Technology changes. Daily. And that does not exclude your security camera surveillance system. The majority of surveillance systems currently in place are analog, but within the last couple of years, digital or IP camera surveillance systems have become much more popular as the technology and image quality are much better. The analog system usually use coaxial cabling (or Cat5 with video baluns), which results in an image quality such as this:
Facial recognition, license plate capture, and other important features to identify suspects are often not obtainable with analog cameras.
Maryland Security Professionals can upgrade an analog security camera surveillance system using the current cabling, whether it be coaxial or Cat5/6, to obtain high definition, 1080p video recordings. There are four different analog high definition formats; HD-SDI, AHD, HD-CVI and HD-TVI and corresponding equipment for each format. For the most part, there is NO cross compatibility – you cannot use an AHD recording device (DVR) with a HD-TVI camera. However, all of the analog HD systems can record standard definition analog cameras along with HD analog cameras. There are clear benefits to using some of these formats over the other, which are referenced here: Comparing HD Analog Formats
A cost effective approach is to use HD-TVI for a few important reasons:
- Cost: the cost of TVI is comparable to that of your typical analog standard definition cameras
- Transmission Distance: TVI can transmit HD video at longer distances than any other format – there is no need for additional equipment (i.e. video signal extenders) when installing cameras really far away from the recording device.
- Variety: there are many companies manufacturing TVI cameras now, and all TVI cameras are compatible will all TVI recording devices and vice versa.
