CCTV - Others

Building a reliable surveillance network requires high-quality CCTV accessories. Whether you need PoE splitters to power non-PoE IP cameras, BNC video baluns for analog HDCVI upgrades, or standalone RFID access control keypads, we have the exact hardware. Backed by 20 years of engineering experience in Sham Shui Po, our technical team provides on-site component matching and system design advice to ensure your security infrastructure runs flawlessly without power drops or signal loss.

Security System Infrastructure & Components

Selecting the correct accessories is critical for maintaining stable power delivery and video transmission. Here is a technical breakdown of our core security components:

Component Category Key Technical Features Best Use Case
PoE Splitters & Switches 48V to 12V/5V step-down, IEEE 802.3af/at compliant Powering non-PoE devices (like older IP cameras or routers) via a single Ethernet cable.
Video Baluns & Connectors Passive BNC transceivers, built-in surge protection Transmitting analog HD video (HDCVI/TVI/AHD) over standard Cat5e/Cat6 UTP cables.
Access Control Systems RFID keypads, No-touch IR exit buttons, Maglocks Securing office doors, warehouses, and restricting access to commercial areas.
Alarms & Deterrents Solar tripwires, Dummy cameras with flashing LEDs Cost-effective perimeter defense and strong visual deterrence for intruders.

Important Note (Transmission Limitations & Liability): When using Passive Video Baluns to transmit HD analog video over Cat5e/Cat6 cables, be highly aware of distance limitations. While standard BNC coaxial cables can reach up to 500 meters, passive baluns over UTP typically max out at 200 meters for 1080p and 100 meters for 4K. Pushing beyond these limits will result in severe ghosting or signal loss. Additionally, while dummy cameras are excellent visual deterrents, they cannot replace a real recording system for liability protection and evidence collection.

Frequently Asked Questions (FAQ)

Q: Can I use a PoE splitter to power a standard 12V analog CCTV camera?
A: Yes. If your source is a standard 48V PoE switch, a PoE splitter will step the voltage down to 12V DC to power the analog camera. However, because analog cameras cannot process Ethernet data, the Cat5e/Cat6 cable will act strictly as a power delivery line in this scenario.

Q: How do I choose between a "No-Touch" exit button and a standard mechanical push button?
A: No-touch infrared (IR) sensors are highly recommended for high-traffic areas or environments requiring strict hygiene (like clinics or food processing facilities) to prevent cross-contamination and physical wear. However, IR sensors require a continuous 12V power supply to operate, whereas traditional mechanical push buttons can operate passively to break or close a circuit (NO/NC).
