Q: Do you handle both residential and commercial installations?
A: Absolutely. Our proficiency spans both domains.

What exactly is a Security DVR?
A DVR, or Digital Video Recorder, is a cornerstone of modern CCTV systems. It digitizes and stores video feeds from analog or digital cameras on a hard drive, ensuring high-quality, continuous surveillance over extended periods. It has effectively made time-lapse VCRs obsolete.

How does a Security NVR differ?
An NVR (Network Video Recorder) is specifically designed for IP cameras. It captures and stores digital video on a hard drive, similar to DVRs, but is particularly fine-tuned for network camera setups. It’s a progressive step beyond time-lapse DVRs.

What is a video capture card’s role?
It is the heart of a DVR system, converting camera signals into digital video and saving it on a hard drive. Essential for seamless video recording and playback.

What’s the storage capacity for a Security DVR?
This varies based on the number of cameras, their FPS settings, and hard disk capacity. However, our standard configurations usually facilitate multiple weeks of storage in motion detection mode.

How does motion detection operate?
Motion detection in CCTV is primarily software-driven in the DVR or NVR system. It records when there’s a change in pixels, ensuring efficient storage. Users can adjust the sensitivity according to their requirements.

Is live viewing possible locally?
Yes, direct access is facilitated.

What about remote live viewing?
Certainly. The majority of our DVRs and NVRs support internet connectivity, allowing users to access live or recorded footage from any location.

What are the internet requirements for remote access?
A stable DSL or cable internet connection is generally sufficient for most remote viewing needs.

Can multiple users access the same live feed?
Indeed, most of our internet-compatible DVRs and NVRs support multi-user access. It’s worth noting that simultaneous access might spread the available bandwidth.

Audio recording capabilities?
Provided the DVR or NVR system supports audio input, audio can be recorded. As many traditional analog cameras lack built-in audio, an external audio kit might be required.

Is remote audio access facilitated?
Yes, for DVRs and NVRs with audio support and the necessary module, remote audio streaming is possible.

How to determine the number of cameras needed?
It’s a combination of the area’s dimensions and purpose. Generally, one camera per 1000 Sq. Ft. for open spaces, and one per 600 Sq. Ft. for enclosed spaces is a starting benchmark.

Compatibility with existing cameras?
Certainly. Existing CCTV cameras can typically be integrated into our DVR systems, effectively replacing any outdated VCR system.

How to select the appropriate camera lens?
Our selection is vast, but the ideal lens depends on the intended application. Consulting with our technical team will yield the best recommendations.

What benefits does an Auto-Iris Lens provide?
An auto iris lens automatically adjusts its aperture based on light levels, ensuring consistent video quality under fluctuating lighting conditions.

Zoom capabilities?
For zoom functionalities, a PTZ (Pan-Tilt-Zoom) camera is requisite. We offer a diverse range to suit various applications.

Which Operating System do the NVRs run on?
Depending on the model, PC-based NVR systems typically run on Windows 10 or 11 Professional. Standalone DVRs and NVRs generally employ a Linux OS.

Cabling recommendations?
Siamese cable is recommended for its combined RG59 coaxial and 18 gauge wire design, simplifying installations. For IP cameras, cat5 or cat6 is preferred.

What in the event of a power failure?
Most DVRs are designed to resume operation upon power restoration. However, for added safety and surge protection, we recommend using an uninterruptible power supply (UPS).

Cash register (POS) integration?
Our systems are compatible with many PC-based and electronic cash registers. Please share your register details, and we will confirm compatibility.

I hope this suits the tone of a CCTV expert. Let me know if any further adjustments are needed.
