WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. YOU DON'T NEED TO USE BOTH Wireless AND PoE
Yes, you can't use both Wireless and PoE at same time. After you hook up the IP camera to your router, you have to choose one of them, either WiFi or PoE.
Before you decide to buy an IP camera or a whole IP camera system, you should analysis the set up environment and check out which functions you want to accomplish.
Wireless or PoE, which is the foremost? As a older technician who has four years in training video security industry, my answer to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology which allows network devices transmit data through wireless indication (2.4GHz UHF strap, 5GHz SHF music group).
Obviously, once the IP camera supports Wi-fi, the camera can connect your router without needing hardwired connection. WiFi can permit IP camera become portable, this is the advantage of Wireless.
But there are two disadvantages on WiFi, which are; every gadgets require power, which means your IP camera still requires cable tv for connection.
So far, I haven't found any IP cameras have the ability to operate with batteries.
#3. HOW FAR Will WI-FI REACH?
Limited WiFi transmitting distance is another problem.
How far does Wi-Fi reach? It isn't easy to answer this question.
When talking about WiFi coverage, we have a lot of things to consider including electricity rate of Wireless device, environment (in house or outdoor) plus more.
Typically, a home/office router (TP-Link) can provide WiFi coverage gets to up to 10 meters indoor.
When Wi-fi devices will work outdoor without hurdle, the transmission distance will be much much.
To increase the WiFi coverage or distance, you can install WiFi gain access to point. This access 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 new technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power over solitary Ethernet cable (Kitty5/6) is the primary feature of PoE technology.
As long as your IP camera helps PoE, you merely need to connect it to a PoE NVR or PoE switch, then it works. PoE technology permit IP surveillance cameras support plug-and-play installation, which greatly reduced the unit installation procedures, and eliminate the necessity of vitality cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can offer maximum vitality rate is to 15.4 W of DC power (minimum amount 44V DC and 350mA) to each device.
To be able to provide power for high electric power usage 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 monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Professional devices
#5. Drawbacks AND Benefits 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, no need extra power cable or power supply.
The maximum connection distance is 100 meters, which is ten times than Wireless. Since data transmitting is through wired wire, there is no signal disturbance, no signal jamming.
For properly working of PoE devices, Ability 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 a lot expensive when compared to a traditional network transition, which increased a little on cost.
#6. Wireless VS POE
No best solution, only right solution. If you want to install a unitary IP camera for home monitoring, you can choose to use WiFi IP camera.
Making sure the WiFi IP camera is installed within coverage of your Wireless router.
For more than one 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 control, centralized electricity solution becomes available e.g using uninterruptible power (UPS).
From my own investigation of security market, I came across that Wi-fi IP cameras are widely used for non-professional inside security, and PoE IP camcorders are installed for outdoor security system. But if you select Wi-fi IP Camera please read article below.
So how do you determine which wireless IP camera suits your preferences?
Firstly, establish what you need. Many potential buyers often don't really know which type of cordless IP camera suites and would satisfy their needs. As a result, they get sucked into buying cordless IP camcorders that are beyond what they want.
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 dazzling); what accuracy of data do you want to get? (HD images with or without audio tracks) and 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 environment where you would like to use the camera.
A wide pan and tilt range is never a negative thing.
Thirdly, zooming capability of the cellular IP camera is also vital.
Ensure that you check the sort of zooming potential, whether its optical or digital.
Most of the IP cameras in the market are digital, but you'll never neglect to find one with optical move.
Fourth, test the equipment before purchase.
That is vital, in particular when you are buying from your local electronic digital store.
Always obtain a test installation as this will permit you to determine the picture quality of the camera.
Furthermore, it will offer you an chance to learn how to create the gear in an effective manner to make sure that you receive the best image and music quality.
