HD vs Megapixel – What's the Difference?
Filed under: CCTV Articles, CCTV Camera, Comparisons, Security Camera, Security Camera Packages, Security Camera System
When a customer inquires about a high definition or megapixel security camera you must be able to define the difference and provide the best possible solutions for each application. What is HD? What are megapixels?
Let’s start with the basics. SD (standard definition) consists of 704 pixels with 480 lines of resolution and is the standard resolution that TVs have used until the introduction of HD or high definition. High definition displays consist of at least one million pixels. Note that I said at least one million pixels, meaning that a high definition image could contain more than a million pixels. HD images use an aspect ratio of 16:9.
Next we’ll discuss megapixels. A megapixel security camera is capable of producing an image with at least one million pixels or more. Most consumers would assume that HD and megapixel cameras are the same since they both use an identical number of pixels to produce an image. However, one main variable that sets the two apart would be the size of the image. While HD images use the 16:9 widescreen aspect ratio, megapixel security cameras produce images in a 4:3 aspect ratio. One similarity with both types of cameras is that they use the same video compression, which is H.264.
Ultimately, knowing the differences and similarities of these types of cameras can make or break a sales pitch. Customers want to be well informed and expect you as the salesman to be knowledgeable.

Security cameras at the Dallas-Fort Worth International Airport caught this death defying footage last week as a woman jumped the tollbooth by ramping her car up a concrete barrier.

Authorities confirmed that this wannabe pilot was intoxicated and suspect that alcohol might have caused her to forget about gravity.
How to Avoid Getting Hacked

In 1995, a movie called Hackers debuted showing the life of a group of hackers and what kind of trouble they can cause. Hacking is still an ongoing problem today and as a result has crept into the security market through integrated information systems. In this article I’ll share some tips that can help you keep this cyber intrusion away from your home or business.
Generally, most technologically savvy people get excited about the idea of being able to turn on lights, view security cameras, and control other gadgets at home with a Smart Phone. Unfortunately, there are criminals learning how to break into your systems despite increased security and better technology. So as you log in and review footage on your DVR or control feature of your Smart Home, a cyber thief could be following your every move. The best way to keep these so called cyber criminals from hacking into your system is to use encryption. If you leave any part of your system unencrypted, you’ve already created a huge vulnerability.
Many people in the residential market or in small businesses do not need to go to such extremes as encrypting video feeds. It may be necessary though if you’re trying to protect priceless property or have had issues in the past with people trying to steal certain items.
Some DVRs have a watermark feature to aid in preventing theft. This feature can help a viewer tell the difference between a genuine feed and a fake. I also recommend changing user names and passwords on a regular basis. You don’t want to leave your system with the factory defaults of admin/admin or 12345. Login information like this is what hackers are going to try first. Many customers have asked me to log into their systems and when I ask them what their user name and password is, they often respond saying, “I don’t know who set it up, I just have it saved to auto log in”. This is not a good practice and won’t keep your system secure. Remember if you want to keep your security system safe from hackers, you must, first, keep it safe from a 5 year old.

Security Camera Captures Giant Runaway Saw Blade
First of all, the guy in this video is extremely lucky to be alive. If I were him, I certainly wouldn’t trust that equipment again. On the other side of the camera is the homeowner, who was also very lucky to have had a security camera to capture everything. This begs the question, “Why doesn’t everyone have a security camera installed at their home?” I’m sure we’ve all worried about break-ins while away at work or asleep, but none of us though we’d need a security camera to report property damage due to a 40 inch saw blade crashing through the side of our house. Enjoy the video and remember this, “Anything and everything can and will happen.”
