AXIS T8645 PoE+ Over Coax Compact Kit | 01489-001

Model: AXIS T8645

Who This Is For

Property managers specifying IP camera upgrades for buildings that already have coaxial cabling installed will find the AXIS T8645 PoE+ Over Coax Compact Kit directly relevant. Rather than running new Cat5e or Cat6 throughout a site - through walls, ceiling cavities, and conduit - this kit uses the existing coax infrastructure to carry both network data and PoE+ power to IP cameras. That makes it the practical choice for retrofit projects in apartment complexes, commercial buildings, retail sites, and any facility where analogue cameras are being replaced but the cabling is staying. Installers working on tight project budgets or sites where cable re-runs are structurally difficult will recognise the immediate value: reuse what is already in the wall, connect an IP camera at the far end, and maintain PoE+ power delivery without a separate power supply at the camera location.

What This Kit Actually Does

Who Buys This Model

• Electrical and security installers on retrofit contracts: Sites with existing analogue coax cabling where the client wants IP cameras but a full re-cable is not in scope or budget.
• Facilities managers in older commercial buildings: Buildings where coax was installed during original construction and running new structured cabling through finished walls or ceilings is disruptive or cost-prohibitive.
• Strata and body corporate managers: Apartment complexes and multi-tenancy buildings upgrading from analogue DVR systems to IP NVR setups while preserving the existing coax riser infrastructure.
• Project managers on staged migration programmes: Larger sites transitioning from analogue to IP in stages, where the T8645 allows individual camera positions to be upgraded independently without waiting for a full re-cable project.

Honest Assessment

The AXIS T8645 solves a specific and real problem: getting IP cameras and PoE+ power to positions where only coaxial cable exists. For retrofit projects, it can eliminate the single largest cost driver - re-cabling - and that is a meaningful practical advantage. The compact form factor and straightforward transmitter-receiver setup mean installation does not require specialist knowledge beyond a standard security installation skillset. Where this kit does not apply is new installations. If there is no existing coax infrastructure, running Cat5e or Cat6 directly to a PoE switch will always be the simpler and more cost-effective approach. The T8645 is also not a solution for sites where the existing coax is in poor condition, has damaged shielding, or uses non-standard connectors - cable quality will directly affect performance. This product is available through Security Australia as part of the broader AXIS accessories range.

Before You Buy

Quick Fit Check

• Good match if: You are replacing analogue cameras with IP models and the site has existing coaxial cable runs you want to retain rather than re-cable.
• Good match if: The camera position is beyond 100m from the switch and coax already reaches that location - the T8645 extends usable network and power delivery over that existing coax run.
• You may need a different model if: There is no existing coaxial infrastructure on site - for new installations, a direct Cat5e or Cat6 run to a PoE switch is the simpler and more cost-effective solution, and a standard PoE switch or midspan injector from the Security Australia range will be more appropriate.

Key Features & Technical Specifications

Real-World Scenarios

How It Compares

• Choose this if: The site has existing coaxial cabling that reaches the required camera positions, and re-cabling with Cat5e or Cat6 is not practical or not cost-effective.
• You may need a different model if: The site has no existing coax - for new installations, a direct Cat5e or Cat6 run with a PoE+ switch or PoE midspan injector is the more appropriate and simpler infrastructure choice.
• Pairs well with: IEEE 802.3at PoE+ capable network switches, IP cameras with standard RJ45 PoE input, and PoE+ midspan injectors at the head-end where an existing switch is not PoE+ capable.

Common Questions

1. Will this work with any IP camera, or only AXIS cameras?

   It works with any IP camera that accepts a standard PoE+ input via RJ45 - it is not limited to AXIS cameras. The T8645 receiver outputs a standard IEEE 802.3at PoE+ Ethernet connection, which any PoE or PoE+ IP camera can use. The transmitter end connects to any PoE+ capable switch or injector regardless of brand.

2. Does this work with standard PoE switches, or does it need a PoE+ switch specifically?

   It requires a PoE+ switch or injector at the transmitter end. The T8645 is rated to IEEE 802.3at (PoE+), which delivers up to 30W at the switch port. A standard IEEE 802.3af PoE switch only provides up to 15.4W per port, which may not be sufficient to power the transmitter and deliver adequate power to the connected camera. Verify your switch supports 802.3at before installation.

3. What type of coaxial cable does the T8645 require?

   It is designed for standard coaxial cable types including RG-59 and RG-6, which are the coax types most commonly installed in commercial and residential security systems. Non-standard or damaged coax, or coax with excessive connector losses, will affect data throughput and power delivery. Inspect and test the existing cable condition before relying on it for this application.

4. Will this work for a new installation where I want to run coax instead of Cat6?

   It can physically work in that scenario, but it is not the recommended approach for new installations. Running Cat5e or Cat6 directly to a PoE switch is simpler, lower cost, and more future-proof than installing coax and then converting it with the T8645. This kit is specifically designed for sites where coax already exists and cannot be practically replaced.

5. Does the kit include everything needed, or are there additional components required?

   The kit includes the transmitter and receiver units. You will need to supply your own coaxial cable (or use existing coax on site) and appropriate BNC connectors at each end. At the switch end, a PoE+ capable switch or injector is required and is not included. The camera-end receiver outputs a standard RJ45 connection, so no additional adapter is needed between the receiver and the IP camera. The AXIS T8645 is stocked by Security Australia as part of the AXIS accessories range.

6. Does using coax with the T8645 affect video quality or introduce latency compared to direct Cat6?

   No meaningful impact on video quality or latency should be expected under normal operating conditions. The T8645 converts the coax transmission back to standard Ethernet at the receiver end, and the IP camera sees a standard network connection. Performance will be affected if the coax run is damaged, poorly terminated, or significantly exceeds the rated operating distance - in those cases, throughput degradation may occur.
