Copy & Paste of some(!) of the text from the link of the 4 highlights (in my view):

Alpha Imaging
Alpha Imaging Technology Corp. - a growing Taiwanese manufacturer, since 2002 has been producing chipsets for phones, video recorders, action cameras, ip-cameras and videoniyan.K popular products of this brand include:

  • AIT8427 (500MHz, FullHD 30 frames per second, Wide Dynamic Range). On this productive and reliable chip are made Neoline Wide S35 , Trendvision TDR-200 , as well as the popular hybrid Karkam Kombo 2 .
  • AIT8428 (dual-core 600MHz, 1920x1080 @ 60fps or 2704x1524 @ 30fps, HDR / WDR, recording from two channels, WiFi). Powerful and expensive, it is more relevant for action cameras.
  • AIT8328 (600MHz, FullHD, Wide Dynamic Range, recording from two channels).
  • AIT8437 (500MHz, 1920x1080 30fps or 1280x720 60fps, WDR)
Allwinner
Allwinner Technology is a Chinese company that manufactures chipsets for smartphones and video cameras. Founded in 2007 in Zhuhai City, Guangdong Province. Among the System on Chip of this brand are the most popular:

  • Allwinner A10 - based on the core Cortex A8 with a frequency of 600 hertz. An example of use is two-channel Neoline Wide S47 Dual and Parkcity DVR HD 460.
  • Allwinner A13 - based on the Cortex A8 core with a frequency of 600 hertz.
  • Allwinner A20 - based on the dual-core Cortex A7. This chip produced a two-chamber Neoline G-TECH X23.
  • Allwinner A23 - based on dual-core Cortex A7 with a frequency of up to 1.5 GHz.
  • Allwinner F20 - can To record from two channels with a resolution of 1280x720 30 frames per second.
  • Allwinner V3 . - Based on dual-core Cortex A7 with a frequency of 1.2 GHz, allows you to record 1920x1080 @ 60fps or dual-channel 1920x1080 @ 30fps.
NOVATEK
Novatek is one of the most popular manufacturers on the market today "system on chip" for DVRs and action cameras. Founded in 1997 in Taiwan, today has representative offices in China and Japan. Many devices on the market are made on the basis of chipsets of this brand:

  • Novatek NT96220 - entry level, able to shoot with a resolution of 30 frames HD or interpolation Full HD 25 frames per second, while using the outdated MJPEG codec, that is, the files take up 2 times more space on the memory card. NTK96220 is used in inexpensive Neoline Wide S25 .
  • Novatek NT96226 and NT96632 are also entry-level. Their difference from NTK96220 is that they compress video files better thanks to H.264 codec support.
  • Novatek NT96550 - can shoot full-fledged FullHD 30 frames, and also integrates with GPS and WiFi-modules.
  • Novatek NT96650 is one of the best processors for mid-range auto-registrars. It perfectly handles FullHD video stream, integrates with GPS and WiFi modules, and also supports WDR and HDR algorithms, improving the quality of shooting in difficult conditions. This chipset produced the popular Street Storm CVR-N9310, CVR-N9710 Light, CVR-N9510 Pro, Neoline Wide S30, Neoline G-Tech X13, as well as in the fashionable SJCam SJ4000 and SJCam SJ5000 action cameras.
  • Novatek NT96655 - supports recording from two channels with FullHD resolution. Used in the new two-chamber Street Storm CVR-N9220 G.
  • Novatek NT96660 is a top-end chipset, it makes it possible to shoot videos with a resolution of 4K (3840x2160 @ 24fps), 2K (2560x1440 @ 30fps), 1920x1080 @ 60fps and 1280x720 @ 120fps. In demand in the registers and action cameras of premium class: CARCAM 4K, SJCAM M10 +, SJCAM SJ4000 + WiFi, SJCAM SJ5000X.
AMBARELLA
Ambarella is an American concern that produces the most popular chipsets for recorders, video and cameras. Established in 2004, Ambarella constantly worked on improving the products, which allowed it to take the leading place in its field and release several generations of chips:

  • Ambarella A2 . Single-core entry-level models on ARM9 core with a frequency of 150-200 hertz. IncludesA2S30 (1280x720 30 frames per second), A2S60 (can shoot full-fledged 1920x1080 @ 30fps H.264, but the viewing angle is 20-30 percent smaller than with HD shooting), A2S70 (video only at 1280x720 resolution With a frequency of 60fps).
  • Ambarella A5 / A5S - on the ARM11 core with a frequency of 533 hertz. They are very popular with manufacturers, since they are better removed in the dark than A2. The line includes A5S25 and A5S30(entry-level for low-cost devices), A5S50 (inexpensive chipset, excellent processing of FullHD video stream), A5S90 (can handle FullHD-stream 60fps, but because of its high cost is rarely used in devices).
  • Ambarella A7L - the most modern processors on the core of ARM11 with a frequency of 700 hertz. Can process video stream with resolution of SuperHD 2304x1296 @ 30fps. In addition, they support modern algorithms Wide Dynamic Range and High Dynamic Range, significantly improving the quality of shooting in difficult conditions. The line includes A7LA30D (Full HD 30fps + Wide Dynamic Range), A7LA50D(2304x1296 @ 30fps + 1920x1080 @ 30fps + WDR + HDR), A7LA55 (differs from A7LA50D with WiFI networks support), A7LA70D (can shoot 1920x1080 @ 60fps, Supports Full HD shooting from two channels), A7LS15 (is relevant only for wireless surveillance cameras), A7LA75 (2304x1296 @ 30fps + 1920x1080 @ 60fps + WDR + HDR + support for WiFi networks), A7LA85 (A7LA75 differs from support for dual-channel FullHD recording)
  • Ambarella A9 - based on dual-core Cortex A9 with a frequency of 1 GHz, can shoot with a resolution of 4K 30fps, Full HD 120fps or HD 240fps and has support for WDR and HDR algorithms.
