If you want to add more power-hungry cameras to your16 port NVR, there are a few options you can consider.
1. Upgrade the Power Supply: One option is to upgrade the power adapter to a higher wattage rating. Since your current power draw is already close to the maximum capacity of the supplied AC adapter, you can look for a higher wattage adapter that can provide sufficient power for the additional cameras. Make sure to check the compatibility and specifications of the NVR before purchasing a new power supply.
2. Use a Power Distribution Box: Another option is to use a power distribution box. A power distribution box allows you to distribute power to multiple devices from a single power source. It can help you overcome the power limitations of your NVR by providing additional power outputs for your cameras. Ensure that the power distribution box is compatible with your NVR and supports the required voltage and current for your cameras.
3. Consider PoE Switches or Injectors: If your NVR supports Power over Ethernet (PoE), you can consider using PoE switches or injectors. PoE switches allow you to connect multiple PoE cameras to a single switch, which can then be connected to your NVR. PoE injectors, on the other hand, can be used to provide power to individual cameras if they do not have built-in PoE support. This can help reduce the power load on your NVR and allow you to add more cameras without exceeding the power capacity.
Remember to always check the specifications and compatibility of any additional equipment you plan to use with your NVR. It's essential to ensure that the power supply and accessories can handle the increased power requirements and are compatible with your existing setup.
