The videophone, also known as the video intercom, is a product that has become more popular in recent years thanks to lower prices, but also thanks to technology that is more accessible to the general public.
The wireless videophone played a big role in the spread of this technology. The absence of wire as well as the battery search of the street panel greatly facilitated the installation. You no longer need to be a computer engineer to be able to install your wireless videophone.
In this article, we will introduce you to the Extel Lesli wireless videophone. Whether you need extra security or just need to see who's ringing your doorbell, the Extel Wireless Video Door Phone is a security device for you!
Extel Lesli wireless video intercom: Technical characteristics
The wireless system of the Extel videophone works using radio waves with GFSK digital modulation. This type of modulation can be used with analog components which are much cheaper than digital components, which explains why this Extel videophone is not expensive.
The Extel Lesli wireless video door phone has an anti-interference system. This type of system is essential for the proper functioning of your wireless videophone. Anti-interference ensures a permanent connection between the street station and the monitor even in severe weather.
The Extel Lesli wireless video intercom has an open field range of 300 meters. Unlike other wired video intercoms whose range does not exceed 120 meters, this wireless video intercom allows you to double the distance between the street station and the monitor but only in open field. Be careful, the range is drastically reduced if you have concrete walls which hinder the radio waves of the wireless system.
The Extel Lesli wireless videophone also has an 18 centimeter diagonal monitor. The most important advantage of the Lesli monitor is its internal rechargeable battery with a battery life of 2 hours in operation and 6 hours in standby. Make sure that the temperature of the monitor does not exceed 40°C and does not fall below 10°C.
The Extel wireless videophone monitor power supply is provided by a 230 V/5 V 1A adapter. Several customers report that the adapter wire can easily be cut, if this happens to you, make sure to respect the polarity otherwise you will have a malfunction of the sound and image.
An electronic box is supplied with the Extel Lesli wireless videophone. This box must be connected to the street panel by a 6-wire cable, it is therefore necessary to install it near the panel. The videophone box ensures the connection with the monitor thanks to an antenna, as well as the power supply of the panel thanks to the battery compartment. It also includes a terminal block for connecting the gate automation as well as a terminal block for connecting the striker or the electric lock.
Extel Lesli Wireless Video Door Phone: Installation Guide
Before starting the installation, choose the locations of the door station and the electrical box. The chosen location must have good air circulation to avoid overheating the box.
It is also preferable to install the case and the board protected from the rain, even if both have rain protection, several customers have complained that the protection is not effective enough.
During installation, it is recommended to:
- Never use rechargeable batteries,
- Never insert the batteries before the installation is complete,
- Pass the cables from the patina and the box through a protective sheath,
- Place the antenna away from any source of interference (metal, tree, obstacle),
- Place the antenna at a height greater than 1.60 meters from the ground,
