4MP dome with HDR and built-in IR, for indoor applications.

For customers who have challenging lighting conditions and need a flexible field of view, the SE4 Indoor IR Dome from March Networks® integrates IR LEDs and High Dynamic Range (HDR) to deliver high-quality images in a variety of lighting conditions, from bright light to complete darkness. And the adjustable zoom and focus settings allow you to get the perfect field of view. 


  • 4MP dome for indoor applications
  • High Dynamic Range
  • Integrated Smart IR for illumination in total darkness
  • Hallway mode feature
  • Convenient Low Bit Rate (LBR) setting helps reduce storage and bandwidth usage

Key Benefits

▼ High Dynamic Range (HDR). The camera blends the best parts of several separate exposures together to combine the most focused, well-lit, and colorful parts of the scene.

▼ Integrated Smart IR. The built-in LEDs provide uniform illumination in total darkness, which means users will see highquality, low-noise video from 100 feet away. Additionally, the camera automatically adjusts the intensity of the IR LEDs to compensate for the distance of an object, so the object is not overexposed when it gets too close to the camera.

▼ Save money on storage and bandwidth. The camera’s low bit rate (LBR) setting reduces storage and bandwidth usage by 50% or more in most applications; streams can drop below 1Mbps at 4MP (15 fps).

▼ Image is always in focus. The camera can focus automatically based on zoom position, allowing it to remain in constant focus.

▼ Remote zoom and focus. No need to manually zoom and focus from the top of a ladder. Installers can zoom in and out remotely with the click of a mouse.

▼ Hallway mode. To capture vertically-oriented scenes, such as hallways and corridors, the camera provides a 90° rotation so images are created vertically, maximizing the field of view in narrow situations.

▼ No need for pipe threader on-site. The EMT mount is perfect for high ceiling drop installations; it allows the dome to be affixed directly to a pipe (e.g., PVC) without the need to thread the pipe.

Get the perfect field of view

Capture high-quality surveillance video in challenging lighting conditions with the SE4 Indoor IR Dome. Combining High Dynamic Range (HDR) and built-IR Smart IR, the camera delivers sharp, low-noise images of objects up to 100 feet away. The camera automatically adjusts the intensity of its IR LEDs based on the distance of the object to provide just the right amount of illumination.

Save money on storage and bandwidth

The SE4 Indoor IR Dome features a convenient Low Bit Rate (LBR) setting that can reduce storage and bandwidth consumption by as much as 50% in most applications. Streams can drop below 1Mbps at 2MP (15 frames per second).
