Virtually unlimited expandability for the SecurityProbe . . . connect up to 600 sensors to one unit!
Filed under: General, Ravica News, SensorProbes, environmental monitoring
The majority of Ravica customers that I talk with are looking to monitor a small number of specific environmental conditions—sometimes that is monitoring the temperature and humidity in the data center or detecting water leaks in a second home. For these applications, the BitSight2 and BitSight8 sensor probe models are great environmental monitoring solutions at an affordable price. However, there are times when a customer has a need to monitor many, many more conditions and input devices. For these customers, I’d like to cover the expandability features of the newest SecurityProbe model.
In the past, some of the SecurityProbe advantages included; advanced notification options, great video capabilities and the ability to connect up to 8 sensor probes per unit. The newest SecurityProbe retains all of these great features and adds four RJ-45 expansion ports to the front of the box which allows the connection of up to four expansion units. There are two expansion units options available: the E-opto16 and the E-sensor8.
With the E-opto16, you get 16 isolated dry contact inputs. A typical application for this expansion module would be to connect the dry contact to alarm panels and create custom alerts for each of the alarms. For example, one could have a dry contact connected to the fire alarm, another to the security alarm, and another to the AED cabinet. Each dry contact could then be set up to automatically call the respective emergency operator, in these cases the fire department, police, or paramedics. An unlimited number of E-opto16’s can be daisy-chained to accommodate up to 600 different dry contact inputs.
If you are more interested in increasing the number of intelligent sensors that can be monitored, there is the E-sensor8 that adds 8 sensor ports. Like the E-opto16, the E-sensor8 can be daisy-chained to allow the monitoring of up to 600 sensors through a single SecurityProbe. The two expansion units are also compatible with each other , giving the user complete control in designing the combination of dry contacts and sensors that works for their unique needs.
If you’d like more information on these new expansion modules, give us a call at 207.324.8173. We’d love to help you design an environmental monitoring system that does just what you need it to do.

Setting up voice/SMS notifications with Skype
One of the great things about a web-based environmental monitoring system is the ability to set-up notifications in a wide variety of ways to make sure that emergency situations do not go un-noticed. This saves on the response time that can easily be the difference between averting a disaster and having to face substantial losses of data or property. The SecurityProbe’s user friendly web-interface provides a number of options for setting up notifications for every sensor available in the Ravica line. One of the newest features is the ability to set up voice and SMS text notifications using Skype.

Physical Security for Data Centers
Data centers house some of the most valuable and irreplaceable assets for any organization. For this reason, physical security is of the utmost importance when designing a data center. Depending on the size and budget of the organization, physical security measures can include everything from solid floor-to-deck concrete partitions to biometrics screening.
There should also be a number of sensors in place that can detect when anyone, authorized or unauthorized, accesses the data center. The following 5 tips show how Ravica can offer effective solutions for that final line of defense. Read more

Setting up e-mail notifications for the SecurityProbe camera
Security cameras made the news in a big way last weekend, when a security breach at the Newark Liberty International Airport led to the discovery that one of the TSA surveillance cameras had been broken for six days leading up to the incident. Six days! Now that gives a real sense of security in these uncertain times, doesn’t it? The breach, which authorities were notified of by an alert passerby, caused a 6-hour lock-down and possibly cost the airport over $100,000, according to a report in The Star Ledger. Thankfully, this breach apparently was caused by a man walking his girlfriend to her flight and not a potential terrorist, however, it certainly exposed the gaping holes in the security protocol at one of the busiest airports in the US.
I have no idea what sort of back-up notification system for camera failure the TSA has set-up, but after reading about the Newark incident, I wanted to find out what kind of notifications are available for cameras connected to the Ravica SecurityProbe. Read more

What you can do about Christmas tree fire hazards
Filed under: Security Monitoring, smoke detector, temperature monitoring
The holiday season is finally upon us. As usual, with the cold weather comes turkey dinner and Black Friday sales - but that’s not all! If your family is anything like mine, the first thing you do after properly digesting your stuffing and waking from your Tryptophan coma is put up that glorious Christmas tree. There is really no better indication of the impending holiday season than a well lit and beautifully decorated tree.
I am a fan of the good ol’ fashion fake tree. Nothing says Happy Holiday’s like the smell of, well… plastic. But as I understand it, there are some 33 million American homes that go the natural route with their tree selection. However, improperly hydrated Christmas trees can pose a very real safety concern. According to the U.S. Fire Administration, “Christmas trees account for 200 fires annually, resulting in 6 deaths, 25 injuries and more than $6 million in property damage.”
Ravica SecurityProbe Picture Log
Filed under: Intelligent Sensors, Security Monitoring, SensorProbes, motion detector
Today, I started working with a software company who wanted to keep track of their employees that work very early or very late hours. In
general, it wasn’t a bad thing. They just wanted to make sure that the people coming into the building to work, were the people that should be. This company had already purchased monitoring and security equipment from us in the past.
This company just added a new international sales department. The work hours for the new employee were going to be 4:00am to 1:00pm. They wanted to know if they could utilize the picture log to record when people go in and out of the front door. They also wanted to limit the time frame for these pictures.
I did a bit of research and found out the answer was yes! You can set a time frame on the camera motion sensor and you can have the picture emailed or stored on the FTP server. Now, they would get an alert and a picture when someone came through the door.
At this point, they could figure out who came through the door. They then wanted to know if too many people were going through the door during the early morning hours. To do this, we used a Syslog/Eventlog application that allows you to set a threshold. Each time an image was taken with the camera, an alert would be sent to the Syslog/Eventlog manager. If a threshold was met, let say five, then an email would be sent to the security office.
The customer was excited and wanted to implement this in the coming weeks. I can’t wait to see how it comes out.

Remote weather stations use Ravica SensorProbes
Filed under: environmental monitoring, humidity monitoring, temperature monitoring
I love finding new ways people are using our probes! I just finished a call with a university up here in the north land, who wanted to use our probes in their remote data station. The remote data station is part of a funded study to determine the changing weather conditions in the area.
The problem is that the grant they received would fund the weather monitoring equipment, but not the equipment that would run the unmanned station. The good news is that their technology budget would cover the BitSight8 and the required sensors.
They needed to be able to monitor temperature, humidity, airflow and security. The customer explained to me that since this was an unmanned station, knowing if anyone has opened the server room door was extremely important.
We spent some time talking about the various environmental conditions and how they can affect the servers. He was surprised how the environmental conditions would effect the station’s performance.
The environmental conditions of the area can change throughout the year. The winters can drop below zero, while the temperature during the summer months is in the 90’s with high humidity. Monitoring for humidity is vital; condensation on a circuit board can kill a machine. Having a monitor in place is absolutely vital.
We then went over the alerting and reporting ability of the probe and how this unmanned station’s IT center would be fully monitored. I also spent some time explaining the SecurityProbe and how it would alert them when someone opened the door. I am looking forward to the install date. I hope that it is in the summer. I hate snow!

How to reduce false positives and frequent temperature alerts
Filed under: Data Center, SensorProbes, environmental monitoring, temperature monitoring
Previously, I wrote about managing the sensitivity of your motion detector to prevent or reduce false positives from normal environmental motion, while maintaining the security that the motion detector sensor provides. I thought I would elaborate on the subject by providing some tips on how to limit frequent alerts and false positives for any environmental monitoring sensor, like temperature.
As I mentioned before, the “continuous time to report,” or “rearm” as it is called on the SecurityProbe, are an excellent way to say, “Don’t alert me as soon as a sensor goes into a ‘warning’ or ‘critical’ status. However, if it has been in a ‘warning’ state for 30 seconds, let me know.”
Another way to limit how often – or how easily – your BitSight2 or SecurityProbe sends you Skype alerts or emails is to adjust the “reading offset” field, which can be found under each sensor’s advanced settings. The “reading offset” forces the sensor’s reading to move over or under a certainly value before generating an alarm. So basically, if your temperature upper “warning” threshold is set to 80 degrees and your “reading offset” is set to 2, and the current temperature is 79 degrees, then your SensorProbe will not alarm until the temperature drops another degree.
This prohibits the sensor from being right on the verge of a threshold and consistently bouncing between two statuses. You don’t want 20 emails in your inbox because the temperature in your data center is exactly on your threshold and wobbling back forth between “normal” and “warning.”
Another way of limiting alerts during off hours, maintenance windows or times when you are not really concerned with the readings breaching a threshold is to use the calendar feature. Please note that the calendar feature is available only on the SecurityProbe line of SensorProbes.
Block off times that you do not wish to receive alerts and the SecurityProbe will ignore the breached thresholds during those time frames. Perhaps you don’t want to receive alerts during the day, because people are always present and aware of the environmental conditions in the locations you are monitoring. However, maybe you want the temperature of your walk-in cooler monitored at night, when no one is in the building.
Whatever the reason, these are two great tips for better managing your alarms. This ensures that your alarms are more meaningful and so when you or you staff see an alert from your BitSight2 or SecurityProbe, you know it is time to act.

Remote UNIX server shutdown with SecurityProbe
Today, I thought I would take the time to highlight one of the features that makes the SecurityProbe environmental and security monitoring system so special. Where the BitSight line of probes are great entry level systems, the SecurityProbe line has many additional features that really set it apart; as well as support for the thermocouple sensor and the power monitor.
So what feature am I detailing then? Let’s talk about the server shutdown feature. Basically, the SecurityProbe can be configured to automatically shutdown a server when an event occurs. An example might be that you want to shutdown a cluster of servers based on the status of an AC voltage sensor. When you get an alert that the power went out and you are running on battery backup, this could keep your non-essential equipment from sucking up all the remaining juice.
Wondering how you configure this on your SecurityProbe? You are in luck! Just follow the instructions below.
Setup of UNIX shutdown action and notification
1. Create new Action
- Select the “Notifications” page, then “Add Action” from the left panel.
- You can rename the action in the “Action Name” box.
2. Select “Shutdown” from the “Action” drop down menu.
3. Select “UNIX (SSH)” from the “OS Platform” drop down menu.
4. Input your servers IP address into the “Remote Server IP” box.
5. Input your log in username into the “Remote Server Login Name” box.
6. Click on “Add Server”. Add additional IP’s if needed. Click “Next”.
7. Click “Reset Public Key” (If you already have a Public Key, skip this step and proceed to step number 11 below).
8. After clicking “Reset Public Key” a new Window will then pop up, press “Generate”.
9. The unit will now generate a new public key. It will normally take approximately 1 to 3 minutes for the system to generate the new public key, so please be patient.
10. After the public key has been generated, press “Use This Public Key”.
11. Open a Telnet or SSH session to the unit.
cd ~/.ssh
ls
rm known_hosts
12. Make sure to delete the know_hosts file to ensure generating a new list of hosts when using this command shown above.
ssh @
When
is User name in server
is IP address of server
13. Then connect to the server by using this command shown above.
cd ~/.ssh
cat > authorized_keys
#copy public key from web interface and press (for putty can press by right click)
#press Enter button and press Ctrl + c for exit cat command
14. After connecting to the server, create an authorized_keys file by using this command shown above
15. Then disconnect from the server and connect to the unit.
ssh –I /flash1/user/shutdown_notify/dsskey.db @
When
is User name in server
is IP address of server
16. Now test the public key by using this command shown above.
17. Return to the units web interface and click “Next”.
18. You can now set the other settings in the Shutdown action and click “Next”.
19. You can also enable a shutdown message to be sent by first choosing “Enabled”, then entering your message in the “Shutdown Message” box, then clicking “Finish”.
That’s all there is to it. Stay tuned for more SecurityProbe exclusive feature spotlights.

Measure extreme temperatures with a thermocouple sensor
Filed under: SensorProbes, environmental monitoring, temperature monitoring
The Ravica temperature sensors can certainly save you a lot of headaches when it comes to maintaining a certain temperature range in your data center, storage facility or even health care facility. However, what if you have an application that requires you to measure the temperature outside of the capabilities of our standard temperature sensor? For instance, maybe you are monitoring the temperature in a very low temperature freezer; or perhaps you are in charge of making sure a boiler room doesn’t get too hot.
The standard temperature sensors are designed for accurate temperature readings from -55° Celsius to +75° Celsius or -67° Fahrenheit to +167° Fahrenheit. So our boiler room scenario might be a problem if the sensor needs to be at, in or near the boiler itself. This is where the thermocouple sensor comes in handy.
The thermocouple sensor is capable of accurately reading temperatures in dangerous or harsh environments or in heavy industries, such as petrochemical and metal processing. Temperature ranges on the thermocouple sensors are -270° Celsius (-454° Fahrenheit) to 1372° Celsius (2501° Fahrenheit). Ravica uses a type K thermocouple, which is very commonly used in these industries.
The thermocouple sensor is compatible with the SecurityProbe line of sensor probes. So anyone planning to add a thermocouple to their setup will want to plan accordingly. The BitSight line is an excellent entry level series of products, but is not compatible with some of the more advanced sensors, like the thermocouple and the power monitor.
So don’t get discouraged if your current temperature monitoring solution can’t take the heat. A SecurityProbe and a thermocouple sensor can get the job done.
