In the CCTV world, there are two types of systems; digital and analogue. In the past, analogue CCTV systems were the only option. The system simply recorded activity for future access. However as this system does not broadcast actual live information, it is not practical for monitoring stores or businesses from a remote location. The picture quality is low and sometimes unusable for legal purposes. Analogue systems rely on human intervention, as you will have to change tapes regularly.
Although analogue served a purpose, digital CCTV is revolutionising the way CCTV is used. We look at ten reasons why digital CCTV systems are better for your business.
- Digital CCTV stores as many recordings, from as many cameras as you like. You will only be limited by the size of the data storage on your computer or server.
- The quality of your images you record using digital CCTV will be better and will also be cheaper to copy to CDs/DVDs to pass around if needed.
- Digital CCTV recorders record up to 100 images per second, and can record simultaneously from each camera.
- With digital CCTV, it’s easy to sort through recorded data for a particular event and you can connect to the digital CCTV system over the internet to check on recordings.
- Digital CCTV is unique in that it will only record images when movement is detected. This ultimately means that you will only have CCTV footage of activity, instead of hours of empty images.
- Analogue CCTV means you will need to change the tape every day, and have the space to store the videos.
- When you copy or record over the tapes, the picture quality degrades, so you’ll need to replace them, using hundreds of tapes.
- Analogue systems record from each camera in turn.
- If you use analogue CCTV, you will need to manually search through recordings to find the incident you want, and as it records everything, that could be hours of tape!
- Analogue cameras require complicated cabling that can be quite expensive and also challenging to install.
