Detailed Information

The VX-451 is an analogue two way radio from Vertex Standard. Built to IP57 standards the radio has a limited Ingres protection against dust, whilst also being submergible in 1 meter of water for up to 30 minutes. MIL-STD-810 C/D/E/F/G ensures the VX-451s reliability, having been put through a variety of tough working conditions in order to test its durability. Coming as standard with a 1380mAh Li-Ion battery, this will allow for up to 10 hours of use in digital mode by the operative.

Lone worker is pre-programmed into the VX-451 helping to ensure the safety of users, if a radio is inactive for a pre-set period of time then an alert will be sent to other radios within the group. Scanning features such as Priority Scan, Dual Watch, Follow-Me and LTR Trunking are available, whilst various signalling types such as CTCSS and DCS are used for the VX-451.

VOX Voice Activation is a ready to go feature of the VX-451. Allowing for hands free communication should it be needed, the radio is capable of performing such feature itself, or via the use of an accessory such as a remote speaker microphone that is VOX compatible. Included in the box alongside the VX-451 is a 1380mAh Li-Ion battery, belt clip, antenna and charger.

Features Explained

Digital Basic Privacy

Basic Privacy uses a fixed "key" which is set when the radio is programmed, of which there are 255 possible "keys". Whilst this level of privacy is technically basic encryption, it's nevertheless relatively insecure. Comparable to analogue 'inversion' scrambling, it will prevent the 'casual' listener from hearing anything, but does not guarantee against eavesdropping.

 Basic Digital Privacy is built-in to the Vertex Standard VX-451.

Voice Activation (VOX)

Voice activation, commonly refered to as VOX, allows the user to initiate the radio to transmit, simply by using their voice. Some radios only allow VOX capability via an external audio accessory such as an earpiece or headset which is VOX-enabled or has a VOX button.

Activating Voice Activation or VOX

There are two possible ways of enabling voice activation (VOX). The first is that we can program a VOX-enable / VOX disable button on the radio. The other option is that we supply an audio accessory, an earpiece or headset, that has a VOX button. Contact us for more information about this.

Programming May Be Required

There may be programming required to activate VOX on your radio. In any event, please talk to our knowledgeable staff and we will be able to offer advice on VOX activation.

 VOX Voice Activation is built-in to the Vertex Standard VX-451.

Channel Scanning

Channel scanning enables the user to monitor a number of channels and respond when a transmission comes through. The scan feature can usually be programmed to include or exclude channels from the scan. Scanning fewer channels makes the scan faster.

A common example is when there is a private channel and community channel programmed. This is usually the case for a shop which is a member of the local business crime reduction (or shop-watch / pub-watch) scheme. The radio would "scan", or alternate between, both channels. Normally, they might only use channel 1 for their own private use within the organisation. But when a transmission (or call) comes through on the local business crime reduction (or shop-watch) scheme channel becomes active. Then within a few seconds the radio would revert back to it's original channel 1.

Digital hybrid radios can usually scan either or both digital and analogue channels simultaneously. This allows for an extremely flexible scan facility where the user can monitor many channels across both analogue and digital modes.

 Channel Scanning is built-in to the Vertex Standard VX-451.

Lone Worker Feature

Lone Worker is a feature found on many two way radios where it's able to send a pre-determined signal, for example a distress call or alarm, to other radios in range, Lone Worker requires some type of interaction from the radio user after a period of radio inactivity. An example of this is the radio can be set to require the radio operator to interact with his or her radio once every 30 minutes. If they fail to do so, their radio will start making an audible sound. If there is still no interaction with his or her radio within 1 further minute, a alarm will sound to other team members to tell them a team member is not responding to Lone Worker. The supervisor can then dispatch another team member to the non-reponsive team member's last known location to offer assistance.

 Lone Worker is built-in to the Kenwood Vertex Standard VX-451.
