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 WiFi and PoE at same time. While you connect the IP camera to your router, you have to choose one of these, 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.
WiFi or PoE, which is the best? As a senior technician who may have four years in video recording monitoring industry, my answer to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology which allows network devices transmit data through cordless transmission (2.4GHz UHF group, 5GHz SHF strap).
Obviously, after the IP camera facilitates Wi-fi, the camera can hook up your router without needing hardwired connection. Wi-fi can enable IP camera become portable, this is the advantage of Wi-fi.
But there are two downsides on WiFi, which are; every electronic devices require power, that means your IP camera still requires cable television for connection.
Up to now, I haven't found any IP cameras are able to operate with battery packs.
#3. WHAT LENGTHS DOES WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far will Wi-Fi reach? It's not easy to answer this question.
When discussing WiFi coverage, we have many things to consider including power rate of Wireless device, environment (interior or outdoor) plus more.
Typically, a home/office router (TP-Link) can offer WiFi coverage gets to up to 10 meters interior.
When Wi-fi devices are working outdoor without hurdle, the transmission distance will be much considerably.
To extend the Wi-fi coverage or distance, you can install WiFi gain access to point. This access point (or hotspot) has a range of about 20 meters (66 ft) 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 premiered by Cisco in 1999. Transmitting both data and power over solitary Ethernet cable (Kitty5/6) is the key feature of PoE technology.
So long as your IP camera facilitates PoE, you merely need to connect it to a PoE NVR or PoE switch, then it works. PoE technology allow IP video cameras support plug-and-play set up, which greatly reduced the unit installation procedures, and get rid of the necessity of ability cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can offer maximum electric power rate is to 15.4 W of DC vitality (minimum 44V DC and 350mA) to each device.
In order to provide power supply for high power ingestion 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 electricity.
PoE technology has been trusted in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Professional devices
#5. Downsides AND Advantages OF POE TECHNOLOGY
Let's firstly discuss the benefits of PoE. A PoE IP camera can get the power from the Ethernet cable, no need extra power cable or power supply.
The maximum interconnection distance is 100 meters, which is ten times than Wireless. Since data transmitting is through wired cable, there is absolutely no signal disturbance, 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 transition, which increased a little on cost.
#6. Wi-fi VS POE
No best answer, only right solution. If you want to install one single IP camera for home monitoring, you can opt for Wi-fi IP camera.
Ensuring the Wi-fi IP camera is installed within coverage of your Wi-fi router.
For several IP camera, PoE is preferred. PoE is much reliable than Wi-fi in conditions of data transmitting.
Furthermore, an IP camera system based on PoE is a lot easier to take care of, centralized electricity solution becomes available e.g using uninterruptible power (UPS).
From my personal investigation of monitoring market, I came across that Wireless IP cameras are widely used for non-professional indoors security, and PoE IP video cameras are installed for outdoor surveillance system. But if you select Wireless IP Camera please read article below.
So how will you determine which cellular IP camera suits your needs?
Firstly, establish what you need. Many buyers often don't really know which type of cellular IP camera suites and would fulfill their needs. As a result, they get sucked into buying wireless IP surveillance cameras that are beyond what they want.
Before clicking or picking on that item to buy, always consider: what conditions will the camera be situated in? (Hallway, outdoor, low light or bright); what detail of data do you want to take? (HD images with or without audio tracks) & most importantly, what is your budget?
Second of all, another essential feature to consider before sometimes a radio IP camera is the skillet and tilt range.
Obviously, this feature will rely upon the surroundings where you intend to use the camera.
A wide skillet and tilt range is never a poor thing.
Thirdly, zooming capability of the wireless IP camera is also essential.
Make sure that you check the type 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 zoom.
Fourth, test the gear before purchase.
This is vital, particularly when you are buying from your local electric store.
Always request for a test set up as this will allow you to look for the display quality of the camera.
Furthermore, it will give you an possibility to learn how to set up the gear in a proper manner to make sure that you get the best image and audio tracks quality.
