Hiqview IP Surveillance Corporation recently launched a new IP camera, the HIQ-5387, aimed at creating a safer public space, especially for public transport areas, such as train stations, subways and airports.

In recent years, the perception of risk in terms of safety and security on public transport has increased. As a result, more and more state and private transport companies are starting to seek help from the fast growing IP surveillance industry. However, many factors within an IP camera can greatly effect the efficiency of that surveillance. Blurry images, the need for constant human monitoring, and the potential for the camera to be tampered with, are just a few of the factors that could result in an ineffective surveillance system.

Hiqview’s new product, the HIQ-5387 is equipped with some impressive features, and has been designed to be a perfect solution for public transport security and safety for 6 main reasons.

First, the camera incorporates a Sony Exmor CMOS sensor. The Exmor technology results in a larger number of pixels and a larger image size, compared to other typical sensors without this feature. In particular, it has a much greater noise-reduction capability. An Exmor sensor is also capable of dealing with analogue-to-digital conversion noise while typical sensors cannot.

Secondly, the HIQ-5387 is designed with a high 60 fps (frame-per-second) feature allowing it to capture more detail from a moving scene. For example, if a low frame rate camera is deployed to monitor a train station, the movement of every passenger would look odd. For instance, a man would move from the platform suddenly into the train, instead of step by step. This is because a low frame rate camera cannot catch every moment. If the application requires recorded video for law enforcement or evidencial purposes, then the more moments and details that are captured the better. The HIQ-5387, on the other hand, is capable of capturing clear images of moving objects via the 60 fps feature. With 60 fps, things move just as smoothly as they appear to move in front of the human eye.

Third, the Intelligent Scene Analysis. HIQ-5387 has been designed with 3 major intelligent scene analysis algorithms: Intelligent facial detection, Tamper detection,and Digital Image Stablization (DIS).

The Intelligent facial detection function helps people to locate and verify human presence. When watching over an open area, such as the airport halls or the car parks, usually we don’t care if a stray dog walks by, but we do need to focus on people who enter the monitored area. The facial detection function distinguishes human faces from other objects and if necessary pinpoints a specific face from a recorded database.

The Tamper detection feature will activate when for example, the lens of the camera is covered or re-directed, or is being effectively blinded by dazzling light, or even if the focal distance is changed. This featurewill automatically send alarms to notify the on duty guards to take timely action.

The Digital image Stablization (DIS) feature will prevent the capture of blurry images on a moving train or vehicle due to the vibration of the movement or different surfaces. HIQ-5387 has DIS technology built-in, which calculates the impact of the objects’ movement and uses that data to adjust which pixels on the image sensor to use to minimize the impact of the train or vehicle shaking.

Fourth, the advanced true-wide dynamic range (T-WDR) function is capable of sustaining quality images in challenging lighting conditions. The T-WDR within the HIQ-5387 is effective when monitoring strong backlit or dimly lit environments. Suppose in the afternoon, the sun is shining directly in through the window of the airport, and a man is standing in front of that window. Because of the strong backlight, the man’s face would be too dark to identify. The true-wide dynamic range (T-WDR) technology from HIQ-5387 will use different exposures for different objects, making the light contrast much lower, and is designed to clearly show the features of the man’s face.

The HIQ-5387 also includes a 2D+3D noise reduction function. A surveillance system effected by image noise could be almost be rendered useless, and it can be caused by many factors, such as power source interference, heat, and dim lighting sources. The 2D+3D noise reduction function sharply reduces image noise, resulting in not only clearer images, but also smaller video file sizes.

Finally, the robust housing of the HIQ-5387 is designed as IP66 water-proof, which means it is effective in wet and dusty outdoor environments, such as streets, car parks, or public squares. The HIQ-5387 also has a vandal-proof design to avoid severe harm from any incidental or malicious attacks. The semi-sphere exterior perfectly blends into a ceiling, making the HIQ-5387 disguisable as something other than a surveillance camera. This type of camouflage can greatly reduce the possibility of the camera being damaged.
