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. While you hook up the IP camera to your router, you have to choose one of them, either WiFi or PoE.
Before you decide to buy an IP camera or a complete IP camera system, you should analysis the unit installation environment and research which functions you want to achieve.
Wireless or PoE, which is a good? As a older technician who has four years in video surveillance industry, my answer to this question is PoE is the advised choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology which allows network devices transfer data through cordless indication (2.4GHz UHF strap, 5GHz SHF band).
Obviously, after the IP camera supports Wireless, the camera can connect your router without using hardwired connection. Wi-fi can allow IP camera become lightweight, this is the advantage of Wireless.
But there are two disadvantages on WiFi, that happen to be; every gadgets require power supply, that means your IP camera still requires cable connection for connection.
So far, I haven't found any IP cams have the ability to operate with power packs.
#3. WHAT LENGTHS Will WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far does indeed Wi-Fi reach? It isn't easy to answer this question.
When discussing WiFi coverage, we've a lot of things to consider including ability rate of Wireless device, environment (in house or outdoor) and much more.
Typically, a home/office router (TP-Link) can provide WiFi coverage reaches up to 10 meters indoors.
When Wireless devices will work outdoor without hurdle, the transmission distance will be much way.
To increase the Wireless coverage or distance, you can mount WiFi gain access to point. This gain access to point (or hotspot) has a variety around 20 meters (66 foot) 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 premiered by Cisco in 1999. Transmitting both data and power supply over one Ethernet cable connection (Feline5/6) is the key feature of PoE technology.
As long as your IP camera facilitates PoE, you merely need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology permit IP cameras support plug-and-play assembly, which greatly reduced the assembly procedures, and get rid of the necessity of power cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides 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 vitality use 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 vitality.
PoE technology has been trusted in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Professional devices
#5. Drawbacks AND Positives OF POE TECHNOLOGY
Let's first of all discuss the benefits of PoE. A PoE IP camera can get the energy from the Ethernet wire, no need extra electricity cable or power.
The maximum connection distance is 100 meters, which is ten times than Wireless. Since data transmitting is through wired cable, there is absolutely no signal disturbance, no transmission jamming.
For properly working of PoE devices, Ability sourcing equipment (PSE) is essential 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 swap, which increased a little on cost.
#6. WIFI VS POE
No best solution, only right solution. If you wish to install a unitary IP camera for home monitoring, you can opt for WiFi 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 terms of data transmission.
Furthermore, an IP camera system predicated on PoE is much easier to control, centralized vitality solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of surveillance market, I came across that Wireless IP surveillance cameras are trusted for non-professional inside security, and PoE IP video cameras are installed for outdoor surveillance system. But if you select WiFi IP Camera please read article below.
So how do you really determine which wireless IP camera suits your preferences?
Firstly, establish the thing you need. Many customers often don't really know which kind of wireless IP camera suites and would meet their needs. Because of this, they get sucked into buying wireless IP cameras 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 glowing); what perfection of data do you want to record? (HD images with or without audio tracks) and most importantly, what is your budget?
Secondly, another essential feature to consider before getting yourself a radio IP camera is the skillet and tilt range.
Certainly, this feature will be based upon the environment where you intend to use the camera.
A broad skillet and tilt range is never an awful thing.
Thirdly, zooming capacity for the wireless IP camera is also essential.
Make sure that you check the kind of zooming ability, whether its optical or digital.
Most of the IP cameras in the market are digital, but you'll never fail to find one with optical move.
Fourth, test the gear before purchase.
That is vital, particularly when you are buying from your local electronic digital store.
Always obtain a test setup as this will enable you to determine the display quality of the camera.
In addition, it will give you an possibility to learn how to create the gear in a proper manner to make certain you get the best image and sound quality.
