Composite RCA Video Audio Over Coax Cable Extender KitComposite RCA Video Audio Over Coax Cable Extender Kit   
Now you can easily extend your analog video/audio feeds from DVD player or CCTV surveillance camera through the coax antenna cable to a TV, video monitor or DVR at distance. This coax cable extender kit allows long distance transmission of standard video and audio signals traveling through CATV type coaxial cable while maintaining crisp and clear picture and sonic quality all the way till the receiving ends.

Coax cable can be used to carry multiple video/audio, radio/antenna signals or other signals together with various frequency ranges in same cabling such as the cable TV distribution. 

With help of this coax cable extender kit, users can easily combine multiple surveillance cameras to be linked together through one single coax cable for transmission far over 800 meters (2000ft) without losing picture and sonic quality. 

This composite A/V over coax cable extender kit uses single CATV type 75 Ohm broadband coaxial cable, such as dual or quad shielded RG-6 or RG-59, to extend the TV display or video monitor at distance without a repeater needed. 

This video audio extender kit is very suitable for public broadcasting applications in classroom, conference rooms or video surveillance for hospitals, airports, restaurants, hotels, conference rooms as well as in secure military and commercial setup.

Setup Diagram For Composite RCA Video Audio Over Coax Cable Extender Kit

Easy Installation
This video/audio over coax cable extender kit contains a local transmitter and a remote receiver module. They are very easy to be set up. Simply connect the video and audio output from devices such as CCTV camera, DVD player,
Digital TV converter to the coax transmitter unit first, which will modulate both the audio video source signal into coax type with selectable TV channel frequency based upon the choice of the installer.

Then connect the coax output from the coax transmitter module to the coax receiver unit via RG-6 or RG-59 coaxial cable. Coax receiver module will revert the coax TV channel frequency signal back to separate composite video audio format for connection with monitor display or recording by DVR.

[Note]: This product has NTSC and PAL version. The default shipment will be NTSC version. For international customers who need PAL version for the setup, please leave us a reminder note in the purchase order or order form.

Cost Efficient Solution For Distance Signal Transmission
Coaxial cables offer a low-cost solution for long distance signal transmission line. Coaxial cable is widely popular and already wired in many households, corporate buildings and campus due to the aerial, CATV/MATV, satellite installation or closed-circuit television (CCTV) for surveillance and distance education.

Coax cable can be used to carry multiple video/audio, radio/antenna signals or other signals together with various frequency ranges in same cabling such as the cable TV distribution. 

With help of this coax cable extender kit, users can easily combine multiple surveillance cameras to be linked together through one single coax cable for transmission far over 800 meters (2000ft) without losing picture and sonic quality.

RCA Video Audio Distribution Over Coax
This new innovation allows users to create customized TV broadcast system by transforming the standard outputs from any A/V device into private closed circuit TV channels. Any TV hooked up through the coax cable can access those new private channels using the remote.

This video audio over coax cable extender kit can be widely deployed in various applications such as:

  • Closed-Circuit Private Channels:
    Regular home users can use this product to combine free-to-air digital broadcasts and satellite channels into your own ca
    ble system. Instructors or campus can use this product to create new closed-circuit channels and broadcast the multimedia content through internal RF system for information and training purposes.  Parents may also use this modulator to replace or override the inappropriate or unwanted TV channels for the benefit of young audience.
  • Source Device Sharing:
    Single A/V device or media player can be shared by multiple TV displays. All TVs connected through the same coax cable can view the new private channels created by this modulator.
  • Digital Signage: 
    A/V output from signage player can be modulated and extended by this device for creating new information channel and transmitted over multiple TV displays at remote location with very low cost in the setup.
  • Video Surveillance:
    Video and audio signals from CCTV surveillance camera can be
    installed far apart from the DVR and presented on a unused TV channel.  

One Transmitter For Multiple Coax Receivers
One coax transmitter can work with multiple coax receivers at the same time. Additional coax receivers can be purchased separately for large setup.

Adjustable Video Audio ControlRackmount Kit For Composite RCA Video Audio Over Coax Cable Extender Kit
Both the A/V to coax transmitter and the coax to A/V receiver modules are featured with adjustable controls for audio/video signal and gain adjustment. Users can manually adjust the signal input/output level for easy integration with existing cable system. So the picture stability will remain the same as the original A/V input signal for the remote end display with minimum distortion and noise-free with full brightness and contrast.

Last Channel Memory
The coax transmitter and receiver unit will retain the setting after being powered off manually or power outage event.

Easy Expansion
Multiple units can be cascaded together at any time. Users can add additional transmitter and receiver units in the setup for accommodating more audio/video source devices without adding new cables since the signal can be cascaded from the transmitter though multiple receivers.

Rack Mountable Design
This extender kit is rack mount ready. There are rack-mounting holes on the front panel. The optional rack-mount kit can be purchased separately to have multiple of these modules installed together on a 1U, 2U or 3U rack chassis.
