WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. NO NEED TO USE BOTH Wi-fi AND PoE
Yes, you can't use both Wireless and PoE at same time. If you connect the IP camera to your router, you have to choose one of them, either Wireless or PoE.
Prior to deciding 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 attain.
Wi-fi or PoE, which is the greatest? As a mature technician who may have four years in video recording surveillance 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 transfer data through cellular indication (2.4GHz UHF strap, 5GHz SHF strap).
Obviously, after the IP camera facilitates WiFi, 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 disadvantages on WiFi, that happen to be; every gadgets require power, which means your IP camera still requires cable tv for connection.
So far, I haven't found any IP surveillance cameras have the ability to operate with battery power.
#3. WHAT LENGTHS Will WI-FI REACH?
Limited WiFi transmitting distance is another problem.
What lengths will Wi-Fi reach? It's not easy to answer this question.
When talking about WiFi coverage, we have a lot of things to consider including electricity rate of WiFi device, environment (indoor or outdoor) plus more.
Typically, a home/office router (TP-Link) provides WiFi coverage gets to up to 10 meters indoors.
When WiFi devices will work outdoor without hurdle, the transmitting distance will be much much.
To extend the WiFi coverage or distance, you can mount WiFi gain access to point. This gain access to point (or hotspot) has a variety around 20 meters (66 foot) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this isn't a new technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power supply over solo Ethernet cable tv (Pet cat5/6) is the main feature of PoE technology.
As long as your IP camera helps PoE, you just need to connect it to a PoE NVR or PoE switch, then it works. PoE technology permit IP camcorders support plug-and-play unit installation, which greatly reduced the set up 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 provides maximum ability rate is to 15.4 W of DC electric power (minimum amount 44V DC and 350mA) to each device.
To be able to provide power supply for high vitality 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 vitality.
PoE technology has been trusted in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Professional devices
#5. Downsides AND Positives OF POE TECHNOLOGY
Let's first of all discuss the advantages of PoE. A PoE IP camera can get the power 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 transmitting is through wired cable, there is no signal disturbance, no indication jamming.
For properly working of PoE devices, Electric power sourcing equipment (PSE) is vital component, it can be a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is much expensive than a traditional network switch, which increased just a little on cost.
#6. Wi-fi 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.
Ensuring the WiFi IP camera is installed within coverage of your WiFi router.
For more than one 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 deal with, centralized electric power solution becomes available e.g using uninterruptible power (UPS).
From my personal investigation of monitoring market, I found that Wi-fi IP video cameras are trusted for non-professional indoors security, and PoE IP video cameras are installed for outdoor security system. But if you choose Wi-fi IP Camera please read article below.
So how do you really determine which wireless IP camera suits your needs?
Firstly, establish what you need. Many buyers often don't really know which kind of cellular IP camera suites and would meet 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 ask yourself: what conditions will the camera be situated in? (Hallway, outdoor, low light or dazzling); what accuracy of data do you want to get? (HD images with or without music) and most importantly, what's your budget?
Subsequently, another essential feature to consider before sometimes a wireless IP camera is the skillet and tilt range.
Needless to say, this feature will be based upon the environment where you intend to use the camera.
A broad pan and tilt range is never a bad thing.
Thirdly, zooming capacity for the cordless IP camera is also essential.
Ensure that you check the kind 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 zoom.
Fourth, test the gear before purchase.
This is vital, specially when you are buying from your neighborhood electronic 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 chance to learn how to set up the gear in an effective manner to make sure that you get the best image and sound quality.
