Zistos Backwards Compatibility Philosophy and the WXMT-WiFi Module

Zistos Corporation has always tried to keep a philosophy of backward compatibility for any new product that we have ever released. Our feeling is that our customers should not have to throw out their old model product when a new one becomes available. The backwards compatibility design philosophy has allowed our customers to build on their previous investments in our technology and add additional capability to their existing Zistos video tools.

This strategy was possible to implement from a design standpoint, because for many years the analog video technology remained the same across the spectrum of video systems and accessories designed and built by Zistos Corporation. This all changed with the introduction of the ZistosHD line of products. These wireless video systems were designed around digital HD video technology. Digital video has many benefits over analog systems, such as the increased resolution and its ability to transmit encrypted video to other displays and across networks. The very nature of the digital video signals makes them inherently incompatible with our older analog systems.

This is why we designed our WXMT-WiFi module for our older systems that may still be in use by our customers and still have many more years of use left. The WXMT-WiFi module acts like a bridge between our older systems and our newest ZistosHD systems. The WXMT-WiFi can plug into the video output of our older analog WalkAbout display. The device digitizes the analog video and makes it compatible with the newer digital displays that are used on our newest ZistosHD line of video products. This allows the older systems to still have value and allows them to be used to generate wireless, encrypted, digital video images that can be viewed on our wireless 5” and 10” displays.

Our WXMT-WiFi module was designed to provide a way for customers with older systems to benefit from some features of the ZistosHD advanced technology, without having to make a significant investment in an entirely new system.

Features of WXMT-WiFi Module:

  • Small accessory that allows for the connection of wireless HD Tablets to the wired WalkAbout system.
  • Creates wireless a network and allows for the addition of up to 3 HD tablets (running ZistosHD application) in addition to the WalkAbout monitor.
  • Works with ANY Zistos WalkAbout system and connects to ANY ZistosHD Tablet.
  • Connects to our StealthSCOPE & ExplorerSCOPE as well.

Benefits of WXMT-WiFi Module: 

  • No additional system batteries or components required. Only the WXMT-WiFi Module and an HD display.  
  • It allows for a dedicated observer that is focused on the image to decode and report what they see to the operator from afar.
  • The HD tablets, used with the WXMT-WiFi, will work with any future ZistosHD gear purchase.
  • Whether looking for a suspect in a dangerous location, searching for a victim in rubble, checking cargo and vehicles for contraband or industrial inspections, having an untethered second set of eyes is always beneficial.

ZistosHD Tanker Inspection System Benefits:

Are Contaminants Hurting Your Bottom Line?

Contamination has always been a problem within the bulk transportation industry. We can define a contaminant as any object, or substance that renders something impure. In practical terms, it can be described as any substance that is foreign and is not a component of the primary product or material. It can also be an object that is an unintended contact with the primary product or material.

Contaminants can have a negative impact on any type of bulk load, but often have overwhelming consequences when they come into play with food products or supplements intended for human or animal consumption. There are many types of contaminants that can ruin food products that are being transported in bulk. Examples of typical contaminants are fungi, residual heel from previous loads, corrosion, delaminating liners, vermin, and foreign objects such as: tools, phones, lights, pens, etc.

Tank maintenance can play a big role in minimizing potential contamination problems. It is imperative to maintain hygienic conditions in a tank between loads. A tank wash operation is a basic, common sense maintenance that is critical to reducing the risk of contamination. Unfortunately, the reality is the opportunity for contamination can still exist even if a tanker has gone through a tank wash process.

There have been many instances where a fully loaded tanker was contaminated following a proper tank wash procedure:

  • In one case, a rail tanker had gone through an internal tank wash process and had not yet been loaded. A bird flew into the open manway at some point following the wash. The bird was not noticed, and the tanker was filled with a liquid consumable product and it was delivered to a customer at a manufacturing plant. The liquid was used as an ingredient for the manufacture of a snack food and was used for a time before the contaminant was discovered. The resultant discovery created a major disruption to the plant manufacturing process, employee downtime, expensive sanitation procedures, wasted bulk product and transportation costs. Liability for this event went well into the hundreds of thousands of dollars and damaged the reputation and brand of the company that delivered the contaminated product.
  • In another instance, a tank was put through a wash process, but because of a system malfunction, a pocket of the old product remained in the tank. The tank was next filled with a dis-similar product. This led to a cross contamination event that resulted in a mass product recall and many individuals were sickened.
  • There was one occurrence where workmen were repairing a tank interior and accidentally left lithium battery powered utility lights in the tank. The tank was washed but the lights remained in the tank, and it was used to transport a food product. Fortunately, the seals held on the lights and there were no significant negative consequences. This may not have been the case if the lithium batteries were exposed to the liquid food product and it found its way into a pet, livestock or consumer food product.

The one preventative measure that can catch these contamination events and stop them from occurring is to perform a cursory visual inspection of the internal tank conditions just before loading product. This can be problematic as tanks are confined spaces and are inherently dangerous to enter. OSHA has mandated safety procedures to help ensure the well-being of anyone that must break the plane of a confined space environment. A proper and safe confined space entry, requires training, manpower, equipment and administrative oversight. This means that a quick visual inspection can add complexity, cost, and an additional safety concern into the process. 

Zistos has created a video inspection system that can be inserted into a confined space, such as a tanker, to look for these potential contaminants with no entry required. The tanker inspection system, HDTI-5AR-TIP6-3.5Z, can provide a high-resolution image of conditions inside of the tank, viewable by an individual who remains outside of the confined space-envelope.

The ZistosHD tanker inspection system consists of a telescoping pole with a camera on the base. We insert the pole and camera assembly into the tank via the manway. A swivel assembly on the pole spans the manway opening and allows the camera to be manipulated by the user so it can view any area of the interior. The system generates a wireless HD video signal that can be viewed by the inspector, or others, on a body-worn, hands-free, tablet display. It can also be wirelessly transmitted to an existing network and viewed on a supervisor’s computer. The self-illuminating camera also features a 30X optical zoom that can magnify the smallest of suspicious indicators of potential contaminants.

The inspector can scrutinize the interior to make a final decision, just prior to load, that conditions are acceptable and there are no obvious sources of contamination. Inclusion of this video inspection tool in quality control procedures can go a long way in minimizing the potential for many sources of expensive and devastating contamination events. As the old saying goes, “An ounce of prevention is worth a pound of cure”!

Zistos Applies New Technology To Help Reduce Confined Space Entry Accidents

The Occupational Safety and Health Administration (OSHA) introduced the first regulation that protected personnel who work in confined spaces in 1993. Since then, we have come a long way in keeping confined space workers safe but until the number of fatalities from confined space accidents is at zero, there is still room for improvement.

According to a NIOSH study out of the 100 deaths investigated, the main reasons workers entered a confined space were to perform their work functions of routine maintenance, repairs and inspections. Most maintenance/repair operations start by visually inspecting conditions. We design the ZistosHD Tanker Inspection system to reduce the need to enter a confined space, such as a tanker truck, hopper, vault, or rail tanker. It accomplishes this by allowing an individual to make a visual assessment of the interior of the space without the need to enter. The ability to inspect these locations without the need to enter the confined space makes this phase of the process safer and more efficient.

The system (Part #: HDTI-5AR-TIP6-3.5Z), has a self-illuminating color camera head that features a 30X optical zoom. The camera head is attached to a telescopic pole which sits on the man-way and extends down into the confined space and can wirelessly send the video images onto a 5-inch, (optional 10-inch), tablet display. The inspection system can transmit video to off-site personnel and viewed remotely in real-time. In addition, it can capture the images on an SD memory card as still images (jpg), or motion video in 1080P resolution (mp4). The captured images can be stored on a computer for future reference or included in maintenance inspection reports.

OSHA specifies in regulations 1926.1209(e), that if an individual enters into a confined space, (the entrant), that there must be an individual who remains outside of the space, (the attendant), and is specifically tasked with ensuring that the entrant is not in duress. It is the responsibility of the attendant to maintain continuous communication with the entrant.  There is no OSHA mandated procedure on HOW to communicate with the entrant, just that it must be continuous and provided by the employer. Every company has its own method for communication between the entrant and attendant, and it can be as simple as knocking on the side of the tank and listening for a response, but there is no set rule. Camera technology can play a role to increase safety here as well. If following the visual inspection of the confined space it is determined necessary to enter, then the same video inspection system can assist. The OSHA mandated attendant can utilize it to visually monitor the status of the entrant from outside of the space via the video image.

In addition to the video based visual assessment of the entrant, the system also has listen/talk-back capabilities. This facilitates audible communication between the entrant and attendant, and both video and audio can be recorded. Providing a means for the outside attendant to visually confirm the well-being of the entrant and verbally communicate with them makes going into a confined space safer.

Stay safe by using the ZistosHD Tanker Inspection System to inspect the entire interior of a confined space from outside the space. If a confined space entry is unavoidable, keep safe by using this same system as an entrant monitor with live video and two-way audio communication.
