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 Wi-fi and PoE at same time. Whenever 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 complete IP camera system, you should analysis the unit installation environment and check out which functions you want to attain.
Wi-fi or PoE, which is a good? As a older technician who have four years in video monitoring industry, my response to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology which allows network devices transmit data through cordless indication (2.4GHz UHF group, 5GHz SHF strap).
Obviously, once the IP camera supports Wi-fi, the camera can hook up your router without needing hardwired connection. Wi-fi can permit IP camera become lightweight, this is actually the advantage of Wireless.
But there are two disadvantages on WiFi, that happen to be; every electronic devices require power, that means your IP camera still requires cable connection for connection.
Up to now, I haven't found any IP cameras have the ability to operate with electric batteries.
#3. HOW FAR DOES WI-FI REACH?
Limited WiFi transmitting distance is another problem.
What lengths does indeed Wi-Fi reach? It isn't easy to answer this question.
When discussing WiFi coverage, we've many things to consider including power rate of WiFi device, environment (indoor or outdoor) and much more.
Typically, a home/office router (TP-Link) can offer WiFi coverage gets to up to 10 meters in house.
When Wireless devices will work outdoor without barrier, the transmission distance will be much far.
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 variety of about 20 meters (66 ft) indoors and a greater 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 single Ethernet cable television (Feline5/6) is the primary feature of PoE technology.
So long as your IP camera supports PoE, you just need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology permit IP camcorders support plug-and-play set up, which greatly reduced the assembly procedures, and get rid of the necessity of power cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af can provide maximum power rate is to 15.4 W of DC electric power (minimal 44V DC and 350mA) to each device.
In order to provide power for high vitality usage devices, the IEEE association made another new standard - IEEE802.3at, this standard also called PoE+ or PoE plus, provides up to 25.5 W of power.
PoE technology has been widely used in:
- IP monitoring system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Professional devices
#5. Disadvantages AND PROS OF POE TECHNOLOGY
Let's first of all discuss the features of PoE. A PoE IP camera can get the power from the Ethernet cable connection, no need extra power cable or power.
The maximum connection distance is 100 meters, which is ten times than WiFi. Since data transmission is through wired cable tv, there is absolutely no signal interference, no sign jamming.
For properly working of PoE devices, Electric 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 when compared to a traditional network change, 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 opt for Wi-fi IP camera.
Making sure the WiFi IP camera is installed within coverage of your Wireless router.
For more than one IP camera, PoE is recommended. PoE is a lot reliable than Wireless in terms of data transmitting.
Furthermore, an IP camera system predicated on PoE is a lot easier to take care of, centralized power solution becomes available e.g using uninterruptible power (UPS).
From my own investigation of security market, I came across that Wireless IP video cameras are widely used for non-professional interior security, and PoE IP camcorders are installed for outdoor monitoring system. But if you choose WiFi IP Camera please read article below.
So how can you determine which cordless IP camera suits your needs?
Firstly, establish what you need. Many customers often don't really know which type of wireless IP camera suites and would meet their needs. As a result, they get sucked into buying wireless IP surveillance 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 located in? (Hallway, outdoor, low light or bright); what precision of data do you want to get? (HD images with or without sound) and most importantly, what is your budget?
Second of all, another essential feature to consider before sometimes a wireless IP camera is the skillet and tilt range.
Naturally, this feature will depend on the surroundings where you want to use the camera.
A wide pan and tilt range is never a poor thing.
Thirdly, zooming capacity for the wireless IP camera is also vital.
Make sure that you check the kind of zooming potential, whether its optical or digital.
A lot of the IP cameras on the market are digital, but you'll never neglect 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 obtain a test setup as this will enable you to look for the picture quality of the camera.
In addition, it will give you an possibility to learn how to set up the gear in a proper manner to make certain you get the best image and audio quality.
