Both Dahua and Hikvision are highly reputable manufacturers in the industry. We’ve mentioned them both on a number of other occasions because they’re worth talking about. In this case, they directly relate to HDCVI and HDTVI more than just selling it.
Dahua is both the developer/creator of HDCVI and the sole manufacturer of HDCVI Digital Signal Processors (DSP) and HDCVI Digital Video Recorder (DVR) boards. In the case of HDCVI, the DSP is responsible from compressing the data from the camera and sending it through the attached cabling. Without an HDCVI specific DSP, you don’t have an HDCVI camera. The HDCVI DVR boards are a little easier to understand. To make a long story short, if you want an HDCVI DVR, the board is going to be made by Dahua.
Hikvision partnered with Techpoint to come up with HDTVI. We saw a lot of delays with the release with HDTVI. Some people credit this to the two companies struggling to perfect the technology while the majority seems to lean more towards them not wanting to release the new line so close to Dahua releasing HDCVI. Due to the fact that HDTVI was second on the market, HDCVI is little more popular right now just by word of mouth. Unlike Dahua, Hikvision has opted for a more “open source” approach. Instead of taking the sole manufacturer route of specific components, they have opted to release the information necessary for other manufacturers to produce their own variations (presumably for a price).
There has been a lot of debate regarding the way in which Dahua and Hikvision have released HDCVI and HDTVI. A lot of people are on Hikvision’s side here, but we’re not entirely sure why and we’re not alone. Open source seems to make them the good guys in this scenario but the side effects of it in this industry have been detrimental; so much so that people have been second guessing HDTVI altogether lately. The fact is no one is producing better HDTVI products than Hikvision, and if they do, we haven’t seen them yet. All this means is that they’ve opened the doors and unleashed a flood of faulty and cheap variations on the market. Your average consumer doesn’t have a lot of knowledge on the subject as it is, so to clutter the market with substandard products such as these makes things even more difficult. In addition to this, these other manufacturers have been spewing all kinds of nonsense regarding the capabilities of HDTVI. We’re not going to come right out and say that they’re lying, but no one honestly knows. Each manufacturer could have a slightly different set of capabilities based on their own design, but it’s much more likely that the information they’re putting out to the general public is just incorrect. This industry loves to lie, so take everything with a grain of salt.
