Many large modern monitors and televisions have a horizontal resolution of 4,000 (4K) pixels. When using certain interfaces to display video, 4K resolution is either unsupported, or it can be displayed only at a refresh rate of only 30 Hz, resulting in choppy video. However, 4K resolution can be displayed at 60 Hz over interfaces… Continue reading exacqVision Compatibility with 4K Resolution Monitors

exacqVision and Heartbleed
In April 2014 a Security Advisory was issued by the OpenSSL project notifying the public of a serious vulnerability in the encryption software used by a large number of companies. (For detailed information, visit http://heartbleed.com/.) Exacq Technologies took immediate action to assess how this affects its products. <br> exacqVision uses OpenSSL for a few functions, but… Continue reading exacqVision and Heartbleed
Arecont Camera Video Loss with Large Frame Sizes
Issue Some cameras are capable of creating large frame sizes. There are two issues that can be encountered by unreasonably large frame sizes. As frame size increases the likelihood of the exacqVision recorder throttling increases. A frame size > 4MB will cause exacqVision to display “Acquiring Video” message instead of the actual video stream. This… Continue reading Arecont Camera Video Loss with Large Frame Sizes
Validating ExacqVision Video (also known as Watermarking or Authentication)
The validation standard used in ExacqVision is known as HMAC, for Hashed Message Authentication Code, and uses a cryptographic hash and secret cryptographic key. HMAC is used by ExacqVision to verify the integrity of exported video. The ExacqVision Client software calculates and writes out the message authentication code (MAC) during file export. The ExacqVision ePlayer… Continue reading Validating ExacqVision Video (also known as Watermarking or Authentication)
