WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. NO NEED TO USE BOTH Wireless AND PoE
Yes, you can't use both WiFi and PoE at same time. When you hook up the IP camera to your router, you have to choose one of them, either Wireless or PoE.
Before you decide to buy an IP camera or a whole IP camera system, you should analysis the installation environment and research which functions you want to attain.
WiFi or PoE, which is best? As a mature technician who have four years in video monitoring industry, my response 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 wireless signal (2.4GHz UHF group, 5GHz SHF group).
Obviously, after the IP camera facilitates Wireless, the camera can hook up your router without using hardwired connection. Wireless can enable IP camera become lightweight, this is actually the advantage of Wireless.
But there are two disadvantages on WiFi, which are; every electronic devices require power, which means your IP camera still requires cable tv for connection.
Up to now, I haven't found any IP cameras have the ability to operate with batteries.
#3. HOW FAR Does indeed WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far does indeed Wi-Fi reach? It's not easy to answer this question.
When discussing WiFi coverage, we've many things to consider including power rate of WiFi 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 Wireless devices will work outdoor without barrier, the transmitting distance will be much considerably.
To extend the Wireless coverage or distance, you can install WiFi gain access to point. Such an access point (or hotspot) has a range of about 20 meters (66 legs) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this is not a fresh technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power over solitary Ethernet cable (Cat5/6) is the main feature of PoE technology.
As long as your IP camera supports PoE, you just need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology enable IP cameras support plug-and-play assembly, which greatly reduced the assembly procedures, and get rid of the necessity of electricity cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can offer maximum electricity rate is to 15.4 W of DC power (lowest 44V DC and 350mA) to each device.
In order to provide power supply for high power intake 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 power.
PoE technology has been widely used in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Professional devices
#5. Downsides AND Benefits OF POE TECHNOLOGY
Let's firstly discuss the advantages of PoE. A PoE IP camera can get the power from the Ethernet wire, no need extra ability cable or power supply.
The maximum connection distance is 100 meters, which is ten times than WiFi. Since data transmission is through wired cable television, there is absolutely no signal disturbance, no transmission jamming.
For properly working of PoE devices, Ability 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. Wireless VS POE
No best answer, only right solution. If you want to install a unitary IP camera for home monitoring, you can opt for Wireless IP camera.
Making sure the Wi-fi IP camera is installed within coverage of your WiFi router.
For more than one IP camera, PoE is recommended. PoE is much reliable than Wireless 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 supply (UPS).
From my own investigation of security market, I found that WiFi IP cams are trusted for non-professional indoor home security, and PoE IP cameras are installed for outdoor security system. But if you select WiFi IP Camera please read article below.
So how will you determine which wireless IP camera suits your preferences?
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 cellular IP video cameras 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 precision of data do you want to record? (HD images with or without sound) and most importantly, what is your budget?
Subsequently, another essential feature to consider before getting yourself a wireless IP camera is the skillet and tilt range.
Of course, this feature will be based upon the surroundings where you intend to use the camera.
A wide pan and tilt range is never an undesirable thing.
Thirdly, zooming capacity for the wireless IP camera is also vital.
Make sure that you check the kind of zooming functionality, whether its optical or digital.
Most of the IP cameras in the market are digital, but you'll never fail to find one with optical focus.
Fourth, test the equipment before purchase.
This is vital, specially when you are buying from your local electronic store.
Always request for a test set up as this will allow you to look for the display quality of the camera.
In addition, it will give you an opportunity to learn how to set up the equipment in a proper manner to make certain you find the best image and audio quality.
