What are the requirements and Specifications needed for Poe switch for IP cameras?

In this post, we explain the requirements and specifications needed for PoE switch and IP cameras.

A PoE switch provides power supply and data connection via network cables like Cat5, Cat5e, and Cat6 in PoE IP camera systems. In today’s business and home office, whatever the industry or location, using PoE switches for IP cameras to ensure the safety of people and businesses is prevalent and widespread. Usually, for different IP camera systems, PoE switches with different ports are deployed. This article will explore these situations in detail.

A PoE injector can also power IP cameras and save more space. However, what if there are many devices, say ten IP cameras, needing to be connected? Under this condition, a PoE switch that has more ports will provide the optimal choice.

PoE standard was raised and subsequently approved as a standard after the innovation based on the previous PoE (802.3af), PoE+ (802.3at), and type 3 PoE++ (802.3bt) up to 60W. The exact information about 802.3bt type 4 high power PoE is shown in the following chart:

If you want to power an IP camera, you will require a total power per port of 30W. This can be better understood with an example. A 24-port Gigabit PoE managed switch with a power envelope of 360W allows it to add IP cameras until this power limit is reached.

If there are 2 SFP ports available, multiple switches can be connected as well. Data transmission speed has improved with the aid of PoE technology. PoE may deliver up to 2.5 to 5Gbps data over 100 meters by adopting Cat5 and Cat6 patch cables.

As far as Power Management is concerned, by implementing PoE technology, the user can rely on the centralized or centrally-managed uninterrupted power supply (UPS) for backup power. On the other hand, Wi-Fi-based IP cameras utilize individual power management systems.

Remember that if the power threshold is surpassed and the devices are not obtaining enough power, they might not boot uprightly. In some instances, you may need to connect 20 devices in which all of which have varied power requirements.

Every time, the security departments are not capable of buying all new cameras. Most times, these devices are added and replaced when the power budget is flexible. Therefore, the cameras have varied power requirements and capabilities.

Another aspect to consider is the image recording. For example, you are using a 24-port managed PoE switch. The administrators can program every specific port depending on how images from the particular IP cameras are being recorded. Those cameras might record whenever the motion sensor senses movement and leads to erratic power rewuirements.

On the other hand, IP cameras that are recording 24/7 will need slightly more power. This programmable flexibility based on each port assists network administrators in fulfilling every device linked to the switch.
