WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. NO NEED TO USE BOTH Wireless AND PoE
Yes, you can't use both Wi-fi and PoE at same time. After you connect the IP camera to your router, you have to choose one of them, either Wi-fi or PoE.
Before you decide to buy an IP camera or a whole IP camera system, you should analysis the set up environment and investigate which functions you want to accomplish.
Wi-fi or PoE, which is the foremost? As a older technician that has four years in training video security industry, my response to this question is PoE is the recommended choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology that allows network devices transfer data through cellular transmission (2.4GHz UHF music group, 5GHz SHF music group).
Obviously, after the IP camera helps WiFi, the camera can hook up your router without needing hardwired connection. Wi-fi can allow IP camera become portable, this is the advantage of Wireless.
But there are two disadvantages on WiFi, which are; every electronic devices require power supply, which means your IP camera still requires wire for connection.
Up to now, I haven't found any IP camcorders are able to operate with power packs.
#3. HOW FAR Does indeed WI-FI REACH?
Limited WiFi transmitting distance is another problem.
How far will Wi-Fi reach? It isn't easy to answer this question.
When talking about WiFi coverage, we have many things to consider including ability rate of Wireless device, environment (indoors or outdoor) and more.
Typically, a home/office router (TP-Link) can offer WiFi coverage gets to up to 10 meters interior.
When Wireless devices will work outdoor without barrier, the transmitting distance will be much far.
To increase the WiFi coverage or distance, you can mount WiFi gain access to point. Such an access point (or hotspot) has a range of about 20 meters (66 foot) 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 supply over solitary Ethernet cable connection (Cat5/6) is the main feature of PoE technology.
As long as your IP camera facilitates PoE, you just need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology enable IP video cameras support plug-and-play installation, 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 can offer maximum electric power rate is to 15.4 W of DC electricity (minimum amount 44V DC and 350mA) to each device.
In order to provide power for high vitality consumption 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 vitality.
PoE technology has been widely used in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Professional devices
#5. CONS AND Positives OF POE TECHNOLOGY
Let's firstly discuss the benefits of PoE. A PoE IP camera can get the power from the Ethernet wire, no need extra electric power cable or power supply.
The maximum interconnection distance is 100 meters, which is ten times than Wi-fi. Since data transmission is through wired cable tv, there is no signal interference, no transmission jamming.
For properly working of PoE devices, Ability sourcing equipment (PSE) is essential component, it can be a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is a lot expensive than a traditional network turn, which increased just a little on cost.
#6. Wi-fi VS POE
No best answer, only right solution. If you wish to install a unitary IP camera for home monitoring, you can choose to use WiFi IP camera.
Making sure the Wireless IP camera is installed within coverage of your Wi-fi router.
For more than one IP camera, PoE is recommended. PoE is a lot reliable than Wi-fi in terms of data transmitting.
Furthermore, an IP camera system predicated on PoE is much easier to manage, centralized power solution becomes available e.g using uninterruptible power (UPS).
From my personal investigation of monitoring market, I found that Wi-fi IP surveillance cameras are trusted for non-professional in house security, and PoE IP camcorders are installed for outdoor security system. But if you choose Wi-fi IP Camera please read article below.
So how does one determine which wireless IP camera suits your preferences?
Firstly, establish the thing you need. Many clients often don't really know which kind of cellular IP camera suites and would gratify their needs. Because of this, they get sucked into buying cordless IP cams that are beyond what they need.
Before clicking or picking on that item to buy, always consider: what conditions will the camera be situated in? (Hallway, outdoor, low light or glowing); what accuracy of data would you like to catch? (HD images with or without audio) & most importantly, what's your budget?
Second of all, another essential feature to consider before getting yourself a wireless IP camera is the skillet and tilt range.
Needless to say, this feature will rely upon the surroundings where you would like to use the camera.
A broad skillet and tilt range is never an undesirable thing.
Thirdly, zooming capability of the cellular IP camera is also essential.
Make sure that you check the sort of zooming functionality, whether its optical or digital.
Most of the IP cameras in the market are digital, but you will never neglect to find one with optical zoom.
Fourth, test the equipment before purchase.
That is vital, specially when you are buying from your neighborhood digital store.
Always obtain a test setup as this will allow you to look for the picture quality of the camera.
Furthermore, it will offer you an possibility to learn how to set up the equipment in a proper manner to make certain you receive the best image and music quality.
