Digitally Operating Motion Control Drives

Motion Control drives have one of the most varied applications in the form of digital brushed and brushless servo drives. These drives can be availed in stand alone formats, PCB or panel mounted formats with a choice of bus protocols or simply with control inputs for step and direction and also analogue inputs. With high energy efficient features that pertain to output powers much less than 100W and inclusive of up to 110Kw output. The motion control drives are capable of meeting varied applications that demand, torque loop, speed loop or position loop formats. The drives are completely digital and can work in both current as well as speed and position loops. If we measure their efficiency with respect to size to output power format then the motion control drives will stand out as one of the best in the industry. These drives can be availed with a range of servo motors as per the customers need and requirements with respect to power, size and drive packages. As per client demand, the drives can not only be provided with on-board independent controllers but also with multi axis controllers of the range of Motion Controls.

Main Features of the digital Motion control drives:

The digital Brushed motion control drives from 20W up to 400 Watts. It is capable of taking step and direction or analogue to +/-10V inputs The digital Brushless motion control servo drives from 40W up to 110kW. It can take either step or direction at +/-10V analogue input. The drives can work with either DC or AC generation, in a single or three phase even. They are Ultra Rugged and Compact. These features make them sustainable even in rough manufacturing conditions while ensuring that they do not pose space constrains. The digital motion control drives produce higher efficiency output ranges and are therefore a little costlier than the other control drives. The fully built-in protection adds value to the buyer’s money as these drives require minimum maintenance. The motion control drives are digitally set to comply with ruggedized options in extreme environments. The application areas of the digital motion control drive includes in food and material processing industry, packaging industry, Printing equipment, material handling, film & foil converting, Industrial automation, textile etc. Modern manufacturing industries are slowly getting inclined towards the application of digital motion control drives. The reasons are many, some of which have been discussed above.

All About CCTV Cameras And Their Functionalities

There is a growing demand for CCTV camera installations in both residential and commercial security needs. These cameras work either separately or in combinations with other security solutions like access control or intruder alarm. With the analog camera systems becoming outmoded, consumers find CCTV systems the best choice for their security needs. However, both individuals and businesses find it confusing when it comes to selecting the right choice for their security needs.

The Different Types of CCTV Cameras

There are different types, configurations and styles of CCTV cameras available, giving a wide range to select from, depending on their intended applications and needs.

Dome Camera

The most common type is the Dome Cameras found in indoor security and surveillance applications. The shape of this type makes it difficult to know the direction of facing of these cameras and is ideal to stop criminals in their nefarious plans. The popularity also derives from three reasons, namely:

Easy installation – there are two or three screws required to install most of the dome types. Also, these cameras can be mounted easily on both horizontal and vertical surfaces like walls and ceilings.

Vandal-proof feature: The hardened plastic casing covering the camera protects it from vandalism.

Infrared Capability: there are some dome cameras that have IR illuminators, making it easy to capture video images in low lighting conditions.

Bullet Camera

These cameras have long, tapered, and cylindrical shape as found in a “rifle bullet”, giving it the name. These are used for outdoor applications, where there is a need for long distance viewing. These cameras are installed inside protective casings, protecting them against dirt, rain, hail, dust and other harmful elements. There is a mounting bracket that helps to point the camera in a desired direction. These cameras are fitted with either fixe or varifocal lenses.

C-mount camera

These have detachable lenses that allow users to change lenses according to the need of the applications. For example, the standard CCTV camera lenses can keep an eye between 35 and 40 ft distance, while a C-mount camera using special lenses can cover distances further than that.

Day/Night Camera

These types can work in both normal and faintly-lit environments. As these cameras have an extra sensitive imaging chip capable to capture clear video images in the dark, there is no need for inbuilt infrared illuminators. This makes this camera an ideal choice for outdoor surveillance applications, where IR cameras do not function optimally.

PTZ Security Cameras What Are They and Do I Need One

PTZ’s are a great addition to any security camera system. The key question that you have to ask before you purchase one is… do I need it?

PTZ stands for Pan Tilt Zoom. PTZ cameras can be instructed to pan back and forth, tilt up or down, or zoom in or out. The cameras are controlled locally with a joystick, or remotely via the internet or smart phone application.

This is a truly a great feature in a camera. But a PTZ camera does not solve all your surveillance problems. We have seen many security camera systems that depend too heavily on their PTZs. One obvious issue is that the feature is only useful if a person is available to monitor and adjust the PTZ as needed. Some installations set up their PTZ camera to automatically pan back and forth. But that doesn’t help much if an event occurs outside of the camera’s field of view at any particular moment. Another option to address this issue is an ‘autotracking’ feature which uses analytics to instruct the camera to track and focus in on movement within its field of view. But the autotracking functionality is not fool-proof, and adds cost.

So we recommend that it’s best to think of a PTZ as a bonus camera in your system. Cover all of your area properly with fixed cameras, and then add a PTZ as the “cherry on top”. Now you have proper coverage of all your area and still have the ability to PTZ around your property, either locally or remotely.

Cost of PTZs

Many people think they can save money using a PTZ because it can cover more area. But, PTZs typically cost about 3 or 4 times that of fixed lens camera so they don’t save you money. Plus, since PTZ cameras have moving parts in them they require more upkeep and may not last as long as a fixed lens camera. Maintenance of PTZs might include dome cleaning, belt replacement, and replacement of motor controls, RS485 data board, or zoom module.

Megapixel and Digital PTZ

One last thing to consider is megapixel (mp) cameras. Megapixel cameras record at a much higher resolution than analog cameras and offer a feature called ‘digital PTZ’. When you record a 5mp camera at 2560×1920, you have a lot of pixels that you can digitally zoom in on and move around like a PTZ, both live and during playback. As megapixel cameras become more ubiquitous and affordable the ‘old’ style PTZs will be less desirable.

Conclusion

If all this sounds like we’re trying to talk you out of purchasing a PTZ, we’re not! You just need to be aware of the advantages as well as the drawbacks of using this type of security camera.
