WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. YOU DON'T NEED TO USE BOTH Wi-fi AND PoE
Yes, you can't use both WiFi and PoE at same time. While 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 set up environment and check out which functions you want to attain.
Wi-fi or PoE, which is a good? As a mature technician who has 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 transfer data through cordless transmission (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. Wireless can enable IP camera become portable, this is the advantage of WiFi.
But there are two disadvantages on WiFi, which are; every gadgets require power supply, which means your IP camera still requires cable connection for connection.
So far, I haven't found any IP video cameras have the ability to operate with power packs.
#3. WHAT LENGTHS Will WI-FI REACH?
Limited WiFi transmission distance is another problem.
What lengths does indeed Wi-Fi reach? It isn't easy to answer this question.
When discussing WiFi coverage, we have many things to consider including power rate of Wi-fi device, environment (inside or outdoor) and more.
Typically, a home/office router (TP-Link) can offer WiFi coverage gets to up to 10 meters inside.
When Wi-fi devices are working outdoor without hurdle, the transmitting distance will be much much.
To extend the Wi-fi coverage or distance, you can set up WiFi access point. This 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 means Power over Ethernet, this isn't a new technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power supply over single Ethernet cable (Kitty5/6) is the main 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 cams support plug-and-play unit installation, which greatly reduced the installation procedures, and get rid of the necessity of power cable and supply.
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 (minimal 44V DC and 350mA) to each device.
In order to provide power supply for high 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 surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Industrial devices
#5. Negative aspects AND Advantages OF POE TECHNOLOGY
Let's firstly discuss the features of PoE. A PoE IP camera can get the energy from the Ethernet cable television, no need extra ability cable or power supply.
The maximum connection distance is 100 meters, which is ten times than WiFi. Since data transmitting is through wired cable tv, there is absolutely no signal interference, no signal jamming.
For properly working of PoE devices, Vitality sourcing equipment (PSE) is vital component, it's rather a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is a lot expensive than a traditional network move, which increased a little on cost.
#6. Wi-fi 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.
Guaranteeing the Wireless IP camera is installed within coverage of your Wireless router.
For several IP camera, PoE is preferred. PoE is much reliable than Wireless in conditions of data transmission.
Furthermore, an IP camera system based on PoE is much easier to deal with, centralized power solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of security market, I found that WiFi IP surveillance cameras are widely used for non-professional indoors home security, and PoE IP cameras are installed for outdoor monitoring system. But if you choose WiFi IP Camera please read article below.
So how will you determine which cellular IP camera suits your preferences?
Firstly, establish the thing you need. Many clients often don't really know which type of cordless IP camera suites and would gratify their needs. As a result, they get sucked into buying wireless IP camcorders that are beyond what they need.
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 bright); what detail of data would you like to take? (HD images with or without sound) and most importantly, what's 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 would like to use the camera.
A wide skillet and tilt range is never an awful thing.
Thirdly, zooming capacity for the cordless IP camera is also vital.
Make sure that you check the sort of zooming ability, whether its optical or digital.
Most of the IP cameras in the market are digital, but you will never fail to find one with optical move.
Fourth, test the gear before purchase.
This is vital, particularly when you are buying from your neighborhood digital store.
Always request for a test setup as this will enable you to determine the display quality of the camera.
In addition, it will offer you an possibility to learn how to create the equipment in a proper manner to make certain you receive the best image and audio tracks quality.
