WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. NO NEED TO USE BOTH Wireless AND PoE
Yes, you can't use both Wi-fi and PoE at same time. While you connect the IP camera to your router, you have to choose one of these, either Wireless 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 accomplish.
Wireless or PoE, which is the best? As a older technician who may have four years in video recording surveillance industry, my answer to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology that allows network devices transfer data through cordless signal (2.4GHz UHF band, 5GHz SHF group).
Obviously, once the IP camera helps WiFi, the camera can connect your router without using hardwired connection. Wi-fi can allow IP camera become lightweight, this is actually the advantage of Wireless.
But there are two downsides on WiFi, which are; every electronic devices require power supply, that means your IP camera still requires wire for connection.
So far, I haven't found any IP video cameras have the ability to operate with power packs.
#3. WHAT LENGTHS Will 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 have many things to consider including electric power rate of Wireless device, environment (indoor or outdoor) and more.
Typically, a home/office router (TP-Link) can offer WiFi coverage reaches up to 10 meters indoors.
When WiFi devices are working outdoor without barrier, the transmission distance will be much much.
To increase the Wireless coverage or distance, you can set up WiFi access point. This gain access to point (or hotspot) has a range around 20 meters (66 toes) 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 was launched by Cisco in 1999. Transmitting both data and power over sole Ethernet cable tv (Feline5/6) is the key feature of PoE technology.
So 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 allow IP cams support plug-and-play unit installation, 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 provide maximum electricity rate is to 15.4 W of DC vitality (minimum amount 44V DC and 350mA) to each device.
In order to provide power for high power use devices, the IEEE relationship made another new standard - IEEE802.3at, this standard also called PoE+ or PoE plus, provides up to 25.5 W of power.
PoE technology has been widely used in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Professional devices
#5. Downsides AND Advantages OF POE TECHNOLOGY
Let's first of all discuss the features of PoE. A PoE IP camera can get the power from the Ethernet cable, no need extra electric power cable or power supply.
The maximum interconnection distance is 100 meters, which is ten times than Wi-fi. Since data transmitting is through wired cable, there is no signal interference, no sign jamming.
For properly working of PoE devices, Electric power sourcing equipment (PSE) is vital component, it's rather a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is much expensive than a traditional network move, which increased a little on cost.
#6. WIFI VS POE
No best answer, only right solution. If you want to install a unitary IP camera for home monitoring, you can opt for Wi-fi IP camera.
Ensuring the WiFi IP camera is installed within coverage of your Wireless router.
For more than one IP camera, PoE is recommended. PoE is a lot reliable than Wireless in conditions of data transmission.
Furthermore, an IP camera system predicated on PoE is a lot easier to deal with, centralized electric power solution becomes available e.g using uninterruptible power supply (UPS).
From my own investigation of monitoring market, I came across that Wi-fi IP video cameras are trusted for non-professional in house home security, and PoE IP cams are installed for outdoor security system. But if you select Wi-fi IP Camera please read article below.
So how do you really determine which cordless IP camera suits your preferences?
Firstly, establish the thing you need. Many purchasers often don't really know which type of cordless IP camera suites and would satisfy their needs. Because of this, they get sucked into buying cordless IP surveillance cameras that are beyond what they need.
Before clicking or picking on that item to buy, always consider: what conditions will the camera be situated in? (Hallway, outdoor, low light or excellent); what perfection of data do you want to capture? (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 wireless IP camera is the skillet and tilt range.
Naturally, this feature will depend on the environment where you want to use the camera.
A broad skillet and tilt range is never a terrible thing.
Thirdly, zooming capacity for the cordless IP camera is also vital.
Make sure that you check the sort of zooming ability, whether its optical or digital.
A lot of the IP cameras in the market are digital, but you will never neglect to find one with optical focus.
Fourth, test the equipment before purchase.
This is vital, especially when you are buying from your neighborhood electronic digital store.
Always obtain a test set up as this will allow you to look for the picture quality of the camera.
In addition, it will offer you an chance to learn how to create the gear in a proper manner to make sure that you obtain the best image and audio tracks quality.
