Automation Control Circuitry

What is TTL? TTL stands for Transistor-to-Transistor Logic, where the “logic” determines which values are high and low. Standardized common TTL circuits operate with a 5-volt power supply. A TTL signal is defined as low when the voltage is measured between 0.0 V and 0.8 V with respect to the ground terminal, and high when… Continue reading Automation Control Circuitry

RS-422 Advanced PTZ Menu Control

In version 4.1 of the ExacqVision software, advanced RS-422 PTZ controls were implemented for Pelco-D and American Dynamics domes. One of the advanced controls allows the operator to open the dome’s internal menu to display menu choices in an onscreen display (OSD) embedded in the dome’s video stream. A cursor can be moved up and… Continue reading RS-422 Advanced PTZ Menu Control

What analog PTZ protocols does Exacq support?

Exacq supports the following RS-422 and RS-485 PTZ protocols. With each protocol, you can specify the baud rate, data bits, stop bits, parity, flow control, and maximum line length.

Connecting an ExacqVision Hybrid System to a Pelco Coaxitron Translator for Analog PTZ Control

ExacqVision Hybrid servers have the ability to integrate with Pelco Coaxitron CXTA 9760 devices. This allows customers with existing Pelco PTZ cameras that are controlled through the coax with the Coaxitron protocol to be controlled using ExacqVision software. The CXTA accepts the Pelco 422 protocol from the ExacqVision server, and it outputs the data over… Continue reading Connecting an ExacqVision Hybrid System to a Pelco Coaxitron Translator for Analog PTZ Control

What is the difference between a Group and a View?

Views and Groups are similar in that both of them are logical groups cameras based on more than just the server they are connected to. The major difference is that a View also defines a layout of the cameras onscreen.  Because it specifies a layout, the maximum number of cameras in a View is limited… Continue reading What is the difference between a Group and a View?

Does the ExacqVision Client Support Multiple Monitors?

Yes, ExacqVision Client supports multiple monitors. We have tested up to four VGA monitors from a single workstation. Typically, a user will run one instance of the ExacqVision Client per monitor. Because decompressing video is CPU-intensive, we recommend one core per Client for the best user experience. To drive up to four VGA monitors, we… Continue reading Does the ExacqVision Client Support Multiple Monitors?

What is the VGA Acceleration Mode feature on the Client page?

The process of decompressing and displaying hundreds of video images per second is processor-intensive. It is possible to use the capabilities of modern display adapters to offload the main workstation processor from some of this work.<br> The ExacqVision Desktop Client tries to automatically determine the best operational mode and colorspace for the available display hardware.… Continue reading What is the VGA Acceleration Mode feature on the Client page?

How do I change the listening port number for exacqVision Server?

By default, the exacqVision Client communicates with exacqVision Servers on port 22609. If your network does not allow port 22609, or if you need to forward the port on multiple exacqVision systems, you can change the exacqVision Server’s listening port number. To do this, complete steps detailed on this page. NOTE: The exacqVision Default Ports… Continue reading How do I change the listening port number for exacqVision Server?
