WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. NO NEED TO USE BOTH WIFI AND PoE
Yes, you can't use both Wireless and PoE at same time. While you hook up the IP camera to your router, you have to choose one of these, either Wi-fi or PoE.
Prior to deciding to buy an IP camera or a whole IP camera system, you should analysis the installation environment and investigate which functions you want to accomplish.
WiFi or PoE, which is best? As a older technician who may have four years in video tutorial monitoring industry, my answer to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology that allows network devices transmit data through wireless sign (2.4GHz UHF band, 5GHz SHF music group).
Obviously, after the IP camera facilitates Wi-fi, the camera can hook up your router without needing hardwired connection. Wi-fi can permit IP camera become lightweight, this is actually the advantage of Wi-fi.
But there are two drawbacks on WiFi, which can be; every gadgets require power, which means your IP camera still requires cable television for connection.
So far, I haven't found any IP cameras have the ability to operate with power packs.
#3. WHAT LENGTHS DOES WI-FI REACH?
Limited WiFi transmission distance is another problem.
What lengths does Wi-Fi reach? It's not easy to answer this question.
When discussing WiFi coverage, we've a lot of things to consider including ability rate of Wireless device, environment (indoors or outdoor) and more.
Typically, a home/office router (TP-Link) can provide WiFi coverage reaches up to 10 meters indoor.
When Wi-fi devices will work outdoor without barrier, the transmitting distance will be much significantly.
To extend the Wi-fi coverage or distance, you can set up WiFi gain access to point. This gain access to point (or hotspot) has a range around 20 meters (66 legs) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE stands for Power over Ethernet, this is not a fresh technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power over one Ethernet cable connection (Kitty5/6) is the main feature of PoE technology.
So long as your IP camera supports PoE, you just need to connect it to a PoE NVR or PoE switch, then it works. PoE technology permit IP camcorders support plug-and-play assembly, which greatly reduced the assembly procedures, and get rid of the necessity of power cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum power rate is to 15.4 W of DC vitality (minimal 44V DC and 350mA) to each device.
To be able to provide power supply for high electric power consumption devices, the IEEE relationship made another new standard - IEEE802.3at, this standard also called PoE+ or PoE plus, provides up to 25.5 W of electricity.
PoE technology has been trusted in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Commercial devices
#5. Drawbacks AND Positives OF POE TECHNOLOGY
Let's firstly discuss the advantages of PoE. A PoE IP camera can get the power from the Ethernet cable tv, no need extra vitality cable or power supply.
The maximum connection distance is 100 meters, which is ten times than Wireless. Since data transmission is through wired cable, there is absolutely no signal interference, no transmission jamming.
For properly working of PoE devices, Electric power sourcing equipment (PSE) is vital component, it's rather a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is much expensive when compared to a traditional network change, which increased just a little on cost.
#6. Wi-fi VS POE
No best answer, only right solution. If you wish to install one single IP camera for home monitoring, you can choose to use WiFi IP camera.
Guaranteeing the Wireless IP camera is installed within coverage of your Wi-fi router.
For several IP camera, PoE is recommended. PoE is much reliable than Wi-fi in conditions of data transmission.
Furthermore, an IP camera system based on PoE is much easier to deal with, centralized electricity solution becomes available e.g using uninterruptible power (UPS).
From my own investigation of monitoring market, I found that WiFi IP surveillance cameras are trusted for non-professional interior security, and PoE IP surveillance cameras are installed for outdoor security system. But if you choose WiFi IP Camera please read article below.
So how do you determine which cellular IP camera suits your needs?
Firstly, establish the thing you need. Many buyers often don't really know which type of wireless IP camera suites and would fulfill their needs. Because of this, they get sucked into buying cordless IP cameras that are beyond what they want.
Before clicking or picking on that item to buy, always consider: what conditions will the camera be situated in? (Hallway, outdoor, low light or shiny); what perfection of data would you like to record? (HD images with or without sound) and most importantly, what is your budget?
Second, another essential feature to consider before sometimes a wireless IP camera is the pan and tilt range.
Obviously, this feature will be based upon the environment where you want to use the camera.
A wide pan and tilt range is never an awful thing.
Thirdly, zooming capacity for the cellular IP camera is also essential.
Ensure that you check the type of zooming potential, whether its optical or digital.
A lot of the IP cameras on the market are digital, but you will never neglect to find one with optical move.
Fourth, test the gear before purchase.
That is vital, especially when you are buying from your neighborhood digital store.
Always request for a test set up as this will enable you to determine the picture quality of the camera.
Furthermore, it will give you an possibility to learn how to set up the gear in a proper manner to ensure that you have the best image and music quality.
