpicture brightness. These types of lens are used with constant light. It is applicablein shopping centers, schools,libraries, and offices. The lens can be turnedto alter the aperture directly with the help of a ring which is present onthe body.
26. NVR: network Video Recorder
27.Night wolf: Marketing termof image sensor by Pixim for their IR at night or lowlight area. 28.OpticalZoom: Optical zoom is what I like to call true zoom. This function of acamera uses the lens within the camera to draw the image closer. Using theoptics of the camera the image is bought forward much the same way as
binoculars and other such instruments. When using optical zoom qualityremains the same and the full resolution of the camera can be used on thezoomed image.Different levels of optical zoom can be achieved by changing thedistances between the lenses. The motion of the front lens moving outwards ona camera is the lens achieving a greater level of zoom. The rating of opticalzoom on a camera is measured like 2x 4x 8x etc. bringing the image 2x 4x and8x closer respectively. The best cameras have a high level of optical
zoom.
29.OSD: On screen menu.
30. PoE : Power over Ethernet
31. PTZ: Pan,Tilt, Zoom, you can move the camera left and
right, up and down and zoom in and zoom out.
32.Pixelplus: marketing term for CMOS sensors by Pixelplus company
34. RS485: EIA-485, also knownas TIA/EIA-485 or RS-485,is a standard defining the electricalcharacteristics of drivers and receivers for use in balanced digital
multipoint systems. The standard is published by theTelecommunications/Electronic Industries Alliance (TIA/EIA). Digital communicationsnetworks implementing the EIA-485 standard can be used effectively over longdistances and in electrically noisy environments. Multiple receivers may beconnected to such a network in a linear, multi-drop configuration. Thesecharacteristics make such networks useful in industrial environments andsimilar applications. Communication between DVR and PTZ/zoom cameras, A/B=positive/ negative. Y/Z=positive/negative. Positive wires of camera connectsto positive port of DVR, negative wires of camera connects to negative portof DVR. RS stands for “Recommended Standard”
35.Sens-up: Sens-up in theory
make a camera more sensitive to light so it can produce images even in low
lux (low light) conditions. Sens-up tries to eliminate the need for IR
cameras which uses IR LED’s or invisible light to providing images in low lux
or in the pitch dark.36.Smart IR: Automatically adjust the infrared light
required in a scene as the subject moves closer or further from the camera,
resulting in a clear image that is not washed out or too dark. Farther away=
more IR light. Closer= less IR light.
37. SATA HDD:SATA refers to the
connection between the motherboard and the hard drive. HDD refers to hard
drive that installed on the DVR.
38. Spot out:Port forconnecting the DVR to a regular TV, will then feed a video which will rotateto the next channel after a time. Useful for making sure customers know thatthey are being watched.
39.Seawolf: Marketing tern of image sensor by Pixim,mostly about the WDR.
40.Sony Effio-P: Sony’s brand of image processor and WDR.
41.Starlight: technology that is much more sensitive and better in low-light setting than traditional IR.
42. TVL:Television lines (TVL)is a specification of an analog camera’s or monitors’ horizontal resolutionpower.It is alternatively known as Lines of Horizontal Resolution (LoHR), akalinesof resolution . The TVL is one of the most important resolution measuresin a video system. The TVL can be measured with the standard EIA-1956resolution chart.
