Chapter 2 Getting Started

Adjusting Back Focus on the IP Camera

Adjusting Back Focus on the IP Camera

To obtain the sharpest image from the camera, you may need to adjust its back focus. This adjustment is useful if the focus control on a lens does not allow you to obtain a sharp enough image.

To adjust the back focus, perform the following steps while viewing video from the camera. For information about viewing video, see Chapter 4, “Viewing Live Video.”

Procedure

Step 1 With a lens attached to the IP camera, use the 0.9 mm Allen wrench that is supplied with the IP camera to loosen the focus ring hex screw.

This screw is on the bottom of the camera just behind the focus ring.

Step 2 Adjust the back focus by aiming the IP camera at an object that is at least 15 feet (4.5 meters) away and rotating the focus ring to obtain a clear image as follows:

For a variable-focus lens, obtain a sharp picture in both wide-angle and telephoto positions.

For a zoom lens, ensure that the object of interest remains in focus throughout the entire zoom range of the lens.

Step 3 Use the Allen wrench to tighten the focus ring hex screw.

Powering the IP Camera On or Off

The IP camera does not include an on/off switch. You power it on or off by connecting it to or disconnecting it from a power source. When you power off the IP camera, it retains configuration information.

To power on the IP camera, take either of these actions:

Use an STP category 5 or higher network cable to connect the IP camera to a network switch that provides 802.3af compliant PoE

Use the appropriate power adapter to connect the IP camera to a wall outlet

To power off the IP camera, take either of these actions:

If the IP camera is receiving PoE, disconnect the network cable

If the IP camera is receiving power through the power adapter, unplug the adapter from the wall or disconnect it from the camera

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.
