WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. YOU DON'T NEED TO USE BOTH Wireless AND PoE
Yes, you can't use both Wi-fi and PoE at same time. If you hook up the IP camera to your router, you have to choose one of them, either WiFi or PoE.
Prior to deciding to buy an IP camera or a complete IP camera system, you should analysis the assembly environment and check out which functions you want to accomplish.
WiFi or PoE, which is the greatest? As a senior technician that has four years in video security industry, my answer to this question is PoE is the advised choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology which allows network devices transfer data through wireless transmission (2.4GHz UHF strap, 5GHz SHF group).
Obviously, once the IP camera helps WiFi, the camera can connect your router without using hardwired connection. WiFi can enable IP camera become portable, this is actually the advantage of Wireless.
But there are two disadvantages on WiFi, which are; every gadgets require power, that means your IP camera still requires cable tv for connection.
Up to now, I haven't found any IP camcorders are able to operate with battery power.
#3. HOW FAR DOES WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far does 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 Wi-fi device, environment (in house or outdoor) plus more.
Typically, a home/office router (TP-Link) provides WiFi coverage extends to up to 10 meters in house.
When Wi-fi devices are working outdoor without hurdle, the transmitting distance will be much far.
To extend the WiFi coverage or distance, you can mount WiFi gain access to point. This access point (or hotspot) has a range 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 over one Ethernet wire (Feline5/6) is the main feature of PoE technology.
As long as your IP camera supports PoE, you just need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology enable IP cameras support plug-and-play unit installation, which greatly reduced the unit installation procedures, and eliminate the necessity of power cable and supply.
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 ability (lowest 44V DC and 350mA) to each device.
To be able to provide power supply for high electricity 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 vitality.
PoE technology has been trusted in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Industrial devices
#5. Negatives AND PROS OF POE TECHNOLOGY
Let's first of all 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.
The maximum connection distance is 100 meters, which is ten times than Wi-fi. Since data transmitting is through wired cable television, there is absolutely no signal interference, no transmission jamming.
For properly working of PoE devices, Electricity 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 when compared to a traditional network move, which increased just a little on cost.
#6. Wi-fi VS POE
No best solution, only right solution. If you wish to install one single IP camera for home monitoring, you can opt for WiFi IP camera.
Making sure the WiFi IP camera is installed within coverage of your WiFi router.
For more than one IP camera, PoE is preferred. PoE is much reliable than Wi-fi in conditions of data transmitting.
Furthermore, an IP camera system based on PoE is much easier to take care of, centralized power solution becomes available e.g using uninterruptible power (UPS).
From my personal investigation of monitoring market, I found that Wi-fi IP cams are widely used for non-professional indoors security, and PoE IP surveillance cameras are installed for outdoor monitoring system. But if you choose Wireless IP Camera please read article below.
So how can you determine which wireless IP camera suits your needs?
Firstly, establish what you need. Many buyers often don't really know which kind of wireless IP camera suites and would fulfill their needs. Because of this, they get sucked into buying wireless IP camcorders 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 dazzling); what accuracy of data do you want to catch? (HD images with or without music) & most importantly, what's your budget?
Secondly, another essential feature to consider before sometimes a wireless IP camera is the skillet and tilt range.
Certainly, this feature will depend on the surroundings where you want 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.
Ensure that you check the kind of zooming ability, whether its optical or digital.
Most 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.
This is vital, especially when you are buying from your neighborhood digital store.
Always request for a test set up as this will allow you to determine the picture quality of the camera.
Furthermore, it will offer you an chance to learn how to create the equipment in a proper manner to make certain you receive the best image and music quality.
