An 16 channel CCTV SMPS (Switched-Mode Power Supply) is a power supply unit designed specifically for surveillance systems that require multiple cameras. Here are some salient features and considerations for an 8-channel CCTV SMPS:

Multiple Channels: The primary feature is the ability to power and manage up to 16 CCTV cameras simultaneously. Each channel provides a separate power output for a camera.

Voltage Regulation: It should provide stable and regulated voltage output to ensure consistent power supply to the cameras. Common voltage options include 12V DC

High Output Current: A sufficient current rating is important to accommodate the power requirements of multiple cameras. Make sure it can deliver enough current for all the connected devices.

Overload Protection: It should have built-in overload protection mechanisms to prevent damage to the power supply unit and connected cameras in case of power surges or excessive current draw.

Short Circuit Protection: Short circuits can occur, and the SMPS should be designed to protect against them to avoid damaging the power supply and cameras.

Surge Protection: To safeguard against voltage spikes and surges from the main power source or lightning strikes, surge protection is essential.

Wide Input Voltage Range: Having a wide input voltage range (e.g., 100-240V AC) makes the SMPS suitable for various regions and power conditions.

Efficiency: Look for an SMPS with high efficiency to reduce energy consumption and heat generation, which can extend the lifespan of the unit.

Multiple Outputs: Some 16 channel CCTV SMPS units come with additional outputs for other surveillance equipment, such as DVRs or NVRs.

Compact Design: A compact and wall-mountable design can save space and make installation easier.

Noise Filtering: Built-in noise filtering can help reduce interference in the CCTV camera feed caused by electrical noise.
