Two Security Cameras that Overcome Difficult Lighting Situations

Images of customers or visitors walking into a room are important surveillance shots to capture. They can also be very difficult images for your security camera to handle since your subject is often moving from bright sunlight into a relatively dark room. The resulting images often show little more than a bright rectangle where the sun is shining in through the entry door. Here are two security cameras that will allow you to capture these difficult images.
Honeywell HCCM474M
Bright Light Operation
The HCCM474M uses backlight compensation to deal with variances in light. With this feature, you can program the camera to ignore hotspots in your picture, such as those created by sun shining through windows and doors. This feature allows the camera to maintain its adjustment to the overall lighting condition of the room.
You can use this security camera with a variety of lenses, which you will have to order and install separately. When using the HCCM474M in bright light situations, choose a manual iris lens. The iris in a camera lens adjusts automatically to let in more or less light. If your camera is aimed at an open door, sun shinng through the door will cause the iris to close in much the same way that bright light causes you to squint. As a result, anyone walking through that open door will appear as a dark silouhette. With a manual iris lens, you can adjust for bright light and then leave the lens locked onto that setting.
Small Size
A physical advantage of this camera is its very small size, making it ideal for covert applications. The camera body is slightly larger than 1.5" wide and 1.5" high so it makes for a very unobtrusive installation.
Speco CVC7WMTD
Bright Light Operation
The Speco CVC7WMTD also utilizes backlight compensation, but it's the electronic shutter that makes it especially useful in bright light situations. The Speco Dome Camera comes with a 4-9mm auto iris lens installed. This lens is ideal for taking a wide view of an entire room, but it can also focus in on a set of double doors. Thanks to the electronic shutter, the auto iris lens works very well in bright-to-dark transitions.
Vandal Resistant Construction
A helpful physical feature, this camera's vandal resistant housing will will survive a blow from a 10lb. sledge hammer. The housing is also weather resistant, making it ideal for outdoor applications.

Using Security Cameras While Respecting Privacy

4 Tips for Implementing a Reasonable Surveillance Policy

 

Preventing internal theft, drug use and workplace violence; these are all valid reasons for using security cameras in the workplace. Such activities can cost your business plenty in terms of lost inventory, decreased productivity and injury. But while you are responsible to protect your company's bottom line, you also need to respect your staff's right to privacy. This article will give business managers and owners some guidelines for using security cameras as part of a reasonable security policy.
Communicate

I know of a company whose IT people installed a web cam on a factory floor. They were preparing for a web cast from a trade show, and wanted to run some tests before going live. The conspiracy theories that started to fly when workers noticed the new camera would have made Jerry Fletcher proud. The camera came down, and fears were laid to rest, but the entire dust up might have been avoided by a simple memo explaining why and for how long the camera would be used. If you plan on deploying security cameras in your organization, please communicate with your employees and explain the new initiative to them. Express your concerns with theft, or safety, or whatever the motivation happens to be and give employees the opportunity to ask questions. This kind of openness will go a long way to alleviate the suspicions that security cameras can raise.
Communicating - whether via email, memo, or company-wide meeting - gives you another advantage. When you require employees to acknowledge your surveillance policy, you may be saving yourself from legal challenges down the road.
Stay Visible In my opinion, security cameras should be kept in full view whenever possible. Not only do visible cameras have a strong deterrent value, but they are another way to encourage trust. Employees may be less likely to believe they are being watched covertly if they know where your cameras are stationed.
However, there are times when covert cameras are necessary. If a crime has been committed, recorded evidence may be necessary to prosecute the crime or prevent further instances. In such cases, a fascinating array of hidden cameras are available. Thanks to advances in miniaturization and wireless technology, cameras can be hidden in computer speakers, smoke detectors, eye glasses, neck ties, pagers, clocks, pens, exit signs and more. Just search on the term "covert cameras" or visit a company like Supercircuits to learn more.
Keep Quiet The recording of audio is restricted under the Electronic Communications Privacy Act of 1986. The legal considerations for recording audio are outside the scope of this article. Suffice it to say that when you record audio, you are essentially wiretapping and you have to meet strict requirements in order to do so legally. Silent video recordings are not covered by the ECPA, so limit your surveillance to video.
Be Reasonable There are certain areas, such as restrooms, that you just shouldn't monitor. The law recognizes a "reasonable expectation of privacy" when considering surveillance issues. Public dressing rooms, restrooms and phone booths are all examples of places designed for privacy, and so a person can reasonably assume they are not being watched in these locations. Public areas such as shopping malls, sports stadiums, hallways and parking lots are not built for privacy and so monitoring and recording in such locations is usually legal. Let common sense be your guide when deciding where to install cameras. If you have questions, it's in your best interest to speak with an attorney familiar with your state's privacy laws before you begin your monitoring program.
