1- One of the most problematic issues is the High
2- The high cost of the hardware and software storage. This is not only about the cost of the hardware, it is also about the large number of hardware is needed to store the high mount of data. It increases as people are tending more and more to use digital cameras and digital technology. Well, the cost of hardware is not the companies' big concern nowadays, that is because managers who used to keep their data saved in offsite locations that are managed by specialized companies in data storage are aware of their badly need to these data onsite.
3- Higher bandwidth: megapixel IP cameras require higher bandwidth which is the main concern of the companies, that is, can the backbone of the company's network handle the new and the large increase in the required bandwidth?

8- The probability of the signals being jammed by other devices is highly to occur. This can be related to the lack of DVR's support where the megapixel IP camera's signal can be picked up by the DVR itself.
9- In case of internet disconnection, you will lose the captured images or recorded videos which may cause you lot of trouble.
10- The transition of signals and streaming videos into your megapixel IP camera depend on the speed of your internet.
