The definition of a home HD DVR is a DVR that is suitable for general home use and has a physical input interface such as HDMI, AV, component, VGA, SDI, and HD-AHD (BNC) to support 1080P high-resolution parameters. Such as home HD video surveillance, recording digital TV set-top boxes, recording network players, recording Blu-ray high-definition player, recording home DV machines, ripping old tape recorders and home recording desktop computer laptops and other occasions used hard disk recorders. At present, there are many types of home-use hard disk video recorders on the market. There are many brands and models, but there are not many models capable of achieving high-definition video recording. Most of them are analog HD video recorders in the surveillance field. To make it easier for families to choose the model that is suitable for their own use, this article is briefly described as follows.
First, select the basic elements of home HD video recorder 1, video recorder input and output interfaces with the family needs to record the output interface of each section of the playback device.
The input interface of the video recorder: The TV set-top box for general home use basically has an AV (CVBS) output interface. The new digital TV set-top box has an HDMI output interface. Old-fashioned video tape recorders are basically AV output interfaces. The newly-listed DVs basically have HDMI output interfaces. Blu-ray players not only have HDMI output, but also have AV output. Home desktop computers are basically VGA output interfaces, while notebook computers have VGA and HDMI output interfaces. Therefore, to ideally record the playback devices that the home has already purchased, selecting the video recorders that both the HDMI and the AV input interfaces have is a prime choice. In order to take care of the recording of the computer, you must select a recorder model that not only has HDMI, AV input, but also VGA input. There are few home-playing devices with a color-difference output interface unless it is an "antique" home player. Surveillance video has been in the home for a long time. Before the home surveillance video recorders were basically analog AV recorders with AV input, the recording effect was normal. To achieve home HD monitoring, at least select HD-AHD or SDI input interface models.
The output interface of the video recorder: The television is already the necessary audio and video display device for the majority of families. TVs purchased in recent years are basically high-definition LCD TVs with HDMI and AV input interfaces, while older desktop analog TVs have only AV input interfaces. Currently, there are HDMI output interfaces for home HD video recorders that are listed on the market. However, if you want to use TVs with only AV inputs in your home, you must select a hard disk recorder model with AV output.
2. According to the resolution parameter output by the home playback device, the corresponding HD video recorder can be selected.
The HDMI output resolution parameter of the general digital television set-top box is 1080I60hz downward and 720P60 is optional, and can be compatible with general home HD video recorders. Blu-ray player output is relatively rich in resolution, down from 1080P60hz optional. In terms of general visual clarity, there is a slight difference between 1080P60hz and 1080P24hz, but the gap is not significant. The 1080P24hz and 1080I60, 50 are basically no big gap, it is difficult to see the difference. 720P60hz on the color and 1080I60 not much difference, but a slight gap in the degree of sophistication. Most of the HDTV recorders on the market such as the HDT series that support the highest input resolution are 1080P24hz, which exceeds the output parameters of the general digital TV set-top box. To record a Blu-ray player, the Blu-ray player's HDMI output resolution must be set. The parameters can be adjusted to 1080P24hz or below. If the playback parameters of the playback device of the guest exceed 1080P24hz and cannot be adjusted and lowered, the HDT-5 or WHD-01S models in the high-end HD recorders such as the HDT series should be selected.
3. Select compatible HDCP protocol, support for recording all types of encrypted video models With the improvement of copyright policy, whether it is a digital TV set-top box or all types of Blu-ray high-definition players, have joined the copyright protection of the HDCP protocol, if the video recorder input No HDCP protocol is compatible with recording. Although there are cracked devices sold on the Internet, the resolution of the output after the cracking is reduced to analog signals, and the resolution is poor.
4, choose the cost-effective products, in line with their families' financial expenditure conditions.
Popular home appliances, the price should not be high, has been listed on the HDT series of home video recorders for nearly eight years, the basic price of not more than 3,000 yuan, mostly between 1000-2000 yuan, more welcomed by customers.

Although there are only domestic HDT series home HD recorders on the market in the past seven or eight years, similar products have been listed in Europe, America, Taiwan, and other regions in the near future. However, such extra-territorial products are based on operating habits set by overseas users and used by domestic users. Different habits, and domestic HDT series models are based on the operating habits set by the country's operating interface, practical and more convenient, so the purchase of domestic machines is better.
6, choose to consult and guide easy maintenance, after-sale more secure brand products As mentioned above, there are domestic machines in the market also have imported machines, but because the domestic HD DVR itself originated in the domestic R & D launched, domestic models after nearly a decade R&D upgrades, especially the well-known domestic brands HDT series products, have been very mature and stable.
