Future proof technology
A majority of systems from the late are analogue, in the last few years many of them have been complemented with one or more digital devices like Digital Video Recording units (DVR). This does not the system digital or IP-based, it does however remove one of the most obvious disadvantages, the tapes and the VCR. These system still have the same issue with remote management, image transmission over long distances etc.
If this is your existing system, your system is analogue with limited capabilities of remote management or viewing. You have to change tape and clean the VHS recorder every month. Don´t forget to change the tape every day!!!
By adding an Axis Network DVR you can IP-enable your system with a very small investment. You will get a much better picture quality and you don´t have to change tapes. Cost of maintenance will go down dramatically
Now you don´t need to spend any time changing tapes!
This picture shows the finished system where the existing analogue equipment is kept and complemented with IP-based products from Axis. Note that the new cameras could be either a combination of analogue and IP or just IP by adding a Video server.
This picture is taking it all the way. There are some analogue cameras as there could be requirements that are specific, environmental etc. Also if there is a movable camera, pan, tilt and zoom (PTZ), you have to use a video server to bring it onto the network.
As the need for information and security increases the availability of the CCTV information must be made available to more person in the organisation. Traditionally it was only in the interest of the security manager to see what was going on in the building. Today we have additional services that have specific interest, the IS department needs to know who is accessing their closed areas. Having the possibility to see brings comfort to people.
Taking it all further. As the amount of information constantly increased there must be systems doing most of the generic work and only notifying the operators when there something out of the normal pattern that takes place. One such application could be image detection where the camera initiates action depending on the movement in the picture, it could be a conveyor belt that stops or a car driving up the drive way.
Multifunctional cameras are already deployed, daytime used for recording transactions or counting people that passes a certain point in a shopping mall. Night time they become surveillance cameras as part of the CCTV system.
A possible application could be object tracking, to know where and object or a person is within a given area, cameras that communicate, exchanging information on what they have seen, putting two and two together in order to notify the operator about a possible situation.
Networked Video advantages
Direct access to live images from every network attached PC with a standard Web Browser – Analog CCTV needs dedicated video monitors and is limited to small local areas Remote-Monitoring over Intra-/Internet and telephone lines all over the world – Analog CCTV requires additional hard- and software. Broadcast, multiple access to live images at the same time – Analog CCTV is a point to point connection, multiple access needs expensive special equipment like Video-Matrix-Switcher
Digital images gives Direct access to recorded relevant images. Seach functions etc
Image recording without a need for special recording devices – Analog CCTV reqires special devices like Time-Lapse VCRs and Multiplexers
A Digital solution open the possibility for integration with other systems such as Access Control systems, Building Management Systems, etc
Digital is the future, compare with telephones... How many of you are using an analog telephone?
Cost reduction by using of existing TCP/IP networks – Analog CCTV requires a dedicated coaxial cable network
100% digital
Less maintenance for not using VCRs with tape.
