IHS on Security Market Trends

IHS publishes Top Video Surveillance Trends for 2016 report. Few quotes:

"4K video surveillance has been repeatedly touted as a major trend in video surveillance for the last 18 months and it can sometimes be challenging to see past the marketing hype. Yet make no mistake, the video surveillance market is going to 4K cameras; it’s only a matter of when rather than if. For 2016, IHS is predicting:
• Volumes of 4K cameras shipped in 2016 will remain low, less than 1% of the 66 million network cameras projected to be shipped globally. We are unlikely to see over million 4K network cameras units shipped in a calendar year until 2018.
• More “4K-compliant” cameras will be launched because of the increased use of 4Kp30 and above chipsets, meaning more cameras adhering to 4K standards, such as SMPTE ST 2036-1.
• Like the HD surveillance cameras, early 4K models offered the resolution at lower frame rates. We’ll see more cameras with a higher frame rate offered, and closer ties to other video standards.

eWBM Launches its 2nd Gen Dual Aperture Depth Map Processor: DR1152

PRNewswire: eWBM launches the DR1152 depth map processor, the successor to the DR1151 dual aperture processor.

The DR1152's predecessor, DR1151 (announced last year), accomplished cost reduction in the depth map processor market by implementing Dual Aperture's 4-color 3D image solution technology which extracts RGB and IR signals from a single image sensor. The DR1152 increases its depth level to 121 (nearly 8 times compared to the predecessor). Unlike the predecessor, which works only with 4-color sensors, the DR1152 now supports both 4-color and 3-color image sensors. eWBM believes that the 3-color adaptation opens a new market sector since it removes the barrier of sourcing only 4-color image sensors. This will expedite time-to-market significantly since widely available image sensors can be bought off the self.

The DR1152 supports a depth image resolution of up to XGA (1024 x 768) at 30 fps or 60 fps at VGA resolution. The technologies such as blur channel depth combining, noise reduction, and edge thinning technology are included in the new product. With all these significant improvement, DR1152 contains less gate count compared to its predecessor.

Heptagon’s current 12 month revenue run rate is around USD 90m at negative operating profitability due to current underutilization of production capacity. Heptagon expects substantial revenue growth over the coming years starting mid-year 2017, based on its existing revenue and capacity pipeline and customer commitments. To prepare for this expected growth, Heptagon has already embarked on a major expansion of its Singapore manufacturing capacity with a total capital investment of more than USD 250m in 2016/2017. The expansion is based on a confirmed customer commitment for usage of the additional capacity and is fully funded from existing cash in the business, requiring no funding by ams.

The transaction combines an upfront consideration in cash and shares with a substantial deferred earn-out consideration. The upfront consideration includes USD 64m in cash from available funds, a capital increase of 15% of outstanding shares from authorized capital (excluding subscription rights) and shares from currently held treasury shares for a total value of the upfront consideration of approx. USD 570m. The earn-out consideration will be contingent on future results of Heptagon’s business over fiscal year 2017 with a potential maximum value of USD 285m. Following the upfront share transaction, current Heptagon shareholders which include financial investors, management, and employees are expected to hold around 20% in ams. The transaction is expected to close within the next three months. estimates the total acquisition price at up to $919 million, or approximately €845 million, if Heptagon hits the targets set for its next fiscal year. "Heptagon has raised tens of millions over the years, including from GGV Capital, Innovations Kapital of Sweden, Innovacom of France, Nokia Growth Partners, High Tech Private Equity, Credence Partners, Jolt Capital, AAC Technologies and Heliconia Capital Management."

Alexander Everke, CEO of ams, commented on the transaction, “Combining ams and Heptagon creates the clear #1 in optical sensing technologies and fast-tracks our innovation capabilities.

Fraunhofer Promises Automotive SPAD-based LiDAR in 2018

Fraunhofer Institute works on SAPD LiDAR for autonomous cars which, in theory, could prevent accidents like Tesla crash:

“A camera’s accuracy depends very much on the lighting available. In this case, it failed. The radar system recognized the obstacle, but couldn’t locate it precisely and mistook the truck for a road sign,” says Werner Brockherde, head of the CMOS Image Sensors business unit at the Fraunhofer Institute for Microelectronic Circuits and Systems IMS in Duisburg.

The researchers have dubbed the new generation of sensors “Flash LiDAR.” They are composed of photodiodes developed at Fraunhofer IMS known as single photon avalanche diodes (SPAD) “Unlike standard LiDAR, which illuminates just one point, our system generates a rectangular measuring field,” Brockherde explains.

“The first systems with our sensors will go into production in 2018,” Brockherde says.
