WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. NO NEED TO USE BOTH WIFI AND PoE
Yes, you can't use both WiFi and PoE at same time. When you connect the IP camera to your router, you have to choose one of these, either Wi-fi or PoE.
Before you decide to buy an IP camera or a whole IP camera system, you should analysis the set up environment and research which functions you want to attain.
Wireless or PoE, which is the better? As a mature technician who may have four years in video monitoring 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 transmit data through cordless indication (2.4GHz UHF music group, 5GHz SHF group).
Obviously, once the IP camera helps WiFi, the camera can hook up your router without needing hardwired connection. WiFi can permit IP camera become portable, this is the advantage of Wi-fi.
But there are two disadvantages on WiFi, which can be; every electronic devices require power supply, which means your IP camera still requires cable tv for connection.
So far, I haven't found any IP camcorders have the ability to operate with battery power.
#3. WHAT LENGTHS DOES WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far does Wi-Fi reach? It isn't easy to answer this question.
When discussing WiFi coverage, we've many things to consider including electricity rate of Wireless device, environment (in house or outdoor) and more.
Typically, a home/office router (TP-Link) can offer WiFi coverage extends to up to 10 meters inside.
When Wireless devices are working outdoor without barrier, the transmission distance will be much considerably.
To increase the Wi-fi coverage or distance, you can set up WiFi gain access to point. Such an gain access to point (or hotspot) has a range around 20 meters (66 feet) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this isn't a fresh technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power supply over solo Ethernet cable television (Cat5/6) is the key 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 unit installation, which greatly reduced the set up procedures, and get rid of the necessity of 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 electric power (least 44V DC and 350mA) to each device.
To be able to provide power for high electric 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 electricity.
PoE technology has been trusted in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Commercial devices
#5. Drawbacks AND PROS 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 connection, no need extra electric power cable or power supply.
The maximum connection distance is 100 meters, which is ten times than Wireless. 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 much expensive when compared to a traditional network swap, which increased just a little on cost.
#6. Wireless VS POE
No best solution, only right solution. If you want to install one single IP camera for home monitoring, you can choose to use WiFi IP camera.
Guaranteeing the Wireless IP camera is installed within coverage of your Wi-fi router.
For several IP camera, PoE is preferred. PoE is a lot reliable than Wi-fi in conditions of data transmission.
Furthermore, an IP camera system predicated on PoE is a lot easier to control, centralized vitality solution becomes available e.g using uninterruptible power supply (UPS).
From my own investigation of monitoring market, I found that WiFi IP cams are trusted for non-professional in house security, and PoE IP video cameras are installed for outdoor monitoring system. But if you choose WiFi IP Camera please read article below.
So how does one determine which cellular IP camera suits your needs?
Firstly, establish what you need. Many clients often don't really know which type of wireless IP camera suites and would satisfy their needs. Because of this, they get sucked into buying cellular 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 smart); what accuracy of data do you want to get? (HD images with or without audio tracks) & most importantly, what's your budget?
Second of all, another essential feature to consider before getting yourself a radio IP camera is the skillet and tilt range.
Of course, this feature will rely upon the environment where you intend to use the camera.
A broad skillet and tilt range is never a poor thing.
Thirdly, zooming capability of the wireless IP camera is also vital.
Ensure that you check the sort of zooming functionality, whether its optical or digital.
A lot of the IP cameras in the market are digital, but you'll never fail to find one with optical move.
Fourth, test the gear before purchase.
That is vital, particularly when you are buying from your neighborhood electric store.
Always request for a test installation as this will enable you to look for the picture quality of the camera.
Furthermore, it will offer you an opportunity to learn how to set up the gear in a proper manner to make certain you receive the best image and music quality.
