Understanding Wide Dynamic Range

When it comes to surveillance cameras, visibility is key.  Some of the obstacles surrounding a camera’s capability to retain clear images such as lighting, camera installation, and type of camera are somewhat within our control, others are not.  Uncontrollable issues of extreme brightness, like light produced from headlights and the sun, or extreme darkness are not necessarily easily overcome.  However, as with anything, technological progression helps change these harrowing limitations.  As industry professionals our team at Perfect Connections, Inc. has been providing security system solutions, including surveillance, to organizations throughout northern and central New Jersey for the past 23 years.  We’ve seen the impact changing technology has on the equipment we install and how it can be beneficial to our customers.

Surveillance systems are in the midst of a transition from using conventional analog equipment to IP (Internet Protocol).  Why? For one, image quality.  The tricky thing with IP cameras is not all are created equal.  There isn’t necessarily a defined industry standard that is accepted by all integrators and camera manufacturers when it comes to “best” image quality.  For example some might argue that the higher the megapixel count the better, but it doesn’t necessarily guarantee a better image.  At least with HD (high definition) cameras there are standards manufacturers must comply with in order to be considered HD.

Aside from pixel count, an IP camera’s display threshold in extreme conditions is critical, but limited.  This limit, specifically when referring to extreme brightness or darkness, is typically known as “dynamic range.”  Wide dynamic range (WDR), “allows cameras to capture much more detail in scenes where there are varying levels of light, much like the way the human eye ‘processes’ these types of scenes.”  You know the feeling of widening your eyes in the dark to try to see clearer because you’re eyes haven’t quite adjusted yet?  It’s sort of the same idea with WDR cameras and how they adapt in both light and dark conditions.  However, their adjustments aren’t a physical strain and transitions are typically quicker than ours.

WDR footageThe images above show the difference between a parking garage being monitored by a camera with no WDR or WDR turned off on the left, and on the right the same area monitored by a camera with WDR enabled.  The difference is clear as day.  Why do they differ so much?  The camera with the WDR enabled has two internal Charge-Coupled Devices (CCD).  The two devices, or sensors, scan an image at different speeds, one low and one high, the image processor then combines the separate images producing a clearer, more balanced picture with better contrast and lighting.  This process happens quickly enough to produce a stream of clear recorded footage.  There are many different manufacturers that produce these WDR cameras in the market today, and not all of them use the same type of sensor and image processing combinations.  The best way to ensure you are getting the best camera for your specific application is to hire a licensed security systems integrator who is educated in which camera specifications will work best in variant conditions.

WDR technology, like anything else, is not perfect.  Depending on the camera manufacturer, you could end up with a camera that takes up to 15 seconds to adjust with varying light levels.  That doesn’t sound like that long, but it could mean the difference between catching a perpetrator and them getting away.  Another issue you might run into are cameras that don’t have the ability to turn WDR settings on and off automatically.  Without the automation the transition becomes the responsibility of someone on site, which can be time consuming and ineffective in a time sensitive situation.  This is why it is vital to consult a professional security systems integrator who is educated in the differences between product specifications and their appropriate applications.

The clarity of recorded video footage is crucial to the security of any organization.  As a business owner you don’t want to be left wondering why your recordings are grainy, washed out, or so dark they become unusable.  No one can control the external factors that affect an organization, but you can be prepared for them by taking the proper precautions.  Licensed system integrators are there to help.  Our team at Perfect Connections, Inc. has been providing comprehensive security system solutions to businesses throughout northern and central New Jersey since 1992.  We recognize the importance of utilizing quality security products that not only perform well but perform to their intended specifications.

Upgrading An Old Security System

Old Tech-Steve JurvetsonMaybe you’ve had a home security system installed years ago or perhaps you recently moved into a new home with an existing alarm system.  Whatever the case, how can you tell if your home security system is still valid?  There are some tell-tale signs that you may be dealing with an antiquated system.  However, if you have a security system and are concerned it’s not as relevant as it once was the first thing you should do is contact your security system provider for an assessment.  As a security systems expert, our professionals at Perfect Connections, Inc. understand the importance of maintaining a functional security system and keeping up with advancing technologies.  Our team of professionals have been providing comprehensive and customized home security systems throughout northern and central New Jersey for the past 23 years.  We can help assess the validity of your alarm system and offer solutions specific to your security needs.

Maintaining an effective alarm system isn’t just about running annual tests, it’s making sure it progresses as you, your home, and technology press forward.  It’s not like buying the newest IPhone just to keep up with trends, it’s making sure the technology you’ve invested in is providing the best protection.  If you’ve had a security system for a while and can’t remember the last time the software was updated, or if updating isn’t even an option it might be time for an upgrade.  Outdated software may leave you susceptible to hacking and viruses, plus you may not be getting the most out of your system.  You don’t want to pay for a system that’s subpar right?

Another sign it might be time for an assessment or system upgrade is the dependence on a singular keypad for control.  In today’s fast-paced world we often have the need for convenience.  Is it convenient to have to drive home from work because you forgot to arm your security system?  Is it convenient to have to make it to the security keypad to punch in your pin while your arms are chalk-full of groceries?  No, so why not look into interactive services or home automation?  With home automation you no longer have to worry about forgetting to arm or disarm your system because you can do it from your mobile device from virtually anywhere.  You could access your surveillance system through an app on your mobile device, allowing you to view what is going on real-time at home.  Other advantages to an interactive system is the ability to adjust your thermostat and lighting from afar.  As Alarm.com puts it, “Using a smartphone to manage an interactive home security system is like having a remote control for the system right in your pocket.”  This added technology will save you time, money, and lots of headaches.

How was your security system originally installed?  Was it hardwired?  While there is nothing necessarily wrong with a hardwired system it’s important to consider current technology benefits and how your system compares.  Just as our phones have become wireless many industry professionals are installing wireless security systems with cellular capabilities.  Why?  For one there’s no need to tear open walls, which is costly and laborious.  Technology has advanced to the point where wireless capabilities have become more effective and ubiquitous making them more viable, dependable, and available.  When comparing wireless to hardwired systems a noticeable difference, aside from the wires, is the continuity of service.  With a wireless system you don’t have to worry about burglars cutting wires to disable your system because there are none.

Lastly, a common sign of an antiquated security system can be low-res (low-resolution) cameras.  While cameras alone can sometimes deter an intruder from attempting a break-in, what good is a surveillance system that offers fuzzy picture quality if a break-in does occur?  The purpose of a camera is being able to record quality footage to positively identify intruders and sometimes their vehicles if need be.  Clear footage can be a helpful tool for law enforcement and in court.  Effective cameras can also be used to monitor the arrival of packages, expected and unexpected visitors, interiors and exteriors, remote properties (i.e. barns, sheds etc.), and distant areas of your property.  Fortunately there is a vast array of high-resolution cameras available today.  Your security system company will be able to provide the best solutions for your specific needs.

Whether you’re unsure your current security system is functioning optimally or if you’re looking into home security for the first time, contact a specialist.  They will be able to assess your current security situation and provide customized solutions.  Our team of experts at Perfect Connections, Inc. has been providing custom home security systems throughout northern and central New Jersey since 1992.  We can help you update an outdated system and offer comprehensive systems for new installations.
