As the growing of business and the increasing awareness of security, IP cameras are widely deployed in areas like schools, public areas and even at home. All these arouse the increasing demand for PoE (power over Ethernet) switches which enabling big benefits for IP surveillance system. However, many users may ask a question: how to choose a PoE switch for my IP cameras? 8-port PoE switch or 24-port gigabit PoE switch? Cisco PoE switch or Netgear PoE switch? This post intends to explore the necessary considerations for buying PoE switch. Understanding How PoE Switch Works for IP Cameras As we know, power consumption of different IP cameras is different. The power consumption of PTZ (pan-tilt zoom) cameras is up to 20W, while other IP cameras like indoor/outdoor dome IP cameras may just consume as little as 3 or 4W. In addition, PoE switches transmit both data and power for PoE-enabled devices via a single network/Ethernet cables such as Cat5e, Cat6 and Cat6a. Usually, PoE switch c...

Purpose built for converged networks where video, voice and data are carried over a single network platform, PoE switches with 8 port, 24 port and 48 port represents an ideal solutions for different size networks like home or SMBs (small and mid-size business networks). 24-port gigabit PoE switch is a relatively commonly used network switch, which in turn cause hot discussions in forums and communities. Then what to consider when choosing a 24-port PoE switch? What’s the popular 24-port gigabit PoE switch to select? This post will give an answer. Considerations to Choose a 24-port PoE Switch As we know, the basic types of a network switch are managed switch, smart managed switch and unmanaged switch. Usually, managed and smart managed switches are an optimal choice for SMB applications because of its better control of networks. Power budget —PoE switches are designed to power devices like IP cameras, VoIP phone, AP, etc. The power the 24-port PoE switch provides should m...

When network designers build their networks, there is a common problem that they may meet: whether to stack switches or not. Because, limited by the switch port counts, designers have to get more switches or stack switches to meet network build requirements. In the article, the stack of 48-port PoE switch will be used as examples to explore how to achieve optimized network performance through switch stacking, and when network designers need to stack their network switches. How to Decide Whether Switch Stacking Is Need? Switch stacking is to connect two or a group of network switches to form a single stack unit that can be managed in a simple way. In this way, available switch ports are increasing as well as management simplicity. For example, in an small business network (PoE is necessary), if 48 gigabit ports are needed, two 24-port gigabit PoE switches can be stacked to achieve the target. Of course, one 48 port PoE gigabit switch also can be used. However, whether to choose...
