WIFI OR PoE FOR IP CAMERA, WHICH IS THE BEST?
#1. YOU DON'T NEED TO USE BOTH Wireless AND PoE
Yes, you can't use both Wi-fi and PoE at same time. After you hook up the IP camera to your router, you have to choose one of them, either WiFi or PoE.
Before you decide to buy an IP camera or a whole IP camera system, you should analysis the assembly environment and check out which functions you want to accomplish.
Wireless or PoE, which is the greatest? As a mature technician who may have four years in training 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 which allows network devices transfer data through wireless signal (2.4GHz UHF band, 5GHz SHF group).
Obviously, after the IP camera helps Wi-fi, the camera can connect your router without needing hardwired connection. Wi-fi can enable IP camera become lightweight, this is actually the advantage of Wi-fi.
But there are two disadvantages on WiFi, that are; every electronic devices require power supply, that means your IP camera still requires cable connection for connection.
So far, I haven't found any IP camcorders have the ability to operate with power packs.
#3. WHAT LENGTHS DOES WI-FI REACH?
Limited WiFi transmitting distance is another problem.
What lengths will Wi-Fi reach? It isn't easy to answer this question.
When discussing WiFi coverage, we have a lot of things to consider including electricity rate of WiFi device, environment (inside or outdoor) plus more.
Typically, a home/office router (TP-Link) provides WiFi coverage extends to up to 10 meters interior.
When Wi-fi devices will work outdoor without hurdle, the transmission distance will be much very good.
To increase the WiFi coverage or distance, you can mount WiFi gain access to point. Such an access point (or hotspot) has a variety of about 20 meters (66 ft) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE stands for 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 supply over single Ethernet cable (Cat5/6) is the main feature of PoE technology.
So long as your IP camera helps PoE, you merely need to connect it to a PoE NVR or PoE switch, then it works. PoE technology enable IP cameras support plug-and-play installation, which greatly reduced the unit installation procedures, and get rid of the necessity of ability cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum electric power rate is to 15.4 W of DC electricity (minimal 44V DC and 350mA) to each device.
In order to provide power for high ability utilization devices, the IEEE association made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of electric power.
PoE technology has been trusted in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Professional devices
#5. Negative aspects 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 tv, no need extra electric power cable or power.
The maximum connection distance is 100 meters, which is ten times than Wi-fi. Since data transmission is through wired wire, there is absolutely no signal disturbance, no transmission 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 a little on cost.
#6. Wireless VS POE
No best answer, 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 WiFi IP camera is installed within coverage of your Wireless router.
For several IP camera, PoE is recommended. PoE is much reliable than Wi-fi in conditions of data transmitting.
Furthermore, an IP camera system based on PoE is a lot easier to control, centralized power solution becomes available e.g using uninterruptible power (UPS).
From my personal investigation of security market, I found that WiFi IP cameras are widely used for non-professional indoor home security, and PoE IP video cameras are installed for outdoor monitoring system. But if you choose Wi-fi IP Camera please read article below.
So how will you determine which wireless IP camera suits your needs?
Firstly, establish what you need. Many potential buyers often don't really know which type of wireless IP camera suites and would satisfy 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 glowing); what perfection of data do you want to catch? (HD images with or without music) & most importantly, what's your budget?
Second, another essential feature to consider before sometimes a radio IP camera is the pan and tilt range.
Obviously, this feature will depend on the environment where you would like to use the camera.
A broad pan and tilt range is never an undesirable thing.
Thirdly, zooming capability of the cordless IP camera is also vital.
Ensure that you check the type of zooming capabilities, whether its optical or digital.
Most 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, particularly when you are buying from your local electronic digital store.
Always request for a test installation as this will enable you to look for the display quality of the camera.
In addition, it will give you an chance to learn how to create the equipment in a proper manner to ensure that you get the best image and audio quality.
