Top Problems of Using Wi-Fi Security Cameras

Home and business security has moved a notch higher with the terms of surveillance cameras. Wireless security cameras are closed circuit television cameras that send video and audio signals to a wireless transmitter through a radio band. The cameras only require a power code thus the term wireless refers to the transmission of video or audio data. However, there are those cameras that are battery powered making them fully wireless.

As nicely as Wi-Fi security cameras have whole lots of advantages, they are many disadvantages that come along. Here are some of the problems associated with these security cameras:

Overcrowding

Most wireless systems are in the 2.4 GHz frequency bandwidth which is crowded with tons of other devices ranging from wireless PCs, cordless phones, and other Wi-Fi routers. This makes it possible for interference with the reception of the video signals.

Anyone with a 2.4GHz video receiver can pick up the video signal from that wireless camera used in your home. The makers of the camera don't really have a standardized encryption for most consumers wireless security cameras.

Battery Lifespan

WiFi security camera batteries are not appropriate for a prolonged lifespan usage. This is because the wireless camera is powered by a battery and to transmit these signals impel much more than the typical quality of electrical power that a wired protection camera can use to transmit its signals. This kind of transmitting the signals in the camera damages the battery and minimizes its lifespan.
The other reason is since the only wire can be discovered in a wireless safety camera is for battery, wireless cameras are much more likely to be easily stolen if they are placed incorrectly.

Image and Video Quality

Regarding the top quality of images, wireless cameras create a good bad quality of images. This takes happens because of signal interference and lack of light. The wireless cameras are also incapable of starting an excellent record in any outdoor application.

Limitation

A big and major disadvantage of wireless cameras is that they can only monitor a limited and specific area. If the cameras are openly placed, criminals can vandalize the cameras in various ways, by sticking gum on the lens or spraying the view area. If it's reachable, one can be able to adjust the angle of the camera. Criticism from the general public is usually about lack of privacy and the high cost to install for any personal use.

Hacking

The value of wireless surveillance has increased with time, resulting in a higher risk from hackers. Hacking surveillance footages has led to privacy issues, such as images captured by bathroom surveillance of naked people distributing across the internet. It has never been possible to protect the public security systems from hackers. As the surveillance system connects to a network, hackers can hack into the system virtually from other outside locations.

Generally, wireless IP cameras may possibly not be the solution each utilization and situation. Therefore, before acquiring any digital protection cameras', you need to know its positive aspects and drawbacks. Depending on your demands, choose the most suitable plan for you.

Major Benefits Associated With Wireless Cameras

Wireless security cameras are closed circuit television cameras that transmit an audio or video signal to any wireless receiver through a radio band. Modern technology has made security systems possible. When it comes to improving the security of business premises or your home, the market provides consumers with two major options which are the wired and wireless security systems. The wireless ones come with distinct advantages over their traditional counterparts, wired. In past few years, use of wifi surveillance camera has become popular with most of the businesses. No doubt the cameras deliver better results thus a high increase in their demand. Wireless cameras have become an optimal choice when upgrading the existing surveillance systems. Even with the wireless technology, other companies prefer installing wired systems because of the benefits they offer. However, installing cables in a building could be a hassle task.

Some Reasons For Installing a Wifi Camera

The modern world is bringing many changes from analog to digital. The cameras have not been left behind. A good example is the wifi cameras which are not only better but are more affordable even to an average homeowner. Many business premises, offices and homes are upgrading to wifi cameras and so should you.

Many people use these cameras for video recording and surveillance and can access the video footage remotely without the need to stay for long hours in front of the monitor. Certainly, these cameras are among the best out there and very cost effective. The shift to modern cameras like the wireless cameras has brought incredible effectiveness in the way people secure their premises and homes via video monitoring. Many designs of the wireless cameras have inbuilt audio and recording features that eliminate the need for any digital video recorder. An added advantage of these wifi cameras is that it can offer you analytics.

Many of the inbuilt recorders have the ability to store the video and audio footages for more than three months. The cameras have the capacity to compress the images at a high resolution of up to 15 frames each second. Features of video analytic can help to distinguish between cars, people, and animals. In case the record ID is full, one can download the footage into an external storage device such a hard disk. In this article, the author will focus on some few reasons why you should consider installing a WiFi camera.

Cost

The installation cost for these cameras is cheap. No expertise is required while installing such cameras. All you need to do is follow the standard guideline given when you purchase the camera. You can install the camera yourself by following the step by step procedure.

Installation

The cameras are easy to install. All that these cameras require is an ethernet connection and source of power compared to the analog cameras that require many tools and equipment installation. This makes the cameras a better option.

There is no need to worry about drilling holes in the walls and ceiling for wires to pass through, running cables the analog camera to the recorder and securing the digital video recorder. Where one is using the analog camera, some intruders or thieves can steal the digital video recorder to those you don’t have evidence to incriminate them.

Design

The cameras come with a better security camera system design. Compared to analog cameras, wifi camera are more portable. This implies that in most cases, few wifi cameras are needed compared to the number of analog camera that would be required. The cameras are easy to move to different locations on the site of installation. This is time and money saving as you will install fewer camera and require less time to get around.

Software System

There are no additional expenses needed on the software for the security camera system. By using wifi cameras, you save on the excessive costs of buying the software that is used for video analytics. The software is inbuilt. All that is required is to update the software regularly from the manufacturer’s website.

This dramatically saves you some money. The fact that you need to buy a separate digital video recorder will save a substantial amount of money.

There you have it. Buying a Wifi camera does not have to be strenuous. Focus on the important things and your needs will be satisfied.

IP Camera Technology 101: What is it, what are the benefits, Wi-Fi vs PoE

Fierce Telecom has recently reported that more than 24% of American households with broadband Internet connectivity will also have an IP camera by 2020. 

That’s how prevalent IP cameras are.  But what is IP camera technology and what are its benefits?

What is an IP camera?

An Internet protocol (IP) camera is like a closed-circuit television camera in that it is also used for security and surveillance.  The difference lies in the fact that the IP camera can transmit data over the Internet or computer networks.  While the CCTV involves looking at the signals or footage using a monitor, the IP camera is networked and digitized.

An IP camera has a number of advantages over comparable analog technology.  These include:
  • Remote viewing. Remote viewing without having to buy additional hardware/software. Instead of being physically in the same room as the monitors you set up for CCTV cameras, an IP camera can send footage and feeds to any location. That means that whether you are in your bedroom at home or dining at a restaurant in a different state, you’ll still be able to check video clips of the areas covered by your IP cameras. Of course, there are analog cameras that can be paired with a network enabled digital video recorder (DVR) to allow it to be viewed remotely. The DVR is connected to the analog camera and it records the video footage in digitized format, allowing for remote viewing over networks.
  • Enhanced Video Resolution. While traditional analog systems max out at 2-Megapixel resolution, modern IP camera systems are capable of up to 24-Megapixels. This helps with digital zoom allowing for a more detailed image especially useful in applications requiring facial & license plate recognition.
  • Communication device. IP cameras can also work like a two-way intercom, where you can have a conversation over the said platform.  This is perfect for the home, wherein you do not have to open the door to talk to the person knocking outside.
  • Send or store the footage anywhere. Footage can be sent virtually anywhere as long as you have Internet connectivity. IP cameras can record direct to a cloud, on board memory card or a network video recorder (NVR).
  • Adjustable resolution and frame rates.  IP cameras allow you to adjust the camera resolution and frame rate to account for network and bandwidth limitations as well as hard drive and storage limitations.
  • Alerts.  IP cameras can be set up to send you e-mail, SMS or push notifications to alert you of motion and sound activity that it detects.
  • Minimal Cables. Some IP cameras only need a few cables to set up.  You can even go wireless.

Some IP cameras also provide intelligent video.  Intelligent video is a digital technology that comes with an analytical program or software.  This enables you to track a moving person, search for an object, and count the number of people entering your office or home, and trigger alerts or alarms.

All of these benefits do come at the cost of consuming higher bandwidths.  According to IP Video Market Info Inc., IP cameras used in 2012 used up 1 to 2 Mb/s of bandwidth, giving you high-definition video with around six to ten frames per second with a H.264 codec.  If you need higher resolution footage and greater frame rates, then be prepared to provide your IP cameras with more bandwidth. However, you can determine how much available bandwidth you have available and then easily adjust the frame per second and resolution of your IP camera to work within this available bandwidth.  

The benefits of having an IP camera far outweigh the potential disadvantages, which easily plugged anyways.

Wi-Fi vs. PoE

Another area that you should look into when considering security (not just IP cameras) is whether to go wireless or take advantage of Power over Ethernet (PoE).

PoE is when you have a wired Ethernet network that courses electrical current through data cables.  There is no need for power cords and you will be working with lesser wires.  That gives way for lower costs, lower complexity, quick and easy maintenance, and more flexibility with your installation when compared to traditional wiring.  PoE can give you more flexibility with the placement of your cameras because you no longer have to place it near an available socket or install an outlet near the camera. 

You can also remotely manage power supply to your cameras, so you can still maintain those cameras that you have placed out of reach.  It also lowers total cost of ownership.  However, PoE can only produce power of up to 15.4 W and this might not be enough if you have a PTZ IP camera, or those that allow you to pan, zoom and track movements.  Plus, you might want to consider having separate power sources for your IP camera because if there is a problem at the PoE switch, then all your cameras will go down.

Meanwhile, Wi-Fi IP cameras eliminate the need for cables altogether.  You can put up your IP camera in places where it is difficult to lay cables.  But these Wi-Fi networks are prone to interference as well as overcrowding.  That means that your camera may fail to transmit when too many Wi-Fi devices are in used or if somebody operates a Bluetooth device or microwave ovens and other appliance that may interfere with the signal.  You are also limited by the signal strength and availability, and sometimes the packets that you get may not be in order.

This is just the basic information you need when considering IP cameras used to view camera footage remotely via internet connectivity.

IP Security Cameras

An IP camera, or Internet protocol camera, is a type of digital video camera employed for surveillance. Unlike analog CCTV (Closed Circuit Television) cameras, IP cameras can receive and send data via the internet or a computer network. Although a majority of the cameras that do this are webcams, the phrase “netcam” or “IP camera” is normally applied to those used for surveillance.
ip camera

IP camera video technology transmits up to 3MP video resolution over PoE (Power over Ethernet) or Wi-Fi, allowing for cost effective and long distance high-definition video transmission. IP surveillance cameras can assist you to stay in touch with what you adore anywhere, anytime. With the mobile setup process, you will have secure access to your IP camera video stream in no time.

Type of IP Cameras
There is a wide variety of IP surveillance cameras. Let’s journey together in the different types of IP cameras available:

Box Camera
A box camera is an IP camera that is compliant and compatible with third party integrators. The box camera is optimal when you want a specific, small area that you may intend to zoom in closer on since the aim of this camera is fixed in a single direction. The camera comes with no lens, so you will need to separately purchase a mount lens. This IP camera provides cutting-edge technology and leading performance.

Dome Camera (Indoor and Outdoor Camera)
Dome camera is a type of IP camera with a dome cover. The camera is fully featured with HD camera. This camera lens can manually be directly in the desired direction. The camera features both day and night capabilities, with an infra-red that kick in low lighting places. The camera also features the P-Iris lens that makes sure a wide field that allows the background, foreground, and everything in range to be in the targeted focus. The outdoor models feature high ratings in weatherproofing and vandal proofing.

Bullet Camera
The name bullet IP camera comes from relatively small size, as well the general shape of the camera. The bullet IP camera can be used for indoor security or for outdoor security. Outdoor bullet IP cameras are typically placed high to make them less accessible and harder to reach for tampering. Like the dome cameras, the bullet cameras can be adjusted to a specific desired location. They have better zoom capabilities than the dome cameras. Bullet IP cameras are typically rated high in waterproofing, but their design makes them more vulnerable to damage as they lack enclosure design.

PTZ Camera
PTZ stands for Point-Tilt-Zoom. A PTZ IP camera is a camera that is capable of zoom and remote directional control. In television, PTZ controls are used with video cameras in sporting events, television studios, and other places. PTZ cameras can be controlled to any direction you want when you want. It features 10x digital zoom, 20x optical zoom, and a pan feature that allows you to scan a specific area.

IP cameras are relatively new and underdeveloped technology, but in time its improvements to encoding, image processing, and networking technology will surpass over the cost and reliability of analog cameras.

The New Camera Technology - IP Cameras



An IP camera, or Internet protocol camera, is a type of digital video camera employed for surveillance. Unlike analog CCTV (Closed Circuit Television) cameras, IP cameras can receive and send data via the internet or a computer network. Although a majority of the cameras that do this are webcams, the phrase “netcam” or “IP camera” is normally applied to those used for surveillance. 



There are two types of IP cameras. Centralized IP cameras and decentralized IP cameras. Centralized IP cameras require a central NVR (Network Video Recorder) to handle the video, recording and alarm management while the decentralized IP cameras do not require a central NVR, this is because the cameras have a recording function built-in and thus making it record directly to any storage media such as PC/server, network attached storage or SD cards.

Though IP camera is a new technology which has developed quickly in the recent years and even threatens the market of the analog security camera, many customers hold some kind of suspicion about it. In this article, the author illustrates the advantages and disadvantages of IP cameras so as to grasp a better understanding of IP cameras.

The advantages include:

High Image Quality

Image quality is clearly one of the most important features of any camera. Superior image quality enables the user to closely follow changes and details in images, making way for faster and better decisions to more effectively safeguard people and property. It also ensures greater accuracy for automated analysis and alarm tools.

Flexible and cost-effective

Using standard PC server hardware radically reduce equipment costs, particularly for large systems where servers and storage have a significant portion of the total solution cost. IP-based systems provide a means for network video products and other types of applications to share the same wired or wireless network for communicating data.

Remote accessibility
IP cameras can be monitored timely from any computer anywhere in the world, and from many mobile devices including iPhone, laptops, etc.

Encryption and authentication

IP cameras offer the transmission of data through authentication and encryption methods such as WPA, WEP, WPA2, AES, and TKIP.

IP cameras post some disadvantages which may include:

  •  High initial price for high-quality cameras.
  •   Lack of standards. Various IP cameras can encode video differently or use different programming interface, which may require camera recorder combination.
  •   Technical barrier. IP camera requires IP address, network settings, and DDNS, for this services one should hire a specialized technician who is familiar IP cameras.
  •   Network traffic requirement is high. A simple IP video in MJPEG mode requires about 3 Mbit / s.


Amcrest IP cameras are used in an unlimited number of places; however, most of them fall under the security surveillance or remote monitoring of people, property, places and operations. Some typical place that has applied IP cameras includes retail sectors, schools, industries, banks, government offices, etc.

IP camera is relatively new and underdeveloped technology, but in time its improvements to encoding, image processing, and networking technology will surpass over the cost and reliability advantages of analog cameras
