Security camera system reviews?




John


I am shopping an 8 camera security system with night vision and motion recording for a small retail business. I need excellent resolution to capture and record shoplifting and exterior vandalism. I have looked all over the web for system and camera reviews - CNET, Consumer Reports, Google and I can't find objective reviews just sites selling product. Can anyone here make a suggestion? All systems cannot be equal.

Thanks for any advice.



Answer
Hey John

I went to http://searchreviews.com and looked up 5 star rated security cameras. You can see the whole list here: http://searchreviews.com/search.jsp?reviews=security+camera&rating=rating:[5+TO+*]

It looks like you have some good options --- lots of reviews

will x-ray at airport security harm digital camera electronics?

No!

Digital Camera Media Safe In Both Carry-On And Checked Baggage, According To Tests By Imaging Industry And Transportation Security Administration
Travelers Still Strongly Advised to Request Hand Inspection of High-Speed Film

White Plains, N.Y Dec. 15, 2004 â Recent tests found no evidence of X-ray scanner damage to digital camera media cards or to the images they hold. The tests of scanner models currently in use in the U.S. transportation industry were jointly conducted by the International Imaging Industry Association (I3A), the leading global association for the imaging industry; SanDisk Corporation, a manufacturer of digital media cards; and the U.S. Transportation Security Administration (TSA).

These findings mean that digital cameras and their image storage media can travel safely in either checked or carry-on bags, which will be reassuring to holiday travelers. And though they were not explicitly tested, it is likely that images on camera-phones will be safe in either situation as well. More care is needed for cameras with film, however, as the X-ray scanners for both checked and carry-on luggage can fog both developed and undeveloped film.

"Our tests should put travelers' fears to rest, that their digitally captured holiday memories won't be damaged in transit," said Lisa Walker, I3A President. "Digital cameras and media can safely go in carry-ons without the need for hand-inspection, which will simplify security checks and make those long lines move a little faster."

The tests of digital media took place at the TSA Security Laboratory in Atlantic City, N.J. A broad selection of media and devices from a range of manufacturers, loaded with detailed images, was subjected to repeated passes through X-ray scanners matching those now in use at transportation facilities. At the end of the tests, the images were unaltered and the devices showed no sign of damage. Complete details on the tested media cards, test protocols and results can be downloaded from http://www.i3a.org/itip.html.

Separate tests were conducted at the same facility to determine whether the walk-through metal detectors or hand-held metal detector wands have any effect on digital image storage media. As with the X-ray scanners, no damage to media or images was perceived from either of these devices.

The technical support center at SanDisk, a prominent manufacturer of digital media, has been closely monitoring the X-ray issue for several years. As SanDisk ships over a million flash memory cards per week, any issues from security devices would quickly become apparent, but the company has received fewer than a dozen reports per year of problems with airport security systems.

"The Atlantic City lab tests confirm our own observations about the durability of digital media. SanDisk tests have shown that images can be stored indefinitely on flash media cards, without deterioration," said Wes Brewer, SanDisk vice president of consumer products marketing. "In fact, we advise travelers that leaving their images on flash memory cards provides the most durable and dependable method of storing and transporting them. Although the various forms and brands of flash memory cards have different manufacturing processes, consumers who buy recognized brands from reliable sources should have no concerns about traveling with their cards through airport check-points."

The digital media test program is an ongoing initiative of I3A's Integrity in Transportation of Imaging Products (ITIP) Committee, which is composed of representatives from Agfa Corporation, Eastman Kodak Company, Ferrania Imaging Technologies, Fuji Photo Film Co., Ltd., Hewlett Packard Company, Ilford Imaging Group, Konica Minolta, Photo Marketing Association International, Photo-Sensitized Materials Manufacturers Association and Sony Electronics.

ITIP has conducted extensive tests over a period of years to assess the effects of security scanning on film products. Test results to date indicate that the X-ray scanners used for screening carry-on bags will damage high-speed film (ISO 800 or greater). For lower-speed film, the problem appears to be cumulative: the majority of damage has been reported when film has undergone more than five passes through X-ray machines.

Accordingly, I3A advises travelers to request hand inspection of their high-speed (ISO 800 or greater) film products, which is explicitly permitted by law. Hand inspection of lower speed film is recommended only when the film has already been subjected to five trips through X-ray scanners. The screening machines used to screen checked baggage and some cargo will damage all film, regardless of speed. Therefore, I3A and the TSA both advise travelers to carry their film with them and never put it in checked bags.

To help make sure the hand inspection service is consistently available, ITIP has enlisted I3A members in an ongoing effort to gather information on implementation of airport film warnings and advisory signage in U.S. airports; the collected reports are summarized and forwarded to TSA.

"Helping passengers understand how to safely and properly carry their film through security screening is certainly a key element of our customer service efforts at TSA," said Ron Sokolov, Executive Director for Customer Service at the Transportation Security Administration. "Our partnership with I3A has been instrumental in evaluating the impact of our screening technologies on different film media and then getting this information to a wide audience that includes amateur and professional photographers."

When the TSA was established in 2001, I3A formed the ITIP Committee to work with TSA to address the issues arising from the effects on imaging products in transit of increased security measures in transportation. In December 2002, I3A and TSA jointly issued guidelines to help travelers protect their film and cameras from security scanning equipment. ITIP's charter also includes advising authorities specifying and implementing new postal sanitization equipment about its effects on imaging materials and how to protect those materials from damage. I3A's research, reports and guidelines are available to the public at no charge on its Web site, www.i3a.org.

Are computer cameras in our TV sets and Computers spying on us?

Q. The cable connects the TV and Computer and most new ones have little cameras in them so do not you think a hacker(s) could be watching you?
OK -What to do about the camera in the TV?


Answer
The answer, according to research, not so comforting. Devices that can spy, eye opening.
http://rt.com/usa/smart-tv-security-access-092/ ''Viewers, beware: while youâre watching TV, your TV might be watching you back.A security firm discovered that Samsungâs Smart TV can give hackers access to the deviceâs built-in camera and microphones, allowing them to watch everything you do.The Malta-based firm ReVuln posted a video showing its team of researchers hacking into one of the Samsung TVs and accessing its settings, channel lists, widgets, USB drives, and remote control configurations.The security flaw allows hackers to access any and all personal data stored on the TV. âWe can install malicious software to gain complete root access to the TV,â the video writes. With this access, hackers can use the Smart TVs built-in camera and microphones to see and hear everything in front of it. Instead of just watching TV, viewers could themselves be watched without knowing it. But this flaw isnât present in just one specific model.The vulnerability affects all 11 Samsung televisions of the latest generation.The Smart TVs have many of the same features as a computer, but lack the same kind of protection.The devices do not have security features such as firewalls and antivirus software. Fortunately for concerned viewers, the problem has a silver lining: hackers must first breach the network that the television is connected to, as well as know the IP address of the device.As a result, security breaches would likely only occur as a targeted attack against an individual, rather than randomly. Unlike an Internet virus, a hacker would have to exploit the network manually.''

Underwater wireless live streaming Camera?




Kevin


So I am building an underwater ROV and my team needs a camera to mount onto our robot. It needs to be water proof, but if you have to buy a separate box it might be okay. It should be wireless, but we could run a Ethernet cable if we have to. And of course it needs to be able to live stream onto a laptop on the surface of the water.

I have looked into using a Go Pro, but I am unsure of what model to get and Go Pros seem a little pricey, so cheaper options may be better.

Does anyone have any ideas on what i can use? If i use a Go Pro i need to know which model is best, but I would like cheaper options if they exist. Thank You



Answer
Underwater wifi is relatively new and not "readily" available.
http://nypost.com/2013/10/17/yes-underwater-wi-fi-is-a-thing/
at least, not from regular stores. If you are depending on the GoPro wireless connectivity to do what you want, I would bet against it - at least for now. That means some sort of tethered version. As far as I know, there is no wired, direct, "streaming" capability that will do what you want. Remember, the GoPro is a camera/camcorder and designed to capture video locally to a memory card.

Wireless communication is one thing - wireless video is a whole different animal (bandwidth issues in the aquatic/marine environment).

And if you are using a robotic craft, I am guessing the ROV is going to be more than 100 feet away which means if on land, would be on the edge of wifi's reach - underwater, even more so. The GoPros included waterproof housing is rated to only 40 meters (~130 feet).

A camera-only (no local recording), with a cable, solution may be a more do-able option. Since we don't know how deep the camera needs to go and we don't know how far away the camera will be (it could be 5 feet deep but 300 feet away) it is impossible to actually make a recommendation. This shallow, but far away is different than 300 feet deep because of the pressure exerted at that depth.

Your solution may be as simple as
http://www.amazon.com/OceanDrop-Underwater-Training-Observation-Inspection/dp/B007EFG3N2
which is even more than the GoPro. This is an underwater wired camera designed to do what you want. Similar to a security camera, it has a single cable that includes connections for power and the video feed. The power is supplied on the computer side of the cable - the camera does not carry local power. The camera does not store video locally, but sends the video over the wire to an analog/digital converter. This can be a standalone box like those from Blackmagic Design, Roxio, Elgato, Thompson/Grass Valley/Canopus or a card fitted to the computer.

And keep in mind that at about 40ft-50ft and deeper, you will likely need to add light. Underwater lighting can be pricey...
