What is a network camera?
Also called "IP cameras" or "ethernet cameras", a network camera transmits its audio/video (A/V) signal via standard computer networking CAT5 cable. It has software built-in on its chip that allows anyone on the network to view the A/V data - just like a computer on a network. There is no special software needed to view the camera. You can view the images in an internet browser by pulling up the ip address assigned to the camera. To record the video, you can use software such as our Optiview-IP Virtual DVR software on any computer on the network.
What is the difference between an analog camera and a network camera?
An ordinary security camera transmits its A/V data via RCA or COAX cable to a monitor or a recording device (either a VCR or DVR). If you want to view this data remotely you would need to purchase a special kind of DVR that converts the image data to digital and has networking software to broadcast this digital data over a network.
What are the major features to look for in network cameras?
The features to look for in a network camera are MPEG4 compression (see below), quality of construction, resolution, frames per second (fps), chip type, cost, and availability and quality of the software. Other features to look for are audio support, motion detection, and time stamp text overlay (critical if used in court). Also, look at the warrantee and technical support.
