GeoVision & AVerMedia Pros & Cons
Posted by gfutrell in AVerMedia, Comparisons, GeoVision on December 21, 2009
Greg, one of our technicians, compiled this quick-reference Pros & Cons guide for AVerMedia & GeoVision. These are opinions, based around several years of experience with both manufacturers, and are open for discussion. It is also not a GeoVision vs. AVerMedia war, only observations of both systems.
GeoVision
Pros:
- Major remote capabilities
- Enhanced Pan/Tilt/Zoom (PTZ) Control
- More flexible masking features & individual camera settings
- More stable software
- Focus on surveillance products
- Complex user interface, with many options & settings that are relatively easy to find/use for an experienced user
- Software is easy to install
- Playback is detailed
Cons:
- Requires a powerful computer for larger CCTV systems
- User Interface can be too complex for newer users
- Software is not easily removed for re-installs, etc
- Requires additional license purchases to integrate non-GeoVision equipment
- There are currently no 64-bit drivers for their equipment
AVerMedia
Pros:
- Easy to use software
- Easy to install IP cameras
- Newer users should have no problem finding & figuring out settings
- Other hardware is easy to install & integrate (does not require additional licenses)
- Playback is simple & easy to figure out
Cons:
- Requires a powerful computer for larger surveillance systems
- There are some software issues with the drivers that can be irritating
- Like GeoVision, there are no 64-bit drivers yet
We would love to know your thoughts on the Pros & Cons between these two widely-used security solutions providers. There are many other observations that could likely be mentioned, but if you want to read more about GeoVision & AVerMedia I suggest checking out our other articles:
BNC, RCA, VGA & RJ45 Connectors Explained – CCTV Video
Posted by joeltjen in CCTV Training Videos, Cables, Comparisons on October 20, 2009
I saw Jon’s post on Analog vs. Digital resolution and thought that one of our training videos that explains the different video connections used in CCTV would be good supplementary material.
If anyone has ever wondered what the differences are between BNC, RCA, VGA & RJ45 connectors, this video should help to clarify by explaining how they are used to connect security cameras to monitoring and recording devices.
Analog vs. Digital Resolution – TV Lines (TVL) vs. Pixels
Posted by jhough in CCTV Articles, Comparisons on October 19, 2009
One of the most confusing and difficult topics in the CCTV world is resolution. Most of us have digital cameras or video camcorders and have heard the term megapixel used as the most common comparison in resolution between various makes and models. We are also aware that a larger number means better picture quality, but many people do not know why. In the CCTV security camera world, though, most cameras are still analog and their resolution is measured differently from what we are used to.

When measuring analog resolution, a TV line does not have a defined number of individual pixels. Instead, the term “TV lines” refers to the number of discernable horizontal or vertical lines on the screen. Analog security cameras are measured in Analog TV Lines, and most of them have between 420 and 580. The higher number of TV Lines, the more information captured. These types of cameras connect to a security DVR or CCTV VCR via coaxial video cable.
A pixel is the smallest element of a digital image. We have all zoomed too far into a picture from a website and seen the image go from clear to a bunch of colored squares – each one of those squares is an individual pixel. A megapixel (MP) is 1 million pixels, and is a specific measurement for digital resolution that encompasses the area of the output video.
Example: If a camera outputs a signal that is 1280×1024 pixels, it is shooting at a megapixel resolution of 1280 x 1024 = 1,310,720 pixels = 1.3 Megapixels (MP).
The most common type of digital security cameras are IP Cameras. These, like your digital camera at home, use strictly digital resolution. They utilize a network connection to either act as a standalone device or connect to a network-based DVR (Digital Video Recorder) or NVR (Network Video Recorder). IP Cameras have fixed resolutions and are now approaching, and in several cases exceeding, 1 megapixel in resolution, on average. Many of these cameras also support POE (Power Over Ethernet), which allows them to be powered by the Ethernet cable used for network connectivity, and PTZ (Pan Tilt Zoom), allowing for remote control of the pan, tilt and zoom features, if applicable.
I hope this helped everyone distinguish the differences between Analog (TV Line) and Digital (Pixel) Resolution. We would love to know what you think of our articles, and if you have any further questions, don’t hesitate to leave a comment!
PC Based DVRs vs. Standalone DVRs
Posted by gfutrell in Comparisons, Security Camera System, Security DVR on October 14, 2009
I get calls on a daily basis asking which I prefer, PC based or Standalone DVRs. In most cases I would have to say PC based systems. Don’t get me wrong, the standalone units are great for small budgets, but when you need to retrieve the data from one or expand your system…
Standalone DVR Overview
Several people want to use the smaller, less expensive DVR… and for good reasons. One would be cost; they range in price from a couple hundred to a few thousand dollars. Also, they have all the operating system software written directly into the motherboard, making them more secure from outside threats. Some have a fairly simple menu and even use a remote control or mouse for on-screen navigation, too.
Overall, though, these smaller, less expensive units all have a few failing points. Since the standalone DVRs typically use a Linux based operating system, they are often difficult to link to a PC for backups, etc. Several have built in CD/DVD burners that allow you to backup your security camera footage directly, but you still need a PC to play the files. This is where the fun begins; you will likely need special software or video codecs to view the file on your PC! Sometimes the DVR will come with the needed software, but if you are reading this post because yours did not, I would suggest downloading the “K-Lite Codec Pack – FULL.” Once installed, that should allow you to play almost any video you will ever come across. If that does not work, I would say contact the manufacturer or check out their website to see if they can offer any insight.
The final “con” associated with Standalone DVRs is that they are basically trash if the unit ever stops working. Most of the time you get your money’s worth, though.
PC-Based DVR Overview
I would much rather look to the long term of the device I purchase. With a PC-based DVR, you have a lot more versatility and power, but also a larger price tag. You have all of the options that Windows gives you, and unfortunately the drawbacks too. One major “pro” is that you have the ability to upgrade the DVR to a more powerful system and add additional CCTV cameras later, if wanted. The added ability to choose a surveillance company’s DVR card and the options that they provide increases the desirability, in my opinion.
These systems allow for more reliable control over your security system and the ability to extract the DVR data, when needed, is easier. Larger companies, such as banks, schools and casinos, rely on the options given by these extremely customizable PC-based DVRs. Being Windows systems, the CD/DVDs that you backup to can be played on any similar windows system (may still require codec updates).
In summary, PC-Based DVRs can make surveillance at home, business or school easier to deal with, but they still have a few drawbacks, such as power cost, size and having to use Windows Vista in most cases. Overall, I prefer my video surveillance be done with a PC.
