Tips to make the
MOST
out of your order
We understand its a totally new segment for the majority our our customers. So we decided to provide an easily understandable guide on what to look for and how to make purchases effectively

1. Setup to choose
Firstly, it should be decided which setup would suit your needs...
LINKEL AudioVisual Gear
TM
"Video recording/streaming with two-way communication system"
LINKEL AudioMax Gear
TM
"Two-way communication system without video streaming/recording"
TM
LINKEL VisualMax Gear
"Video recording/streaming without two-way communication system"
LINKEL AudioVisual Gear
TM
This package consist of a hidden camera, and two-way communication system (microphone and micro earpiece). This allows your helper to see everything you see, hear everything you hear, and allows you to hear everything your helper says to you, all without anyone noticing anything. This integrated system allows you to have all the support you need during an exam (or in any kind of situation that may require outside surveillance/assistance).

LINKEL AudioMax Gear
TM
This package consist of a two-way communication system (microphone and micro earpiece). This allows your helper to see hear everything you hear, and allows you to hear everything your helper says to you. If video or picture streaming/recording is not necessary, then this setup is sufficient on its own. Otherwise you will need the LINKEL VisualMax Gear as well, to be able to send out visual information to your partner.

LINKEL VisualMax Gear
TM
This package consist of a hidden camera, and a microphone. This system is able to livestream and record video, picture and sound as well, just like the LINKEL AudioVisual Gear. Only exception is, this system doesn't have an earpiece. If two-way communication is not necessary than this setup is sufficient on its own. Otherwise you will need the LINKEL AudioMax Gear as well to be able to hear your partner. Although if you already have some sort of covert earpiece and microphone combo, then this gear will make a great addition to your setup.

2. Battery
To power your needs...
Cap
Our earpiece works with 1.55 V batteries. This battery can power the earpiece for around 5 hours straight. Normally an exam don't usually takes more than 2 hours, we still recommend you use a new battery each time you use the earpiece. You can easily do it since we offer each battery for less than a dollar! Its better safe than sorry!

4. Verdict
- Setup to choose:
For the sake of simplicity, we recommend our user to simply buy the LINKEL AudioVisual Gear, which is easy to operate, as all it needs is a phone nearby with good mobile data signal.
TM
PROS: Easier to operate
CONS: A fast, reliable 4G signal is must.
As an alternative we recommend that you acquire both the LINKEL AudioMax Gear and LINKEL VisualMax Gear.
If getting 2 SIM cards and operating both systems isn't an issue for you, then we would definitely recommend going this way. Also with this route you won't be as dependant on the mobile data as with the LINKEL AudioVisual Gear

TM
PROS: - More foul-proof as the two-way communication will still work even after the internet data is cut-off completely
- Slightly better picture and sound quality
CONS: - A bit more complicated to use - Needs 2 SIM card to operate
Both choices are sensible, so it really just comes down to personal preference regarding the setups. Still we would recommend going with the second choice, since we attach a detailed instruction manual how to operate the "more complicated" system. But no worries it isn't as difficult as it may seem.
- Battery:
As we mentioned above, we recommend using a new battery each time there is an exam. Since the systems only come with 2 batteries, it is recommended to buy AT LEAST ONE additional pack of batteries. One pack consist of 10 pieces of special micro battery (<1$ each) . We sincerely recommend ordering the batteries from us since this exact type is guaranteed to work with the system, also we are a truly cheap source of these batteries.
- Straps:
With the help of the measurement table above, you now will be able to choose which size of the straps would fit you. The camera systems include straps with them. You can choose between black or white desing. We recommend wearing the straps under non-transparent clothing, but still you should wear the black straps under dark shirt, and a white one under light-coloured clothing. You can buy additional straps from us. On request, we also make customised designs for the straps and for the buttons as well. In the instruction manual we include tips on how to conceal cameras on clothing.
+1 Tip : We recommend buying at AT LEAST ONE additional micro earpiece for a spare, if the one earpiece that comes with the setups happen to malfunction, or if you would like to lend it to someone else, it would be more hygenic to use separate earpieces!
