WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. NO NEED TO USE BOTH WIFI AND PoE
Yes, you can't use both Wi-fi and PoE at same time. When you hook up the IP camera to your router, you have to choose one of these, 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 research which functions you want to attain.
Wi-fi or PoE, which is the greatest? As a mature technician who have four years in training video surveillance industry, my answer to this question is PoE is the advised choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology that allows network devices transfer data through cordless sign (2.4GHz UHF strap, 5GHz SHF group).
Obviously, once the IP camera facilitates Wireless, the camera can connect your router without needing hardwired connection. Wireless can enable IP camera become portable, this is the advantage of WiFi.
But there are two downsides on WiFi, that happen to be; every electronic devices require power, which means your IP camera still requires cable for connection.
Up to now, I haven't found any IP cams are able to operate with battery power.
#3. HOW FAR DOES WI-FI REACH?
Limited WiFi transmission distance is another problem.
What lengths will Wi-Fi reach? It isn't easy to answer this question.
When talking about WiFi coverage, we've many things to consider including electricity rate of Wireless device, environment (interior or outdoor) and more.
Typically, a home/office router (TP-Link) can provide WiFi coverage extends to up to 10 meters indoor.
When WiFi devices are working outdoor without hurdle, the transmitting distance will be much much.
To increase the WiFi coverage or distance, you can install WiFi access point. Such an access point (or hotspot) has a range around 20 meters (66 feet) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE stands for 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 sole Ethernet cable television (Cat5/6) is the primary feature of PoE technology.
As long as your IP camera helps PoE, you merely need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology allow IP camcorders support plug-and-play assembly, which greatly reduced the set up procedures, and eliminate the necessity of ability cable and offer.
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 power (bare minimum 44V DC and 350mA) to each device.
In order to provide power supply for high power use 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 widely used in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Professional devices
#5. Drawbacks 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 connection, no need extra electricity cable or power.
The maximum connection distance is 100 meters, which is ten times than WiFi. Since data transmitting is through wired cable connection, there is absolutely no signal disturbance, no indication 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 turn, which increased just a little on cost.
#6. WIFI VS POE
No best answer, only right solution. If you wish to install a unitary IP camera for home monitoring, you can opt for WiFi IP camera.
Making sure the WiFi IP camera is installed within coverage of your Wireless router.
For several IP camera, PoE is recommended. PoE is much reliable than Wireless in terms of data transmission.
Furthermore, an IP camera system predicated on PoE is much easier to manage, centralized electric power solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of security market, I came across that WiFi IP cams are trusted for non-professional in house security, and PoE IP camcorders are installed for outdoor security system. But if you choose Wireless IP Camera please read article below.
So how does one determine which wireless IP camera suits your preferences?
Firstly, establish the thing you need. Many potential buyers often don't really know which kind of cordless IP camera suites and would meet their needs. As a result, they get sucked into buying wireless IP cams 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 excellent); what accuracy of data would you like to catch? (HD images with or without audio) and most importantly, what's your budget?
Second, another essential feature to consider before sometimes a radio IP camera is the skillet and tilt range.
Of course, this feature will be based upon the environment where you intend to use the camera.
A broad 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 functionality, whether its optical or digital.
A lot of the IP cameras on the market are digital, but you'll never fail to find one with optical zoom.
Fourth, test the gear before purchase.
That is vital, specially when you are buying from your local electric store.
Always obtain a test set up as this will allow you to determine the display quality of the camera.
Furthermore, it will give you an possibility to learn how to set up the gear in a proper manner to make sure that you get the best image and sound quality.
