CONNECTING A SERIAL INPUT DEVICE TO A DS SYSTEM

Before you configure a serial input device connected to a DS system, complete the following steps:

1.Determine baud rate, parity, stop bits, and size of serial string for your alarm system.

2.Determine the text string that you want to trigger recording. The following examples are text strings you might want to use: 10:23:15 DOOR140 FORCED <cr > <lf>

10:23:20 READER141 VALID ACCESS<cr> <lf>

10:24:40 DOOR140 RESTORED <cr > <lf>

NOTE: Carriage return “<cr>” and line feed “<lf>” are the characters that Digital Sentry recognizes as end-of-line characters.

To configure serial inputs on a VAU, complete the following steps:

1.Open DSAdmin from Start>Programs>Integral.

2.Click on the VAU in the DSAdmin directory tree and select the Serial Inputs tab.

3.To activate a COM port, highlight it and click Add. Then highlight it in the assigned ports list and enter serial input information on the following five tabs:

General: This tab requires the following information:

Maximum Line Size: The maximum size of a string coming from the alarm panel. A string longer than this many characters will indicate an error.

End of Line Characters: A character, such as a carriage return, that indicates a line is complete.

Description: A description of the COM port.

Active: Activates the COM port.

Port Settings: Enter the alarm panel settings here, including the COM port, baud rate, parity, and stop bits.

Reset Text: Enter all text string segments the alarm panel sends to indicate that an alarm is reset. The instance of one of these segments in a string is recognized as an alarm reset. After you enter each segment, click Add.

Required Text: Enter text string segments that must be present to cause Digital Sentry to recognize an alarm. If the panel sends multiple similar strings for the same alarm, only the string with one of these segments is recognized. After you enter the text, click Add.

Alarm Text: Enter all of the the text string segments the alarm panel sends to indicate that an alarm is occurring. The instance of one of these segments in a string is recognized as an alarm. These segments are used to trigger recording in certain zones that you will configure. After you enter the text, click Add.

To determine which cameras should begin recording when certain text strings are sent through specific COM ports, complete the following steps:

1.Use DSAdmin to create a Zone using instructions found in the Digital Sentry System Software Operation/Configuration manual (C3661M) or DS NVR and DS NVs System Software Operation/Configuration manual (C3663M). This zone should include all cameras that begin recording when the text strings are received by Digital Sentry.

2.Select the zone in the directory tree and select the Serial Input tab.

3.Select a COM port, enter the text that the alarm panel will send during a particular alarm, and click Add. When the alarm panel sends this text through the designated COM port, the zone’s cameras begin recording.

To test the serial device configuration, complete the following steps:

1.In DSAdmin, expand the directory tree to Configuration Parameters.

2.Highlight the Services/SerialLog parameter. This parameter creates a log file of data read on the COM ports. Enter a value of 1 to create a log in ASCII characters, or enter a value of 2 to create a log in hexadecimal format.

3.Send the text strings configured for the COM ports.

4.Check the log file (in C:\DigitalSentry\logfiles) to verify that the information sent through the COM port was received by the DS system.

C3662M specifications

The Pelco C3662M is a state-of-the-art camera designed for robust surveillance and exceptional performance in various environments. Built for security applications, this camera features advanced imaging technology that ensures reliable monitoring and high-quality video capture.

One of the main features of the C3662M is its high-resolution image sensor. This sensor captures clear and crisp images, even in low-light conditions. With a resolution of 2 megapixels, the camera delivers detailed footage that can be crucial for identification purposes. The camera is capable of generating high-definition video streams, providing security operators with the clarity they need to assess any situation effectively.

The C3662M also incorporates advanced technology such as Wide Dynamic Range (WDR), which allows it to perform exceptionally well in scenes with contrasting lighting. This feature ensures that both the bright and dark areas of a scene are captured with excellent detail, making the camera particularly useful in environments like parking lots or entryways where lighting conditions can vary greatly.

Another critical characteristic of the C3662M is its low-light performance. Equipped with infrared (IR) capabilities, the camera can operate effectively in complete darkness, making it an ideal choice for 24/7 surveillance. The IR illumination allows the camera to capture clear images even when there is no visible light.

The C3662M is also designed for versatility in its deployment. It supports various mounting options and configurations, enabling users to install the camera in various locations, from indoor environments to outdoor settings. The rugged construction of the camera ensures it can withstand adverse weather conditions, making it suitable for use in challenging environments.

In terms of connectivity, the C3662M is compatible with various video management system solutions. It can easily integrate into existing security infrastructures, allowing for seamless operation and monitoring.

With its combination of high-resolution imaging, advanced WDR technology, and versatile installation options, the Pelco C3662M stands out as a premium choice for security applications. This camera addresses the needs of modern surveillance with reliability, ensuring that users can maintain peace of mind through effective monitoring capabilities.
