Nest Cam Braves the Great Outdoors

Nest on Wednesday introduced an outdoor surveillance camera to complement its indoor Nest Cam.

The Nest Cam Outdoor will go on sale this fall for US$199. It is easy to mount on any outdoor surface, according to the company, and even has a magnetic base for attaching to gutters.

The camera, which resembles a unit of track lighting, can capture 1080p video. It has live-streaming capabilities, as well as two-way audio. It has a 130-degree field of view and includes night vision support.

Power to the WiFi camera is provided through a 25-foot cable.

“Nest Cam Outdoor is one of the first, if not the first, security camera to offer features such as Talk and Listen and person alerts,” said Nest Product Manager Mehul Nariyawala.

“It’s the first to offer 24/7 cloud recording — others only offer DVR-based 24/7 recording, which is hard to access when you’re away from home and easy for burglars to steal,” he pointed out.

“It also has the first-ever IP67 rated outdoor adapter, so you don’t have to drill a hole in the wall to install your camera,” Nariyawala told TechNewsWorld.

Camera That Cried Wolf

The outdoor camera uses the same Nest Aware software as its indoor counterpart. It sends alerts of motion and sounds within camera range to users’ smartphones. It also stores video captured by Nest cameras in the cloud — for a fee. Ten days of video history can be stored for $10 a month and 30 days for $30 a month.

With the launch of Nest Cam Outdoor, the Nest Alert software will be improved to allow the system to distinguish between people and other objects in the camera’s view.

“The people-recognition thing is a huge issue, beause I get so many false negatives,” said Bob O’Donnell, chief analyst with Technalysis Research, who owns two of Nest’s indoor cams.

“It becomes like the boy who cried wolf,” he told TechNewsWorld. “I just started ignoring the warnings.”

Nest Cam Outdoor isn’t an exciting product, but it’s a necessary product because the company needs an outdoor camera to be competitive, O’Donnell explained. “There’s no glamour around this product. Anyone could have made it.”

Power Problems

Failure to do more to differentiate the Nest Cam Outdoor from others in the market is a stunning miscalculation, suggested Patrick Moorhead, principal analyst at Moor Insights and Strategy.

“It brings little, if anything, new to the table,” he told TechNewsWorld. “Yet it has many downsides.”

Among the downsides are no solar or battery power support; no support for Apple HomeKit; and no ability to zoom, pan and swivel, Moorhead noted.

The absence of battery power could be a real deal breaker for some consumers, suggested Kevin Krewell, a principal analyst at Tirias Research.

“Think about it. Where are the power outlets on the outside of the house? They’re near the ground where anyone can disconnect the power to the camera,” he told TechNewsWorld.

“They didn’t change the basic functionality of the indoor Nest camera — they just waterproofed it,” Krewell said.

There are some fundamental flaws with battery-powered security cameras, maintained Nest’s Nariyawala.

“They’re easy to install but easy to steal because they’re wireless,” he argued. “They also only start streaming when they detect motion, providing unreliable and limited streaming to save power,” he added.

“In fact, they remain off the majority of the time to conserve power,” Nariyawala pointed out. “A true security camera needs to be standing guard 24/7 — and watch, hear and record everything so you get the full picture.”

Ecosystem Key to Success

On its own, the camera is only a small part of the attraction for consumers, suggested Jonathan Gaw, a research manager at IDC.

“The device itself induces a hard shrug. It’s the Web services behind the devices — the intelligence — that count,” he told TechNewsWorld.

“Nest hopes the intelligence of its cloud services, such as Nest Aware, combined with an ecosystem of connected devices working together will close the deal for consumers,” said Gaw.

The ecosystem is indeed the thing, emphasized Charles King, principal analyst at Pund-IT.

“It gives owners access to value-added features,” he told TechNewsWorld, “including alerts to their smartphones, the ability to speak and listen through the cam via a phone, and automatic storage of video in the Google cloud.”

However, Nest’s cloud storage pricing structure — annual rates of $100 for 10-day video histories and $300 for 30-day ones — may be a turnoff for consumers, he remarked.

“Other cams, like the Netgear Arlo, offer far cheaper cloud storage options,” King pointed out.

While an outdoor version of Nest’s indoor camera makes sense, its consumer appeal is an unknown.

“It’s hard to say how many homeowners are actively looking for a product like this,” King said. “Other applications, such as adapting the Nest Cam Outdoor for business or industrial use, might be more lucrative for Nest.”

CCTV surveillance using Raspberry Pi

Overview

For Security purposes, we usually need to capture every motion in specified areas. To fulfill this requirement, CCTV cameras were introduced a few years ago.

 

However, this brought along some challenges such as the following:

 

  • The ordinary security cameras run continuously, in turn recording everything
  • They need to be monitored 24 hours a day
  • Another major problem with ordinary security cameras is that you need to fast-forward and rewind a lot to find a particular moment / situation

 

Vmoksha’s SolutionRaspberry-Pi
To overcome these issues, Motion activated cameras were introduced. These cameras do not record unless a specified minimum size moves within their range. It stores only potentially relevant video which makes easy to review a particular event.

 

Vmoksha has implemented CCTV Surveillance System by using Raspberry Pi. This system records every motion in a specified area, which can be monitored from any web browser. The camera connected to the Raspberry Pi module detects any kind of motion and capture images. The Raspberry Pi stores the images locally, converts them into a video and uploads that video into Cloud storage such as Dropbox

Components of the Raspberry Pi Module

 

 

Hardware Components

Raspberry Pi: It is a credit-card sized low-cost computer that plugs into a TV or computer monitor and uses a standard keyboard and mouse.

Raspberry Pi Camera Module: It captures high-definition video and still photographs. It is also used to capture slow-motion, time-lapse and other videos.

Power Supply: Raspberry Pi has micro USB connectors to connect the power supply. The requirement for the power supply is 5V and 700mA although it is recommended to use a 1.2A power supply especially if you will be connecting wireless devices or a Wi-Fi dongle.

SD Card: The Raspberry Pi Operating System is loaded and executed from an SD card.

 

Software Components

Raspbian: To run the Raspberry Pi, we need an operating system which is a set of basic programs and utilities. Raspberry Pi foundation recommends installing the Raspbian operating system, a version of Debian Linux that optimizes and uses the Raspberry Pi hardware. This comes with over 35,000 packages, which makes it more than a pure OS. It is precompiled software bundled in an appropriate format for easy installation on your Raspberry Pi. It is still under active development with emphasis on improving the performance and stability of many Debian packages.

Motion Software: This program monitors the video signal from one or more cameras and detects motion. It is able to detect if a significant part of the picture has changed. It is basically made for Linux operating system and is a command line based tool whose output can be PPM, JPEG files or MPEG video sequences. It is the perfect tool to monitor your property because it saves only those images that are really required.

 

How does it work?

A Raspbian image is installed on the SD card and connected to the Raspberry Pi module. The motion software program has also to be installed after this.

The motion software program continuously compares every image with a previously captured image and detects motion. If it recognizes any difference between two images, it starts capturing image and stores those images on an SD card. When motion stops, it converts those captured images to a video.

The Raspberry Pi will then upload the converted videos to the Dropbox cloud storage and delete the uploaded video from SD card. For this uploading and deleting process, we have used Python code.

 

Challenges and Solutions

While implementing this project, we faced some challenges. Read on to know how we faced our challenges with smart solutions:

#

Challenge Solution

1

Initially, the converted videos were not uploading to Dropbox due to a proxy issue We provided full permission to Dropbox

2

Once the video is upload, it was showing up an incorrect time, hence we could not recognize the latest video We used timestamp in the Python code which attaches time to that video file while uploading

 

After a series of challenges and solutions, Vmoksha finally succeeded in implementing CCTV Surveillance by Using Raspberry PI.
