Connection Issues using TKIP Protocol
TKIP, or Temporary Key Integrity Protocol, was meant to replace the insecure WEP encryption system in found in most Wi-Fi networks. TKIP also turned out to be insecure, so a new standard called WPA2 was created, which uses AES, or Advanced Encryption Standard. AES provides a much more secure connection because it uses longer encryption keys which increases the efficiency and security of your Wi-Fi connection.
Since TKIP is a legacy protocol, most newer Amcrest model cameras will require the use of an AES encryption when connecting to a Wi-Fi network. Failure to use proper encryption can cause numerous connection issues between your camera and your Wi-Fi network. Many routers today provide WPA2-PSK (TKIP), WPA2-PSK (AES), and WPA2-PSK (TKIP/AES) encryption as options.
For assistance with connecting your router to the proper protocol, please refer to the router manufacturer's user manual, or from the manufacture directly.
