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 Wi-fi and PoE at same time. Whenever you hook up 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 unit installation environment and check out which functions you want to attain.
WiFi or PoE, which is the greatest? As a older technician that has four years in video recording surveillance industry, my response to this question is PoE is the advised choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology that allows network devices transmit data through cordless sign (2.4GHz UHF band, 5GHz SHF group).
Obviously, after the IP camera helps Wireless, the camera can connect your router without needing hardwired connection. Wi-fi can permit IP camera become lightweight, this is actually the advantage of WiFi.
But there are two drawbacks on WiFi, that happen to be; every electronic devices require power, which means your IP camera still requires cable television for connection.
Up to now, I haven't found any IP video cameras are able to operate with power packs.
#3. WHAT LENGTHS Does indeed WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far will Wi-Fi reach? It's not easy to answer this question.
When discussing WiFi coverage, we've many things to consider including ability rate of Wireless device, environment (indoor or outdoor) plus more.
Typically, a home/office router (TP-Link) provides WiFi coverage grows to up to 10 meters interior.
When WiFi devices will work outdoor without hurdle, the transmission distance will be much significantly.
To extend the Wi-fi coverage or distance, you can set up WiFi gain access to point. This gain access to point (or hotspot) has a variety of about 20 meters (66 feet) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE stands for Power over Ethernet, this is not a new technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power over single Ethernet cable tv (Kitty5/6) is the key 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 cameras support plug-and-play unit installation, which greatly reduced the installation procedures, and get rid of the necessity of power cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum power rate is to 15.4 W of DC electric power (lowest 44V DC and 350mA) to each device.
In order to provide power for high power consumption devices, the IEEE relationship made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of ability.
PoE technology has been widely used in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Commercial devices
#5. Disadvantages AND Advantages OF POE TECHNOLOGY
Let's firstly discuss the advantages of PoE. A PoE IP camera can get the energy from the Ethernet wire, no need extra power cable or power.
The maximum connection distance is 100 meters, which is ten times than Wi-fi. Since data transmission is through wired wire, there is absolutely no signal interference, no sign jamming.
For properly working of PoE devices, Electric power 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 turn, which increased a little on cost.
#6. Wireless VS POE
No best answer, only right solution. If you wish to install one single IP camera for home monitoring, you can choose to use Wi-fi IP camera.
Ensuring the WiFi 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 conditions of data transmission.
Furthermore, an IP camera system predicated on PoE is a lot easier to take care of, centralized vitality solution becomes available e.g using uninterruptible power (UPS).
From my personal investigation of monitoring market, I came across that WiFi IP camcorders are trusted for non-professional in house security, and PoE IP surveillance cameras are installed for outdoor monitoring system. But if you select Wi-fi IP Camera please read article below.
So how will you determine which cordless IP camera suits your needs?
Firstly, establish what you need. Many buyers often don't really know which kind of cellular IP camera suites and would satisfy their needs. Because of this, 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 situated in? (Hallway, outdoor, low light or excellent); what detail of data do you want to capture? (HD images with or without audio) & most importantly, what's your budget?
Secondly, another essential feature to consider before sometimes a radio IP camera is the skillet and tilt range.
Certainly, this feature will rely upon the surroundings where you intend to use the camera.
A broad skillet and tilt range is never a bad thing.
Thirdly, zooming capacity for the cordless IP camera is also vital.
Make sure that you check the kind of zooming functionality, whether its optical or digital.
A lot of the IP cameras in the market are digital, but you'll never neglect to find one with optical zoom.
Fourth, test the equipment before purchase.
That is vital, specially when you are buying from your local digital store.
Always obtain a test set up as this will enable you to determine the picture quality of the camera.
In addition, it will give you an chance to learn how to set up the equipment in a proper manner to make sure that you obtain the best image and audio quality.
