WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. YOU DON'T NEED TO USE BOTH WIFI 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 these, either Wi-fi or PoE.
Before you decide to buy an IP camera or a whole IP camera system, you should analysis the assembly environment and investigate which functions you want to attain.
WiFi or PoE, which is the better? As a mature technician who have four years in video tutorial security 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 signal (2.4GHz UHF music group, 5GHz SHF band).
Obviously, after the IP camera helps WiFi, the camera can hook up your router without needing hardwired connection. WiFi can permit IP camera become portable, this is the advantage of Wireless.
But there are two disadvantages on WiFi, which are; every gadgets require power, which 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 batteries.
#3. WHAT LENGTHS Will WI-FI REACH?
Limited WiFi transmission distance is another problem.
What lengths will Wi-Fi reach? It isn't easy to answer this question.
When talking about WiFi coverage, we have a lot of things to consider including vitality rate of Wireless device, environment (indoors or outdoor) plus more.
Typically, a home/office router (TP-Link) can provide WiFi coverage extends to up to 10 meters interior.
When Wi-fi devices are working outdoor without hurdle, the transmission distance will be much much.
To increase the Wi-fi coverage or distance, you can install WiFi gain access to point. This access point (or hotspot) has a variety of about 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 supply over single Ethernet cable (Pet cat5/6) is the key feature of PoE technology.
As long as your IP camera facilitates PoE, you just need to connect it to a PoE NVR or PoE switch, then it works. PoE technology allow IP surveillance cameras support plug-and-play unit installation, which greatly reduced the set up procedures, and get rid of the necessity of electric power cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can provide maximum electricity rate is to 15.4 W of DC power (minimum 44V DC and 350mA) to each device.
In order to provide power for high electricity consumption devices, the IEEE association 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 widely used in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Professional devices
#5. Disadvantages AND Advantages OF POE TECHNOLOGY
Let's first of all discuss the benefits of PoE. A PoE IP camera can get the energy from the Ethernet cable tv, no need extra ability 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 indication jamming.
For properly working of PoE devices, Electricity 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 a little on cost.
#6. WIFI VS POE
No best answer, only right solution. If you want to install a unitary IP camera for home monitoring, you can opt for Wireless IP camera.
Making sure the Wireless IP camera is installed within coverage of your Wireless router.
For several IP camera, PoE is preferred. PoE is much reliable than WiFi in conditions of data transmission.
Furthermore, an IP camera system based on PoE is much easier to manage, centralized vitality solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of monitoring market, I came across that Wi-fi IP cameras are trusted for non-professional interior security, and PoE IP cameras are installed for outdoor security system. But if you select WiFi 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 customers often don't really know which kind of cordless IP camera suites and would fulfill their needs. As a result, they get sucked into buying cordless IP surveillance 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 dazzling); what accuracy of data would you like to catch? (HD images with or without audio tracks) and most importantly, what is your budget?
Secondly, another essential feature to consider before sometimes a radio IP camera is the skillet and tilt range.
Certainly, this feature will depend on the surroundings where you would like to use the camera.
A broad skillet and tilt range is never a bad thing.
Thirdly, zooming capacity for the wireless IP camera is also vital.
Make sure that you check the sort of zooming capabilities, whether its optical or digital.
A lot of the IP cameras in the market are digital, but you'll never fail to find one with optical zoom.
Fourth, test the gear before purchase.
This is vital, specially when you are buying from your neighborhood electronic store.
Always request for a test installation 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 find the best image and audio tracks quality.
