Small wireless Full-HD video transmission without latency

Ideal solution for industrial applications looking for wireless solutions without latency, such as UAV, elevators, pipe inspection robots, mechanical robots, hoists. Any setting in which improved movement freedom, or reduction of cabling is required.

Wireless video transmission without latency -15AT-W

Full-HD wireless AHD/TVI/CVBS transmission is the ideal step up to Full-HD while replacing CVBS wireless modules. The skoopia 15AT-W wireless AHD/TVI/CVBS transmittor and receiver unit is capable of up to 500 meters wireless communication for 1080p30/25 AHD/TVI signals.


Key advantages AHD wireless versus WiFi wireless:

  • No latency

  • Affordable

  • Small

  • Lightweight

  • Straightforward connection (video in / video out)

It is a superior solution in any setting in which AHD or TVI is used as technology (for the known reasons of long transmission, easy cabling and no latency) where freedom of movement or avoiding difficult connectors is an issue.


To meet above challenges, and the known skoopia small size camera implementations demanding small size transmission units, we have made the 15AT-W wireless AHD video transmitter as small as possible (26mm x 46mm) and have also included the smart option that one can attach up to six AHD wireless video transmittors without latency to a single receiving unit. Moreover, we included a super small size u-fl (IPEX) connector for the antenna (default is SMA, which is sizeable), further emphasizing skoopia's focus on on super small high resolution video solutions without latency.


AHD wireless is the next revolution in any setup wanting to create freedom of movement, reducing complexity of cabling (slip rings, replacement requirements etc), or avoiding recalibration/ re-initiation of a video setup in a plural video environment.


Characteristics of wireless video transmission wihtout latency

  • Transmission over 500 meter

  • Low power mode for easy implementations

  • Full-HD streaming AHD/TVI 1080p30/25, but also 720p or CVBS

  • No latency

  • 5.8 GHz frequency

  • Affordable (pricing meets CVBS wireless pricing)

  • Up to 6 Full HD (1080p30) transmissions to 1 receiving unit parallel.

Wireless AHD is the Full-HD solution for existing CVBS applications requiring wireless transmission but want to step up to Full HD.

There are multiple applications that could benefit from wireless & Full-HD video transmission without inducing additional latency. Here are two examples helping to identify beneficial situations applying wireless AHD.


Avoid cable carrier or drag chain

Typical application areas are found in situations where significant movements are made over long distances, requiring video cable to be included in the setup. Successful examples of such situations: Cameras in elevators, cameras in hoists or cranes avoiding long moving ropes, typically guided by cable carrier or drag chain.


Avoid slip ring

Slip-rings are required if applications demand rotation freedom. However, slip rings, certainly in longer cabling instances and higher video frequencies, have a significant impact on the total video signal. Robot applications requiring multiple degrees of freedom and low latency high quality video greatly benefit of replacing multiple slip-rings with one wireless AHD solution.


Avoid changing connection

In applications in which single camera output is viewed, but plural camera systems will be used and exchanged often, up to six wireless connections can be established to a single receiving unit, further limiting difficult connection changes and instant exchange of the connection to be viewed.


The industrial wireless AHD/TVI/CVBS solution works seemlessly with all industrial AHD cameras, and particularly with the skoopia AHD/TVI/CVBS cameras.


board cameras

  • single board 14mm x 14mm Full HD AHD/TVI camera - skoopia 21C14AT

  • single board 26mm x 22mm Full HD AHD/TVI/CVBS camera - skoopia 21C26AT

block cameras

  • 10x optical zoom Full -HD AHD/CVBS block camera - skoopia 20Z10S-NF

  • 20x optical zoom Full -HD AHD/CVBS block camera - skoopia 20Z20A (no longer available)

  • 30x optical zoom Full -HD AHD/CVBS block camera - skoopia 20Z30A

The receiving output can be fed directly to the skoopia AHD native monitors (e.g. skoopia M215AT) or skoopia DVR (e.g. the skoopia D20AT-1 with smart overlay capability).
