Industrial CVBS cameras

skoopia offers numerous industrial cameras supporting CVBS, but all skoopia industrial cameras have a minimum resolution of 2 MP. The smaller cameras support CVBS in two aspect ratios for making the transition to Full HD easier.

The following solutions are provided by skoopia to make a smooth transition from CVBS to Full HD, changing elements in the entire video chain one by one.

  • Industrial DVR accepting AHD/TVI/CVBS video input, while offering smart overlays

  • Industrial Monitors displaying AHD/TVI making use of the full 4:3 screen without distorting the video.

  • Industrial CVBS cameras offering video output with 4:3 aspect ratio (classic CVBS) and 16:9 aspect ratio (often called Wide-CVBS) allowing to make use of 16:9 monitors.

The industrial DVR and Industrial Monitors are described in a special section. An overview of the industrial CVBS cameras offering 4:3 aspect ratio as well a 16:9 aspect ratio (Wide-CVBS).

All other industrial CVBS cameras offer the default 4:3 aspect ratio output for CVBS. The above two cameras are also the two cameras that allow intermixed usage of VISCA and PELCO protocol. No need to select the protocol. 

All other industrial CVBS cameras support VISCA and PELCO, but require upfront selection of the protocol. 

Industrial CVBS camera | Digital zoom

All of skoopia's industrial cameras are based on sensors with a minimum of 2 MP. As such, they provide a surplus of more than 8 times as much data as a regular CVBS sensor would do (regular CVBS sensor provides approximately 0,3 MP). This surplus allows for digital zoom without resolution loss if the industrial camera is operated in CVBS mode. Naturally, the industrial camera needs to support digital zoom, but if it does, it provides a benefit to have digital zoom without resolution loss up to 2.5 x as a minimum (depends on the sensor resolution and aspect ratio). 

This benefit can be very suitable for board level cameras, but also if one wants to integrate a small block camera in CVBS mode with significantly higher integral zoom without resolution loss (a 10x optical block camera with a 2MP sensor would become a 27x block camera  wihtout resolution loss.

Industrial camera | Dual output

Several of skoopia's industrial cameras offer dual output. This implies that the cameras offer two video signals parallel. This can be beneficial if e.g. an operator requires an immediate visual assessment without any latency, while in the back ground image analysis takes place using the second video output. Underneath you find the cameras that provide dual video output.

Industrial CVBS camera | Upgrade to AHD, SDI or IP?

Upgrading of OEM solutions is not so trivial. Numerous aspects have to be considered, next to the industrial camera's  form, fit and function. Also cabling as well as video capture, display and recording needs to be considered. 

Although every application is different, the underneath flow chart should help you with your choice if you are considering to make the transition from CVBS to Full HD. 

Industrial CVBS camera | Development outlook

Although the market for CVBS is remaining substantial, it is very small if compared to the markets and applications that drive the sensor and camera development, being security and more recently automotive.

As indicated, low bandwidth, affordable pricing and low latency have kept numerous applications making use of industry cameras or medical cameras using CVBS cameras. Although AHD and SDI cameras where already available, only recent developments (skoopia being one of the leading companies) providing direct control commands (VISCA, UtC, I2C) as productive tools for industrial AHD cameras and SDI cameras have provided the benefits of Full HD or even higher resolution, removing the last issues (productivity of the operator / surgeon). 

Such key developments have been made in tight collaboration with the engineering departments of the leading DSP suppliers, i.e:

  • NextChip for AHD/TVI/CVBS cameras

  • Eyenix for the HD-SDI/EX-SDI/CVBS cameras

More recently, alternate vendors are experimenting with SoC (System on Chip: Sensor and DSP integrated in one chip) solutions for Industrial AHD cameras, only requiring a small transmission chip as a driver for the AHD video signal. 

skoopia has adopted the first ever Full SoC (having Sensor, DSP and Transmission unit integrated in one chip for the 21C14AT, which allowed us to build such a small camera (14mm x 14mm single board). 

The outlook for industrial cameras will more and more depend on the developments in the automotive sector - away from the security sector-, as this application is vastly adopting large volumes of cameras, with cameras requiring similar to industrial camera characteristics.

 

In the coming 5 years, it is expected that CVBS-only cameras will be no longer available. Combined CVBS with AHD or CVBS with SDI cameras easing the transition to Full HD are expected to remain at least till 2035.

Industrial CVBS camera from skoopia have no WDR in CVBS mode

Although quite some industrial cameras in skoopia's portfolio offer WDR (True DOL WDR, making use of two images with different shutter times, not to be confused with Digital WDR, which is just a silly option), WDR is not available in CVBS mode. 

This can be explained. All sensors used in skoopia's portfolio are able to run 60 or 50 frames per second. To output a streaming video, only 30 or 25 frames per second are required. Making use of 2 frames for 1 WDR image is therefore possible for all modes running 30 or 25 frames per second. 

WDR is therefore available for all modules in which 

the sensor supports the WDR mode

the output is 30 or 25 frames per second, i.e. 1080p30/25 or 720p30/25.

WDR is not possible for the following modes (if supported by the DSP)

1080p60/50, 1080i60/50, 720p60/50, 720i60/50 and CVBS.

Industrial CVBS cameras, with NTSC or PAL have an interlaced video output (PAL: 768x576i50, NTSC: 640x480i60). Since the sensors used (both Panasonic MN-series and Sony Starvis Exmor R series) can only provide up to 60 frames per second, WDR is not available for any interlaced video, also not for CVBS.
