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. While 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 complete IP camera system, you should analysis the unit installation environment and check out which functions you want to achieve.
WiFi or PoE, which is the foremost? As a senior technician that has four years in video monitoring industry, my answer to this question is PoE is the recommended choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology that allows network devices transfer data through cellular signal (2.4GHz UHF band, 5GHz SHF group).
Obviously, once the IP camera facilitates Wireless, the camera can hook up your router without using hardwired connection. WiFi can permit IP camera become portable, this is actually the advantage of Wi-fi.
But there are two drawbacks on WiFi, that happen to be; every electronic devices require power, which means your IP camera still requires cable connection for connection.
Up to now, I haven't found any IP cams are able to operate with batteries.
#3. HOW FAR Does indeed WI-FI REACH?
Limited WiFi transmission distance is another problem.
What lengths does indeed Wi-Fi reach? It's not easy to answer this question.
When discussing WiFi coverage, we've a lot of things to consider including electric power rate of Wi-fi device, environment (in house or outdoor) plus more.
Typically, a home/office router (TP-Link) can offer WiFi coverage grows to up to 10 meters interior.
When Wi-fi devices are working outdoor without hurdle, the transmission distance will be much considerably.
To increase the Wi-fi coverage or distance, you can mount WiFi gain access to point. Such an access point (or hotspot) has a range around 20 meters (66 toes) 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 was launched by Cisco in 1999. Transmitting both data and power over solo Ethernet cable (Feline5/6) is the primary feature of PoE technology.
So long as your IP camera supports PoE, you merely need to connect it to a PoE NVR or PoE switch, then it works. PoE technology permit IP camcorders support plug-and-play installation, which greatly reduced the installation procedures, and eliminate the necessity of electricity cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum ability rate is to 15.4 W of DC vitality (lowest 44V DC and 350mA) to each device.
In order to provide power supply for high ability intake devices, the IEEE connection made another new standard - IEEE802.3at, this standard also called PoE+ or PoE plus, provides up to 25.5 W of electric power.
PoE technology has been widely used in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Industrial devices
#5. Downsides AND Advantages OF POE TECHNOLOGY
Let's firstly discuss the advantages of PoE. A PoE IP camera can get the energy from the Ethernet wire, no need extra electric power cable or power.
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, Power 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 just 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 WiFi IP camera is installed within coverage of your Wireless router.
For several IP camera, PoE is recommended. PoE is a lot reliable than Wireless in terms of data transmission.
Furthermore, an IP camera system based on PoE is a lot easier to take care of, centralized ability solution becomes available e.g using uninterruptible power supply (UPS).
From my personal investigation of surveillance market, I came across that WiFi IP video cameras are widely used for non-professional indoor security, and PoE IP camcorders are installed for outdoor monitoring system. But if you select Wi-fi IP Camera please read article below.
So how would you determine which cellular IP camera suits your preferences?
Firstly, establish the thing you need. Many customers often don't really know which type of wireless IP camera suites and would fulfill their needs. As a result, they get sucked into buying wireless IP 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 glowing); what precision of data do you want to get? (HD images with or without audio tracks) & most importantly, what is your budget?
Second of all, another essential feature to consider before getting yourself a wireless IP camera is the skillet and tilt range.
Naturally, this feature will rely upon the surroundings where you want to use the camera.
A wide pan and tilt range is never a bad thing.
Thirdly, zooming capacity for the wireless IP camera is also essential.
Ensure that you check the sort of zooming capacity, whether its optical or digital.
A lot 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, especially when you are buying from your local digital store.
Always obtain a test set up as this will enable you to determine the picture quality of the camera.
Furthermore, it will give you an opportunity to learn how to create the equipment in a proper manner to make certain you obtain the best image and audio quality.
