Digital Audio/Video transmitters

SDTX1E 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, these state-of-the-art digital transmitters convert the analogue signal in a digital video, by sending out a wireless video stream. The receiver 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

SDTX1E transmitters operate over the free 2.4 GHz band as most wireless equipments.
In order to avoid interferences with other systems on the same frequency, e.g. Wi-Fi networks, those transmitters useFHSS technology (Frequency-Hopping Spread Spectrum). FHSS technology is a radio transmission technique where transmitters and receivers 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.)
• Impossibility to receive the signal without coupling the right receiver.

 ID coded wireless video transmission

SDTX1E are high security equipments designed to avoid any unauthorized access. 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

SDTX1E package includes 2 units: transmitter and receiver with similar design. 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 purposes.
The transmitter is usually placed near the camera, but it can also be installed far away if this means avoiding obstacles and improving signal reception.

 Clean noise-free video

If you already used analogue wireless transmitters, you will be surprised by the SDTX1E signal stability. The real-rime video and audio have 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 SYG1AE/2AE instead of the standard ones.
The presence of obstacles between the antennas affects 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 SDTX1E in the same place without they interfere each other. In any case it is recommended not to install more than 10 units on the same site.
