Wi-Fi Child Presence Detection ( CPD ) Test Video

Unimax CPD uses Wi-Fi signals to detect the situation in the car after the ACC is turned off. Drivers can receive real-time information through smartphone APP, no longer need to worry about leaving children alone in the car.

CPD Development Trend

To avoid repeated cases of heatstroke caused by leaving children alone in the car, the worldwide started to encourage developing CPD and other products with similar function. Therefore, Euro NCAP ruled CPD function as a part of the car safety evaluation. Also, the US Congress launched the Hot Car Act to ask all the new cars should be equipped with CPD to ensure children's safety. Because of these reasons, we can see the importance and universality of CPD will be higher and higher.

CPD Development History

From the Camera CPD, mmWave Radar CPD, to Unimax launched Wi-Fi CPD. Unimax optimized its efficiency and accuracy. What's more, Unimax Wi-Fi CPD is more convenient than others. It can integrate within an original car and notify drivers of the real-time situation in the car through a smartphone APP.

Wi-Fi CPD

Unimax Wi-Fi CPD supports no-blind spot detection. After the ACC is turned off, Wi-Fi- CPD will detect and upload the in-car situation automatically. So users can receive notifications on time.

The Wi-Fi recognition technology can identify whether there is biological movement in the car within one minute, even detect chest breathing movement of 1~6mm. Because of this technology, Wi-Fi CPD can accurately identify a baby's movement in the car.

Advantages of Wi-Fi Presence Detection

The latest directional Wi-Fi detection technology used in UniMax CPD offers high detection accuracy even if the target is covered in a thick blanket. The use of Wi-Fi for presence detection also offers the following advantages:

1. User privacy

Conventional camera CPD, infra-red CPD, or the more recent mmWave Radar CPD all display the human body's features upon detection, leading to privacy concerns being raised by many users. The latest Wi-Fi detection technology used in UniMax Wi-Fi CPD detects and checks for the breathing frequency of the human body. Wi-Fi presence detection offers not just high accuracy and excellent penetration of non-metallic materials. It provides more protection of user privacy as well.

2. No impact on human health

Homes, streets, and even entire cities are now increasingly blanketed with Wi-Fi signals. The safety of Wi-Fi signals is why it has become so ubiquitous. Wi-Fi signals are generally operated on the 2.4GHz or 5GHz electromagnetic spectrum. It is a weak radio frequency signal that will not affect human health even after extended use in an enclosed vehicle. It poses no hazard to human health, making it well-suited to presence detection.

3. No detection blind-spot

Wi-Fi detection has a range of up to 5m. Wi-Fi signals also rebound off metallic materials forming a tightly-knit web that eliminates all detection blind spots within a vehicle. The detection angle of UniMax Wi-Fi CPD can be adjusted in response to the customer’s requirements to maintain its range and accuracy. The increased flexibility makes it suitable for vehicles of all sizes.

4. Hot Spot Integration

An increasing number of vehicles now incorporate an onboard Wi-Fi hot spot. Wi-Fi detection technology can be integrated with the vehicle’s existing Wi-Fi hot spot to reduce the cost of introducing an additional device and make Wi-Fi detection technology more accessible to the general public.

UniMax Wi-Fi CPD Features

UniMax CPD offers many advantages of Wi-Fi detection and others that its peers have found hard to match:

1. Extreme accuracy

The accuracy of Wi-Fi detection is determined by the algorithms used. The proprietary algorithm used with UniMax CPD provides an extremely high level of accuracy that remains unaffected by thick blankets. The Wi-Fi recognition technology can detect biological activity within the vehicle in under one minute. The ability to detect chest movements as little as 1 to 6 mm means even the breathing of babies can be picked up.

2. Easy to install and Low cost

Most other vendors require multiple sensors to be installed for their Wi-Fi CPD. UniMax CPD needs only one device to provide coverage with no blind spots, reducing the cost from the IC design, installing and wiring multiple devices. How that single device is installed can also be customized for greater flexibility.

When most other vendors’ Wi-Fi CPD requires multiple sensors to be installed in a vehicle, UniMax CPD needs only one device to provide coverage with no blind spots. It reduces the cost of the IC design, installing and wiring multiple devices. How that single device is installed can also be customized for greater flexibility.
