If you’re thinking about having a CCTV system installed, there are a few things that you may need to consider when making your decision. The type of system that is best for you will depend a lot on your individual needs, premises and budget, but, with all of the technical jargon that is often used, it can be difficult to make an informed choice. So, here’s what you need to know:
Cameras & Resolutions
CCTV systems can record in a certain amount of FPS (frames per second). This means that your footage can be shown to ‘flow’ in different ways. For example, when recording a low FPS, the footage will not show in ‘real time’ (the amount of FPS that the eye can see), meaning that it will jump from frame to frame, lowering the quality of the footage.
Recording can be set up in real time on certain systems, which is approximately 25fps, meaning that the ‘flow’ of the footage will appear the same speed as it would have done in real life
Similarly, CCTV cameras will record in different resolutions, for example, you can have SD (Standard Definition) or HD (High Definition), which relates to the quality of the image.
Images are made up of ‘pixels’ (essentially small coloured squares that group together to create the image), therefore, the more pixels that a camera can capture, the better quality the images will be.
These pixels are very small, so they are measured in ‘Megapixels’ (one megapixel is 1000000 pixels). In a standard definition CCTV camera there are 0.4 Megapixels, where as an HD camera captures over 2.1 Megapixels. This is the reason that the difference in image quality is so substantial.
To store and stream footage your cameras will need to be connected to a DVR (Digital Video Recorder) or an NVR (Network Video Recorder), which will be the device through which you control your system. These come with a number of different recording formats, capacities and connectivities.
Your recordings can be stored either on an internal or external hard drive, on a USB storage device, or on a disk.
As well as this, your CCTV system can be either wireless (IP) or wired. Again, both will function in more or less the same way, but one may be more convenient for your requierements or the nature of your property.
Another good function of modern-day systems is remote viewing; this requires a broadband connection within the premises, but will enable you to access your closed circuit television system from any other place in the world (as long as you have internet access). Using a smart phone, tablet or computer you are able to log-in to your CCTV system, using your secure username and password, and remotely view your recording. Some appliances will even enable you to stream live footage directly to your computer, smart phone or tablet, which is ideal for people who have their own business, or for people who have more than one property (a holiday home for example).
Though some of these systems may sound expensive and complicated, now is a better time than ever to ask about upgrading your CCTV system. With the equipment prices at a record low, surveys 100% free of charge, and engineers on hand to help you 24/7, you’ve nothing to fear about taking the leap.
