WIFI OR PoE FOR IP CAMERA, WHICH MAY BE THE BEST?
#1. NO NEED TO USE BOTH Wi-fi 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 these, either Wireless or PoE.
Before you decide to buy an IP camera or a whole IP camera system, you should analysis the assembly environment and research which functions you want to accomplish.
Wireless or PoE, which is the better? As a older technician that has four years in video tutorial monitoring industry, my answer to this question is PoE is the advised choice.
#2. WHAT'S WIFI
WiFi is a kind of wireless technology that allows network devices transmit data through cordless transmission (2.4GHz UHF band, 5GHz SHF strap).
Obviously, once the IP camera helps Wireless, the camera can hook up your router without needing hardwired connection. Wi-fi can enable IP camera become portable, this is the advantage of Wi-fi.
But there are two drawbacks on WiFi, which can be; every electronic devices require power supply, that means your IP camera still requires cable tv for connection.
Up to now, I haven't found any IP video cameras are able to operate with battery packs.
#3. WHAT LENGTHS Does indeed 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 talking about WiFi coverage, we've a lot of things to consider including electricity rate of Wi-fi device, environment (interior or outdoor) and even more.
Typically, a home/office router (TP-Link) can offer WiFi coverage extends to up to 10 meters indoor.
When Wireless devices will work outdoor without hurdle, the transmission distance will be much much.
To increase the Wi-fi coverage or distance, you can mount WiFi access point. This access point (or hotspot) has a range around 20 meters (66 foot) indoors and a greater range outdoors.
#4. WHAT'S POE?
PoE stands for Power over Ethernet, this isn't a new technology, the first device adopts PoE technology premiered by Cisco in 1999. Transmitting both data and power supply over solo Ethernet wire (Kitty5/6) is the key feature of PoE technology.
So long as your IP camera supports PoE, you merely need to connect it to a PoE NVR or PoE switch, then it works. PoE technology permit IP camcorders support plug-and-play installation, which greatly reduced the set up procedures, and get rid of the necessity of power cable and offer.
Today, PoE has two standard including IEEE802.3af, and IEEE802.3at. IEEE802.3af provides maximum power rate is to 15.4 W of DC power (minimum amount 44V DC and 350mA) to each device.
In order to provide power for high vitality intake devices, the IEEE connection made another new standard - IEEE802.3at, this standard also known as PoE+ or PoE plus, provides up to 25.5 W of ability.
PoE technology has been widely used in:
- IP security system ( Camera + NVR)
- VoIP Phones
- WiFi Gain access to Point
- Network Routers
- Professional devices
#5. CONS AND Advantages OF POE TECHNOLOGY
Let's first of all discuss the benefits of PoE. A PoE IP camera can get the energy from the Ethernet wire, no need extra ability cable or power.
The maximum interconnection distance is 100 meters, which is ten times than Wi-fi. Since data transmitting is through wired cable television, there is absolutely no signal disturbance, no sign jamming.
For properly working of PoE devices, Electric power 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 switch, which increased a little on cost.
#6. Wireless VS POE
No best solution, only right solution. If you want to install a unitary IP camera for home monitoring, you can choose to use Wireless IP camera.
Guaranteeing the WiFi IP camera is installed within coverage of your WiFi router.
For several IP camera, PoE is recommended. PoE is a lot reliable than Wireless in conditions of data transmitting.
Furthermore, an IP camera system based on PoE is much easier to control, centralized vitality solution becomes available e.g using uninterruptible power (UPS).
From my personal investigation of monitoring market, I found that Wireless IP surveillance cameras are widely used for non-professional interior home security, and PoE IP surveillance cameras are installed for outdoor surveillance system. But if you select Wireless IP Camera please read article below.
So how would you determine which wireless IP camera suits your needs?
Firstly, establish what you need. Many customers often don't really know which type of cordless IP camera suites and would satisfy their needs. As a result, they get sucked into buying wireless IP surveillance cameras that are beyond what they want.
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 glowing); what accuracy of data do you want to get? (HD images with or without audio tracks) & most importantly, what's your budget?
Secondly, another essential feature to consider before sometimes a wireless IP camera is the skillet and tilt range.
Certainly, this feature will be based upon the environment where you want to use the camera.
A broad pan and tilt range is never a terrible thing.
Thirdly, zooming capability of the wireless IP camera is also vital.
Ensure that you check the sort of zooming capacity, 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 zoom.
Fourth, test the gear before purchase.
That is vital, particularly when you are buying from your local electronic digital store.
Always obtain a test installation 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 gear in an effective manner to make certain you find the best image and audio tracks quality.
