| There are are number of reasons why you | | | | interlacing. High resolution analog camera are not |

| proven its worth in performance. | | | | images are created from two interlaced fields. |
| The IP tetwork camera has existed since 1996. | | | | While the analog camera produces blurry images |
| During its release, network cameras lagged a mile | | | | of fast-moving objects, the IP network camera |
| behind analog cameras in professionalism. In the | | | | provides crystal clear images because the whole |
