10 latest technological upgrades for speed domes

10 latest technological upgrades for speed domes

In 2013, speed domes entered into the arena of ultra high definition. Asmag has compiled a list of 10 technological upgrades that have made speed domes the new favorite in the projects market.

Full HD Network Speed Dome Cameras
Speed domes require special installation and have higher maintenance and operational costs. After upgrades to specifications and efficiency were made, mainstream resolution has been substantially upgraded to 20-30x optical zoom at 1080p. Additionally, the price difference between network and analog is not big, which has allowed network cameras to become the preferred technology for projects.

CMOS Night Vision Optimization
Nowadays, cameras equipped with CMOS light sensors are comparable to those with CCD sensors. The optics industry has strengthened the effectiveness of CMOS sensors in low light; camera manufacturers have raised the light sensitivity on their cameras, allowing speed domes to provide clear images even in low light, as well as filter light given off by street lamps. In addition, speed domes have already built-in ICR and WDR, which allows for clear images.

Supports 4 Streams, 3 Compression Formats, and Mobile Viewing
Dual streaming no longer meets the needs of the market. Nowadays, speed domes equipped with the best processing chips are able to simultaneously export images onto 4 streams; high-end cameras support multiple compression formats (H.264, MJPEG, and MPEG4). Other cameras can support either 1080p at 30fps or 720p at 60fps. The above specifications satisfy users' requests for real-time viewing, recording, and mobile viewing, as well as meet image quality and compression format requirements. Among these requests, mobile viewing has become an essential—it is also the newest weapon for users to control PTZ functions from their mobiles at any time.

Built-in SD Card Automatically Saves and Recovers When Disconnected
Supporting SD/SDHC cards is now a standard feature on speed domes. When the network disconnects, images are immediately stored at the front-end of the camera, and if other problems arise it can make a temporary backup. Once the network has been reconnected, the camera will automatically be restored back to the image before the disconnection occurred.

More Presets; Tilt Angles Expand Scope of View
The cruising preset is the speed dome's most unique characteristic and duty. Previously, speed domes had 128 presets, but as technology has developed this number has grown to 256 with 8 automatic cruise settings. Moreover, minute horizontal and vertical movements of only 0.1 degrees can be made, giving more energy to speed domes for operations and use. Regarding installation of speed domes near walls and the issue of ceilings causing blind spots, improved lenses allow tilt angle movements of plus or minus 20 degrees providing a wider field of vision.

Panoramic Thumbnails Allow for Intuitive Operations
With speed dome networking, users can use a mouse for operations. Within three minutes of being turned on, the speed dome automatically conducts a 360 degree panoramic and 180 degree vertical scan and then turns the images into small thumbnails. From the thumbnails, the users can move and select from the images and the lens will immediately move to the selected area; a mouse can also be used to mark a preset point, as well as set up a group and cruising route. The preset point can then be zoomed in or out on and the speed of movement between two points can be adjusted individually.

Calibrate Images from Deviating at Any Time
After a while, the substantial movement of the speed dome will cause disparities to slowly show between the images the lens presents and its actual position. However, it is now possible to set two times for the camera to automatically calibrate and immediately conduct some fine tuning so that the disparities are lessened. Speed domes will store in its memory the set points it was previously moved to without needing any special set up so that the next time it can use the previous memory for its cruising path.

Distinct Auto Tracking Speeds
Auto tracking technology is already mature. It can follow a moving object at the speed it is moving and accelerate and decelerate accordingly.

Audio Detection Makes 3D People Counting More Accurate
3D people counting can detect a three-dimensional person's head, body, and movement. It can also accurately count the total amount of people in its vicinity, as well as determine and record direction and path of movement, allowing the speed dome's IVA to correctly carry out its management tasks.

Due to requirements for government projects, audio detection alarms were developed. Currently, speed domes can only detect audio—when a sound goes over the preset it triggers an alarm; however, over time audio detection will evolve. Eventually, speed domes will not only be capable of recognizing different categories of sounds, but also be able to put the image together with the sound, as well as be able to trace the origin of the sound.

Pairing With Fisheyes for All-Around Surveillance
As the technology for fisheye cameras mature, there are already companies providing fisheye lenses and speed domes as an integrated solution. This allows the users to use the manual or automatic tracing mode to more accurately lock onto suspicious persons or objects from the panoramic image.

The panoramic map taken with the fisheye lens can be used with the speed dome to match and pair images during installation. The user can then immediately use the on-site panoramic image to control the speed dome, which not only allows the user to see a more complete picture, but also allows them to trace every detail within the panoramic image.
