Mercury Wireless Door Entry Phone System 2.4GHz

Very practical and user friendly. I'd recommend this item to others.

You read good reviews on a product but for some reason, once trying to install it, your circumstances always seem to be different and the result is disappointment. I was ready for all this once again with this door phone as it is going to be installed as a replacement for our broken electric gate-opening system. The distance from the outside stone wall of the gate, which is not in-line with the phone (also behind a half metre thick house stone wall) is 50 metres. Could it possibly work and save me the time and expense of digging up the cable to the old system or installing a new one? Yes, it does work and very well at that. The only issue is the sound quality isn't brilliant but it's clear enough.After installing the speaker unit, I covered the areas where it joins the wall with clear silicon and this seems to be effective in stopping water getting in. The speaker unit seems to have the ability to use stepped-down mains power but there is no obvious explanation how to do that so batteries it is. I'll add to this review after a couple of months but for now, very pleased. Note: The unit can't send a signal to open the gate - it is just an intercom -however, we have a remote opener mounted next to the phone and that works fine. Best piece of kit I've purchased in a long time.Update: Four months on, the unit still does the job. The sound quality isn't brilliant as we keep getting echo feedback but it works. The house phone is currently beeping 4 times, once a day. There is nothing about this in the instructions but I'm guessing it's a battery warning for the outside unit. I'll update this further when I'm sure.

This is a very good product. I bought it so that visitors to our house in Greece can call from the gate and gain entry. It was very easy to set up, and works well from the gate to the inside of our house (30 metres approx). I did wonder how weatherproof it would be, but it has survived some amazing storms, and is still working well. If it survives the weather here, it should work anywhere.The only slight problem is that the sound between the caller unit and the indoor telephone echoes a bit. However, it is quite useable. The other thing I noticed is that it does not appear to have the facility to change channels, which might be a problem if there was more than one of these units within wireless range.

I bought to replace existing model which worked well for 3 years but the sound does not work unless max 10m . Also IP44 is not extremely waterproof

A very useful intercom, looks very good, internal unit easy to assemble and fit, outdoor unit needs fixing to a wall or door frame, housing goes first, then the radio unit is fitted, batteries installed then assembled and screwed together, sound quality is acceptable, not Hi-Fi, at least the internal unit can be carried to any room as it has its own batteries, for permanent installation the mains unit is required.

I was expecting that this product was the solution to my problem. Unfortunately, it wasn't. From the front gate to my entrance door there is a distance of 20 meters maybe with an entrance gate and a wall in the middle. As soon as I pass the gate, there is no voice. The bell works fine, but it is impossible to hear anybody.So I will be returning the item and keep looking for other alternatives. No Wifi signal around, so this makes it hard and more expensive to find a wireless solution.

It worked straight away, screwed to the metal post on our locked driveway gates it sat there suffering all weathers without issue.No bother for 9 years, bought in 2016, it was still working fine but some ham fisted bod managed to break the push button so its time was up.In all that time had to change the transmitter batteries twice, quite amazing how long Amazon's own AA batteries lasted.Have replaced with another identical model.In theory it would have been possible to have bought the cheaper wired model and just swapped the switch over, but no complaints 9 years is good going.Its a little bit fiddly fitting it but once in place there's no faffing about getting it to link like some cheap wireless doorbell (been there done that, never again), soon as you fit the batteries in the outside box and plug the phone into the mains it works straight away.Take a tip, if its going outside in all weathers apply a little grease to the screw that holds the front cover in place, you might not need to open it again for 3 years for new batteries.I'd give it 10 stars if that were possible.

Good ebayer..
