Ravica Environmental Monitors Begin Where Mayberry Ends
Filed under: environmental monitoring, Intelligent Sensors, motion detector, SensorProbes, smoke detector, water leak monitoring
Growing up in a small town had some advantages, including a feeling of security. For example, when our family would leave town on vacation, the police department kept an eye on our home. Patrol cars drove by our house periodically, day and night, ensuring that our home and possessions were safe. In this way, it was if our small town was in the very capable hands of our own Andy Griffith. These days, law enforcement departments don’t necessarily have the resources to protect property this way.
Fortunately, we can have that sense of trust with a Ravica environmental sensor. Ravica security monitors placed in your property can alert you to the presence of property hazards like smoke and water. While you are away, you can still feel secure knowing you will be alerted to hazards as soon as they happen.
Ravica’s Motion Sensor Cameras Prevent Tremendous Drain on Networks
Filed under: environmental monitoring, Intelligent Sensors, motion detector, Security Monitoring
It seems the need for preventative monitoring is everywhere.
Last week I noted a discussion with an associate who lost data due to a water leak in a data center. Not long after that discussion, I had a conversation with an IT Manager regarding business structure. During our conversation, he mentioned that his building’s security officers recently called him with complaints of slow internet connectivity. He used his company’s NetFlow monitoring tool to find the source of tremendous internet bandwidth streaming. Through the NetFlow Analyzer, he narrowed the focus to one specific security camera and realized the camera was constantly streaming images of an empty hallway. This streaming was pumping pictures to the network server and causing huge delays.
He further used his Scrutinizer Analyzer Read more
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

Ravica SecurityProbe Picture Log
Filed under: Intelligent Sensors, motion detector, Security Monitoring, SensorProbes
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.

How to reduce false positives and frequent temperature alerts
Filed under: Data Center, environmental monitoring, SensorProbes, 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.

Help desk: How sensitive is your motion detector sensor?
Recently, I blogged about using the motion detector sensor to increase the security presence of your data center. Well, expanding on the topic, I thought I would answer one of those frequently asked questions I get from customers using the motion detector to beef up security. “How do I keep the motion sensor from being set off by very small movements?” The answer – you can adjust the sensitivity of the motion detector using the sensor status filter.
The sensor status filter allows you to enter a time delay that must occur before the sensor changes status, thus filtering out noise in the signal. This avoids unnecessary sending of notifications, as fluctuations can occur during normal working conditions.
To find this setting, go to the Motion Sensor Settings page of the web interface, and click on the sensor status filters button. Change the “Continuous time (secs) sensor is to report” field to some value other than zero. 1 second is a good place to start, but it all depends on your specific working conditions.
At any rate, increasing the continuous time to report field a bit can help keep you from getting false positives and give a little extra room for normal environmental shifts.
Stay tuned to the Ravica blog for more helpful environmental monitoring tips.

Motion detector sensors add security to your data center
Filed under: environmental monitoring, motion detector, Security Monitoring
While working on a project recently, I was taught the importance of the motion detector sensor in the security monitoring toolset. The SecurityProbe is the first place to look for monitoring the temperature, humidity and other environmental variables of your server room, while at the same time adding a security presence with the pan-tilt dome camera support. However, for some customers with smaller or unconventional data centers, the budget for security and environmental monitoring can be in the hundreds of dollars, not thousands.
That’s where the motion detector comes in. It works not only with the SecurityProbe line, but with the BitSight2 and BitSight8 as well. The beauty of the motion detector sensor is that you can daisy chain up to 10 sensors to work off a single intelligent sensor port. And at just $125 per sensor, users can easily cover a good sized data room with motion detection and still have an extra intelligent sensor port on even a BitSight2 for monitoring temperature and humidity.
So keep the motion detector sensor in mind when speccing out a new data room or when adding security monitoring measures to an existing one. It is a very affordable alternative, when it is simply not possible to have eyes and ears on your secure locations.

3 Tips for Data Center Security
We put a high focus on protecting the data center from environmental disasters, like extreme temperature and humidity, as well as water leaks and poor air circulation. However, there are other considerations to be made in keeping the data center safe, like physical security conditions. Is all of the sensitive equipment being protected from unauthorized personnel?
Of course the first order of business is to set standards and procedures that make those in charge of data center security aware of exactly what is acceptable clearance and what is not. However, as is true for almost any kind gateway, mote, or minefield, people will find their way around. So there must be systems in place that keep us alerted to situations that are potentially hazardous.
The Ravica SecurityProbe can increase the level of data center security by providing insight in the following three areas.
Keep an eye on your data center
As the saying goes, “Seeing is believing.” We need to be able to see with our own eyes that everything is truly alright before we can really breath easy. Nothing beats being there, but if you can’t be there, then a video camera presence is the next best thing. With the pan-tilt dome camera, your SecurityProbe can watch up to four separate locations. It can even be programmed to move to a specific location when an event is triggered from any type of sensor. It will also take a series of snapshots and include them with email alerts when triggered by any sensor.
Batten down the hatches
It seems obvious, but the most important places to monitor in secure areas is the entrances and exits. That means, tighten up the doors and windows. Ravica security sensors are contact sensors that are perfect for letting you know when a door or window has been opened. The idea is relatively simple. There are two contact plates. When they are separated, like when the door edge moves away from the frame as it is opened, the sensor switches to an alarm status.
What’s in motion?
A great fail safe, in addition to watching the doors and windows with sensors and cameras, is monitoring for motion. Motion sensors can also sense for unauthorized access, or can simply be the trigger for telling a camera to pay attention to a certain zone. Make sure that the right amount of movement sets off the sensor in a sensitive area and it can mean the difference between knowing during or after a security breach has occurred.
Whether you are guarding Fort Knox or your small corporate data center, putting a SecurityProbe and the appropriate sensors in place can go a long way towards keeping unauthorized personnel away from your sensitive equipment and information.
