When Axis invented and launched the world’s first network camera in 1996, the company initiated the market’s ongoing shift from analog to digital video surveillance. The benefits of network video compared to analog CCTV technology are numerous: it can save you money, help you work more efficiently, and give you better quality video. It also allows you to integrate your video surveillance with other systems for new, endless business possibilities.
But what if you’ve already invested in analog CCTV cameras and recording devices? Axis offers a wide portfolio of equipment such as video encoders, chassis, and adaptors to easily and instantly provide you with the benefits of network video - without sacrificing your analog investment. Regardless of the size of your system, you get a platform to expand and update your infrastructure with network cameras, software and recording devices. With Axis, you can migrate from analog to IP at a pace that you are comfortable with.
The simple steps
A video surveillance system, regardless if it is analog or digital, consists of three main parts: the cameras, the infrastructure (cabling), and the equipment to monitor and record the video. The products you choose to support your transition from analog to IP depend on what goals you have with your migration.
1. Migrate to IP but keep analog cameras and cables
This is a typical first step: your DVRs need to be replaced and you decide to go for an IP recording solution. This could be a Network Video Recorder (NVR), or a PC-based system with video management software. In this case, you would connect the coaxial cables from your existing analog cameras to an Axis video encoder, which in turn is connected to any IP network. Axis’ encoders support both single and multiple channels of analog cameras. For a mid-size or larger installation, Axis’ video encoder chassis offers a high-density solution which also can be re-used when you are ready for the next step in your migration to IP.
2. Replace analog cameras with network cameras, but keep the coax.
In this step, you have decided to add new network cameras and replace some or all analog cameras. Analog cables are usually long and can be difficult, time-consuming or expensive to replace. In this case, you can still make use of legacy cabling for both power and data by using Axis’ Ethernet over coax adaptors. Use one adaptor to connect your new IP camera to the analog coaxial cable, and the second adaptor to connect it to the network.
If you in your first step invested in Axis’ video encoder chassis, you can benefit from it now in the second step. Axis PoE+ over coax blades fit any Axis’ video encoder chassis. Any combination of encoder blades and PoE+ over coax blades can be used simultaneously so you can migrate to IP cameras at any pace you want.
3. Leverage on the flexibility and expandability of IP network
Now you have a full IP network and you can add further network cameras with a PoE powered switch, or add other IP devices such as access control units, network speakers etc.
