CCTVs have proven to be a great help in crime prevention and detection and are being successfully used in many circumstances and places. Conversely, Closed Circuit Televisions being in many public places is a threatening fact to people's privacy. Just imagine that everywhere you go, there's a big chance that a CCTV system has been installed there. For many this feels like they are being watched at almost all times; that's not a pleasant thought. However, the thought that Closed Circuit Televisions can bring more safety can act as a comfort that undoubtedly outweighs any negatives.
A common mistake is that security cameras will last forever without a need to upgrade as technology improves but this is just not the case at all.

*Complex cabling is just another disadvantage that comes with high resolution security cameras. If you really want to record the scene going on in the premises then you need to take the help of DVR (digital video recorder) systems. Associating DVR systems along with CCTV security cameras is a brilliant idea but cabling complexities and the problem of managing of the cables will always be there.
These are best for you if you have only one location to constantly monitor. Most surveillance cameras are easy to install, and you can do the installation yourself. There are, however, other models that require professional help.
