WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. NO NEED TO USE BOTH Wi-fi AND PoE
Yes, you can't use both WiFi and PoE at same time. When you connect the IP camera to your router, you have to choose one of these, either Wireless or PoE.
Prior to deciding to buy an IP camera or a whole IP camera system, you should analysis the assembly environment and check out which functions you want to attain.
WiFi or PoE, which is a good? As a mature technician who may have four years in video recording security 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 cellular sign (2.4GHz UHF group, 5GHz SHF music group).
Obviously, after the IP camera supports Wi-fi, the camera can hook up your router without using hardwired connection. Wi-fi can permit IP camera become portable, this is the advantage of Wi-fi.
But there are two disadvantages on WiFi, that happen to be; every gadgets require power supply, that means your IP camera still requires cable tv for connection.
So far, I haven't found any IP camcorders are able to operate with electric batteries.
#3. HOW FAR DOES 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 discussing WiFi coverage, we have a lot of things to consider including ability rate of WiFi device, environment (interior or outdoor) and more.
Typically, a home/office router (TP-Link) provides WiFi coverage grows to up to 10 meters inside.
When WiFi devices will work outdoor without barrier, the transmission distance will be much far.
To increase the WiFi coverage or distance, you can set up WiFi gain access to point. This gain access to point (or hotspot) has a variety around 20 meters (66 ft) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE stands for Power over Ethernet, this isn't a new technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power over sole Ethernet wire (Kitten5/6) is the key feature of PoE technology.
So long as your IP camera helps PoE, you merely need to connect it to a PoE NVR or PoE switch, then it works. PoE technology enable IP cameras support plug-and-play set up, which greatly reduced the unit installation procedures, and eliminate the necessity of vitality cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum ability rate is to 15.4 W of DC electricity (minimum amount 44V DC and 350mA) to each device.
In order to provide power supply for high electricity ingestion 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 electric power.
PoE technology has been trusted in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Commercial devices
#5. Negatives AND Advantages 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 electricity cable or power supply.
The maximum connection distance is 100 meters, which is ten times than WiFi. Since data transmission is through wired cable television, there is no signal disturbance, no transmission jamming.
For properly working of PoE devices, Ability 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 a lot expensive when compared to a traditional network move, which increased a little on cost.
#6. WIFI VS POE
No best answer, only right solution. If you wish to install one single IP camera for home monitoring, you can opt for Wireless IP camera.
Making sure the Wireless IP camera is installed within coverage of your WiFi router.
For more than one IP camera, PoE is preferred. PoE is a lot reliable than Wireless in conditions 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 own investigation of security market, I came across that WiFi IP camcorders are widely used for non-professional in house home security, and PoE IP video cameras are installed for outdoor monitoring system. But if you select Wi-fi IP Camera please read article below.
So how does one determine which cellular IP camera suits your preferences?
Firstly, establish the thing you need. Many clients often don't really know which type of wireless IP camera suites and would meet their needs. Because of this, they get sucked into buying cellular IP 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 located in? (Hallway, outdoor, low light or excellent); what precision of data would you like to catch? (HD images with or without sound) and most importantly, what is your budget?
Secondly, another essential feature to consider before getting yourself a radio IP camera is the pan and tilt range.
Needless to say, this feature will rely upon the environment where you would like to use the camera.
A broad skillet and tilt range is never an awful thing.
Thirdly, zooming capacity for the wireless 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'll never neglect to find one with optical focus.
Fourth, test the equipment before purchase.
That is vital, especially when you are buying from your neighborhood digital store.
Always request for a test installation as this will allow you to determine the picture quality of the camera.
In addition, it will offer you an opportunity to learn how to create the equipment in an effective manner to make sure that you have the best image and sound quality.
