Benefits of IP Cameras:
Secure – IP cameras have encryption built right into them providing for a more secure network. Interference is also not a problem with IP-based models.
Can utilize existing wiring – Because IP-based cameras act as their own network device, you can often take advantage of existing network wiring within your business. This can make the installation task much easier.
Remote Access – IP cameras are better suited for remote surveillance needs.
