The following table shows the maximum transmission distance of cables with certain diameter when the 24V AC power source voltage loss rate is below 10%.
6 Cable Diameter (12V DC) and Transmission Distance The recommended transmission distances are for reference only, and the actual conditions shall prevail. The following table shows the maximum transmission distance of cables with certain diameter when the 12V DC power source voltage loss rate is below 10%.
7 Cable Diameter (24V DC) and Transmission Distance The recommended transmission distances are for reference only, and the actual conditions shall prevail. The following table shows the maximum transmission distance of cables with certain diameter when the 24V DC power source voltage loss rate is below 10%.
8 Cable Diameter (30V DC) and Transmission Distance The recommended transmission distances are for reference only, and the actual conditions shall prevail. The following table shows the maximum transmission distance of cables with certain diameter when the 30V DC power source voltage loss rate is below 20%.
9 Cable Diameter (36V DC) and Transmission Distance The recommended transmission distances are for reference only, and the actual conditions shall prevail. The following table shows the maximum transmission distance of cables with certain diameter when the 36V DC power source voltage loss rate is below 25%.
Appendix 1 Cybersecurity Recommendations Cybersecurity is more than just a buzzword: it’s something that pertains to every device that is connected to the internet. IP video surveillance is not immune to cyber risks, but taking basic steps toward protecting and strengthening networks and networked appliances will make them less susceptible to attacks.

Cybersecurity Recommendations 4. Enable Account Lock The account lock feature is enabled by default, and we recommend you to keep it on to guarantee the account security. If an attacker attempts to log in with the wrong password several times, the corresponding account and the source IP address will be locked.

Cybersecurity Recommendations you need to save the log for a long time, it is recommended that you enable the network log function to ensure that the critical logs are synchronized to the network log server for tracing. 14. Construct a Safe Network Environment In order to better ensure the safety of equipment and reduce potential cyber risks, we recommend: Disable the port mapping function of the router to avoid direct access to...
