Cloud Archiving Systems

Optical Jukebox Library in the Cloud

By Dennis Gallen


cloud-archiving-illustrationWe define archival information storage as a mechanism for writing data that can’t be modified or erased, storing information for a very long time (over 50 years), and providing easy retrieval.   Information archiving has evolved over the last century; from paper, to microfilm, and then to optical discs in jukebox libraries.  


Optical discs were introduced in the early 1980s.  The Write Once Read Many (WORM) 12-inch discs, introduced by Sony and other companies, provided archiving media that allowed organizations to archive their paper information to optical storage.  CD-ROM discs were introduced by Philips and Sony in 1985. A couple of years later Sony introduced DVD-discs and Magneto-Optical discs.  Jukeboxes or Libraries were designed to handle over 500 discs, creating a complete archiving storage system.  Blu-ray discs were introduced by Sony in 2003, and became the archiving media standard.

Comparison of IP Intercoms

Pros and Cons of Different types of IP Intercoms

By Bob Mesnik


Intercom conceptThere are a number of different IP intercoms available.  In general they are used to notify you that someone is at the door.  The intercom allows you to talk to the person at the door, and in some case see them.  It is also used to release the electric lock at the door.  The intercoms are wired to the local area network. Some models can also connect to your smartphone.    


In general, these IP intercoms help you control entry to your home or organization.  They also provide additional security to organizations that use door access control readers.  Authorized people can gain access using their credentials or even using biometrics (like a fingerprint reader), while visitors can be monitored for controlled entry. These complete systems enhance your total security, assuring a safe environment in this uncertain world.  Here is a comparison of the different systems available.

Surge Protectors for Network Attached Devices

How to Protect Your IP Security Systems from Power Transients

Surge protectors protect network attached devices from power transients.  Lightning is only one of the many power disturbances that can damage these IP devices.   There are a number of surge protectors available that can be used to minimize the damage from these power transients.


Anything that’s attached to your network, can be affected by power surges.  For example, your computer, door access system, IP camera, network switch, and router can be affected if there is a power spike.  Transients can occur not only on the power lines, but also on the data connections.  Surge protectors, from Ditek, are used to suppress the affect of these power spikes.


Here’s a summary of the surges and spikes that can occur, and how you can protect your equipment.

How IP Intercoms Communicate with Smartphones

IP Intercoms for Mobile Applications

By Bob Mesnik


IP intercom-illustrationSmart IP intercom devices are making it easier to control access to your home, business, school, or any other organization.  They use your smartphone to see the person at the door, talk to them and allow entry (or not).


There are single-button intercoms and multi-tenant intercoms. Both versions have built in IP cameras. The IP intercom systems can use local intercom servers as well as remote cloud servers to provide the communication path between the intercom and the smartphone. These systems utilize various protocols such as VoIP SIP protocol, audio over IP, IP video, or other protocols to establish the connection between all the devices.


Here’s how the latest IP intercoms work.
