WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. NO NEED TO USE BOTH Wi-fi AND PoE
Yes, you can't use both Wireless and PoE at same time. Once 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 investigate which functions you want to achieve.
WiFi or PoE, which is the better? As a mature technician who has four years in video tutorial security industry, my answer to this question is PoE is the advised choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology which allows network devices transfer data through cordless sign (2.4GHz UHF music group, 5GHz SHF music group).
Obviously, once the IP camera facilitates Wi-fi, the camera can connect your router without using hardwired connection. WiFi can allow IP camera become lightweight, this is the advantage of WiFi.
But there are two downsides on WiFi, which are; every electronic devices require power supply, which means your IP camera still requires cable for connection.
So far, I haven't found any IP cams have the ability to operate with electric batteries.
#3. WHAT LENGTHS Will WI-FI REACH?
Limited WiFi transmitting distance is another problem.
What lengths will Wi-Fi reach? It isn't easy to answer this question.
When discussing WiFi coverage, we've a lot of things to consider including vitality rate of Wireless device, environment (inside or outdoor) and more.
Typically, a home/office router (TP-Link) can offer WiFi coverage reaches up to 10 meters inside.
When Wireless devices are working outdoor without barrier, the transmitting distance will be much far.
To increase the WiFi coverage or distance, you can mount WiFi access point. This gain access to point (or hotspot) has a variety 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 over one Ethernet cable (Cat5/6) is the primary feature of PoE technology.
As long as your IP camera helps PoE, you just need to connect it to a PoE NVR or PoE switch, then it works. PoE technology enable IP surveillance cameras support plug-and-play unit installation, which greatly reduced the assembly procedures, and get rid of the necessity of ability 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 power (lowest 44V DC and 350mA) to each device.
To be able to provide power supply for high vitality utilization 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 ability.
PoE technology has been widely used in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Professional devices
#5. Negatives AND Positives OF POE TECHNOLOGY
Let's firstly discuss the features of PoE. A PoE IP camera can get the energy from the Ethernet wire, no need extra ability cable or power supply.
The maximum interconnection distance is 100 meters, which is ten times than Wi-fi. Since data transmission is through wired cable connection, there is no signal disturbance, no signal jamming.
For properly working of PoE devices, Vitality sourcing equipment (PSE) is essential component, it can be a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is much expensive than a traditional network swap, which increased a little on cost.
#6. Wi-fi VS POE
No best solution, only right solution. If you want to install a unitary IP camera for home monitoring, you can opt for Wireless IP camera.
Ensuring the Wi-fi IP camera is installed within coverage of your WiFi router.
For more than one IP camera, PoE is preferred. PoE is a lot reliable than WiFi in terms of data transmission.
Furthermore, an IP camera system predicated on PoE is a lot easier to control, centralized power solution becomes available e.g using uninterruptible power supply (UPS).
From my own investigation of security market, I found that Wi-fi IP cams are trusted for non-professional indoor security, and PoE IP camcorders are installed for outdoor monitoring system. But if you choose WiFi IP Camera please read article below.
So how do you determine which cordless IP camera suits your needs?
Firstly, establish what you need. Many potential buyers often don't really know which type of cellular IP camera suites and would meet their needs. Because of this, they get sucked into buying wireless IP cams 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 excellent); what accuracy of data would you like to take? (HD images with or without audio) & most importantly, what's your budget?
Second, another essential feature to consider before sometimes a wireless IP camera is the pan and tilt range.
Naturally, this feature will be based upon the surroundings where you want to use the camera.
A broad skillet and tilt range is never a negative thing.
Thirdly, zooming capability of the wireless IP camera is also essential.
Make sure that you check the kind of zooming capabilities, whether its optical or digital.
Most of the IP cameras on the market are digital, but you will never neglect to find one with optical zoom.
Fourth, test the gear before purchase.
This is vital, specially when you are buying from your local electric store.
Always request for a test setup 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 equipment in a proper manner to ensure that you receive the best image and sound quality.
