Pan-Tilt-Zoom or PTZ Web cameras bring two powerful punches to the benefit of the digital video security and surveillance world. Not only can these cameras allow your system to reap the powerful benefit of camera movement (the first punch) but also make use of the Internet as a means for networking (punch number two).
PTZ cameras have been used in the video security and surveillance world for quite some time; even when the systems operated in a totally analog format. However, as technology has increased, cameras have become more powerful in function and lighter in weight as well as more versatile in application. Now, digital video cameras with PTZ functions are much more easily controlled.

Tired of not being able to see things that go “bump” in the dark? If that’s the case, you need a night vision wireless security camera. These cameras take advantage of the latest technology in digital camera security systems, are easy to install, and are reasonably priced as well.
Can a night vision wireless security camera actually “see” in the dark? Well, indirectly the answer is yes. Although the camera doesn’t actually “see” in the dark, it uses infrared illumination to light the target area of the camera. This infrared illumination is actually invisible to the human eye, so we can’t see it, but the camera can. Before we get ahead of ourselves let’s back up and start at the beginning.

Almost every DVR has the ability to control a multitude of devices using the RS485 protocol. RS485 uses 2 wires to send and receive data to and from these devices. All the devices in an RS485 “network” are connected in parallel with one another. This is a very simple form of communication and relies mainly on the address that is given to each device.
