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 WiFi and PoE at same time. Whenever you hook up the IP camera to your router, you have to choose one of these, either WiFi or PoE.
Prior to deciding to buy an IP camera or a complete IP camera system, you should analysis the assembly environment and research which functions you want to accomplish.
Wireless or PoE, which is best? As a older technician who may have four years in video recording surveillance industry, my response to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology that allows network devices transfer data through wireless transmission (2.4GHz UHF music group, 5GHz SHF music group).
Obviously, once the IP camera supports WiFi, the camera can connect your router without needing hardwired connection. WiFi can enable IP camera become lightweight, this is actually the advantage of Wi-fi.
But there are two drawbacks on WiFi, that happen to be; every electronic devices require power supply, which means your IP camera still requires cable connection for connection.
So far, I haven't found any IP video cameras have the ability to operate with power packs.
#3. WHAT LENGTHS DOES WI-FI REACH?
Limited WiFi transmission distance is another problem.
How far will Wi-Fi reach? It's not easy to answer this question.
When discussing WiFi coverage, we've a lot of things to consider including power rate of Wi-fi device, environment (interior or outdoor) and much more.
Typically, a home/office router (TP-Link) provides WiFi coverage extends to up to 10 meters inside.
When Wi-fi devices are working outdoor without barrier, the transmission distance will be much way.
To increase the WiFi coverage or distance, you can mount WiFi access point. This gain access to point (or hotspot) has a range of about 20 meters (66 legs) indoors and a greater 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 supply over solo Ethernet wire (Feline5/6) is the primary feature of PoE technology.
As 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 enable IP surveillance cameras support plug-and-play installation, which greatly reduced the assembly procedures, and eliminate the necessity of vitality cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum electricity rate is to 15.4 W of DC power (minimal 44V DC and 350mA) to each device.
In order to provide power supply for high power intake 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 vitality.
PoE technology has been trusted in:
- IP surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Access Point
- Network Routers
- Commercial devices
#5. CONS AND Positives OF POE TECHNOLOGY
Let's firstly discuss the features of PoE. A PoE IP camera can get the power from the Ethernet cable television, no need extra electricity cable or power.
The maximum interconnection distance is 100 meters, which is ten times than Wireless. Since data transmission is through wired cable connection, there is no signal disturbance, no transmission jamming.
For properly working of PoE devices, Vitality sourcing equipment (PSE) is essential component, it's rather a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is much expensive than a traditional network transition, which increased just a little on cost.
#6. Wireless VS POE
No best answer, only right solution. If you wish to install one single IP camera for home monitoring, you can opt for Wi-fi IP camera.
Guaranteeing the Wi-fi IP camera is installed within coverage of your WiFi router.
For more than one IP camera, PoE is preferred. PoE is a lot reliable than Wireless in terms of data transmitting.
Furthermore, an IP camera system predicated on PoE is much easier to take care of, centralized vitality solution becomes available e.g using uninterruptible power supply (UPS).
From my own investigation of surveillance market, I found that Wireless IP cameras are widely used for non-professional interior security, and PoE IP cams are installed for outdoor security system. But if you select WiFi IP Camera please read article below.
So how would you determine which cordless IP camera suits your needs?
Firstly, establish the thing 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 wireless IP cams that are beyond what they want.
Before clicking or picking on that item to buy, always consider: what conditions will the camera be situated in? (Hallway, outdoor, low light or excellent); what precision of data would you like to catch? (HD images with or without audio) and most importantly, what is your budget?
Subsequently, another essential feature to consider before sometimes a radio IP camera is the skillet and tilt range.
Certainly, this feature will depend on the environment where you intend to use the camera.
A wide pan and tilt range is never an awful thing.
Thirdly, zooming capacity for the wireless 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 on the market are digital, but you'll never neglect to find one with optical zoom.
Fourth, test the equipment before purchase.
That is vital, specially when you are buying from your local digital store.
Always obtain a test set up as this will enable you to look for the display quality of the camera.
Furthermore, it will offer you an opportunity to learn how to set up the equipment in a proper manner to make sure that you receive the best image and sound quality.
