WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. YOU DON'T NEED TO USE BOTH WIFI AND PoE
Yes, you can't use both Wi-fi and PoE at same time. After you hook up 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 unit installation environment and check out which functions you want to achieve.
WiFi or PoE, which is the best? As a senior technician who have four years in video security industry, my answer to this question is PoE is the recommended choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology which allows network devices transfer data through cordless indication (2.4GHz UHF group, 5GHz SHF strap).
Obviously, once the IP camera supports Wireless, the camera can connect your router without needing hardwired connection. WiFi can permit IP camera become portable, this is actually the advantage of Wi-fi.
But there are two disadvantages on WiFi, which are; every gadgets require power, 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 batteries.
#3. HOW FAR DOES WI-FI REACH?
Limited WiFi transmitting distance is another problem.
How far does Wi-Fi reach? It's not easy to answer this question.
When talking about WiFi coverage, we've a lot of things to consider including electricity rate of Wi-fi device, environment (in house or outdoor) and even more.
Typically, a home/office router (TP-Link) can provide WiFi coverage extends to up to 10 meters inside.
When Wireless devices will work outdoor without barrier, the transmission distance will be much far.
To extend the Wi-fi coverage or distance, you can mount WiFi gain access to point. This gain access to point (or hotspot) has a variety of about 20 meters (66 toes) indoors and a greater 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 one Ethernet cable connection (Cat5/6) is the key feature of PoE technology.
So long as your IP camera facilitates PoE, you merely need to connect it to a PoE NVR or PoE switch, then it works. PoE technology allow IP video cameras support plug-and-play assembly, which greatly reduced the assembly procedures, and eliminate the necessity of vitality cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can offer maximum electric power rate is to 15.4 W of DC electric power (least 44V DC and 350mA) to each device.
In order to provide power supply for high electric power consumption 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 electric power.
PoE technology has been trusted in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Industrial devices
#5. Negative aspects AND Positives OF POE TECHNOLOGY
Let's firstly discuss the advantages of PoE. A PoE IP camera can get the power from the Ethernet cable tv, 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 connection, there is absolutely no signal disturbance, no transmission 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 a lot expensive than a traditional network transition, which increased just 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 opt for Wi-fi 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 a lot reliable than WiFi in terms of data transmitting.
Furthermore, an IP camera system based on PoE is much easier to take care of, centralized electricity solution becomes available e.g using uninterruptible power supply (UPS).
From my own investigation of surveillance market, I came across that Wireless IP cams are widely used for non-professional indoor security, and PoE IP cams are installed for outdoor monitoring system. But if you select Wireless IP Camera please read article below.
So how will you determine which wireless IP camera suits your needs?
Firstly, establish the thing you need. Many customers often don't really know which type of cellular IP camera suites and would fulfill their needs. As a result, 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 situated in? (Hallway, outdoor, low light or excellent); what accuracy of data would you like to take? (HD images with or without audio) and most importantly, what's your budget?
Second of all, another essential feature to consider before getting yourself a radio IP camera is the pan and tilt range.
Naturally, this feature will rely upon the environment where you intend to use the camera.
A wide pan and tilt range is never an undesirable thing.
Thirdly, zooming capability of the wireless IP camera is also vital.
Make sure that you check the kind of zooming functionality, 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 zoom.
Fourth, test the gear before purchase.
This is vital, especially when you are buying from your neighborhood electronic store.
Always request for a test setup as this will enable you to determine the picture quality of the camera.
In addition, 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.
