WIFI OR PoE FOR IP CAMERA, WHICH IS 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. Once you hook up the IP camera to your router, you have to choose one of these, either Wireless or PoE.
Before you decide to buy an IP camera or a whole IP camera system, you should analysis the installation environment and investigate which functions you want to attain.
Wireless or PoE, which is the best? As a mature technician who has four years in training video monitoring 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 cordless sign (2.4GHz UHF music group, 5GHz SHF music group).
Obviously, once the IP camera supports Wireless, the camera can hook up your router without using hardwired connection. Wireless can allow IP camera become lightweight, this is the advantage of WiFi.
But there are two disadvantages on WiFi, that happen to be; every gadgets require power, which means your IP camera still requires cable television for connection.
So far, I haven't found any IP cams are able to operate with electric batteries.
#3. HOW FAR DOES WI-FI REACH?
Limited WiFi transmission distance is another problem.
What lengths does Wi-Fi reach? It isn't easy to answer this question.
When talking about WiFi coverage, we've a lot of things to consider including power rate of Wireless device, environment (interior or outdoor) and even more.
Typically, a home/office router (TP-Link) provides WiFi coverage gets to up to 10 meters inside.
When Wi-fi devices will work outdoor without barrier, the transmitting distance will be much very good.
To extend the WiFi coverage or distance, you can set up WiFi access point. This access point (or hotspot) has a variety of about 20 meters (66 feet) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this isn't a fresh technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power supply over solo Ethernet cable (Kitty5/6) is the main feature of PoE technology.
So 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 enable IP video cameras support plug-and-play installation, which greatly reduced the assembly procedures, and eliminate the necessity of power cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum vitality rate is to 15.4 W of DC power (bare minimum 44V DC and 350mA) to each device.
To be able to provide power supply for high power usage 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 electricity.
PoE technology has been trusted in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Industrial devices
#5. Negatives AND Positives OF POE TECHNOLOGY
Let's first of all discuss the benefits of PoE. A PoE IP camera can get the power from the Ethernet cable, no need extra vitality cable or power.
The maximum connection distance is 100 meters, which is ten times than Wi-fi. Since data transmitting is through wired cable tv, there is no signal disturbance, no sign jamming.
For properly working of PoE devices, Power 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 much expensive when compared to a traditional network move, which increased a little on cost.
#6. WIFI VS POE
No best solution, only right solution. If you wish to install one single IP camera for home monitoring, you can choose to use Wi-fi IP camera.
Guaranteeing the Wireless IP camera is installed within coverage of your Wireless router.
For several IP camera, PoE is recommended. PoE is a lot reliable than WiFi in conditions of data transmission.
Furthermore, an IP camera system predicated on PoE is a lot easier to deal with, centralized electric power solution becomes available e.g using uninterruptible power (UPS).
From my own investigation of security market, I came across that Wireless IP camcorders are trusted for non-professional in house security, and PoE IP cams are installed for outdoor surveillance system. But if you select Wireless IP Camera please read article below.
So how will you determine which cordless IP camera suits your needs?
Firstly, establish the thing you need. Many potential buyers often don't really know which kind of wireless IP camera suites and would gratify their needs. Because of this, they get sucked into buying cellular IP video cameras 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 precision of data do you want to take? (HD images with or without sound) and most importantly, what is your budget?
Subsequently, another essential feature to consider before getting yourself a wireless IP camera is the pan and tilt range.
Of course, this feature will be based upon the surroundings where you want 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 essential.
Ensure that you check the kind of zooming potential, whether its optical or digital.
A lot of the IP cameras in the market are digital, but you will never neglect to find one with optical focus.
Fourth, test the equipment before purchase.
This is vital, especially when you are buying from your local electric store.
Always obtain a test set up as this will allow you to look for the picture quality of the camera.
Furthermore, it will give you an opportunity to learn how to set up the equipment in an effective manner to make certain you find the best image and music quality.
