What is IR Intensity on a Blink Camera?

When setting up a Blink camera, users can access and adjust the IR intensity through the camera settings on the Blink app. Offering three preset configurations – low, medium, and high – the IR intensity determines the brightness of the camera’s IR illuminator.

Infrared Light

Infrared (IR) light is a type of invisible light used by security cameras, such as Blink cameras, to illuminate dark areas and provide clear images during low-light conditions. Blink cameras use IR LEDs to emit infrared light, which is then reflected off objects and surfaces to create a readable image for the camera’s sensor.


Blink cameras feature an 850nm infrared LED light that provides illumination in dark environments. The IR intensity on a Blink camera refers to the brightness of the IR illuminator and can be adjusted to suit various lighting conditions.

Blink Cam allows you to choose between three preset configurations for IR intensity:

  • Low
  • Medium
  • High

Adjusting the intensity is simple, and is done through the camera’s settings within the Blink app. By finding the right setting, you can improve the quality of the video footage captured in low-light environments.

The infrared sensor in Blink cameras is designed to detect the amount of ambient light in the environment. When the light levels drop below a certain threshold, the camera automatically enables the IR LEDs, allowing it to capture images in complete darkness.

Additionally, you can manually control the infrared light from the app, turning it on or off as needed.

In summary, IR intensity on Blink cameras refers to the brightness of the IR illuminator, which is responsible for providing clear images in low-light conditions.

Through the Blink app, you can adjust the intensity according to your needs, leveraging the infrared LED light and sensor to improve your camera’s overall performance in darker environments.

Night Vision Settings

Blink cameras are equipped with Infrared (IR) technology to provide clear video in low light conditions. The IR Intensity setting plays a crucial role in determining the brightness of the infrared illuminator for night vision recording, enabling users to enhance the quality of their recordings while optimizing battery life.

The IR intensity can be configured between three preset options – low, medium, and high. You can adjust the intensity based on the lighting conditions to achieve the best results.

To access IR controls, follow these steps:

  1. Open the Blink app and tap the camera settings icon located above the camera’s thumbnail on the app Home screen.
  2. On the Device Settings screen, select Video and Photo.
  3. Control the IR settings using NIGHT VISION and IR Intensity.

Night Vision Mode

The NIGHT VISION mode in Blink cameras allows users to control the activation of IR LED lights:

Night Vision ModeExplanation
OffThe IR LED never turns on, and night images appear dark.
AutoThe camera automatically activates the IR LED based on the lighting conditions in the environment.
OnThe IR LED remains continuously activated for night vision, even in daylight.

It’s important to note that leaving night vision mode on continuously may affect battery life. For optimal camera performance, it is recommended to use the auto mode so that the IR LED activation adjusts as per the ambient light.

In conclusion, the night vision feature in Blink cameras, when paired with the appropriate IR intensity settings and night vision mode, ensures clear video recording in low-light conditions while conserving battery life.

Camera Settings

Blink cameras offer different IR intensity settings to ensure optimal performance in various low-light conditions. To access IR intensity settings, navigate to the Device Settings screen and select “Video and Photo.”

IR Sensitivity

There are three preset configurations for IR intensity on Blink cameras: low, medium, and high. To achieve the best results, adjust the intensity according to the lighting conditions in the camera’s environment.

IR SensitivityExplanation
LowSuitable for environments where there is some ambient light available, and the area being monitored is relatively small
MediumTypically used for medium-sized areas with moderate lighting conditions
HighBest for larger areas or when the lighting conditions are extremely low

Adjustable IR Settings

Blink cameras have an 850nm infrared LED light designed to provide clear video even in dark settings.

Along with IR intensity settings, Blink cameras also offer control over the Night Vision mode:

  • Off – The IR LED never turns on, and night images appear dark
  • On – The IR LED is always on, and all clips appear black and white
  • Auto – The IR LED turns on when the visible light is low, such as at night

These features make it easy to fully customize your Blink camera’s IR settings based on your specific needs and the surrounding environment, resulting in clear and detailed nighttime footage.

Motion Detection and Security

PIR Motion Sensor

Blink cameras use a PIR (Passive Infrared) motion sensor to detect movement. This technology works by detecting changes in infrared radiation emitted by objects, like humans or animals.

PIR motion sensors help in conserving battery life since they only activate the camera when motion is detected, making them an efficient choice for security purposes.

To customize motion detection settings in your Blink camera, navigate to Device Settings for each camera to control motion detection, zones, retrigger time, and more. By enabling motion detection and setting up activity zones, you can make sure your security camera system only records and sends alerts for the most important events.
