Advancement in technology and infrastructures happen quickly and continuously, thus, it is not surprising for users to consider occasional upgrading to their existing surveillance systems. However, there is no need to start the system all over again from scratch, perhaps one may already own a great system which they are very used to, it is just that over the years, loopholes are observed and the environment where the system is located had changed. Hence, instead of a reinstallation, some people will explore the option of adding new members to the current unit.

 

One of the more common addition or change that is being made will be to turn the old VCR (Video Cassette Recorder) into DVR (Digital Video Recorder). This new kid helps in digitising analog video images into digital ones, so as to get a better resolution for all recoded footages, permits the most suitable frames per second (FPS) for better visual event coherence, and store sufficient required amount of data etc.

 

Furthermore, an even newer alternative comes with NVR (Network Video Recorder), which records footages digitally right away. Such change will also mean that owners will have to replace all their analog cameras into compatible IP (Interpol) cameras. Nevertheless, recent manufacturers also embed NVR function into DVR, so users have the freedom to choose between the two, for different circumstance and context.

 

It is rare for one surveillance system to come with just one camera, thus if the existing cameras are working fine, there is no need to change all of them, even though they may not be the latest or most advance. Often, a good recording device and brand new cables well-suited to these old cameras, will help to overcome any susceptibility. However, if changing the cameras is within your option, one of the most popular choices will be to upgrade them into High Definition (HD).

 

HD security cameras are becoming more affordable over the years. What stands out from the traditional analog cameras is that, HD cameras provide better face recognition. HD cameras, unlike analog, no longer blurred images upon zooming in, rather, they enable better zoom in and to see details of features the target have.

 

However, do take note that users have to ensure cables embedding the HD cameras are adaptable to the control panels and monitors. Absent of compatibility will result in bad or even worse imaging than the initial set up.

 

It will be a chore to list down each and every of the existing structure, one can consider upgrading. On top of cameras, wiring, and software, perhaps one should also consider investing on an appropriate storage device. A good and systematic storage device will allow easy retrieval of footages when in need.

 

Regardless of which, one should never leave the option of enquiring an expert out. Do make consultation when in need.
