2.Q: Can I use my old security cameras mixed with new ones?
A: Yes, providing certain conditions are met. Even with the same color type, some older cameras and some newer cameras mixed together can cause problems because of very different image synchronizing systems. In this event, you can get interference between one camera image and another. Color cameras are more prone to this type of problem.
3.Q: Analog VS IP, For what applications should I consider IP?
A: IP cameras should be considered for large installation sites that already have a high bandwidth network installed - especially if the cameras will be spread out over a wide area, or if wireless cameras will be used.
For large installations with many cameras, some installers still prefer a multiple DVR solution to an IP solution. Software is bundled with higher-end DVRs that allows you to view and record cameras from multiple DVRs. The multiple DVR solution also provides better failover protection. If the network goes down in an IP based system, video is lost from all the cameras. If the network goes down in an analog system, the DVRs are still recording the cameras.Related Products
