No need for separate RGB and IR cameras in remote patient monitoring

Camera-enabled Remote Patient Monitoring (RPM) or virtual nursing systems have helped mitigate healthcare challenges like monitoring patients during COVID-19 and managing the scarcity of medical resources by providing continuous 24/7 remote monitoring.

Cameras were initially used to detect the presence or absence of patients and their basic movements. However, recent camera technology advancements, along with AI and ML integration, have led to the rise of a comprehensive RPM system capable of movement monitoring, fall detection (even fall prevention), and facial expression analysis for pain assessment

One such technology is the RGB-IR camera, which is increasingly being used in RPM systems. RGB-IR cameras can capture both white light RGB and monochrome IR images, eliminating the need for two separate cameras. These cameras prove to be a cost and space-efficient alternative to traditional cameras.

Eliminating the need for two separate cameras in RPM

Camera-based remote patient monitoring systems generally use two methods for round-the-clock monitoring:

1. Two separate cameras for day and night monitoring
2. A single camera that uses an IR-cut filter to block the IR light during the daytime

On the one hand, using two cameras results in the devices becoming power-consuming, expensive, and cumbersome to handle. On the other, mechanical lens filters used in cameras are prone to wear and tear, resulting in reduced product lifetime.

With the help of continuous efforts, engineers have developed RGB-IR cameras which prove to be a superior alternative for the above solutions. RGB-IR cameras eliminate the need for two cameras as well as mechanical lens filters, offering both day and night imaging in a single device.

Therefore, using RGB-IR cameras in Remote Patient Monitoring or virtual nursing systems eliminates the need for two separate cameras for RGB and IR imaging.

Benefits of RGB-IR cameras in remote patient monitoring or virtual nursing

Day and night mode switching

RGB-IR cameras use lenses with dual bandpass filters, unlike standard lenses that use IR-cut filters, to allow both visible and NIR light to reach the sensor. It enables RGB-IR cameras to capture images in both RGB and IR modes, eliminating the need for mechanical lens filters, which are typically used in traditional cameras.

Enhanced imaging in no-light conditions

RGB-IR cameras have sensors that have dedicated IR pixels on their surface. The IR component of RGB-IR cameras enabled clear and detailed imaging even in total darkness. It can be crucial for night-time monitoring, as it enables healthcare providers to observe patients without the need for external lighting that could disturb their rest.

Compact form factor

By integrating the functionality of RGB and IR imaging into a single device, RGB-IR cameras offer a compact form factor. Such a design reduces the need for two cameras, simplifying integration into RPM systems and saving valuable space. The streamlined design makes the equipment more manageable and contributes to a more efficient setup.

Reduced power consumption and costs

Integrating RGB and IR imaging into a single device ensures lower power consumption when compared to using separate cameras for each function. The reduction in power usage translates to decreased operational costs and contributes to the sustainability of remote patient monitoring systems. By combining two functions into one device, RGB-IR cameras help lower energy consumption while reducing the long-term expenses of equipment maintenance and operation.

Simultaneous RGB and IR imaging

RGB-IR cameras excel at capturing colour (RGB) and infrared (IR) images simultaneously within a single frame. The dual imaging capability provides a full view of the patient’s condition by integrating visible light details with infrared insights. It ensures a more complete and accurate assessment of the patient’s health, as both types of data are available in real-time for enhanced monitoring.
