What are AV wireless transmitters?

AV wireless transmitters are devices that allow both video and audio transmission via radio, without the need to drive cables. They enable the connection of cameras, recorders or any audio-video device to the receiver, making it easier to install in difficult places.

Why use the AV transmitter in the surveillance system?

• No cables: Eliminate the need for AV cables, which simplifies installation and reduces costs.
• Installation flexibility: You can mount the transmitter on the camera, and the receiver in another place – even where the AV cable would be difficult to drive.
• Audio and video transmission: Compact devices allow you to send a full AV signal, not just the image.
• Ideal for monitoring, multimedia projection, presentation or security systems in homes and offices.

Types of AV wireless transmitters offered at MikaShop

The offer includes:

• Sets of transmitter + receiver AV 5.8 GHz: dedicated to CCTV monitoring, provide a stable transmission of image and sound. ([Ewimar AV-500-4HD](https://www.cyberbyte.pl/product/22477/set-to-wire-transmission-video-ahd-cvi.html) – range to ~500 m) :contentReference[oaicite:0]{index=0}
• AV transmitters in the 2.4 GHz band: popular solution for shorter connections – transmitter + AV receiver up to 100 m in a straight line. {index=1}
• Analogue systems for CCTV monitoring: e.g. CAM-Analog2.0 – transmitter and receiver compatible with AHD, TVI, CVI, CVBS. {index=2}
• HDMI transmitters / multimedia: HDMI signal transmission devices (e.g. from the NVR recorder) wirelessly to the HDMI receiver. {index=3}

Key features worth paying attention to

• Transmission range: Radio models offer different ranges – from several dozen metres to several hundred, depending on power and antennas.
• Frequency band: 2.4 GHz provides a better "transmitter", 5.8 GHz can give more speed and less interference.
• Supported signals: Make sure the transmitter supports your video standard (analog, HDMI, etc.).
• Power supply: Check what power the transmitter and receiver requires (e.g. 12 V, USB, etc.).
• Encryption and interference: In an environment with many radio devices it is worth choosing models with good resistance to interference.

Frequently asked questions (FAQ)

Is this AV transmitter delaying?

Depends on the model. Radio transmitters (e.g. 2.4 GHz or 5.8 GHz) usually have a slight delay, suitable for video surveillance — but may be larger than cable connections.

Can I send sound and image together?

Yes, AV transmitters transmit both video and audio (stereo), giving a full A/V signal without cables. Example: AV-500–4HD or Meaty AV240 transmitters.

How much range can the AV transmitter have?

Depending on the power of the transmitter, frequency and environment: the typical AV-500-4HD can have up to 500 m in open space. :contentReference[oaicite:10]{index=10}

Do you need to configure radio channels?

In some models, yes — e.g., Ewimar sets allow for a manual channel selection. {index=11} In others, they are designed to automatically detect and connect.
