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. Once you hook up the IP camera to your router, you have to choose one of these, either WiFi or PoE.
Before you decide to buy an IP camera or a complete IP camera system, you should analysis the set up environment and research which functions you want to accomplish.
WiFi or PoE, which is the greatest? As a mature technician who have four years in video monitoring industry, my answer 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 indication (2.4GHz UHF strap, 5GHz SHF music group).
Obviously, once the IP camera facilitates WiFi, the camera can connect your router without needing hardwired connection. Wi-fi can permit IP camera become lightweight, this is the advantage of WiFi.
But there are two downsides on WiFi, which can be; every electronic devices require power, that means your IP camera still requires cable television for connection.
So far, I haven't found any IP video cameras are able to operate with power packs.
#3. HOW FAR Does indeed WI-FI REACH?
Limited WiFi transmission distance is another problem.
What lengths will Wi-Fi reach? It isn't easy to answer this question.
When talking about WiFi coverage, we have a lot of things to consider including power rate of Wi-fi device, environment (inside or outdoor) and more.
Typically, a home/office router (TP-Link) can provide WiFi coverage reaches up to 10 meters indoor.
When Wi-fi devices will work outdoor without barrier, the transmitting distance will be much far.
To increase the WiFi coverage or distance, you can set up WiFi gain access to point. Such an access point (or hotspot) has a variety around 20 meters (66 ft) indoors and a larger range outdoors.
#4. WHAT'S POE?
PoE means Power over Ethernet, this isn't a fresh technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power supply over solo Ethernet cable (Pet cat5/6) is the main feature of PoE technology.
As long as your IP camera facilitates PoE, you just need to hook up it to a PoE NVR or PoE switch, then it works. PoE technology enable IP cameras support plug-and-play set up, which greatly reduced the assembly procedures, and eliminate the necessity of electric power cable and supply.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum ability rate is to 15.4 W of DC vitality (minimal 44V DC and 350mA) to each device.
To be able to provide power for high ability use devices, the IEEE relationship made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of power.
PoE technology has been widely used in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Commercial devices
#5. Drawbacks AND Positives 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 vitality cable or power.
The maximum interconnection distance is 100 meters, which is ten times than Wireless. Since data transmitting is through wired cable, there is absolutely no signal disturbance, no indication jamming.
For properly working of PoE devices, Electric power sourcing equipment (PSE) is essential component, it can be a network PoE switch, or an intermediary device such as PoE injector.
A PoE switch is much expensive when compared to a traditional network swap, which increased just a little on cost.
#6. Wireless VS POE
No best answer, only right solution. If you wish to install a unitary IP camera for home monitoring, you can choose to use Wi-fi IP camera.
Making sure the Wireless IP camera is installed within coverage of your Wireless router.
For several IP camera, PoE is recommended. PoE is a lot reliable than Wireless in conditions of data transmission.
Furthermore, an IP camera system based on PoE is much easier to manage, centralized vitality solution becomes available e.g using uninterruptible power supply (UPS).
From my own investigation of surveillance market, I found that Wireless IP video cameras are widely used for non-professional inside home security, and PoE IP video cameras are installed for outdoor surveillance system. But if you select Wireless IP Camera please read article below.
So how will you determine which cellular IP camera suits your preferences?
Firstly, establish what you need. Many purchasers often don't really know which kind of wireless IP camera suites and would satisfy their needs. As a result, they get sucked into buying cordless IP cams 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 shiny); what accuracy of data would you like to capture? (HD images with or without audio tracks) & 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.
Certainly, this feature will rely upon the environment where you intend to use the camera.
A wide skillet and tilt range is never a poor thing.
Thirdly, zooming capacity for the cordless IP camera is also essential.
Ensure that you check the type 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 move.
Fourth, test the equipment before purchase.
This is vital, in particular when you are buying from your neighborhood electronic digital store.
Always obtain a test installation 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 create the equipment in an effective manner to make certain you find the best image and sound quality.
