RadioEye® A/V transmitters can be used to convert any wired camera into a wireless camera.

 Digital audio/video transmitters 

RE-DTX1 are  a new generation of wireless transmitters for analogue audio/video signals.
Unlike old style transmitters which transform the analogue signal in a RF transmission, this state-of-the-art digital transmitters convert the analogue signal in a digital video and send out a wireless  video stream. The RE-DRX1 receiver re-decodes the digital video in an analogue output in such a way that any PAL monitor or DVR can be connected. The great advantage of digital transmission is the interference-free video quality, which is really equal in terms of  resolution and stability to a hard-wired camera.

 2.4 GHz frequency hopping technology 

RE-DTX1 transmitters operate over the free 2.4 GHz band as most wireless equipment.
In order to avoid interferences with other systems on the same frequency, such as Wi-Fi network for example, these transmitters use FHSS technology (Frequency-Hopping Spread Spectrum).
FHSS technology is a radio transmission technique where transmitter and receiver change their frequency regularly on a random basis.
FHSS allows 3 main advantages:
  Absolute interference-free signal
  Not perturbing other 2.4 GHz systems in the area (wi-fi etc.)
  Not possible to receive the signal without the right receiver
If you are thinking about a wireless CCTV system but you are afraid of interference and low stability typical of analogue wireless systems, do not hesitate any further and buy RE-DTX1. You are not going to regret it.

 ID coded wireless video transmission

RE-DTX1 are high security equipment designed to avoid any access which is not authorized. The transmitter unit communicates only with its own receiver using GFSK modulation and a random ID code technique. The wireless video signal cannot been received by any receiver other  than its own.

 Transmitter and receiver

In order to convert your traditional hard-wired camera in a wireless camera you need to buy one RE-DTX1 transmitter and one RE-DRX1 receiver.
The transmitter module must be connected to the camera using the terminal cable included (3xRCA male: Video + Stereo audio) while the receiver is placed aside the monitor or DVR and provides the same RCA terminals to the output device.
Transmitter and receiver are supplied already paired by factory so no operation is required to make them work together. A pairing procedure is anyway available in case it is required for maintenance purpose.
The transmitter is usually placed near the camera, but it can also be installed faraway if this means avoiding obstacles and improving signal reception.

 Clean noise-free video

If you used in the past analogue wireless transmitters you will be surprised by the RE-DTX1 signal stability. The real-rime video and audio has the same stability and definition of a hard-wired signal. The digital video streaming, Full D1 720x576 video resolution, can be used for any kind of camera even high resolution models.

 Transmission range and number of channels

The maximum operating distance between transmitter and receiver is 150 m. in open air line-of-sight. This performance can be increased by using directional antennas RE-YG1A/2A instead of the standard ones.
The presence of obstacles between the antennas effect the range dramatically, therefore it is recommended to reduce the number of obstacles as much as possible and in any case not to exceed 3/4 walls.
An icon on the corner of the video output indicates the strength of the wireless signal in real time.

FHSS technology allows to install several RE-DTX1 in the same place without they interfere each other. In any case it is recommended not to install over 10 units on the same site.
