WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. YOU DON'T NEED TO USE BOTH Wi-fi AND PoE
Yes, you can't use both Wi-fi and PoE at same time. Whenever you connect 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 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 best? As a older technician who may have four years in video tutorial monitoring industry, my answer 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 wireless indication (2.4GHz UHF music group, 5GHz SHF music group).
Obviously, once the IP camera facilitates Wi-fi, the camera can hook up your router without using hardwired connection. Wireless can allow IP camera become portable, this is the advantage of Wi-fi.
But there are two downsides on WiFi, that are; every gadgets require power supply, which means your IP camera still requires wire for connection.
So far, I haven't found any IP camcorders have the ability to operate with power packs.
#3. WHAT LENGTHS Does indeed WI-FI REACH?
Limited WiFi transmission distance is another problem.
What lengths does Wi-Fi reach? It isn't easy to answer this question.
When talking about WiFi coverage, we've a lot of things to consider including electricity rate of WiFi device, environment (inside or outdoor) plus more.
Typically, a home/office router (TP-Link) can provide WiFi coverage gets to up to 10 meters interior.
When Wi-fi devices will work outdoor without barrier, the transmission distance will be much far.
To increase the WiFi coverage or distance, you can mount WiFi gain access to point. This gain access to point (or hotspot) has a variety around 20 meters (66 legs) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE means 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 solo Ethernet cable (Kitten5/6) is the primary feature of PoE technology.
So long as your IP camera supports 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 installation, which greatly reduced the unit installation procedures, and get rid of the necessity of electric power cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum electricity rate is to 15.4 W of DC vitality (minimum 44V DC and 350mA) to each device.
In order to provide power for high power use devices, the IEEE connection made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of vitality.
PoE technology has been trusted in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Professional devices
#5. Negatives AND Advantages OF POE TECHNOLOGY
Let's firstly discuss the advantages of PoE. A PoE IP camera can get the energy from the Ethernet cable television, no need extra electricity cable or power supply.
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 disturbance, no sign jamming.
For properly working of PoE devices, Electricity 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 swap, which increased a little on cost.
#6. Wi-fi VS POE
No best solution, only right solution. If you want to install one single IP camera for home monitoring, you can opt for Wireless IP camera.
Making sure the Wireless IP camera is installed within coverage of your WiFi router.
For several IP camera, PoE is preferred. PoE is much reliable than WiFi in conditions of data transmitting.
Furthermore, an IP camera system predicated on PoE is a lot easier to take care of, centralized electricity solution becomes available e.g using uninterruptible power supply (UPS).
From my own investigation of monitoring market, I found that Wi-fi IP cameras are widely used for non-professional indoor home 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 wireless IP camera suits your needs?
Firstly, establish what you need. Many potential buyers often don't really know which kind of cellular IP camera suites and would fulfill their needs. Because of this, they get sucked into buying cordless IP camcorders that are beyond what they need.
Before clicking or picking on that item to buy, always consider: what conditions will the camera be located in? (Hallway, outdoor, low light or shiny); what perfection of data do you want to record? (HD images with or without audio tracks) & most importantly, what is your budget?
Second, another essential feature to consider before sometimes a wireless IP camera is the skillet and tilt range.
Obviously, this feature will be based upon the surroundings where you want to use the camera.
A wide skillet and tilt range is never a poor thing.
Thirdly, zooming capacity for the wireless IP camera is also vital.
Make sure that you check the kind of zooming capability, whether its optical or digital.
Most of the IP cameras on the market are digital, but you'll never fail to find one with optical focus.
Fourth, test the gear before purchase.
That is vital, particularly when you are buying from your local electronic store.
Always request for a test installation as this will permit you to determine the display quality of the camera.
Furthermore, it will give you an opportunity to learn how to set up the equipment in an effective manner to make certain you receive the best image and audio quality.
