Entering the security or computer city, all kinds of DVRs are dazzled, which makes many engineering companies, especially those who are new to it, unable to start. Below we will introduce the key points of purchasing DVR cards one by one. Remote monitoring Frame rate stability service price
Stainless Steel (Stainless Steel) is referred to as acid-resistant stainless steel, resistance of air, steam, water and other weak corrosive medium or stainless steel having resistance as stainless steel; and the resistance to chemical corrosion medium (acid, alkali, salt and other chemical leaching pitting) corrosion of steel known as acid-resistant steel. As the two differences in the chemical composition of leaving their corrosion resistance is different from ordinary stainless steel general impatience chemical corrosion, and acid-resistant steel are generally of a stainless steel.
So now Stainless Steel Padlock with his unique quality, it won a lot of the market, particularly in Europe, is located in the cold zone countries.

Remote monitoring is an indispensable function of DVR monitoring, but there are still many engineering companies lacking full confidence and confidence in the realization of remote monitoring. Remote monitoring function includes dynamic domain name application download and installation settings, router port forwarding, IE remote monitoring also needs to enable unsigned ActiveX controls, remote playback, remote recording, remote backup, remote PTZ control, etc., and remote monitoring under the same public IP , Multiple DVRs with different private IPs, centralized monitoring technology, etc., the engineering company should test all the above functions, and observe the remote picture quality, rather than just looking at the smoothness.
DVR is divided into real-time and non-real-time DVR. Real-time DVR is divided into preview real-time playback and real-time video preview non-real-time. Most DVR frame rates can be adjusted. Select or set the corresponding frame rate according to engineering requirements.
Stability may not necessarily be found during the product testing process. Sometimes it takes time and a variety of different environments to check the stability. In addition to repeated testing by yourself, you should also examine the length of time and sales volume of the DVR card in the market. Size comes to the side.
Services include service attitudes and service capabilities. Service attitudes are constantly changing. It will change with the mood, busyness of the suppliers, and the value of customers in the suppliers. Service capability is a reflection of the supplier's security knowledge level and experience. Many engineering companies buy DVR too often and look at the price too much, and ignore the service afterwards. Many engineering companies are unable to receive timely service due to engineering technical difficulties or product damage, and the projects do not meet the standards, resulting in their goodwill in the local area. Or the interests are affected, and even the advances cannot be received. Therefore, the engineering company must improve the security knowledge, through the technical exchange with the supplier, to perceive whether the other party has service capabilities. In China, although there are no fewer than a hundred DVR card manufacturers claiming to be themselves, there are currently less than 10 R & D manufacturers of soft and hard compression DVR cards, a large part of which are pirated and OEM, and some are "jianghu programmers." The DVR works at home are resold to some DVR companies. Such products not only have not passed the stability test, but also difficult to obtain the corresponding technical services, so that the engineering and equipment manufacturers who choose them will be sweet and bitter.
Prices often vary depending on production costs, brands, services, product quality, and marketing strategies. Equipment vendors often choose DVR cards of different price points due to their financial capabilities, product profitability, and market demand. There are many misbranded, inferior, or pirated DVRs in the market. Often grab the market at a low price, many engineering companies are often fooled by the appearance that the low price is actually a high price, for example: an engineering company has used a total of 100 mixed-brand 4-way DVR cards, the retail price is 180, the damage rate after one year 20%. After one year, the supplier will go bankrupt, lose money, or switch careers. Because they are miscellaneous brands, they do not need to consider their brand reputation. The immediate benefit is the first. Then the damaged products cannot be serviced and guaranteed, resulting in an increase in actual prices. The price becomes 225 yuan. The price of some big brands of soft compressed DVR is 220, at least 1 year warranty, the actual price is still 220, but the price is low, if you consider the quality of the brand and miscellaneous products themselves, the difficulty and efficiency of use, and the miscellaneous DVR two or three After more years of damage, the real price is much higher than that of high-quality brand DVR. It is more and more people realize this. The largest domestic sales of hard-compressed DVR are the most expensive Haikangka, the domestic The largest sales volume of soft-compressed DVRs are wave particle cards with the most expensive surface prices. They are only the most expensive on the surface, the most competitive in real prices, and even cheapest. This also shows that vicious price wars are not possible in the DVR industry. Fetched.
