Moving to an NVR doesn’t mean you have to replace your existing cameras. You won’t get all the features or the higher picture quality if you’re not using digital cameras, but you can still use many NVR features including Internet viewing. If you’re looking at a new DVR, you might want to look ahead to an NVR, especially if you’re considering remote viewing of your camera system and moving to digital.
Network video servers (NVS) are a lot like NVRs. The main difference is the NVS connects directly to your network and has no storage device. This is a hardware device and a software product. IP cameras can connect to your network through any IP connection point you have. This gives you the ability to use your existing server and network to build your CCTV system. The best part is you don’t have to be a member of the geek squad to install it or make it work. This is all thanks to new technology and user interfaces.
The introduction of NVR and NVS technology has given us the final piece for true remote viewing—the ability to log into your camera system via any Internet connection at any time.
With remote viewing, managing the connection is only half the problem. You need a connection that will handle the demands of video streaming across the Internet. Unless you have the ability to install a T1 connection, you won’t be able to handle video streaming to more than one source at a time. In other words, only one person at a time could view the camera system. The way around this is to use a data bank, a service that allows you to have several people viewing data at the same time.
You also have the ability to view multiple sites simultaneously. This is accomplished by re-broadcasting your video through multiple T1 lines which, in turn, gives you faster video connections.
There is a bonus to using a data bank. By connecting to one, you have the ability to use offsite storage, which acts as a backup to your system and allows for storage of critical files for an unlimited time. You can also have the data bank alert you if you have video loss due to a camera outage or system problems. You’ll know within minutes if you have a problem and can contact the site or service provider for corrections. You can even review files and look at the system at the same time. This eliminates gaps in service and security.
We live in an ever-changing world, and we’ll certainly see more changes in the CCTV market. If your system was installed more than five years ago, it’s time to look at some of the new features and abilities. Consulting with a qualified distributor can be an eye-opening experience and allow you to see what you’re missing.
