As anybody who values the safety of their premises will know, it is necessary to invest in the highest quality security equipment for the job. Alongside obvious items such as burglar alarms and sturdy locks, it is a good idea to look into installing an HD CCTV system.
CCTV systems come in a wide range of different varieties, but an HD system will be your best bet: if you capture a suspicious individual or activity on camera, then HD footage will ensure maximum clarity. If you settle for lower-quality cameras, then you may well miss out on vital details should a crime occur on our property.
CCTV systems have long been fixtures of professional property. Today, the increasing availability and affordability of CCTV systems means that more and more private citizens are installing them: a simple CCTV camera mounted outside the house will be a perfect way to deter burglars, vandals and other intruders from your property. If you have never seen HD CCTV footage before, then you will be surprised at how much clearer it is than the old-fashioned CCTV recordings that you may be familiar with.
It is never a good idea to leave things until they are too late. You can readily imagine the frustration felt by somebody who considers investing in security systems, but never gets around to it – until their home is robbed! That person will most certainly be left wishing that they had installed a CCTV system, make no mistake.
Make no mistake: an HD CCTV system is a vital part of a household security set-up if you hope to take the extra step in keeping your property safe. If you have not already considered having one installed, then now would be the perfect time to look into the matter.

AHD CCTV is an analogue, extremely high-definition, closed-circuit TV surveillance system that incorporates a coax cable in order to broadcast a sharp HD video from certain security cameras to DVRs. AHD works symbiotically with 720p and 1080p HD video resolutions. Importantly, you can use varying types of AHD CCTV cameras, dependent on what you need.
What type of cable do AHD cameras use?
AHD CCTV cameras are joined to DVRs as they use the same coaxial cable as older, more traditional CCTV systems – these are typically RG59 or RG6 coax cables. One of the main advantages of AHD systems over simpler HD-SDI, is that RG59 coax cables can be installed to run along longer lengths without degrading the quality of the image seen on the camera. From research, installers can use a RG69 coax cable up to an impressive distance of 800 feet for all AHD cameras. Alternatively, AHD cameras can also use UTP cable, which include video baluns; this means cable can be ran up to 320 metres (960 feet) with a CAT5 cable.
Will AHD replace analogue CCTV cameras?
Only time will tell if AHD will become more widely used then CCTV systems. CCTV technology is currently very stable and installing systems is very, very affordable. Interestingly, some people in the CCTV industry thought that analogue CCTV systems would have fallen out of favour years ago.

In 2007 megapixel resolution cameras were catching attention. Despite the attention, a lot of people found that IP cameras were difficult to install and maintain; the pricing never came down either, so people lost interest, as the technology never justified the price-tag.
HD-SDI entered surveillance industry around 2010, despite being used to make films and HDTV for eons. Although people really like using HD-SDI cameras, the general acceptance of them, as a concept, has been severely limited. Many say that HD-SDI cameras are fundamentally flawed because you cannot run a coax cable long distances; plus, there is no assistance for video baluns. Despite all these drawbacks, the picture quality of HD-SDI is not matched by anything else on the market.
