These devices, commonly referred to as Closed Circuit Television Magnifiers or CCTVs, have steadily improved in capability and variety since their commercial production began. CCTVs magnify printed material on a monitor screen or television and magnify it to provide larger reading lines.

Evaluators should carefully consider four features when selecting a portable CCTV: Line Markers, Window Masking, Text to Speech capabilities and Computer compatibility.

1. Optical Character Recognition (OCR)

OCR (Optical Character Recognition) is a feature which digitizes printed text into easily legible words for users or files that can be saved to computers. OCR can be found both on desktop CCTVs and handheld electronic magnifiers.

Contrasting handheld magnifiers, CCTVs provide high magnification and large viewing areas with greater functionality due to being connected with computers or other devices for greater functionality. Some even feature text to speech technology which translates written words into spoken voices.

Home, school and work users have access to a wide variety of desktop CCTVs designed specifically for desktop use, which include features such as line markers, window masking and text to speech options. Some devices even come equipped with USB connections so files from computers or tablets can be uploaded onto the monitor for viewing on its monitor screen.

Portable CCTVs have become increasingly popular recently and their capabilities continue to advance steadily. These units typically come in rectangular form with monitor screens 3 to 5 inches in greatest length; lightweight enough for pocket use; many offer white-on-black, color, freeze frame, variable magnification levels as well as white-on-black features and can save users hundreds of dollars ($300 to $700 less than their desk top counterparts).

Though portable CCTVs may be more convenient than desktop CCTVs, their reliability should still be carefully considered. When selecting a portable CCTV device it’s essential to evaluate its monitor, power source, attachment capabilities, text-to-speech function as well as everyday activities that it will support such as reading from different surfaces or longer reading sessions.

Before providing a veteran with CCTV or EOED devices, the program must first evaluate all available optical and non-optical assistive devices to see if any will meet his/her goals. This should include mobile flat screens and hand-held magnifiers as well as more innovative technologies such as head-mounted display systems. Likewise, an appeal process should also be in place should any veteran be denied such aid.

2. Text to Speech (TTS)

One of the primary functions of CCTVs is magnifying text and images for visually impaired users, making them more legible. They may also enlarge handwriting to improve reading capabilities. Once magnified images have been captured they can be used as computer screen navigation aids or stored onto digital recorders; some CCTVs even come equipped with the ability to read text aloud so users don’t have to read out loud themselves! Some also allow users to listen instead of reading aloud!

CCTVs have long been issued to blinded veterans by the VA for various uses, such as spot checking, reading (mail, books, magazines and newspaper articles), writing medication management programs or managing hobbies and daily tasks.

Portable CCTVs have recently gained in popularity as an innovative type of security monitoring. Resembling laptop computers in size and portability, portables usually feature monitor screens 3 to 5 inches wide at maximum length; many also come equipped with white-on-black, color and freeze frame options like desktop CCTVs – though their screen image may not be as clear and they may be difficult to use for people who lack good hand-eye coordination or experience tremor.

Portable CCTVs may offer another useful feature for students with visual impairments: text-to-speech. To activate this function, the user simply needs to press a key such as Command or Shift; some models even offer keyboard shortcuts which automatically speak highlighted text when such keys are pressed.

Not only can some CCTVs zoom, but some also come equipped with additional useful features, like line markers and window masking (window shading). When linked to a computer, users can transfer documents, images, and text captured from the CCTV for scanning or editing on that system.

Some of the latest CCTVs combine “Screen Readers” and CCTVs, which not only magnify texts but also read them using OCR technology. These systems have wide applications both at home and at work; their combined use makes transporting multiple devices simpler.

3. Video Magnification

Video magnifiers are an assistive technology designed to assist those with difficulty seeing text and objects due to macular degeneration, glaucoma, retinitis pigmentosa, cataracts or other eye conditions. They enlarge printed material or images onto a monitor or television screen for easier reading, shopping, cooking and other hobbies like sewing. With its special camera that focuses on an object before projecting it onto the screen for magnification changes with focus color preference as well as magnification levels and screen preferences for maximum effect.

Portable handheld CCTVs that resemble computer mice are available and easy to use for short-term tasks and daily living needs. Compatible with tablets, laptops and desktops alike, they may even upload the image straight onto a computer for OCR and TTS software (JAWS Fusion OpenBook etc).

Desktop CCTVs with larger monitors offer more options and flexibility, offering a more natural sitting position and possibly offering a moveable tray for writing, placing objects or doing handicrafts. Features may include line markers and window masking to help follow or isolate lines of text; zoom capability with various levels of magnification; color options; reverse modes; freeze frames and contrast/brightness control options.

CCTV magnifiers tend to be among the more costly options for video magnifiers, but could be well worth investing in for those whose traditional optical magnifier no longer meets their needs. A low vision rehabilitation specialist can assess and recommend one according to your budget and needs.

Before purchasing a CCTV magnifier, it is essential to evaluate its functionality and ease of use before making a commitment. Many products provide free trials to give you an opportunity to evaluate before committing. Your local low vision rehabilitation center may have more information regarding CCTV magnifiers or any other assistive technology products; they can recommend those best suited to meet your individual needs as well as train you how to use this type of assistive tech effectively.

4. Accessibility

People living with disabilities frequently rely on assistive technology to meet daily challenges in life. Such equipment enables them to navigate websites, read documents and books, participate in lectures and meetings with their peers and navigate websites more easily. Accessibility contributes significantly to University communities while enriching research and scholarship – it makes learning easier for students with disabilities while keeping them engaged with class!

To make websites accessible for people with visual impairments, they must be built with appropriate contrast and resolution settings. These features allow individuals to adjust color, font size and style of text so that it can be read easily; as well as magnify images and texts for increased reading speed and duration; listen to transcripts of speeches while also using audio guides as navigation aids on screen.

Technology designed to assist those living with disabilities is an increasingly lucrative market. Companies are offering products like CCTVs, scanners and text to speech software that can be used on computers or mobile devices and which aim to help individuals who suffer from visual or physical impairments more independently interact with their surroundings.

CCTV (closed circuit television) cameras are another form of assistive technology designed to magnify text or images for those living with low vision. Although CCTVs tend to be larger and more costly than other forms of assistive tech, they’re increasingly used by people suffering from advanced macular degeneration or severe cataracts; some newer portable CCTVs are smaller and lighter models available for rent at some low vision clinics or Ebay or other online marketplaces.

Government agencies must take great care in making their websites accessible for people with disabilities, both legally and for other reasons such as equality promotion. Accessibility has many positive effects that contribute to improved public services as well as their legitimacy.
