In the most basic terms, HD Ready TVs (and set-top boxes) are capable of displaying 720p video, which is 1280x720 pixels. Full HD TVs and boxes can show 1080p video, which is 1920x1080 pixels. The HD Ready standard came about in Europe around 2005, so that people could be sure they were buying TVs that actually supported HD.
In the US, HD Ready for a TV means that the display can output 720p images. In most cases, this also indicates that the TV has a built-in digital tuner, which is necessary to accept digital TV broadcasts (which have largely replaced analog signals). This same HD Ready logo is also printed on several projectors, computer monitors, and other devices, which don't have a tuner.
TVs show video as a series of lines; resolution is simply the amount of pixels that make up a display, both horizontally and vertically. The shorthand numbers used for resolution (720p and 1080p) represent how many vertical lines can your TV display at one time.
1920x1080 resolution (1080p) means that there are 1920 pixels horizontally and 1080 pixels vertically. 720p resolution is 1280x720 pixels. Having a higher resolution results in a sharper image, because there's more information on the screen at once.
Interlaced video conserves bandwidth, and was thus used in older analog TV broadcasting. While efficient, it's also more susceptible to distortion, especially for fast-moving video. In the US, most TV broadcasts today are either 1080i or 720p, with the latter preferred for sports since they move quickly.
Remember that video will play at the lowest resolution supported by any device in the chain. For example, if your TV is Full HD (1080p), but your set-top box is only HD Ready (720p), your TV will show 720p video. A PlayStation 4 capable of outputting in 1080p won't be able to show that 1080p video on a 720p TV.
720p resolution has become the default minimum for nearly every display device. If you're buying a TV, monitor, projector, or anything like that, it will almost certainly support 720p video at least. Unless it's extremely cheap, chances are that it supports 1080p as well; the Full HD tag lets you know for sure.
But when considering a purchase, you should go beyond these stickers and check the actual product details of a display before you buy it. Online, look in the specifications for a field titled Resolution or similar, which should have a value like 720p or 1920x1080. When in a store, look at the device's box or ask an employee for more details.
In general, unless you're looking to spend as little money as possible, we don't recommend buying any display that's under 1080p. While 720p is still referred to as "HD," 1080p is the HD standard in most people's minds. It's used for Netflix streaming, Blu-ray discs, game consoles, and similar.

Our IP camera can connect directly to your network or computer, and there are three ways to do so. The three ways listed below do not require a NVR. A NVR, or Network Video Recorder, is the device that IP cameras connect to. The NVR records video provided by the IP cameras to a hard drive, either in HD (720p, 1080p), 2K HD, or Ultra HD (4K) depending on the type of NVR and type of camera that's being used with it.
NVR products are standalone devices using a Linux operating system which is known to be rock-solid and crash free, and designed to be operate 24/7 and maintain system security with user account access permissions. For a complete security camera system, you will want to use a NVR along with cameras. SmartPSS software can be used as a client software to connect from a computer to a NVR to watch cameras connected to the NVR and to playback/download recorded security footage.
Format identifiers like 576i50 and 720p50 specify the frame rate for progressive scan formats, but for interlaced formats they typically specify the field rate (which is twice the frame rate). This can lead to confusion, because industry-standard SMPTE timecode formats always deal with frame rate, not field rate. To avoid confusion, SMPTE and EBU always use frame rate to specify interlaced formats, e.g., 480i60 is 480i/30, 576i50 is 576i/25, and 1080i50 is 1080i/25. This convention assumes that one complete frame in an interlaced signal consists of two fields in sequence.
Given a fixed bandwidth and high refresh rate, interlaced video can also provide a higher spatial resolution than progressive scan. For instance, 19201080 pixel resolution interlaced HDTV with a 60 Hz field rate (known as 1080i60 or 1080i/30) has a similar bandwidth to 1280720 pixel progressive scan HDTV with a 60 Hz frame rate (720p60 or 720p/60), but achieves approximately twice the spatial resolution for low-motion scenes.
Interlacing was ubiquitous in displays until the 1970s, when the needs of computer monitors resulted in the reintroduction of progressive scan, including on regular TVs or simple monitors based on the same circuitry; most CRT based displays are entirely capable of displaying both progressive and interlace regardless of their original intended use, so long as the horizontal and vertical frequencies match, as the technical difference is simply that of either starting/ending the vertical sync cycle halfway along a scanline every other frame (interlace), or always synchronising right at the start/end of a line (progressive). Interlace is still used for most standard definition TVs, and the 1080i HDTV broadcast standard, but not for LCD, micromirror (DLP), or most plasma displays; these displays do not use a raster scan to create an image (their panels may still be updated in a left-to-right, top-to-bottom scanning fashion, but always in a progressive fashion, and not necessarily at the same rate as the input signal), and so cannot benefit from interlacing (where older LCDs use a "dual scan" system to provide higher resolution with slower-updating technology, the panel is instead divided into two adjacent halves that are updated simultaneously): in practice, they have to be driven with a progressive scan signal. The deinterlacing circuitry to get progressive scan from a normal interlaced broadcast television signal can add to the cost of a television set using such displays. Currently, progressive displays dominate the HDTV market.
In the late 1980s and early 1990s, monitor and graphics card manufacturers introduced newer high resolution standards that once again included interlace. These monitors ran at higher scanning frequencies, typically allowing a 75 to 90 Hz field rate (i.e. 37.5 to 45 Hz frame rate), and tended to use longer-persistence phosphors in their CRTs, all of which was intended to alleviate flicker and shimmer problems. Such monitors proved generally unpopular, outside of specialist ultra-high-resolution applications such as CAD and DTP which demanded as many pixels as possible, with interlace being a necessary evil and better than trying to use the progressive-scan equivalents. Whilst flicker was often not immediately obvious on these displays, eyestrain and lack of focus nevertheless became a serious problem, and the trade-off for a longer afterglow was reduced brightness and poor response to moving images, leaving visible and often off-colored trails behind. These colored trails were a minor annoyance for monochrome displays, and the generally slower-updating screens used for design or database-query purposes, but much more troublesome for color displays and the faster motions inherent in the increasingly popular window-based operating systems, as well as the full-screen scrolling in WYSIWYG word-processors, spreadsheets, and of course for high-action games. Additionally, the regular, thin horizontal lines common to early GUIs, combined with low color depth that meant window elements were generally high-contrast (indeed, frequently stark black-and-white), made shimmer even more obvious than with otherwise lower fieldrate video applications. As rapid technological advancement made it practical and affordable, barely a decade after the first ultra-high-resolution interlaced upgrades appeared for the IBM PC, to provide sufficiently high pixel clocks and horizontal scan rates for hi-rez progressive-scan modes in first professional and then consumer-grade displays, the practice was soon abandoned. For the rest of the 1990s, monitors and graphics cards instead made great play of their highest stated resolutions being "non-interlaced", even where the overall framerate was barely any higher than what it had been for the interlaced modes (e.g. SVGA at 56p versus 43i to 47i), and usually including a top mode technically exceeding the CRT's actual resolution (number of color-phosphor triads) which meant there was no additional image clarity to be gained through interlacing and/or increasing the signal bandwidth still further. This experience is why the PC industry today remains against interlace in HDTV, and lobbied for the 720p standard, and continues to push for the adoption of 1080p (at 60 Hz for NTSC legacy countries, and 50 Hz for PAL); however, 1080i remains the most common HD broadcast resolution, if only for reasons of backward compatibility with older HDTV hardware that cannot support 1080p - and sometimes not even 720p - without the addition of an external scaler, similar to how and why most SD-focussed digital broadcasting still relies on the otherwise obsolete MPEG2 standard embedded into e.g. DVB-T.
We recommend a minimum network bandwidth of at least 15 Mbps for 720p 60Hz streaming, 30 Mbps for 1080p 60 FPS, 35 Mbps for up to 1600p. Note: An ethernet connection is required for best results streaming at 1600p at 120fps. 2ff7e9595c
