Leading the Megapixel CCTV Technology

 

The CCTV market is taking a evolutionary step forward with the inception of Megapixel ip cameras, perceived by many as the future of the CCTV market

 

Multi-megapixel (MP) IP cameras are now available that offer a huge jump in image quality compared to conventional surveillance cameras.

 

Example of Megapixel Surveillance

 

One of the most compelling advantages of Megapixel CCTV surveillancesystems is their ability to capture not only situation awareness the big picture of what is going on but also fine details that can be used for license plate reading and identifying people. The combination of situational awareness and detail allows security operators to react faster and reduce investigation time, all with a higher probability of prosecution and conviction.

 

The images below illustrate how HD  Megapixel CCTV surveillance systems can capture full situation awareness as well as fine detail.

 

    A standard camera would only be able to view this image and would then need to be zoomed to view the detail via a PTZ and thus loosing the rest of the picture that is out of view.

    With Megapixel cameras this detail can be zoomed into whilst the still recording the whole picture.

Electronic Pan Tilt Zoom (ePTZ)

Every Nione Security Megapixel includes digital pan/tilt/zoom ePTZ. ePTZ was developed to address problems with traditional mechanical pan/tilt/zoom devices. Mechanical devices let users redirect the camera but only record what you are zoomed in on. This can be a problem when there is more than one subject in the scene or if nobody is controlling the camera.

    The Nione Security’s Electronic Pan/Tilt/Zoom ePTZ lets you virtually move around a large image using a smaller viewing window. Since it is virtual, you can still record the entire scene in Multi-Megapixel resolution even though you may be digitally “zoomed in”. This means you never miss a thing.

    ePTZ also saves bandwidth. In many cases you don’t need to view a Multi-Megapixel image when you are accessing video over a WAN or the internet. Nione Security’s ePTZ enables you to view a much smaller image that shows the entire field of view in a smaller window. If you see something that interests you, simply zoom digitally and the Nione Security’s Multi-Megapixel resolution kicks in. As you zoom in, ePTZ introduces more detail so you don’t suffer the distortion typical with other products.

8mm lens or 3.6mm lens for a surveillance camera?

I am adding a new camera to my system, I am interested in these two cameras: http://cgi.ebay.com/SONY-520-TV-LINE-60-IR-150-FT-NIGHT-VISION-CCTV-CAMERA_W0QQitemZ270467495971QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item3ef91e7823
and http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=270457880428&ssPageName=STRK:MEWAX:IT

As you can see in the specs, one is 3.6mm lens and one is 8mm lens. Everything else looks the same but the 8mm lens one come with a power supply and they both cost the same price. So which one is better? the 3.6 mm or 8mm, I want the one that will have the best resolution and picture.

Check out the specifications about the sensor size and buy the one that has larger sensor (physical dimensions).
