When tied to a control system, televisions can automatically display images from cameras if, for example, motion is detected. Or the system can be programmed to display a picture-in-picture image from the front door whenever the doorbell is pressed.
Some cameras have web servers built in, so all you need is an Internet connection. They are more expensive than their simpler IP counterparts, but for single-camera installations this is an attractive option.
Motion sensing allows some cameras to send still frames to a specified email address when movement is detected.
A port will have to be opened on the website’s router to permit access to the camera. Stay away from port 80, as it is typically blocked by ISPs.
Use a Dynamic DNS (DDNS) service to preclude the need for an expensive static IP address. These services are available free of charge.
Many manufacturers have IP cameras that can automatically configure the router and provide the DDNS.
Many security monitoring stations support video monitoring. They can view your cameras remotely upon sensor activity or some other alarm event.
