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. When you connect 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 whole IP camera system, you should analysis the installation environment and research which functions you want to achieve.
WiFi or PoE, which is the best? As a older technician that has four years in training video security industry, my answer to this question is PoE is the suggested choice.
#2. WHAT'S WIFI
WiFi is some sort of wireless technology which allows network devices transmit data through cellular signal (2.4GHz UHF group, 5GHz SHF strap).
Obviously, once the IP camera facilitates Wireless, the camera can connect your router without using hardwired connection. WiFi can enable IP camera become lightweight, this is actually the advantage of Wireless.
But there are two drawbacks on WiFi, that are; every electronic devices require power supply, that means your IP camera still requires cable television for connection.
Up to now, I haven't found any IP surveillance cameras have the ability to operate with battery power.
#3. WHAT LENGTHS DOES WI-FI REACH?
Limited WiFi transmission distance is another problem.
What lengths does indeed Wi-Fi reach? It isn't easy to answer this question.
When discussing WiFi coverage, we have many things to consider including vitality rate of WiFi device, environment (indoors or outdoor) and even more.
Typically, a home/office router (TP-Link) provides WiFi coverage reaches up to 10 meters indoors.
When Wi-fi devices will work outdoor without barrier, the transmitting distance will be much much.
To extend the Wireless coverage or distance, you can set up WiFi gain access to point. This gain access to point (or hotspot) has a variety around 20 meters (66 feet) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE stands for Power over Ethernet, this is not a fresh technology, the first device adopts PoE technology was launched by Cisco in 1999. Transmitting both data and power over sole Ethernet cable tv (Pet cat5/6) is the key feature of PoE technology.
So long as your IP camera facilitates PoE, you merely need to connect it to a PoE NVR or PoE switch, then it works. PoE technology enable IP camcorders support plug-and-play assembly, which greatly reduced the set up procedures, and eliminate the necessity of electric power 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 (minimal 44V DC and 350mA) to each device.
To be able to provide power supply for high power usage devices, the IEEE relationship 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 surveillance system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Professional devices
#5. Drawbacks AND Positives OF POE TECHNOLOGY
Let's first of all discuss the benefits of PoE. A PoE IP camera can get the power from the Ethernet cable tv, no need extra ability cable or power.
The maximum interconnection distance is 100 meters, which is ten times than Wireless. Since data transmitting is through wired wire, there is no signal disturbance, no sign jamming.
For properly working of PoE devices, Ability 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 move, which increased just a little on cost.
#6. Wireless VS POE
No best solution, only right solution. If you wish to install a unitary IP camera for home monitoring, you can opt for Wireless IP camera.
Making sure the Wi-fi IP camera is installed within coverage of your Wireless router.
For more than one IP camera, PoE is preferred. PoE is much reliable than Wireless in conditions of data transmission.
Furthermore, an IP camera system predicated on PoE is a lot easier to deal with, centralized ability solution becomes available e.g using uninterruptible power (UPS).
From my personal investigation of security market, I came across that WiFi IP surveillance cameras are widely used for non-professional inside security, and PoE IP cams are installed for outdoor security system. But if you select Wireless IP Camera please read article below.
So how can you determine which cellular IP camera suits your preferences?
Firstly, establish what you need. Many clients often don't really know which kind of cordless 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 detail of data would you like to get? (HD images with or without audio) & most importantly, what is your budget?
Second, another essential feature to consider before sometimes a radio IP camera is the pan and tilt range.
Of course, this feature will depend on the environment where you would like to use the camera.
A broad pan and tilt range is never an awful thing.
Thirdly, zooming capacity for the wireless IP camera is also essential.
Make sure that you check the sort of zooming capability, whether its optical or digital.
A lot of the IP cameras in the market are digital, but you'll never fail to find one with optical move.
Fourth, test the gear before purchase.
This is vital, specially when you are buying from your neighborhood electronic digital store.
Always obtain a test setup as this will enable you to determine the display quality of the camera.
In addition, it will offer you an chance to learn how to create the equipment in a proper manner to make sure that you have the best image and audio quality.
