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 Wireless and PoE at same time. When you connect the IP camera to your router, you have to choose one of them, either Wi-fi or PoE.
Before you decide to buy an IP camera or a complete IP camera system, you should analysis the set up environment and check out which functions you want to achieve.
Wireless 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 recommended choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology which allows network devices transmit data through cellular signal (2.4GHz UHF strap, 5GHz SHF music group).
Obviously, after the IP camera facilitates Wireless, the camera can connect your router without using hardwired connection. Wi-fi can enable IP camera become portable, this is the advantage of Wireless.
But there are two drawbacks on WiFi, that are; every gadgets require power supply, which means your IP camera still requires cable for connection.
So far, I haven't found any IP cameras have the ability to operate with battery 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 discussing WiFi coverage, we have many things to consider including power rate of Wireless device, environment (in house or outdoor) and even more.
Typically, a home/office router (TP-Link) can provide WiFi coverage reaches up to 10 meters inside.
When WiFi devices will work outdoor without barrier, the transmission distance will be much significantly.
To extend the WiFi coverage or distance, you can set up WiFi access point. Such an access point (or hotspot) has a range around 20 meters (66 ft) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this is not a new technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power supply over sole Ethernet cable (Pet cat5/6) is the key feature of PoE technology.
So long as your IP camera facilitates PoE, you just need to connect it to a PoE NVR or PoE switch, then it works. PoE technology permit IP cameras support plug-and-play installation, which greatly reduced the set up procedures, and eliminate the necessity of electricity cable and supply.
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 (least 44V DC and 350mA) to each device.
In order to provide power for high power ingestion devices, the IEEE relationship made another new standard - IEEE802.3at, this standard also called PoE+ or PoE plus, provides up to 25.5 W of ability.
PoE technology has been widely used in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Commercial 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 wire, no need extra ability cable or power.
The maximum connection distance is 100 meters, which is ten times than Wireless. Since data transmitting is through wired cable tv, there is no signal disturbance, no sign 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 when compared to a traditional network move, which increased just a little on cost.
#6. WIFI VS POE
No best answer, only right solution. If you want to install a unitary IP camera for home monitoring, you can opt for WiFi IP camera.
Ensuring the Wireless IP camera is installed within coverage of your Wi-fi router.
For several IP camera, PoE is recommended. PoE is much reliable than Wireless in terms of data transmitting.
Furthermore, an IP camera system based on PoE is much easier to deal with, centralized electric power solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of security market, I found that Wi-fi IP camcorders are widely used for non-professional inside security, and PoE IP surveillance cameras are installed for outdoor monitoring system. But if you select Wi-fi IP Camera please read article below.
So how will you determine which cellular IP camera suits your preferences?
Firstly, establish the thing you need. Many customers 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 ask yourself: what conditions will the camera be located in? (Hallway, outdoor, low light or excellent); what accuracy of data would you like to record? (HD images with or without audio) & most importantly, what's your budget?
Second of all, another essential feature to consider before getting yourself a wireless IP camera is the pan and tilt range.
Certainly, this feature will depend on the surroundings where you would like to use the camera.
A broad pan and tilt range is never an awful thing.
Thirdly, zooming capability of the cordless IP camera is also essential.
Make sure that you check the type of zooming capability, whether its optical or digital.
A lot of the IP cameras in the market are digital, but you will never fail to find one with optical focus.
Fourth, test the equipment before purchase.
This is vital, particularly when you are buying from your local digital store.
Always obtain a test installation as this will enable you to look for the display quality of the camera.
Furthermore, it will offer you an chance to learn how to create the equipment in a proper manner to make certain you find the best image and audio tracks quality.
