Home Security in Barnet, Whetstone and Surrounding Areas

If you are looking for a reliable, friendly and professional security company then you have come to the right place! Here at Third Eye Installation Systems we provide home security solutions from burglar alarms, door intercoms, CCTV to security lighting in Barnet, Whetstone and surrounding areas.  The majority of people forget to protect the most expensive investment they will ever buy – their home, but a break-in isn’t just about the financial loss, it can cause huge emotional turmoil.  Locking your windows and doors can be easily overlooked, making your property a target for burglars. It usually takes a serious incident to occur for people to realise the importance of security and a good burglar alarm. So, choosing to improve your home security before such events occur is beneficial to you and your family.

Third Eye Installation Systems are passionate about protecting your home and offer a FREE site survey followed by a FREE quotation for a tailored security solution – giving you complete confidence and a secure home.

We pride ourselves on the quality of our security systems ensuring we serve our customers at affordable prices, starting from just £495+VAT for a 5 zone system which includes the fused spur, 1 live siren bell box at front and 1 decoy at rear – all installed, maintained and guaranteed for 12 months, parts and labour with an NSI Gold Certificate of Conformity.  We think it’s a bargain considering the amount you would spend on repairs following a burglary.

We Offer Home Installations in Barnet and Whetstone

We offer installations such as:

1. Bells-Only System – whereby the siren will ring in the case of an activation

2. Bells with Text Messaging – as in 1. above and the panel would text 4 mobile numbers once we connect the panel to your telephone line or via GSM.

3. Monitored System – our Alarm Reporting Centre (ARC) monitor the alarm 24/7 and call you and/or keyholders in the event of an activation;

4. Monitored with Police Response – as 3. above but the ARC call the Police in the case of 2 confirmed activations (meaning that 2 devices have been activated).


After 1 year we then offer you a 12 month maintenance contract starting from £75+VAT for a bells only system, which gives you reduced call out rates for the year compared to non-contract holders.


We also offer a Takeover Service of your existing system, starting from £85+ for the first hour (excluding parts) which again includes 12 months reduced call out rates.

Our NSI NACOSS Gold accreditation is just one of the many standards that we have achieved – which may help you to get a discount on your home insurance.
