Question   How the storage capacity calculation is done in BVMS Configuration Client and VRM Monitor?   Answer   The calculation of the storage capacity is done in different way in Configuration Client and VRM Monitor:  In BVMS Configuration Client Capacity (GB) stands for the available physical capacity of the storage, as calculated and provided by the storage vendor (for example NetApp). In VRM Monitor – under Target Overview – Total is listed the number of all available blocks multiplied by the size of the blocks that is by default 1GB. This calculation concerns the logical storage and depends on the way the storage is used (for example how many Luns are imported in the system).   See also: Video Storage Calculator web site   Useful: How is the storage capacity calculated for DSA E-Series E2800 12-bay (RAID 6)? ...

Question   Which Bosch encoders and decoders are compatible with BVMS?   Answer   Until some years ago, new released cameras, encoders, domes and decoders that were introduced into market after a BVMS release could not be connected to an existing BVMS version because these cameras where not known to the BVMS. In the BVMS 4.5.1, a new concept was introduced. This concept treats Bosch video encoders and decoders as generic devices, and automatically recognizes specific device functionality (for example the number of streams, relays and inputs). Based on this information, unknown device is added to the system and can be used by the operator. The attached document provides a detailed description of this functionality. ... View more

Question   What are the best practices for surge and lightning suppression?   Related Products These practices apply to all Bosch IP cameras installed outdoors.   Answer   IP Cameras Surge and Lightning Suppression (Best Practices) Cameras installed outdoors are typically exposed to surges, transients, and lightning. The wiring and installation details in this guide are based on common practices used at sites to ensure proper surge and lightning suppression. This drawing is an example of the best practices to follow during design and installation. This information is applicable to any IP camera, but the mounting hardware will vary between models.   1 Indoor main building. 2 Network switch with shielded ports and grounding as recommended by the manufacturer. All network cables must be terminated with shielded RJ45 connectors. 3 Surge suppression for indoor equipment at cable entry. 4 Outdoor rated surge suppressor with shielded RJ45 connections that must be mounted as close to the camera as possible. Connect the ground per the manufacture’s installation manual. 5 Install Cat5e/Cat6 shielded Ethernet cable such as F/UTP shielded cable with twisted pairs (often referred to as FTP) or S/UTP braided shield with twisted pairs (often referred to as STP) with shielded RJ45 connectors. The cable must be routed through a permanently earthed metal conduit. Earth grounded across the entire span.  The cables must be a maximum length of 100 m /328 ft). Power and signal cables must be in separate conduits with the correct physical separation distance between them. Refer to Additional wiring guidelines. 6 Outdoor rated midspan with shielded RJ45 connections. Ground the metal conduit to the midspan per the camera/midspan installation instructions 7 Equipment enclosure with AC power source for the midspan. 8 Optional outdoor rated network switch or patch panel. 9 Connect the Bus Bar to the Equipment Grounding Electrode. All equipment must be bonded to this common bus bar. 10 Lightning Rod. – Refer to Lightning rod, down conductor, and electrode 11 Down Conductor. Refer to Lightning rod, down conductor, and electrode. 12 Lightning Rod Grounding Electrode. Refer to Lightning rod, down conductor, and electrode and Separate Grounding Electrodes. 13 Equipment Grounding Electrode. Refer to Separate Grounding Electrodes.   Additional wiring guidelines Here are some typical recommendations for the minimum physical separation distance between the Cat5e/Cat6 shielded Ethernet cable and high voltage/EMF sources. Use these guidelines or follow the equivalent code appropriate for the country/region. Use shielded cables for alarms, audio, or any other connections when applicable. The Cat5e/Cat6 shielded Ethernet cable provides the proper grounding when using a POE power source. It is not necessary to connect a separate ground conductor to the pipe interface board. Lightning rod, down conductor, and electrode The lightning rod down conductor connects directly to the grounding electrode. Refer to NFPA 780, Class 1 & 2, UL96A, and to the equivalent code appropriate for the country/region. Follow the lightning rod manufacturer’s installation instructions. Separate Grounding Electrodes Some standards call for a common electrode for the equipment bus bar and the lightning rod. Refer to NFPA 780, Class 1 & 2, UL96A, and to the equivalent code appropriate for the country/region. Metal Pole Grounding If a metal pole is used, Refer to NFPA 780, Class 1 & 2, UL96A, and to the equivalent code appropriate for the country/region. Camera Housings and Mounts Use only Bosch mounts listed on the specific camera’s data sheet. Follow all grounding for the camera housings and mounts per the installation manual.   A frequently asked question is how to ground the parapet mount. Please refer to the following article: How to ground the parapet mount (Outdoor Installation of Bosch IP Cameras & POE Midspan)? ...

Question   How can I set, clear and check Bosch encoder virtual alarms via CGI?   Answer   Related Products All Bosch encoders running firmware 4.0 and above   You can use virtual alarms within encoders as a trigger to have other events take place. This is an example on how to integrate 3rd party devices/software to trigger an event to take place on the encoder. This event could be used to change any variable via ATSL (Alarm Task Script Language) - example below Virtual Alarms via CGI Set Virtual Alarm: http://160.10.92.40/rcp.xml?command=0x0a8b&type=F_FLAG&direction=WRITE&payload=01&num=1 Clear virtual Alarm: http://160.10.92.40/rcp.xml?command=0x0a8b&type=F_FLAG&direction=WRITE&payload=00&num=1   Check virtual Alarm: http://160.10.92.40/rcp.xml?command=0x0a8b&type=F_FLAG&direction=READ&num=1   Return result : 0 refer to virtual alarm is set 1 refers to virtual alarm is clear Virtual Alarms in ATSL if (VirtualAlarm(1)) then Relay(1) := true; if (!VirtualAlarm(1)) then Relay(1) := false;   ⚠️ ATSL Documentation ...
