♦  How to Reduce False Alarms 

Wireless CCTV cameras with built-in motion detection are rapidly replacing “dumb” analogue CCTV cameras, but many of these new cameras cannot tell the difference between a burglar and the sun coming out – leading to many false alarms. Fortunately, something called “Intelligent Image Analysis” has come to the rescue, as this article explains.

More and more people are ditching their old “dumb” CCTV cameras and buying wireless internet CCTV systems because of the wealth of things that they can do with these new “intelligent” cameras – such seeing their property, live, from anywhere in the world, and receiving alerts by email and even SMS text message when movement is detected.

Unfortunately, many of these people are discovering the sad fact that their cameras are not as clever as they thought, and will blindly raise the alarm every time the sun comes out or when a street light comes on. Of course, every single time this happens, the unsuspecting person will get an email or even a text message alert at whatever time of day or night, and this can be a real pain.

For example, if there is a tree branch blowing in the breeze and triggering the camera to raise an alarm every few seconds, this can mount up to literally thousands of alert emails or text messages over the course of a day. Worse still, because the camera so often “cries wolf”, an alert caused by a real intruder may well be ignored and “lost” among the thousands of false alarms.

This is where “Intelligent Image Analysis” comes into play. This is not actually a feature of the camera itself, but a program that sits on a computer server, sometimes on the other side of the world from the property where the camera is located.

This web-based program works rapidly when it receives an alarm message from a camera. It examines each image sent by the camera and interprets it using a complex set of rules. This means that when there is a change of light levels due to the sun coming out from behind a cloud, for example, the system knows that there is no need to panic.

On the other hand, when the movements of an intruder are detected, the system understands the difference and raises the alarm. All of this analysis happens within a fraction of a second, so that the alert messages are still sent without delay.

Intelligent Image Analysis greatly reduces the number of false alarms and in doing so takes wireless CCTV camera systems to the next level.

♦  Top 5 Wireless Security Cameras System

        By Alexander Sutton 

When you are deciding what your top five wireless security cameras that would best work in your home or office, keep in mind the following items when narrowing your decision down. Wireless security cameras come with a variety of options that may or may not work best for your personal needs, but these are some of those options to help you decide which works best.

One of the main points to consider with a wireless surveillance system is range. Is the signal being sent from your cameras close enough for your receiver to pick up the signal? Is the signal strong enough to work through various walls and other obstructions?

Another important point to keep in mind is the type of recording your receiver is using. Is it tape or digital and how much space will you need and what is the most convenient way to access the information later if need be. You might also be interested in wireless security cameras with different recording types, whether the picture is in color or black and white.

Being able to see the details of the image by color might not be the most important thing for your needs, but there are cameras with those options available. Security might come with the requirement of not having the people you are recording see that they are on camera, that’s why there is a wide variety of wireless security cameras that are designed to look like everyday items around the house from screws in a wall, to clocks and lamps.

And if you find yourself concerned with your home or office while away, some cameras have internet options so you can view the content while at a remote location. With these options in mind, your search should be significantly easier for the wireless surveillance system you need.
