Do you offer a free site visit?
Yes. Call or WhatsApp 9597586322 to book a free site visit. We assess your property and recommend the right cameras before you commit.
Can I view my CCTV cameras on my mobile?
Yes. We set up secure live viewing, playback and motion alerts on Android and iOS phones.
How long is CCTV footage stored?
Typically around 30 days, depending on the hard disk size, number of cameras and recording resolution.
Which camera resolution should I choose?
For most homes and shops 2MP (1080p Full HD) is enough. Choose 4MP/5MP or 4K for wide areas, entrances and number-plate or face detail.
Are your HD cameras suitable for outdoor use?
Yes. We install weatherproof outdoor cameras with professional cable routing so they work reliably in rain and heat.
How far can night vision CCTV cameras see?
Our infrared cameras typically see 30 meters or more in complete darkness, depending on the model.
What is colour night vision?
Colour night vision cameras use a sensitive sensor and soft light to record in colour at night instead of black and white.
What is the difference between a DVR and an NVR?
A DVR records analog/HD-coaxial cameras over coaxial cable, while an NVR records IP cameras over network cable. We recommend the right one after a site visit.
How many days of recording can I store?
Typically around 30 days, depending on hard disk size, number of cameras and resolution.
Can I view my CCTV cameras on my phone?
Yes. We configure the recorder and app so you can watch live video and recordings on Android and iOS from anywhere with internet.
Is remote CCTV viewing secure?
We set up password-protected, encrypted access and change default credentials during installation.
How many CCTV cameras does a shop need?
Most shops need 4 to 8 cameras covering the entrance, billing counter, aisles and storage. We plan the exact count during a free site visit.
Can the system grow with my business?
Yes. We install scalable DVR/NVR systems so you can add cameras later.
How many cameras do I need for my house?
A typical independent house needs 4 cameras covering the gate, front door, parking and backyard. Apartments often need 1–2 cameras at the door and balcony.
Can I check my home cameras while travelling?
Yes. Every home installation includes mobile live viewing setup.
Do you handle large factory and warehouse projects?
Yes. We design multi-camera systems with large-area coverage, heavy-duty outdoor cameras and secure recording for factories, warehouses and godowns.
Do you serve industrial areas like Sri City and Gummidipoondi?
Yes. We regularly serve Sri City SEZ, Gummidipoondi SIPCOT, Ambattur and nearby industrial zones.
