  • Connect the receiver directly to the monitor using a short coaxial cable for testing.
  • Change the operating channel.
  • Check the power supply and try another power adapter if necessary.
  • If several sets operate in parallel, start and test one set at a time.

A common cause is a low-quality power supply with voltage fluctuations. Use a high-quality regulated power supply, either transformer-based or switched-mode.

The wireless signal is usually too weak because of distance or obstacles. Use external antennas, optimise the location or add a relay point to bypass obstructions.

This can result from interference from parallel digital transmission systems. Change the channel and position the receiving mast or antenna several metres away from digital sets.

  • Check the power supply for stable voltage.
  • Adjust the video signal level at the transmitter using the VR potentiometer.
  • Check impedance and termination; use a 75-ohm terminator if required.
  • If the signal is too weak, use a video amplifier or equaliser.
  • For UTP/twisted pair, use suitable video baluns.

The number indicates optical zoom. Higher zoom, such as X25, improves identification of people or number plates from greater distances.

A camera with strong optical zoom, such as X25, and infrared night vision is generally recommended to capture details at longer distances.

Yes. Remote access is available from a PC, tablet or smartphone. For vehicle use, a stable LTE connection with a router and external antenna helps ensure reliable controls and live video.

Yes, depending on the system, via SMS or a web panel, for example. An optional deep-standby mode can extend standby time.

Yes. Depending on configuration, continuous or event-triggered recording is available, for example for movement, line crossing, intrusion or object removal.

Generally yes, subject to camera compatibility, including ONVIF and model support. A compatible NVR/VMS or supported camera model is often recommended to access all features.

This depends on the camera's power consumption and usage, including infrared illumination and zoom. External batteries or a 230 V mains supply can support longer operation.

Using a quick-mount bracket: insert and secure the camera in the holder. The bracket is first attached to a mast or facade with steel straps or wall plugs, depending on the surface.

Depending on the setup, buffering or local storage may be available. Synchronisation or transmission can resume after the connection is restored.

First check the SIM and network, including possible provider restrictions, and the router or modem settings. A watchdog feature with ping checks and automatic reboot can help reset the system after a fault.
