WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. NO NEED TO USE BOTH Wi-fi AND PoE
Yes, you can't use both Wireless and PoE at same time. When you connect the IP camera to your router, you have to choose one of these, either Wi-fi or PoE.
Prior to deciding to buy an IP camera or a complete IP camera system, you should analysis the set up environment and check out which functions you want to attain.
WiFi or PoE, which is best? As a senior technician who has four years in video recording security industry, my response to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology which allows network devices transfer data through cellular signal (2.4GHz UHF strap, 5GHz SHF band).
Obviously, once the IP camera facilitates WiFi, the camera can connect your router without needing hardwired connection. Wireless can enable IP camera become lightweight, this is the advantage of WiFi.
But there are two disadvantages on WiFi, which can be; every electronic devices require power, that means your IP camera still requires cable television for connection.
Up to now, I haven't found any IP cams are able to operate with battery packs.
#3. HOW FAR DOES WI-FI REACH?
Limited WiFi transmitting distance is another problem.
What lengths does Wi-Fi reach? It's not easy to answer this question.
When talking about WiFi coverage, we've many things to consider including electricity rate of WiFi device, environment (in house or outdoor) and much more.
Typically, a home/office router (TP-Link) provides WiFi coverage extends to up to 10 meters interior.
When Wireless devices will work outdoor without hurdle, the transmission distance will be much considerably.
To increase the Wireless coverage or distance, you can mount WiFi gain access to 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 stands for Power over Ethernet, this is not a fresh technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power over one Ethernet cable television (Pet cat5/6) is the key feature of PoE technology.
As long as your IP camera supports PoE, you merely need to connect it to a PoE NVR or PoE switch, then it works. PoE technology enable IP cameras support plug-and-play assembly, which greatly reduced the unit installation procedures, and get rid of the necessity of electricity cable and supply.
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 vitality (lowest 44V DC and 350mA) to each device.
In order to provide power supply for high electric power intake devices, the IEEE connection made another new standard - IEEE802.3at, this standard also called PoE+ or PoE plus, provides up to 25.5 W of electricity.
PoE technology has been widely used in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Commercial devices
#5. Disadvantages AND Benefits OF POE TECHNOLOGY
Let's firstly discuss the advantages of PoE. A PoE IP camera can get the energy from the Ethernet cable tv, no need extra electric power cable or power.
The maximum connection distance is 100 meters, which is ten times than Wireless. Since data transmission is through wired wire, there is absolutely no signal interference, no sign 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 when compared to a traditional network transition, which increased a little on cost.
#6. Wi-fi VS POE
No best answer, only right solution. If you wish to install a unitary IP camera for home monitoring, you can opt for Wi-fi IP camera.
Ensuring the Wi-fi IP camera is installed within coverage of your WiFi router.
For more than one IP camera, PoE is recommended. PoE is much reliable than Wi-fi in terms of data transmitting.
Furthermore, an IP camera system predicated on PoE is a lot easier to manage, centralized ability solution becomes available e.g using uninterruptible power supply (UPS).
From my own investigation of surveillance market, I found that Wireless IP camcorders are trusted for non-professional inside home security, and PoE IP camcorders are installed for outdoor surveillance system. But if you choose WiFi IP Camera please read article below.
So how can you determine which cellular IP camera suits your preferences?
Firstly, establish the thing you need. Many customers often don't really know which kind of cordless IP camera suites and would satisfy their needs. As a result, they get sucked into buying wireless IP cameras that are beyond what they want.
Before clicking or picking on that item to buy, always consider: what conditions will the camera be situated in? (Hallway, outdoor, low light or smart); what perfection of data would you like to capture? (HD images with or without music) and most importantly, what is your budget?
Second of all, another essential feature to consider before getting yourself a radio IP camera is the pan and tilt range.
Of course, this feature will rely upon the environment where you would like to use the camera.
A wide skillet and tilt range is never an undesirable 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 on the market are digital, but you'll never fail to find one with optical focus.
Fourth, test the gear before purchase.
That is vital, particularly when you are buying from your neighborhood electric store.
Always obtain a test setup as this will allow you to look for the display quality of the camera.
Furthermore, it will give you an chance to learn how to set up the equipment in a proper manner to make certain you obtain the best image and music quality.
