One of the most underrated parts of any home security system is CCTV cable. While you can set up a system that relies on wireless CCTV cameras, using CCTV cable adds an extra level of privacy and security.


You can get cable runs of 50 or 100 metres easily, giving you a direct connection between your camera and DVR that no one can intercept. Make sure your security cameras are secure with CCTV cable.

About CCTV Cables

CCTV cable connects wired surveillance equipment, including cameras, to the recording devices and other components of a CCTV system. It is important to buy appropriate cabling, otherwise it may not work effectively to connect the whole surveillance system.

CCTV Cable For A Surveillance System

CCTV cable is one of the most important components in a CCTV or surveillance system. Poor quality cable can become badly damaged, or will simply transmit a low quality image, while good quality cable will enable your system to transmit good quality and over long distances. Wireless systems are typically more expensive than wired system, but if you have to keep buying new and replacement cable, then this may not prove the case over time.

CCTV Uses

CCTV cameras and other surveillance equipment has not only become more affordable, but the range of equipment on offer has increased considerably. This means that cameras are no longer reserved for businesses and the extremely wealthy, and many homeowners and tenants have installed their own CCTV cameras, usually overlooking the exterior of the property and to deter or capture criminals like burglars and vandals.

Components

A CCTV system has many required components to ensure that you can capture the footage you require. The camera itself will transmit to a receiver, which is typically located with a monitor. A recording device is also used, to store the footage, and a range of sensors, switches, and timers can be used to ensure the best results or to automatically capture footage only when required. The quality of all these components is important, but so too is the quality of the CCTV cable that is used to connect them. Poor quality cable could prevent the recording of good quality images, even if you spend a large amount of money on buying the best cameras, monitors, and recording equipment.

Coaxial Cables

Coaxial cables are the more affordable type of cable used in CCTV systems, and a range of impedances means that you can choose low to high quality cables. Where only a very small amount of cable is required, and you do not need high quality recording, 50 Ohm coaxial cable may prove sufficient, but 75 Ohm is the most frequently used. Check the performance by looking at the loss, which represents the amount of high frequency lost per 100 metres, and bearing in mind that the lowest loss figures are the best.

Twisted Pair Cables

Twisted pair cables are most often used in high performance and high resolution systems. Two cables are slowly twisted around one another, and in appropriate systems these CCTV cables can provide much better quality than the equivalent length of coaxial cable. For the average home system, however, these may be considered unnecessary. 100 to 150 Ohms are the most commonly found rating of twisted pair cables for use in CCTV equipment.

Ensuring The Quality Of A CCTV Installation

You should ensure that you buy the best equipment you can afford within your budget, but don’t overlook the importance of CCTV cable. Poor quality cable can completely eradicate the high performance of the cameras and recording equipment that you have purchased, while buying top quality cable for a low quality system means that you will have wasted at least some of your budget.
