As the cost of bandwidth goes down, the appeal of IP-based camera systems goes up for companies that require a flexible, cost-effective surveillance solution with enhanced functionalities such as remote accessibility and better scalability.
Within CCTV (closed-circuit television) surveillance images are captured and recorded on a digital video recorder (DVR), with the images being relayed through analogue cables going from the cameras to the DVR in the surveillance room. IP-based surveillance cameras store their data on more common PC storage devices by way of a wireless network or wired set-up (CAT-5 network cables), thus helping businesses save on installation costs as existing network infrastructure can be repurposed for surveillance.
Unlike an analogue system, IP security cameras can be installed at any location, no matter the distance from the surveillance room housing the storage equipment and can also be easily moved from one location to the next, without any cabling needing to be replaced.
- IP security cameras can be installed at any location.
- Any amount of recordings per camera can take place simultaneously.
- There are advantages and challenges in IP surveillance.
