A few months ago I celebrated that I had been at LANACCESS for twenty years, twenty years in the CCTV sector , where I entered the field as a neophyte. I came from the world of fire detection, so my professional life has always been closely related to safety and, more specifically, with Spanish manufacturing companies that have opted for quality and closeness to their customers.

I was one of the technicians who set up the first video recorders LANACCESS , analog video recorders Made in Spain . Current video recorders , which we continue to manufacture entirely in Spain, have great technological differences with those, but there are things that have not changed: their robustness, their reliability and their commitment to safety and efficiency . I myself have also evolved and have gone through different positions within the company. I believe that changing and evolving is vital to be prepared for the new challenges that are going to be presented to us.

Evolution of CCTV systems

In those years, the equipment that existed in the security industry was equipment with VHS tapes. The duration of the recordings was very limited and the tapes had to be changed constantly. They also suffered a lot of wear and tear, which significantly affected image quality.

With the arrival of the digital era, LANACCESS was one of the first companies to offer digital video recorders , also called DVRs ( Digital Video Recorder ) , in which the recordings were stored on hard drives that at that time were around 20 MB, sufficient capacity to store thirty days at CIF resolution (352 x 288) and few images per second. It’s not a big deal compared to today’s standards, but at the time it was a huge leap forward.

While it is true that the technology is still digital, the improvements over the first digital video recorders are evident. Of course, we clearly see that our clients want to continue to have the advantages of having a local video recording system, which leaves the option of the public cloud more restricted to the domestic sphere or to micro-SMEs. We have also observed a bet, in our clients, large companies and critical infrastructures, for the mixed model, that is, for hybrid solutions that allow them to have the best of both worlds, combining, on the one hand, local video recorders with the possibility to use virtualized environments and private clouds . An evolution in which we accompany them from LANACCESS.

A major milestone for video surveillance was the creation of the ONVIF protocol . The ONVIF ( Open Network Video Interface Forum ) committee created in 2008 a communication standard between security devices. The aim was to facilitate the integration of different brands of video equipment, standardizing the communication between them so that they could connect the devices in a simple and almost automatic way . Today, in the interconnected world we live in, the ONVIF protocol is indispensable . But, in addition, customers demand that the solutions have open architectures, to be able to connect different types of systems, and in many cases only ONVIF is not enough. The challenge is to achieve agreat connectivity and at the same time great security , which is not easy to achieve. At LANACCESS we maintain our commitment to open systems and connectivity with third-party solutions that have characterized us since our inception, without neglecting a high level of security.

Evolution in technical support

In the early days of video surveillance, images were always used locally and were often only reviewed afterwards, and it was unthinkable to have live images in a location other than where the cameras were. But that has evolved and today there is practically no video surveillance system that is not connected to a network.

The support has not been alien to this connectivity, and has gone from being only a telephone support to people who were in situ at the facilities to being able to connect remotely (with all security measures and following strict data protection policies) to solve incidents. In this way, agility, quality of service and security have been gained for our clients, their facilities, their clients and their workers. Nowadays, everyone works with the confidence of knowing that not only is there someone in a CRA who can help them in difficult moments thanks to the video surveillance system, but they can also receive specialized technical attention in an agile way , which guarantees them greater system availability.

With the evolution of recorders, computer networks and especially IP cameras, both ur support department as field technicians installers we have had to be forming in new technologies.

The work tools of the installers’ technicians have also changed and, together with the multimeter, screwdriver sets, cable spools and other tools, the laptop has become essential, which has forced technicians to acquire certain knowledge of computers and networks. At LANACCESS, pioneers in this field , we have made every effort to accompany them in this process, providing them with training, especially through courses, but also frequently giving them telephone assistance during the start-up of the facilities.

More recently, thanks to remote desktop connection applications, support is much faster and more versatile . When they authorize us, we connect to the field technicians’ laptops, we see with our own eyes what they see, and in this way we speed up the solution of the problem and we can provide them with more effective feedback.

The evolution of the connectivity available to support it has also been enormous, from the modem or the ISDN – with that peculiar sound of the modem when making the call – and the ADSL to the current bandwidths that fiber provides, or the flexibility that gives a connection via GSM.

The availability of proactive video surveillance solutions such as LANACCESS, with remote connectivity, provides multiple benefits to the customer:

  • Automated equipment monitoring.
  • Remote software and firmware update.
  • Proactivity in incidents.
  • Less travel for field technicians and cost savings.
  • Review of technical alarms, logs.
  • Modification in the configuration (alarms, IP changes, etc.).

Throughout all these years I have witnessed many technological changes, and I myself have changed and adapted. It is a constant process in which you have to listen a lot, train and have solutions that meet the needs of customers.

It is also important to know that what is good today there is no guarantee that it will be good tomorrow. That is why it is necessary to bet on solutions that do not stagnate, that evolve, that are agile and that above all think about customers .
