Security IP Surveillance Quick Reference Guide

This Quick Reference Guide lists EtherWAN’s best-selling network connectivity products for security & surveillance. Through a few simple steps, you’ll be able to select the right EtherWAN product according to your requirements. If you need further assistance, please don’t hesitate to contact our sales department.

Information needed to select the proper PoE (Power over Ethernet) Switch:

1. How many cameras are you connecting?
2. Are the devices 10/100 Fast Ethernet (FE) or 10/100/1000 Gigabit Ethernet?
3. Will you need room for additional cameras (expansion) in the future?
   a. It is always a good practice to have some extra PoE ports available for future expansion.
4. Are you connecting an NVR (Network Video Recorder) and network uplink to a central office?

   a. If yes, you need an extra port for the NVR and a port for network uplink.
   b. If no, and the NVR is somewhere else on the network, you need at least one port for network uplink
   c. Calculate Total Bandwidth requirement for all cameras in order to choose the correct uplink port. (Calculation is based on resolution, frame rate, video compression, number of video streaming sessions)

5. What is the maximum power draw (wattage) of each camera

   a. Refer to the datasheet for the camera or the manufacturer’s website.
   b. If the wattage of all devices is below 15.4W, then an IEEE802.3af PoE switch should be sufficient.
   c. If the wattage of any connected device is greater than 15.4W, then choose an IEEE802.3at PoE switch.
   d. If the wattage of any device is greater than 30W, then consider purchasing an ultra-PoE switch.
   e. Add up total wattage from all cameras. This figure will be used to determine the required PoE power budget.

6. Make sure you select a switch that has a large enough PoE Power Budget to cover the total power draw calculated in #5-e above. It is a good practice to allow for 20% overage on the powerbudget. Example: Each camera draws 12 Watts x 8 cameras = 96W. After adding a 20% margin, a 115.2W minimum PoE budget is recommended.
7. Managed vs. Unmanaged switch? We always recommend at least Web-Smart management,  as thisallows for troubleshooting as well as remote power cycling of any individual camera.
8. Installation location:

   a. Indoor deployment with air conditioning: Operating Temperature 0 ~ 45°C (0 ~ 113°F).
   b. Indoor Deployment without air conditioning: Operating Temperature -10 ~ 60°C (14 ~ 140°F).
   c. Outdoor Deployment: Operating Temperature -40 ~ 75°C (-40 ~ 167°F).
