When building your surveillance system one of the first questions you will need to ask yourself is: what type of system technology do I want to use? There are six types of surveillance systems, each with advantages and disadvantages. You will need to consider your budget and surveillance needs when deciding between the following technologies:
IP- Network IP surveillance systems are at the cutting edge of video surveillance technology. They are quickly becoming the most popular choice for surveillance needs because they offer high resolution video and easy installation. These systems offer the highest resolution on the market, sometimes exceeding 1080p. Cameras connect to the NVR via CAT5 cable and connect over an internet connection. These systems use fewer cables than some other systems and that makes installation easy.
CVI- This technology rivals that of Network IP and HD-SDI systems without costing nearly as much. HD-CVI systems typically capture and display footage in 720p or 1080p resolutions. The cameras and DVR connect via Coaxial (RG59) cable. Both copper core coax cable and copper clad aluminum coax cables perform well with these systems. HD-CVI cameras MUST be used with an HD-CVI DVR. If you are looking for a surveillance system that provides HD footage at an affordable cost then CVI may be the best option for you.
TVI- The TVI technology is very similar to CVI. It provides HD resolution images in 720p or 1080p and transmits over Coaxial cable. TVI and CVI are NOT compatible with one another; users need to pick one technology over the other. CVI has been more widely adopted by the CCTV industry but TVI works just as well.
SDI- High Definition Serial Digital Interface also operates over standard Coaxial cable. These systems provide High Definition surveillance in 720p or 1080p resolutions with footage being recorded on an HD-SDI DVR.
AHD- Analog HD is a higher definition version of the typical analog systems. AHD is one of the competing technologies available now that can transmit up to 1080p video using existing coaxial cabling. This technology is a good option for users looking to transition their system from analog to high definition.
Analog- These systems use an analog signal to broadcast the video signal directly back to the DVR using Coax cable. Analog has the lowest resolution images on the market, typically between 600TVL-1000TVL.This is not a high definition system but it is the most affordable option on the market. For customers on a tight budget, who do not need to capture a great deal of detail in their security footage, Analog may be the best option.However, it is important to note that analog system are quickly being phased out and replaced with higher definition systems.
Worldeyecam also offers Universal ACT Cameras that can switch between analog, AHD, CVI and TVI technologies. We also have Universal DVRs that can record footage from analog, CVI and IP cameras. These options are great for customers that want to try a few different technologies before committing. They are also great for customers that are looking to gradually transition from an analog system to a high definition system.
