Walkie Talkie
Push-to-talk over the mobile network (PoC): press one key and the whole team hears you, anywhere in Singapore, with none of the range limits of UHF radios. Rugged Android handsets and 4G keypad radios for hotel, security and logistics teams, with dispatch software, set up and supported by us.
FHD+, 120 Hz, 680 nits peak, Gorilla Glass 3. Runs the PTT app alongside any Google Play app.
Two shortcut keys: set one to push-to-talk, the other to torch, camera or any app.
2 × 4800 mAh. Change a pack without switching off — a call stays connected.
Dual drivers, about 2.6× a normal phone: heard over machinery, traffic and wind.
64 MP main and 20 MP infrared night vision for patrols and inspection; 32 MP front.
Survives 2 m drops, 2 m immersion for 30 minutes and high-pressure wash-down, at about 320 g.
Press and talk to the group. Calls go over 4G, so distance does not matter.
Shows the talk group, who is speaking and the signal.
Physical keys, no touchscreen to learn.
Nationwide coverage over the mobile network, no repeaters to install.
A full shift and more on one charge; explosion-proof build for plant and engineering areas.
Two kinds of handset
Both talk over the same PoC system, so a team can mix them. The choice depends on what else the person needs to do.

Compared with a traditional radio
Island-wide
Over the 4G/5G network, so a basement, a second building or the other side of Singapore are all in range.
Talk groups
Housekeeping, security and engineering each on their own channel, with managers able to reach everyone.
Dispatch and GPS
Dispatch software shows where each handset is, manages the groups and keeps voice logs for audits.
Apps too
The smartphones are Google-certified, so staff can use work apps from Google Play next to the PTT app.

Common questions
What is PoC?
Push-to-talk over cellular: the handset works like a walkie-talkie, but the voice travels over the mobile network, so range is wherever there is 4G or 5G coverage.
Do we need to install repeaters?
No repeaters are needed: PoC uses the mobile network. Each handset uses a mobile data SIM.
Can a supervisor see where staff are?
Yes. The dispatch software shows each handset's GPS position, manages talk groups and records voice logs.
Can staff use other apps on it?
On the rugged smartphones, yes: they are Google-certified and install apps from Google Play next to the PTT app.
What happens when the battery runs low on a shift?
On the rugged smartphone, swap in the second battery without switching off; a call stays connected. The dock charges the handset and both spare packs.
Put together what you need
Choose the handsets and quantities, then send the list on WhatsApp or by email. Nothing is sent until you press send in WhatsApp or your email app.
