Busch-Watchdog 220 MasterLINE select

To ensure the business keeps operating. For special tasks.

The Busch-Watchdog not only looks good. It also impresses with its inner quality. High-quality, intelligent technology adds a new dimension to safety. And it gives one a feeling of safety, inside and out. The intelligent Busch-Jaeger movement detectors miss nothing. They respond instantly when needed. For example, they detect immediately when a light is to be switched on or off, and they are a reliable signpost in the dark. These high-quality detection systems guarantee uninterrupted surveillance in all areas. They ensure that your sleep is peaceful, chase away thieves and switch the light on and off when you are on holiday.

Smart and alert.

The small disc-type surveillance zone makes the Busch-Watchdog 220 MasterLINE especially attractive for applications in the commercial sector. The detection range is 220° and the coverage 16 meters to all sides. At an appropriate mounting height it additionally offers an area 2 meters in height in which no detection is carried out. However, if a person approaches, it responds immediately. It additionally offers functions such as continuous light On, continuous Off, presence simulation or storage of the brightness switching threshold, which can be activated/deactivated via the IR remote control. It is suitable for mounting on walls and ceilings.

All loads up to a maximum of 3,680 W/VA can be connected to the movement detector.The models are, like all Busch-Watchdog units, easy to operate with practical functions such as operating mode, twilight setting, switch-off delay and short-time pulse. Also the automatic range stabilisation remains constant during different outdoor weather conditions.

Overview of colours.

The Busch-Watchdog 220 MasterLINE select is available in the modern colour white.

Detection range.

This movement detector has a detection range of 220°. The coverage is 16 meters to all sides. It has a disc-shaped detection level with continuous detection.

Mounting options.

01 Wall mounting.
The classic installation. The Busch-Watchdog movement detectors can be easily and quickly installed. In the classical position on the wall, for example. One of the most frequent installation options.

02 Ceiling mounting. All good things come from above. If the Busch-Watchdog is to be installed on the ceiling, there are two versions. From the bottom for a wide detection range. Or with a corner adapter, to be able to position the device correctly.

Comfortably controlling all functions.

With the practical IR remote control you are always fully in charge of safety and comfort. The settings can be handled easily without a ladder or an electrical installer. For example, brightness switching threshold, presence simulation or continuous light On/Off.
Link to Busch-Remote control IR


  • Ideal for free-standing houses
  • Detection range of 220°, 16 m to all sides
  • The device can be protected against direct dismantling by means of additional screw connections.
  • The retaining hole is compatible with all previous Busch-Watchdog models
  • Important functions such as continuous light On, continuous Off, presence simulation, saving of the brightness switching threshold can be deactivated/activated with the IR remote control without a setting on the device.
  • Remote operation and remote parameterization, further settings/functions can now be disconnected/connected via the IR service remote control.
  • Saving of energy: The time for the forced switch-off depends on the set switch-off delay; however, it is limited to a maximum of 90 minutes.
  • Signalling of detection to make commissioning easier or for diagnostics purposes
  • Cabling is easy to install without clamping
  • No gaps in detection, homogenous, large detection range
  • As creep zone protection and switch-on when stepping out of the door
  • Automatic range stabilisation. In case of changing outdoor conditions the Busch-Watchdog keeps the range constant.
  • Automatic interference suppression
  • Presence simulation (while on holiday, for example). At the arrival of twilight, continuous light is activated and after approximately 11:30 p.m. the watchdog function.
  • All loads connectable, maximum 3,680 W/VA

Additional functions of the Busch-Watchdog 220 MasterLINE model:

  • With one detection level
  • Detection with animal access
  • No floor or rearfield detection




Precise surveillance.

The ceiling installation is suitable especially for the precise surveillance of warehouse thoroughfares and parking areas. The detection range operates like a curtain. It is also ideal for private buildings in the country where wild animals move around. They don't normally come so close to the house that they enter the detection curtain. This prevents false triggering.
