Electrical Outlet Camera

Friday, February 18th, 2011

Why would anyone want to have an electrical outlet camera? That’s precisely what you’ll want people to think. That’s what makes the electrical outlet camera so ideal for covert digital video security and surveillance applications.

Half the battle of creating a great, undetectable or covert digital video camera system is having the technology to produce a camera and Digital Video Recorder or DVR small enough to be concealed or disguised in other objects. The other half of the battle of design is finding an object that is so common that the object itself goes unnoticed.

Enter Security Camera King’s “Electrical Outlet Hidden Camera with DVR and 8GB SD Card.”

This electrical outlet camera is actually a collection of technological innovations and it’s not only a camera but a mini digital video security system all in one. There is only one thing this unit won’t do; IT WILL NOT FUNCTION AS AN ACTUAL ELECTRICAL OUTLET. But what it won’t do as far as the outlet is concerned, it more than makes up for in the .

This electrical outlet camera has the appearance of one of those outlet devices that plugs into both outlets on a wall plate, splitting them into a total of six different outlets with ground receptacles. Although the unit does not function as an electrical outlet, it does derive its power from the actual outlet it is plugged into.

The outlet contains a digital video color security camera with a resolution of 380 TVL. In addition it features automatic motion activated recording, scheduled recording, and remote control operation. The recording features include a “time and date stamp” for further documentation accuracy.

The electrical outlet camera’s built in DVR offers plenty of features too. The DVR records to SD card media so the recording capacity time is dependent on the size of the card. An 8 Gigabyte (GB) SD card is included which allows you to record up to 144 hours of video AND audio. However, if that’s not enough, purchase your own additional SD card(s) with a greater capacity (a 16 GB SD card for example) and extend your recording time to up to 288 hours.

The built-in DVR in this electrical outlet camera uses the MPEG-4 CODEC. A Compression/DECompression utility or CODEC is used to compress large digital video files into smaller ones without losing a significant amount of quality. Digital video security cameras actually create their video footage by taking several digital photographs in rapid succession. When played back in rapid succession these photographs fool the human eye into seeing a fluid motion video. Motion video can be created with as few as 12 photographs (also known as “frames) taken every second up to as many as 30 frames per second or fps. The following lists the approximate maximum recording times based on the use of the included 8 GB SD Card:

Resolution at 640 x 480 and 12 fps
• High Quality–approximately 8 hours recording time.
• Medium Quality–approximately 48 hours recording time.
• Low quality– approximately 72 hours recording time; and for

Resolution at 320 x 240 and 30 fps
• High Quality–approximately 16 hours recording time.
• Medium Quality–approximately 96 hours recording time.
• Low Quality–approximately 144 hours recording time.

Once you have finished recording, pull out the easy-to-remove SD card and download the digital video files right to your personal computer where you can view, copy, and/or archive the files. For some computers without a multi-media card reader, you may be required to purchase one of these for your computer.

But that’s not all! The included miniature DVR is more that just a recording device, it can play back the files as well. If you don’t have a computer, you can still view your captured color digital video by using the included RCA cable to connect the unit to your television.

This electrical outlet camera is great for use a home or office security or surveillance camera. Since the unit is totally self-sufficient or a stand alone, that it, it doesn’t require any other devices to work, it can be used in a variety of applications. Retail store merchandise monitoring, employee monitoring in the office, as a nanny cam in the home, and warehouse monitoring are just some of the possible uses for this device.

Remote Video Monitor

Tuesday, February 1st, 2011

Many times digital video security or surveillance applications require remote video monitoring. There are several ways to monitor digital video cameras including the utilization of a professional monitoring service. In this article, we’ll take a look at some of the different methods currently available for remote video monitoring and how they may be used.

Before we talk about remote monitoring, let’s briefly review how a standard system is monitored. An average digital video security system is comprised of digital video cameras, a Digital Video Recorder or DVR and an optional monitor. The cameras are mounted in various locations and each one provides an input to the DVR unit. The DVR than provides the connection and output to a relatively close monitor or monitors. Some systems, such as baby monitors, only use cameras and monitors as recordings are inconsequential.

Although one might argue that many average digital video security systems employ remote monitoring because the monitor is not in the exact same location as the cameras or DVR, our reference to the term generally indicates that the monitor is in an entirely separate location from the cameras and/or DVR and not directly connected by a video transmission wire or cable to either. An example of this could be a wireless digital video entrance gate camera with a monitor located not at the entrance gate, but inside the home several hundred feet away.

To be more accurate, there are different levels of remote monitoring available as well. Both examples above can be examples of relatively close remote monitoring. (Many baby monitor’s cameras for example, transmit wirelessly to a wireless monitor that is located in the same building but a different room — the parents’ bedroom for example). On the other hand, extremely far remote monitoring can be accomplished when someone in Orlando is on vacation in China and monitors their residential digital video security system from their smartphone.

There are several different methods for remote video monitoring of digital video security cameras. The following paragraphs will examine the specific methods currently available.

Wireless Remote Video Monitor
This has been mentioned above however, with current technology, some camera’s boast wireless distance ranges of up to two miles. So not only can the wireless remote video monitor be in near proximity like the baby monitor, but it is possible to reach much farther distances using this method as well.

Some professional remote video monitor services send their signals via more powerful transmitters located at the site being protected and are amplified using various wireless repeaters until the signal reaches their monitoring location, how ever this method is becoming less popular due to the use of the following method.

Internet Protocol (IP) Ready Cameras and DVRs
IP ready cameras and DVRs have their own web server technology built right in to the device and connect to the Internet via a broadband Internet connection such as a modem, router, or WiFi. Although the IP cameras and IP DVRs function slightly differently, the both yield the same result; the ability to remotely monitor the digital video security cameras by way of the Internet.

IP ready cameras are connected directly to the Internet, not to the DVR. They have all the necessary electronic circuitry to do this on their own. Once the camera is installed and connected to the Internet, the user can begin remote video monitoring immediately using a computer or even a smartphone. Not only can IP cameras have a remote video monitor, but even their DVRs can be remotely located to store the digital video files they create.

IP ready DVRs, like the IP ready cameras, are connected directly to the Internet. However, IP ready DVRs manage the coordination of the cameras and recordings locally. That is, the individual cameras are all directly connected to the DVR either wirelessly or via cabling. The DVR then acts as the web server and provides the digital video image to the recipient using the Internet.

Under either Internet Protocol example, the only limiting factor to the remote video monitor is access to the Internet provided to the monitoring device. Even professional remote monitoring services are using IP systems because of the convenience, ease of use, and relatively low cost.

So if you’re looking for a remote video monitor, consider purchasing IP ready cameras or DVRs. If you have any additional questions about a remote video monitor, contact one of our security experts today.
