Enable Time Stamp

Check this check box to display the time from the internal clock of the IP

 

 

camera as an overlay on the video image from the IP camera.

 

 

Enable Text Display

Check this check box to display designated text as an overlay on the video

 

 

image from the IP camera, and enter alphanumeric text of up to 20

 

 

characters.

 

 

This option can be useful for identifying this IP camera in an installation

 

 

with several IP cameras.

 

 

Day/Night Vision

 

 

 

 

Switch Mode

 

Choose the day/night vision mode for the IP camera:

 

 

Auto—IP camera automatically switches between day and night mode

 

 

based on the lighting condition threshold that you specify.

 

 

Day—IP camera always remains in day mode.

 

 

Night—IP camera always remains in night mode.

 

 

Night schedule—IP camera switches to and from Night mode based on

 

 

the Start and End times.

 

 

Note If you configure a night schedule, make sure that the time on the IP

 

 

camera is set correctly.

 

 

Validation Time

If the Switch Mode option is set to Auto, specify the time that the camera

 

 

waits before switching Day/Night modes. The light level must continually

 

 

exceed the threshold for the duration of the validation time to trigger a

 

 

transition between the modes.

 

 

For example, if the Validation Time is set to 5 seconds and the current light

 

 

level exceeds the Night/Day Threshold for 5 seconds, the camera switches

 

 

mode. However, if the light level falls below the threshold during the

 

 

Validation Time, the timer resets and the camera remains in the same mode.

 

 

The default value for Validation Time is 2 seconds.

 

 

Note If a camera experiences lighting conditions that cause it to switch

 

 

continuously between Day and Night modes three times within 20

 

 

minutes (as the result of a low light scene with excessive IR

 

 

illumination or the thresholds being configured too close together),

 

 

the camera locks in to its last state for 20 minutes.

 

 

For example, if the first transition is from Day to Night, the camera

 

 

will switch from Day to Night to Day to Night and then remain in

 

 

Night mode for 20 minutes. If the first transition is from Night to

 

 

Day, the camera will switch from Night to Day to Night to Day and

 

 

then remain in Day mode for 20 minutes.

 

 

To unlock the 20 minute hold period, manually configure the camera

 

 

to Day mode, then Night mode, then Day mode, and then Auto mode.

CIVS-IPC-2500, 2500 Series specifications

The Cisco Systems 2500 Series routers are a series of versatile, feature-rich networking devices designed to address the needs of various enterprises and small to medium-sized businesses. Released in the early 1990s, the 2500 Series quickly became a backbone solution for organizations seeking reliable and efficient networking capabilities.

One of the defining characteristics of the Cisco 2500 Series is its modular architecture, which allows businesses to customize their routers based on specific networking needs. This modularity accommodates various interface cards, enabling the integration of different protocols and connection types, including serial, Ethernet, and WAN interfaces. As a result, organizations can tailor their routers to support diverse applications while ensuring optimal performance.

The Cisco 2500 Series supports several advanced routing protocols, including RIP, OSPF, EIGRP, and BGP. This support provides flexibility for network design and ensures that users can implement scalable solutions as their business grows. Moreover, the routers come equipped with robust security features, including access control lists (ACLs) and support for VPNs, making them suitable for organizations that require a secure network environment.

A notable feature of the Cisco 2500 Series is its support for Quality of Service (QoS). This functionality allows organizations to prioritize certain types of traffic, ensuring that critical applications, such as VoIP or video conferencing, receive the necessary bandwidth and minimal latency. This is particularly beneficial for businesses that rely on real-time communications and need to maintain high levels of service quality.

Additionally, the implementation of Cisco’s internetworking technologies, such as IP and frame relay, enhances the overall performance and versatility of the 2500 Series routers. These technologies enable efficient data transmission and improve network reliability, which is essential for organizations with complex networking requirements.

In summary, the Cisco Systems 2500 Series routers are known for their modular design, support for multiple routing protocols, robust security features, and advanced QoS capabilities. Their ability to adapt to different networking environments makes them an ideal choice for businesses looking to enhance their connectivity and streamline their operations. Even decades after their introduction, the 2500 Series remains a relevant player in the networking market, demonstrating Cisco's commitment to providing effective solutions for diverse industries.
