WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. YOU DON'T NEED TO USE BOTH Wireless AND PoE
Yes, you can't use both WiFi and PoE at same time. Whenever you connect the IP camera to your router, you have to choose one of them, either WiFi or PoE.
Before you decide to buy an IP camera or a whole IP camera system, you should analysis the unit installation environment and investigate which functions you want to attain.
Wireless or PoE, which is the greatest? As a mature technician who have four years in video recording 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 indication (2.4GHz UHF music group, 5GHz SHF band).
Obviously, after the IP camera supports WiFi, the camera can hook up your router without using hardwired connection. Wi-fi can permit IP camera become portable, this is actually the advantage of Wireless.
But there are two downsides on WiFi, that happen to be; every gadgets require power supply, that means your IP camera still requires cable television for connection.
Up to now, I haven't found any IP cams have the ability to operate with electric batteries.
#3. WHAT LENGTHS Will WI-FI REACH?
Limited WiFi transmitting distance is another problem.
How far does Wi-Fi reach? It's not easy to answer this question.
When discussing WiFi coverage, we have many things to consider including power rate of WiFi device, environment (indoors or outdoor) plus more.
Typically, a home/office router (TP-Link) provides WiFi coverage reaches up to 10 meters interior.
When WiFi devices are working outdoor without barrier, the transmitting distance will be much considerably.
To extend the Wi-fi coverage or distance, you can set up WiFi access point. Such an gain access to point (or hotspot) has a range of about 20 meters (66 ft) 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 premiered by Cisco in 1999. Transmitting both data and power supply over one Ethernet wire (Feline5/6) is the main feature of PoE technology.
As 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 video cameras support plug-and-play installation, which greatly reduced the assembly procedures, and eliminate the necessity of vitality cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can offer maximum electricity rate is to 15.4 W of DC electric power (bare minimum 44V DC and 350mA) to each device.
In order to provide power supply for high electric power utilization devices, the IEEE relationship made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of ability.
PoE technology has been trusted in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Professional devices
#5. CONS AND Benefits OF POE TECHNOLOGY
Let's first of all discuss the benefits of PoE. A PoE IP camera can get the power from the Ethernet wire, no need extra ability cable or power supply.
The maximum connection distance is 100 meters, which is ten times than Wi-fi. Since data transmission is through wired cable connection, there is absolutely no signal interference, no sign jamming.
For properly working of PoE devices, Power sourcing equipment (PSE) is essential component, it's rather a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is much expensive than a traditional network change, which increased just a little on cost.
#6. Wireless 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 Wi-fi IP camera.
Making sure the WiFi IP camera is installed within coverage of your Wireless router.
For more than one IP camera, PoE is preferred. PoE is a lot reliable than Wireless in terms of data transmission.
Furthermore, an IP camera system predicated on PoE is much easier to control, centralized electric power solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of security market, I came across that WiFi IP video cameras are trusted for non-professional inside security, and PoE IP surveillance cameras are installed for outdoor security system. But if you select Wi-fi IP Camera please read article below.
So how do you really determine which wireless IP camera suits your preferences?
Firstly, establish the thing you need. Many customers often don't really know which type of cordless IP camera suites and would fulfill their needs. Because of this, they get sucked into buying cellular IP video cameras that are beyond what they want.
Before clicking or picking on that item to buy, always ask yourself: what conditions will the camera be situated in? (Hallway, outdoor, low light or bright); what perfection of data would you like to record? (HD images with or without audio) and most importantly, what is your budget?
Subsequently, another essential feature to consider before getting yourself a wireless IP camera is the skillet and tilt range.
Obviously, this feature will depend on the surroundings where you want to use the camera.
A wide skillet and tilt range is never a negative thing.
Thirdly, zooming capability of the cellular IP camera is also essential.
Ensure that you check the kind of zooming functionality, whether its optical or digital.
Most of the IP cameras in the market are digital, but you'll never neglect to find one with optical focus.
Fourth, test the equipment before purchase.
That is vital, specially when you are buying from your neighborhood digital store.
Always obtain a test set up as this will permit you to determine the picture quality of the camera.
In addition, it will offer you an opportunity to learn how to set up the gear in an effective manner to make certain you receive the best image and sound quality.
