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. When you hook up the IP camera to your router, you have to choose one of these, either WiFi or PoE.
Before you decide to buy an IP camera or a complete IP camera system, you should analysis the set up environment and investigate which functions you want to attain.
Wi-fi or PoE, which is the better? As a older technician who may have four years in training video surveillance industry, my answer to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology which allows network devices transmit data through wireless signal (2.4GHz UHF band, 5GHz SHF music group).
Obviously, once the IP camera helps WiFi, the camera can hook up your router without using hardwired connection. WiFi can permit IP camera become lightweight, this is actually the advantage of WiFi.
But there are two disadvantages on WiFi, which are; every electronic devices require power, that means your IP camera still requires cable tv for connection.
So far, I haven't found any IP cams have the ability to operate with batteries.
#3. HOW FAR Will WI-FI REACH?
Limited WiFi transmitting distance is another problem.
What lengths does indeed Wi-Fi reach? It's not easy to answer this question.
When talking about WiFi coverage, we've a lot of things to consider including electric power rate of Wireless device, environment (inside or outdoor) and much more.
Typically, a home/office router (TP-Link) can offer WiFi coverage reaches up to 10 meters indoor.
When WiFi devices are working outdoor without barrier, the transmitting distance will be much very good.
To extend the Wi-fi coverage or distance, you can mount WiFi access point. This gain access to point (or hotspot) has a range of about 20 meters (66 feet) indoors and a larger 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 supply over solitary Ethernet cable tv (Pet cat5/6) is the key feature of PoE technology.
As long as your IP camera supports PoE, you merely need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology allow IP camcorders support plug-and-play unit installation, which greatly reduced the installation procedures, and get rid of the necessity of ability cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum ability rate is to 15.4 W of DC ability (bare minimum 44V DC and 350mA) to each device.
In order to provide power supply for high power intake devices, the IEEE connection made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of electricity.
PoE technology has been widely used in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Commercial devices
#5. Disadvantages 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, no need extra electric power cable or power.
The maximum connection distance is 100 meters, which is ten times than Wireless. Since data transmission is through wired cable connection, there is no signal interference, no signal jamming.
For properly working of PoE devices, Electric power sourcing equipment (PSE) is vital component, it can be a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is much expensive when compared to a traditional network transition, which increased just a little on cost.
#6. WIFI VS POE
No best solution, only right solution. If you want to install a unitary IP camera for home monitoring, you can choose to use Wi-fi IP camera.
Ensuring the WiFi IP camera is installed within coverage of your Wireless router.
For several IP camera, PoE is recommended. PoE is a lot reliable than WiFi in terms of data transmitting.
Furthermore, an IP camera system based on PoE is much easier to manage, 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 camcorders are trusted for non-professional inside home security, and PoE IP cameras are installed for outdoor monitoring system. But if you select Wireless IP Camera please read article below.
So how would you determine which cordless IP camera suits your needs?
Firstly, establish the thing you need. Many clients often don't really know which type of wireless IP camera suites and would fulfill their needs. As a result, they get sucked into buying cellular IP cams 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 smart); what accuracy of data do you want to get? (HD images with or without music) & most importantly, what's your budget?
Second of all, another essential feature to consider before getting yourself a radio IP camera is the skillet and tilt range.
Needless to say, this feature will depend on the environment where you would like to use the camera.
A broad skillet and tilt range is never a bad thing.
Thirdly, zooming capability of the cellular IP camera is also vital.
Ensure that you check the kind of zooming capability, whether its optical or digital.
A lot of the IP cameras on the market are digital, but you'll never neglect to find one with optical focus.
Fourth, test the gear before purchase.
That is vital, specially when you are buying from your neighborhood electric store.
Always request for a test set up as this will enable you to determine the picture quality of the camera.
In addition, it will give you an chance to learn how to set up the equipment in a proper manner to make sure that you find the best image and music quality.
