HK Speed Camera Alert is an Android app developed by Hongkong Post Hong Kong SAR Government, and it is available free of cost. The app belongs to the category of Utilities and Tools, and is designed to assist motorists in Hong Kong to avoid speed camera summons.

The app provides instant alerts to motorists when a speed camera is detected ahead. The alert is triggered when the camera is approximately 1-3km away, giving the user sufficient time to slow down their vehicle and avoid any penalty. The app is smart enough to only alert when the camera is in front of the driving direction, prioritizing driving safety.

One of the standout features of this app is that it works in the background, even when the phone is in sleep mode, and allows the user to use other apps simultaneously. The app also saves battery consumption by turning on the screen only when an alert is triggered, and going back to sleep mode after passing the camera spot.

The app requires GPS to be turned on for precise camera and user coordinates, but internet or data connection is not required, except when switching to Map view. The app also provides a human voice alert and a camera location in Map view.
