WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. YOU DON'T NEED TO USE BOTH Wi-fi AND PoE
Yes, you can't use both Wireless and PoE at same time. Whenever you hook up the IP camera to your router, you have to choose one of them, either WiFi or PoE.
Prior to deciding to buy an IP camera or a whole IP camera system, you should analysis the installation environment and investigate which functions you want to accomplish.
WiFi or PoE, which is the foremost? As a mature technician that has four years in training video security industry, my response 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 wireless signal (2.4GHz UHF strap, 5GHz SHF music group).
Obviously, once the IP camera helps WiFi, the camera can hook up your router without using hardwired connection. Wireless can permit IP camera become portable, this is actually the advantage of Wireless.
But there are two disadvantages on WiFi, which are; every gadgets require power, that means your IP camera still requires cable connection for connection.
Up to now, I haven't found any IP video cameras are able to operate with battery power.
#3. HOW FAR DOES WI-FI REACH?
Limited WiFi transmitting distance is another problem.
What lengths does indeed Wi-Fi reach? It's not easy to answer this question.
When talking about WiFi coverage, we have a lot of things to consider including ability rate of Wi-fi device, environment (indoors or outdoor) plus more.
Typically, a home/office router (TP-Link) can offer WiFi coverage gets to up to 10 meters inside.
When Wi-fi devices are working outdoor without barrier, the transmission distance will be much very good.
To increase the Wireless coverage or distance, you can install WiFi gain access to point. This gain access to point (or hotspot) has a range around 20 meters (66 toes) 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 supply over one Ethernet cable tv (Kitten5/6) is the main feature of PoE technology.
So 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 enable IP camcorders support plug-and-play assembly, which greatly reduced the unit installation procedures, and eliminate the necessity of power cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can provide maximum electric power rate is to 15.4 W of DC electric power (lowest 44V DC and 350mA) to each device.
To be able to provide power for high electric power intake devices, the IEEE association 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 surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Commercial devices
#5. Disadvantages AND Positives 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 television, 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 transmission jamming.
For properly working of PoE devices, Vitality 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 a lot expensive than a traditional network switch, which increased just a little on cost.
#6. WIFI VS POE
No best solution, only right solution. If you want to install one single IP camera for home monitoring, you can opt for WiFi IP camera.
Guaranteeing the Wireless IP camera is installed within coverage of your WiFi router.
For several IP camera, PoE is preferred. PoE is a lot reliable than Wireless in terms of data transmission.
Furthermore, an IP camera system predicated on PoE is much easier to deal with, centralized electric power solution becomes available e.g using uninterruptible power (UPS).
From my personal investigation of security market, I found that Wireless IP cams are trusted for non-professional interior security, and PoE IP 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 the thing you need. Many clients often don't really know which kind of cordless IP camera suites and would fulfill 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 ask yourself: what conditions will the camera be located in? (Hallway, outdoor, low light or glowing); what detail of data would you like to get? (HD images with or without audio) & most importantly, what's your budget?
Subsequently, 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 want to use the camera.
A wide skillet and tilt range is never a negative thing.
Thirdly, zooming capability of the cordless IP camera is also essential.
Make sure that you check the kind of zooming capabilities, 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 gear before purchase.
This is vital, particularly when you are buying from your neighborhood electronic digital store.
Always request for a test set up as this will permit 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 ensure that you obtain the best image and audio tracks quality.
