Our Guide to Installing the Correct CCTV SystemsInstalling CCTV systems for use at home or work can provide a number of benefits and we have outlined the most important things to consider before installing a CCTV system. At CCTVdirect we do all we can to ensure you receive the best possible service and only sell tried and tested equipment. Selecting the right CCTV equipment is essential if you are to achieve your aims. The first thing you must do before purchasing any cctv set up is to identify why you need the system and what benefits it will bring. Then think about the total number of cameras you may need, a wide angle camera will cover a large area but offer you low definition. Therefore its sometimes better to install a couple of cameras that offer a close range focus than one covering a wide area. If you need to install CCTV cameras low down it may be an advantage to use a Vandal dome camera, these cctv dome cameras can be wall mounted and are vandal proof (also see The Mosquito ultrasonic teenage deterrent). Good quality CCTV cameras change to monochrome in low light, if they are True day/night cameras they will perform much better as the camera physically changes the filter on the lens. A further thing to consider is do you require IR illumination, most external cctv cameras now have IR LED’s. IR cameras are often rated by the distance the IR will cover, this should only be used as a guide as some retailers often don’t understand this value and often enhance the actual IR range. It is also worth noting that Infra red does not work very well on grass or similar subjects. Infra Red CCTV cameras are called a number of things, such as bullet cameras, IR cameras. The CCTV DVR you select will depend on the total maximum number of cameras you may require, if you need a maximum of 4 cctv cameras choose a 4 way DVR recorder, if you think you may need 5 cameras select the bigger 8 way DVR. If you are unsure where to start, take a look at our CCTV kits, these kits offer everything you will possibly need in a discounted package. Our CCTV kits come in a number of different combinations either offering external IR cameras or internal dome cameras. We can also alter the combination of cctv cameras to suit your requirements. If you require internal dome cameras rather than external IR cameras then that’s not a problem. At CCTVdirect we ensure you receive everything you could possibly need our discounted cctv kits, we even include the screws. When selecting a monitor for your system you can either use your existing TV (you will need a BNC to scart convertor) or select a CCTV monitor. A CCTV monitor has the benefits of a BNC connection and usually offers a BNC output to allow you to connect multiple screens from the same feed. |
